[0009] The present embodiment will be described below with reference to the drawings. Various features shown in the following embodiment can be combined with each other.

[0010] The program for realizing the software appearing in this embodiment may be provided as a non-transitory computer-readable recording medium, or may be provided so as to be downloadable from an external server, or may be provided so that the program is launched on an external computer and its functions are realized on a client terminal (so-called cloud computing).

[0011] In the present embodiment, the term "unit" may include, for example, a combination of hardware resources implemented by a circuit in the broad sense and software information processing that can be specifically realized by these hardware resources. In addition, in the present embodiment, various information is handled, and this information is represented, for example, by physical values ​​of signal values ​​representing voltage and current, high and low signal values ​​as a binary bit collection consisting of 0 or 1, or quantum superposition (so-called quantum bits), and communication and calculation can be performed on the circuit in the broad sense.

[0012] In addition, a circuit in the broad sense is a circuit realized by at least appropriately combining a circuit, circuitry, a processor, a memory, etc. In other words, it includes an application specific integrated circuit (ASIC), a programmable logic device (e.g., a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA)), etc.

[0013] In this specification, the term "association" includes not only direct association but also indirect association. For example, a state in which element A is associated with element B is a concept that includes not only a state in which element A is associated with element B, but also a state in which element A is associated with element C and element C is associated with element B.

[0014] FIG. 1 is a diagram showing an outline of the configuration of an information processing system 1 according to this embodiment.

[0015] The information processing system 1 includes a user terminal 2, an information processing device 3, and a beauty device 4, which are configured to be able to communicate with each other via an electric communication line. In other words, the information processing device 3 is configured to be able to communicate with the user terminal 2 and the beauty device 4 via a network. Here, the system exemplified by the information processing system 1 is composed of one or more devices or components.

[0016] The user terminal 2 has a communication unit, a storage unit, a control unit, a display unit, an input unit, and an imaging unit, and these components are electrically connected via a communication bus inside the user terminal 2. Descriptions of the communication unit, storage unit, and control unit are omitted because they are substantially similar to the communication unit 31, storage unit 32, and control unit 33 in the information processing device 3.

[0017] The display unit may be, for example, included in the housing of the user terminal 2, or may be externally attached. The display unit displays a screen of a graphical user interface (GUI) that can be operated by the user. It is preferable that such a display unit is implemented by using display devices such as a CRT display, a liquid crystal display, an organic EL display, and a plasma display depending on the type of the user terminal 2. Here, the display unit will be described as being included in the housing of the user terminal 2.

[0018] The input unit may be included in the housing of the user terminal 2, or may be externally attached. For example, the input unit may be implemented as a touch panel integrated with the display unit. If it is a touch panel, the user can input tap operations, swipe operations, and the like. Of course, a switch button, a mouse, a QWERTY keyboard, and the like may be adopted instead of the touch panel. That is, the input unit accepts an operation input made by the user. The input is transferred to the control unit as a command signal via a communication bus, and the control unit can execute a predetermined control or calculation as necessary.

[0019] The imaging unit is a so-called vision sensor (camera) configured to capture information of the outside world. The imaging unit is configured to generate image data by capturing an image of a target. The imaging unit is connected to a communication unit 31 in an information processing device 3 (described later) via a network, and is configured to be able to transfer captured image data to the information processing device 3.

[0020] 2 is a block diagram showing a hardware configuration of the information processing device 3. The information processing device 3 may be in the form of, for example, a server computer. The information processing device 3 may be realized by a plurality of server computers.

[0021] The information processing device 3 includes a communication unit 31, a storage unit 32, and a control unit 33, and these components are electrically connected to each other via a communication bus 30 inside the information processing device 3.

[0022] The communication unit 31 is preferably a wired communication means such as USB, IEEE1394, Thunderbolt (registered trademark), wired LAN network communication, etc., but may also include wireless LAN network communication, mobile communication such as 3G / LTE / 5G, Bluetooth (registered trademark) communication, etc. as necessary. In other words, it is more preferable that the communication unit 31 is implemented as a collection of multiple communication means. In other words, the information processing device 3 communicates various information with the user terminal 2 and the beauty device 4 via the communication unit 31 and through a network.

[0023] The storage unit 32 may be formed by any storage medium, and stores various information defined by the above description. The storage unit 32 may be implemented, for example, as a storage device such as a solid state drive (SSD) that stores various programs and the like related to the information processing device 3 executed by the control unit 33, or as a memory such as a random access memory (RAM) that stores temporarily required information (arguments, arrays, etc.) related to the calculation of the program. The storage unit 32 may also be a combination of these. In particular, the storage unit 32 stores various programs and the like related to the information processing device 3 executed by the control unit 33. Note that the storage unit 32 does not need to be built into the information processing device 3, and may be provided outside the information processing device 3. In this case, the storage unit 32 may be realized by a storage device accessible by the information processing device 3 via a network.

[0024] The control unit 33 performs processing and control of the overall operation related to the information processing device 3. The control unit 33 is, for example, a central processing unit (CPU) not shown. The control unit 33 realizes various functions related to the information processing device 3 by reading out a predetermined program stored in the storage unit 32. That is, the various functions related to the information processing device 3 are realized by the information processing by the software stored in the storage unit 32 being specifically realized by the control unit 33, which is an example of hardware. Note that the control unit 33 is not limited to being a single unit, and may be implemented to have multiple control units 33 for each function. Furthermore, the control unit 33 may be a combination of multiple control units.

[0025] 3 is a diagram showing an external appearance of an example cosmetic device 4. The cosmetic device 4 includes an operating part 4a and a grip part 4b.

[0026] The beauty device 4 is composed of an operating unit 4a and a grip unit 4b that is a support for the operating unit 4a. The operating unit 4a is configured to operate by contacting the user's skin, and is provided at one end of the grip unit 4b in the longitudinal direction. The skin that the operating unit 4a comes into contact with includes, for example, the skin of the upper body. Here, the upper body includes at least one of the face, neck, and chest. That is, it refers to the skin of the upper body above the décolleté. For example, it refers to the face, chin, neck, clavicle, chest, head, etc. Note that it is not necessarily limited to the above-mentioned parts, and may include the back of the neck, abdomen, back, waist, arms, and the lower body such as the buttocks and legs.

[0027] The operating unit 4a may be provided with a plurality of electrodes. In this case, various output waveforms can be applied to the skin through one or more pairs of electrodes, which may be any or predetermined, among the plurality of electrodes. In the example shown in FIG. 3, the plurality of electrodes 40 are arranged on a circular arc, as an example. The arrangement and number of the electrodes 40 are arbitrary, and it is sufficient that at least two or more electrodes are arranged. In addition, a hand electrode (not shown) that can be arranged on the grip unit 4b may be used in a specific process such as iontophoresis.

[0028] The grip portion 4b is a rod-shaped portion that is grasped by a user. The grip portion 4b may be provided with an operation button 4c that is operated by the user when starting or ending the operation of the cosmetic device 4 or when changing the operation mode.

[0029] (Control System) FIG. 4 is a schematic diagram of a control system 100 included in the cosmetic device 4 according to an example.

[0030] In the example shown in FIG. 4, the control system 100 includes a control device 110 and an electric circuit section 200, and the electric circuit section 200 includes a drive circuit section 120, an output waveform generating section 130, and a switching circuit section 140.

[0031] The control device 110 includes a computer and may be formed by, for example, a microcomputer. The control device 110 may operate based on power from a power source 150.

[0032] Based on the control information, the control device 110 controls the drive circuit section 120, the output waveform generating section 130, and the switching circuit section 140 so that an output waveform corresponding to the control information is generated from the multiple electrodes 40.

[0033] The control information is any information that characterizes the output waveform of the output via the multiple electrodes 40. The control information is also any information that the control device 110 uses to output a desired output waveform via the multiple electrodes 40, and may include information used at any stage. For example, the control information may be control signals CT1 and CT2 described below, or a signal itself from the drive circuit unit 120 to the output waveform generating unit 130, or various information for generating these signals. An example of the control information will be described later.

[0034] In the example shown in Fig. 4, the drive circuit section 120 generates various output waveforms via a plurality of electrodes 40. Fig. 4 shows a schematic representation of some waveforms of the control signals CT1 and CT2. In this case, the control signals CT1 and CT2 may be provided to the drive circuit section 120 via separate control lines L1 and L2, respectively. The frequencies (duty ratios) of the control signals CT1 and CT2 may be determined according to control information (the value of a second parameter) described later.

[0035] The drive circuit unit 120 includes a driver that drives a plurality of switching elements Tr, which will be described later. The drive circuit unit 120 generates drive signals for turning on / off the switching elements Tr of the output waveform generating unit 130 in response to control signals CT1 and CT2 from the control device 110, and provides the generated drive signals to the corresponding switching elements Tr.

[0036] The output waveform generating section 130 generates an output waveform based on a power supply 150, which is a DC power supply. The output waveform generating section 130 includes a pair of switching elements Tr and a transformer 135.

[0037] The pair of switching elements Tr are switching elements such as transistors, one of which is connected to a terminal Ta of the transformer 135, and the other is connected to a terminal Tb of the transformer 135. The power supply 150 is connected to a terminal Tc of the transformer 135 related to the center tap. The transformer 135 has a frequency specification adapted to a predetermined frequency. For example, when the induced voltage E of the transformer 135 is E=√2·π·f·n·φm, the frequency f may be set to be approximately equal to the predetermined frequency. In this case, n is the number of turns, and φm is the magnetic flux. The transformer 135 may be adapted to the predetermined frequency based on settings (adjustments) such as changing the set multiplier of the peripheral circuit or the material or degree of adhesion of the ferrite core (an internal component of the transformer 135). The predetermined frequency is preferably a frequency corresponding to a high frequency. In this specification, unless otherwise specified, a high frequency refers to a frequency band greater than 10 kHz, and a low frequency refers to a frequency band equal to or less than 10 kHz.

[0038] The switching circuit section 140 switches the connection destination of the output terminals Td, Te of the output waveform generating section 130 (i.e., the output terminals of the transformer 135) among the plurality of electrodes 40, thereby controlling the electrode pair that generates the output waveform among the plurality of electrodes 40. In this case, the switching circuit section 140 may perform control so that the electrode pair that generates the output waveform changes based on control information described later.

[0039] The control system 100 shown in FIG. 4 is merely an example, and may be modified as appropriate according to the type of control information used (including two or more types). For example, in the switching circuit section 140, the connection destination of the output terminals Td and Te of the output waveform generating section 130 (i.e., the output terminals of the transformer 135) may include other electrodes (not shown), and in this case, the pair of electrodes that generate the output waveform may be switched by time division. Alternatively, two or more systems of the driving circuit section 120 and the output waveform generating section 130 may be provided. In addition, in the case of a configuration in which switching of the pair of electrodes is not required, the switching circuit section 140 may be omitted. In addition, the PWM signal may be applied directly (without going through the control device 110) to the driving circuit section 120 using an oscillator.

[0040] Next, the information processing system 1 will be described in further detail with reference to FIG. 5 and subsequent figures.

[0041] Fig. 5 is an explanatory diagram illustrating an example of data related to control information that is stored in the storage unit 32 of the information processing device 3 according to this embodiment. Fig. 6 is an explanatory diagram of the repeated information in Fig. 5. In Fig. 5 (as well as Fig. 12 described later), "***" indicates a state in which some information is stored, and "..." indicates a state in which similar information is repeatedly stored.

[0042] 5, the storage unit 32 includes, as data related to the control information, association data 500 that associates an object with the control information, and control information data 510. Note that the association data 500 and the control information data 510 are separated for convenience of explanation, and in reality, similar data may be managed in a substantially similar manner. For example, the association data 500 and the control information data 510 may be integrated.

[0043] In the correspondence data 500, an object name and a control information ID are associated with each object ID. The object ID is an identifier given to each object. The object is a substance that can be applied to human skin, and is typically a substance that can be expected to have various effects such as beauty effects. The object may be, for example, various ingredients contained in cosmetics. Alternatively, the object may be various ingredients contained in a skin topical agent. The skin topical agent may be used for any purpose as a substance carrier, such as a medicine or a quasi-drug. The object may also include a substance that is effective in promoting the percutaneous absorption of a medicine that has been metabolized in the liver and has not been able to fully exert its effect in a quasi-drug. Furthermore, the purpose of use of the topical agent to be absorbed percutaneously is arbitrary, and the purpose of the percutaneous absorption of the topical agent is not limited, including analgesics, anti-inflammatory agents, whitening agents, moisturizing agents, anti-wrinkle agents, anti-inflammatory agents, antibacterial agents, and antiviral agents.

[0044] The object name is the name of the substance of the object. The substance name may be a formal name or an abbreviation. Information on the object name may be omitted because it is not directly used for control.

[0045] The control information ID is an identifier given to each piece of control information. Note that one unit of control information may be each control information ID.

[0046] The control information data 510 includes upper data 511 and lower data 512. Note that the upper data 511 and the lower data 512 are separated for the convenience of explanation, and in reality, similar data may be managed in a substantially similar manner. For example, the upper data 511 and the lower data 512 may be integrated.

[0047] In the higher level data 511, each control information ID is associated with mode configuration information, an execution time ratio, a reference execution time, and repetition information.

[0048] The mode configuration information is information that indicates the order in which a plurality of output modes are executed. In this embodiment, the mode configuration information associated with one control information ID includes two or more output modes, but in a modified example, there may be a control information ID associated with mode configuration information including only one output mode.

[0049] For example, in the example shown in FIG. 5, the mode configuration information associated with the control information ID "001" indicates that an output mode M3, an output mode M4, and an output mode M2, which will be described later, are executed in this order.

[0050] The execution time ratio indicates the ratio of the execution time of each output mode indicated in the mode configuration information to each other. Here, the execution time of the output mode executed first is set to a reference value of "1," and the ratio of the execution time of the other output modes is specified. Note that, in other embodiments, information on the execution time itself may be used instead of the ratio of the execution times of the output modes.

[0051] For instance, in the example shown in FIG. 5, the execution time ratio associated with the control information ID “001” indicates that when the execution time of the output mode M3 described below is taken as a reference value “1”, the execution time of the output mode M4 is also “1”, and the execution time of the output mode M2 ​​is “1.2”.

[0052] The reference execution time indicates the execution time related to the reference value. For example, in the example shown in Fig. 5, the execution time is 20 milliseconds, in this case, the execution time of the output mode M3 is 20 milliseconds, the execution time of the output mode M4 is also 20 milliseconds, and the execution time of the output mode M2 ​​is 24 milliseconds.

[0053] The repetition information indicates whether each output mode indicated by the mode configuration information is executed repeatedly (periodically). Here, as an example, "1" indicates that it is executed repeatedly, and "0" indicates that it is not executed repeatedly. If it is executed repeatedly, the number of repetitions and the repetition mode (for example, the presence or absence of an interval and its length, etc.) may be specified.

[0054] For example, in the example shown in FIG. 5, the repetition information associated with the control information ID “001” is “1”, and therefore, as shown in FIG. 6, the output mode M3, the output mode M4, and the output mode M2 ​​are repeatedly executed multiple times in this order.

[0055] In the lower data 512, each output mode is associated with a control parameter for outputting an output waveform related to the corresponding output mode. The control parameters are arbitrary, but in this embodiment, as an example, the control parameters include a first parameter indicating whether the output waveform is an AC waveform or a DC waveform, a second parameter related to frequency, and a third parameter related to amplitude (intensity). Here, as an example, the value of the first parameter is "1" indicating an AC waveform, "0" indicating a DC waveform with positive polarity, and "2" indicating a DC waveform with negative polarity. Note that, when the output waveform is a DC waveform, the value of the second parameter may indicate the frequency of pulse wave generation. Also, in a configuration in which the output intensity is adjustable by the user, the value of the third parameter may function as a default value. Note that the third parameter may be a parameter related to the voltage or duty indicating the output level.

[0056] For example, in the example shown in Fig. 5, output mode M1 indicates that the value of the first parameter is "1" and the output waveform is an AC waveform. Furthermore, output mode M1 indicates that the value of the second parameter is "α1 (actually a specific numerical value)" and the frequency of the AC waveform is α1 [Hz]. Furthermore, output mode M1 indicates that the value of the third parameter is "β1 (actually a specific numerical value)" and the amplitude of the AC waveform is β1 [V].

[0057] In this manner, according to the present embodiment, control information is associated with each object ID. Therefore, it is possible to associate control information capable of generating an output waveform suitable for the characteristics of an object for each object ID.

[0058] Particularly, according to this embodiment, the control information associated with each object specifies output of output waveforms in two or more output modes (output via the pair of electrodes 40 of the cosmetic device 4). In other words, the control information represents processes to be executed continuously in time series by the cosmetic device 4, and processes using output waveforms with different characteristics (two or more types of predetermined processes). This allows detailed processing suitable for each object to be realized.

[0059] Next, the control information will be further described with reference to Figs. 7 to 11 along with some examples of output waveforms with different characteristics.

[0060] Fig. 7 is a diagram showing an example of an output waveform in output mode M1. Fig. 7 shows an output waveform (time series waveform) in output mode M1, with the horizontal axis representing time and the vertical axis representing voltage value. In Fig. 7, ΔT1 represents one period of the output waveform, and is determined according to the value of the second parameter (=α1) described above.

[0061] The output waveform of the output mode M1 is an AC waveform and has multiple peak voltage values ​​during a half cycle (ΔT / 2). In this case, the multiple peak voltage values ​​include a first peak voltage value Vp1 and one or more second peak voltage values ​​Vp2. The second peak voltage value Vp2 occurs preferably 5 to 25 times, more preferably 10 to 20 times, per half cycle.

[0062] The first peak voltage value Vp1 is a peak voltage value that appears at the beginning of a half cycle, and the second peak voltage value Vp2 appears after the first peak voltage value Vp1 and is smaller in magnitude than the first peak voltage value Vp1. The second peak voltage value Vp2 may occur multiple times in a gradually decreasing manner as shown in Fig. 7. The second peak voltage value Vp2 is preferably smaller than half the magnitude of the first peak voltage value Vp1.

[0063] 7 can be formed by setting the value of the second parameter (=α1) significantly lower than the above-mentioned predetermined frequency. In this embodiment, the above-mentioned predetermined frequency is 900 kHz or higher (e.g., 1 MHz), and in this case, the value of the second parameter (=α1) is preferably between 10 kHz and 500 kHz.

[0064] 7A to 7C are diagrams showing other output waveforms that may be used instead of the output waveform of the output mode M1 shown in FIG. 7. FIG. 7D is an enlarged view of the Q6 portion of FIG. 7C. The examples shown in FIG. 7A and FIG. 7C are mainly different from the output waveform shown in FIG. 7 in that the second peak voltage value Vp2 does not exist. In this case, the voltage value of the output waveform for half a period changes in a manner that maintains a substantially constant value (substantially constant voltage value) from the first peak voltage value Vp1. In this case, the substantially constant value may be at a level similar to the second peak voltage value Vp2. Alternatively, the substantially constant value may be at a level slightly smaller than the second peak voltage value Vp2, as shown in FIG. 7C. In this case, the peak waveform related to the first peak voltage value Vp1 has an effect like electroporation, and the subsequent electrical stimulation (section of substantially constant value) can be expected to have an effect of promoting penetration. Note that the substantially constant value is a concept that allows for an error that occurs in a relatively small sawtooth waveform as shown in FIG. 7D, and is a concept that allows for an error of 10% or less from a constant value, for example. Note that in FIG. 7D, B Vp1 represents the magnitude (amplitude) of the first peak voltage value Vp1, and δ represents the fluctuation width of the approximately constant value. Note that although Fig. 7D is a diagram for explaining the approximately constant value in Fig. 7C, the same applies to Fig. 7A.

[0065] The example shown in FIG. 7B differs from the output waveform shown in FIG. 7 mainly in that the first peak voltage value Vp1 does not appear at the beginning of the half cycle but appears midway through. In this case, as shown in FIG. 7B, the second peak voltage value Vp2 may appear at the beginning of the half cycle. In the example shown in FIG. 7B, the first peak voltage value Vp1 appears near the middle of the half cycle, but it may appear significantly later (for example, at the end) (or significantly earlier) than near the middle. This is the same for the output waveforms shown in FIG. 7A and FIG. 7C. That is, in the output waveforms shown in FIG. 7A and FIG. 7C, the first peak voltage value Vp1 does not necessarily have to appear at the beginning of the half cycle, but may appear midway or at the end of the half cycle.

[0066] It should be noted that the various waveforms shown in FIGS. 7 to 7C may be substantially symmetrical in the positive and negative directions, but may have a slight offset on the positive or negative side.

[0067] Here, in various waveforms such as those shown in FIG. 7 to FIG. 7C, the duration of the first peak voltage value Vp1 (ΔT Vp1 ) is preferably determined for a half period (=ΔT / 2) or for the remaining time (=ΔT / 2-ΔT Vp1 ) is less than 1 / 5. That is, ΔT Vp1 ≦1 / 5×(ΔT / 2-ΔT Vp1 ) in the example shown in FIG. 7, the duration (ΔT Vp1 ) is preferably the duration (=ΔT Vp2 =ΔT / 2-ΔT Vp1 ) is 1 / 5 or less. In the example shown in FIG. 7B, the duration of the first peak voltage value Vp1 (ΔT Vp1 ) is preferably the sum of the durations of the two second peak voltage values ​​Vp2 (=2×ΔT Vp2 =ΔT / 2-ΔT Vp1 In these cases, the duration of the first peak voltage value Vp1 (ΔT Vp1 ) may be measured as the period during which 80% or more of the magnitude of the first peak voltage value Vp1 is maintained.

[0068] Fig. 8 is a diagram showing an example of an output waveform in output mode M2. Fig. 8 shows an output waveform (time-series waveform) in output mode M2, with the horizontal axis representing time and the vertical axis representing voltage value. In Fig. 8, ΔT2 represents one period of the output waveform, and is determined according to the value of the second parameter (=α2) described above.

[0069] In output mode M2, a continuous waveform that periodically changes at least twice or more is generated within one duration. In this embodiment, the output waveform of output mode M2 ​​is a pulsed DC waveform. Such an output waveform has a positive polarity and can repel positive ions. Therefore, output mode M2 ​​is suitable for a positively charged object (an object with a positive charge). Note that other output modes with a Repulsion value of "2" may have a waveform with an inverted polarity as shown in FIG. 9. Such an output mode is suitable for a negatively charged object (an object with a negative charge).

[0070] The frequency of the output waveform in output mode M2 ​​(the value α2 of the second parameter) is determined so that at least two or more pulsed DC waveforms are generated within one duration.

[0071] The output waveform of the output mode M2 ​​may be composed of multiple pulse-like DC waveforms with the same amplitude, while the output waveform of the other output modes may include one or more specific pulses whose amplitude (magnitude of voltage value) is significantly larger than the others. For example, FIG. 10 shows an example of an output waveform of another output mode including only one specific pulse PL2 within one duration. The specific pulse has a function of enhancing the penetration effect of an electrically charged object (an object with a positive or negative charge) into the skin by generating a temporary hole in the skin by pulse stimulation (electroporation). In this case, the specific pulse may differ not only in amplitude but also in frequency from pulses other than the specific pulse (hereinafter, for distinction, referred to as "mesoporation pulses") in the output waveform of the output mode M2. Therefore, the control information related to the output mode including the mesoporation pulse may include each value of the second parameter and the third parameter related to the specific pulse. For example, for a mesoporation pulse, the value of the second parameter (=α2) may be set between 1.5 kHz and 10 kHz, and the value of the third parameter may be set so that the peak voltage value is less than 10 V. In contrast, for a specific pulse, the value of the second parameter may be set between 2 Hz and 10 Hz, and the value of the third parameter may be set so that the peak voltage value is 10 V or more. The polarity of the specific pulse may be the same as the polarity of the mesoporation pulse.

[0072] In addition, the output waveform for DC stimulation is not limited to the above-mentioned pulsed DC waveform, and for example, as another output mode, a mode for outputting a constant value DC waveform for a relatively long duration may be set.

[0073] Incidentally, in order to enhance the function of mesoporation pulses, which have the effect of applying a high voltage to push the active ingredient (target substance) into the deeper layers with ions (mesoporation), it may be useful to apply the mesoporation pulse immediately after applying a specific pulse that has the function of generating temporary pores in the skin by pulse stimulation. This is because the temporary pores tend to close up quickly.

[0074] Therefore, the output waveform as shown in Fig. 10 generates a mesoporation pulse immediately after application of a specific pulse, and is therefore suitable for objects that are difficult to penetrate into the deeper layers of the skin with only the mesoporation pulse of output mode M2. As will be described later, it has been found that the output waveforms shown in Fig. 7 (and Figs. 7A to 7C) have similar or even greater effects depending on the object (described later with reference to Figs. 16 and 17).

[0075] Fig. 11 is a diagram showing an example of an output waveform in output mode M3. Fig. 11 shows an output waveform (time series waveform) in output mode M3, with the horizontal axis representing time and the vertical axis representing voltage value. In Fig. 11, ΔT3 represents one period of the output waveform, and is determined according to the value of the second parameter (=α3) described above.

[0076] Here, the output waveform as shown in Fig. 11 can be formed by roughly matching the value of the second parameter (=α3) related to the output mode M3 with the above-mentioned predetermined frequency. For example, when the predetermined frequency is around 900kHz, an AC waveform close to a sine wave can be realized by setting the value of the second parameter (=α3) to around 900kHz, and the heating effect can be improved. Therefore, in this case, the output mode M3 is suitable for a subject for which the effect (effect on the subject) is enhanced by skin heating. Also, in this case, the value of the second parameter (=α1) related to the output mode M1 may be set between 10kHz and 500kHz.

[0077] In this way, the output waveforms of the various output modes can be continuously applied to the skin in various combinations, and therefore, an optimal combination of the various combinations of the various output waveforms (output modes) can be associated with each target object.

[0078] In this case, an optimal combination for each object may be found based on, for example, tests, experience, etc. In this case, various characteristics or properties of the object may be set based on, for example, at least any of (1) properties related to the solubility of the object in a solvent, (2) properties related to charging, and (3) molecular weight or attributes thereof.

[0079] For example, (1) may include properties related to the solubility (or difficulty) of the corresponding object in a specific solvent (e.g., water or oil) (e.g., the property of being water-soluble or fat-soluble, or the property of being water-soluble, fat-soluble (oil-soluble), or amphiphilic at the temperature at which the topical skin preparation is used and the pH (potential hydrogen) of the solution). Also, (2) may include, for example, the number of charges, such as 2, 1, 0, or -1, or alternatively or in addition thereto, properties related to the positive / negative charge or the category of no charge (not dissociated (charged) or ampholyte). Also, it may include properties related to the dissociation mode in an aqueous solution and the acid or base strength thereof. Also, (3) may include the molecular weight itself, or information indicating the category (attribute), such as low molecular weight or high molecular weight.

[0080] For example, for one object, the value related to polarity (i.e., "0" or "2") among the values ​​of the first parameter described above may be set in consideration of the characteristics related to the charging of the one object. In this case, for a positively charged object, a DC waveform of negative polarity (i.e., the value of the first parameter "2") may be set. Also, for a negatively charged object, a DC waveform of positive polarity (i.e., the value of the first parameter "0") may be set. Also, for the one object, the values ​​of the second parameter and the third parameter may be set based on at least one of the properties related to the solubility of the object in a solvent and the molecular weight or its attributes. For example, for a high molecular weight object, the value of the second parameter may be set between 30 kHz and 70 kHz. In this case, it is easy to realize an output waveform with large muscle contraction as an output waveform effective for penetration. Also, for a low molecular weight object, the value of the second parameter may be set between 70 kHz and 200 kHz. In this case, it is easy to realize an output waveform with small muscle contraction but a combined effect with a warming sensation (warming sensation due to a warming effect) as an output waveform effective for penetration.

[0081] More specifically, the control information may be set in a manner as shown in FIG. 12. In FIG. 12, as an example, control information corresponding to six components (objects) is shown, which are niacinamide, tranexamic acid, vitamin C derivative, collagen, hyaluronic acid, and retinol. In FIG. 12, the upper table 1200 shows various characteristics of the six objects and part of the control information (part of the data corresponding to the upper data 511 shown in FIG. 5). For example, for niacinamide, the mode configuration information "M10+M20+M30" is associated. The mode configuration information "M10+M20+M30" indicates that the output mode M10, the output mode M20, and the output mode M30 are executed in this order (or in another order), and the same applies to the others. In the lower table 1202 of FIG. 12, part of the control information (part of the data corresponding to the lower data 512 shown in FIG. 5) is shown. It should be noted that the values ​​of the second parameters shown in FIG. 12 are merely an example and may be adapted according to tests (eg, test results described below with reference to FIGS. 16 to 17H) or the like.

[0082] In the example shown in Fig. 12, the output modes M20, M21, and M30 are processes that can be expected to produce different effects due to the different frequencies even though they have the same AC waveform. For example, as described above, the output mode M21 can be expected to produce a relatively high penetration effect due to relatively large muscle contraction, and can be expected to produce a combined effect with a warm sensation (warm sensation due to the warming effect) even though the muscle contraction is small. In addition, the output mode M30 has a relatively high frequency of the output waveform, as shown by the value of the second parameter, and can be expected to produce a high warming effect.

[0083] Next, an example of the operation of the above-mentioned information processing system 1 will be described with reference to FIG.

[0084] FIG. 13 is a timing chart illustrating an example of the operation of the information processing system 1. As shown in FIG.

[0085] First, the user turns on the power of the beauty device 4 and establishes a connection with the user terminal 2 (Step S1300). Note that the user may have already performed pairing with the user terminal 2 as an initial setting of the beauty device 4.

[0086] Next, the user terminal 2 identifies or estimates one or more objects applied to the user's skin (step S1302). For example, the user inputs information that can identify the cosmetics to be applied to the user's skin this time to the user terminal 2. In this case, the user terminal 2 can identify or estimate one or more objects based on the user input. If the cosmetics used are the same each time (same as the previous time), the input may be omitted, or an input that indicates the same as the previous time may be made. The beauty device 4 may also include a measurement unit (not shown) in the operation unit 4a. In this case, the user terminal 2 can identify the objects contained in the cosmetics based on the measurement results that can be obtained from the beauty device 4. After identifying the objects, the user terminal 2 transmits the identification results to the information processing device 3 (step S1304). In a modified example, the beauty device 4 may directly transmit the identification results to the information processing device 3 instead of the user terminal 2.

[0087] When the control unit 33 of the information processing device 3 acquires the identification result of the object from the user terminal 2 (step S1306), it extracts control information corresponding to the object from the storage unit 32. For example, the control unit 33 identifies a control information ID associated with the object ID corresponding to the object, based on the object ID corresponding to the object, and extracts corresponding control information based on the identified control information ID (step S1308). Then, the control unit 33 transmits the extracted control information to the user terminal 2 (step S1310). In this way, when the control unit 33 acquires the identification result of the object from the user terminal 2 that is the request source (step S1306), it transmits the control information corresponding to the object to the user terminal 2.

[0088] When the user terminal 2 acquires the control information from the information processing device 3 (Step S1312), the user terminal 2 transmits the control information to the beauty device 4 (Step S1314).

[0089] When the cosmetic device 4 acquires the control information, it operates based on the control information (step S1316). For example, in the example shown in FIG. 4 described above, the control device 110 generates a control signal CT1 or the like according to the control information, and applies an output waveform according to the control information to the user's skin via the multiple electrodes 40. Note that the cosmetic device 4 may appropriately perform pre-processing before generating an output waveform according to the control information. In this case, the pre-processing may also be specified by the control information. This is not limited to the pre-processing, but also applies to post-processing and intermediate processing (e.g., processing that may be performed during a repetition interval).

[0090] 13, when the control unit 33 receives the identification result of the object from the requesting user terminal 2 (step S1306), the control unit 33 controls the beauty device 4 via the user terminal 2 based on the control information corresponding to the object (steps S1310 to S1316). Note that in a modified example, when the control unit 33 receives the identification result of the object from the requesting user terminal 2 (step S1306), the control unit 33 may directly control the beauty device 4 based on the control information corresponding to the object without going through the user terminal 2.

[0091] Next, another embodiment will be described with reference to FIG. 14 onwards.

[0092] FIG. 14 is a diagram showing data according to another embodiment that can be used in place of the data (data related to control information) shown in FIG.

[0093] In the example shown in FIG. 14, a characteristic, an object ID, an object name, and a control information ID are associated with each object group ID.

[0094] The object group ID is an identifier given to each group when multiple objects are divided into multiple groups. The multiple objects are preferably grouped in a manner including multiple objects having a common characteristic. In this case, the common characteristic may be at least one of the above-mentioned (1) properties related to the solubility of the object in a solvent, (2) characteristics related to electrostatic charge, and (3) molecular weight or attributes thereof.

[0095] The characteristic associated with the object group ID may be a characteristic shared by the objects belonging to the group associated with the corresponding object group ID. In the example shown in Fig. 14, the characteristics associated with the object group ID are (1) "water solubility" which is a property related to the solubility of the object in a solvent, (2) "positive charge" which is a property related to charge, and (3) "low molecular weight" which is a molecular weight or an attribute thereof.

[0096] Incidentally, a product such as cosmetics may contain multiple objects in one product. In this case, when a user uses the beauty device 4 by applying multiple objects related to one product to the skin, the control information used to control the beauty device 4 may be control information related to at least one of the multiple objects. For example, when control information is associated with a part of the multiple objects, the control information associated with the part may be used. In addition, the control information associated with the object with the highest content (the object listed at the top of the ingredient table) among the multiple objects may be used.

[0097] Alternatively, when one product includes multiple objects, or when multiple products including different objects are used, multiple pieces of control information may be used simultaneously. That is, based on the multiple pieces of control information, multiple output waveforms corresponding to the multiple pieces of control information may be applied to the user's skin via the beauty device 4.

[0098] FIG. 15 is an explanatory diagram of a specific example of control information related to the example shown in FIG. 14. In the example shown in FIG. 15, the control information is associated with each object group, as in the example shown in FIG. 14. In FIG. 15, the control information is shown by a name indicating each output mode. In this case, "MSMP" corresponds to the output mode M1 shown in FIG. 7 (or the output mode related to the output waveforms in FIG. 7A to FIG. 7C), "RF" corresponds to the output mode M30 shown in FIG. 12, "repulsion(+)" corresponds to the output mode M10 shown in FIG. 12, "constant voltage(+)" corresponds to the DC waveform of a constant voltage on the positive side, "repulsion(-)" corresponds to the output mode M11 shown in FIG. 12, and "constant voltage(-)" corresponds to the DC waveform of a constant voltage on the negative side. In addition, "repulsion(+ or -)" may include either one of the above-mentioned "repulsion(+)" and "repulsion(-)" or a combination thereof. Similarly, "constant voltage (+ or -)" may include either one of the above-mentioned "constant voltage (+)" and "constant voltage (-)", or a combination of these. Furthermore, "RF strong" may correspond to an output mode in which the value of the third parameter is large compared to the output mode M30 shown in FIG. 12. Furthermore, "EMS (high frequency)" may correspond to the output mode M20 or M21 shown in FIG. 12.

[0099] Here, with respect to the group of subjects shown in FIG. 15, some examples of useful ingredients of topical skin preparations suitable for penetration are listed.

[0102] Next, test results for some specific objects will be described with reference to Figures 16 through 17H.

[0103] FIG. 16 is a diagram showing the test results when a specific output waveform is applied to a specific object "magnesium ascorbyl phosphate". Specifically, FIG. 16 is a diagram comparing the penetration effect of active ingredients by various output waveforms. In FIG. 16, the vertical axis shows the amount of absorption into the stratum corneum (indicated as "relative value of penetration amount into the stratum corneum" in FIG. 16), and the horizontal axis shows various test conditions C1 to C5, with the amount of absorption into the stratum corneum under each of the test conditions C1 to C5. The amount of absorption into the stratum corneum on the vertical axis is shown as a relative value based on the test condition C1 (the same applies to FIG. 17 and the like). Test condition C1 corresponds to a condition in which no output waveform is generated from the beauty device 4 (hereinafter also referred to as "non-output use condition"). Test conditions C2 to C5 are conditions for using the cosmetic device 4, where test condition C2 corresponds to a condition in which only the output waveform in output mode M3 (see FIG. 11) is applied, test condition C3 corresponds to a condition in which only the output waveform in output mode M2 ​​(positive output waveform shown in FIG. 8) is applied, and test condition C4 corresponds to a condition in which only the output waveform in another output mode (negative output waveform shown in FIG. 9) is applied. Test condition C5 corresponds to a condition in which only the output waveform in output mode M1 as shown in FIG. 7 is applied.

[0104] This test was carried out as follows. 1) First, to check skin homeostasis, the forearm was washed and allowed to acclimate for 15 minutes, after which the amount of water evaporation from the application sites (5 locations) was measured and it was confirmed that there were no significant fluctuations in the values ​​or any injuries. 2) Next, quantitative measurements were performed using the facial beauty device as follows. 2-1: The sample is applied to the forearm. 2-2: After the treatment in 2-1, the device is used for 1.5 minutes in a circular motion at a speed of one rotation per second from above the sample. In addition, under the condition of no output use, the same operation is realized using the beauty device 4 in a powered off state (i.e., the beauty device 4 in a state where no output waveform is generated). 2-3: After the process of 2-2, wipe off the remaining sample with cotton, and then wipe the skin surface with cotton soaked in 50% ethanol solution to wash it. 2-4: After treatment as described in 2-3, the stratum corneum of the application site is peeled off with adhesive tape (a stratum corneum checker commercially available under the trade name "D-Squame (registered trademark)"), and the amount of VCPMg (magnesium ascorbyl phosphate) contained in each of the 2nd to 10th layers of the stratum corneum is quantified.

[0105] In this test, the test was performed starting from test condition C1, taking into consideration the electrical influence of the cosmetic device 4.

[0106] As shown in FIG. 16, it was found that the output waveform of the output mode M1 shown in FIG. 7 is more advantageous than the output waveforms of the other modes in terms of penetrating magnesium ascorbyl phosphate into the stratum corneum.

[0107] From such a test, it is found that when the target is magnesium ascorbyl phosphate or a substance having substantially the same properties as magnesium ascorbyl phosphate (for example, a substance listed in the above-mentioned group of compounds negatively charged in aqueous solution at a pH in the vicinity of weak acidity to weak alkalinity), control information having mode configuration information including output mode M1 is suitable. By performing a test for each component in this way, it is possible to determine which control information is effective, and the control information ID related to the effective control information can be associated with the target.

[0108] FIG. 16A is a table showing further test results for the specific object "magnesium ascorbyl phosphate."

[0109] In Fig. 16A, the test results under test conditions C24 to C31 are evaluated based on the test results under test condition C1, which is a condition where no output is used. The test results are evaluated based on the amount of absorption within the stratum corneum, and the total value of the 1st layer, the 2nd to 5th layers, the total value of the 6th to 10th layers, and the total value of the 2nd to 10th layers are measured.

[0110] The test results are compared for test groups G161 to G165. In test groups G161, G163 to G165, the solution had a pH of 7.5, a concentration of 1.0%, and a use time of 90 seconds. The test groups G161, G163 to G165 had different N numbers, which were 4, 10, 3, and 14, respectively. In test group G162, the solution had a pH of 7.5, a concentration of 1.0%, and a use time of 60 seconds, and N number was 10.

[0111] In the test group G161, the output waveform according to the test condition C24 is an AC stimulation with a frequency of 70 kHz, and the current value is set relatively high. The output waveform according to the test condition C25 is an AC stimulation with a frequency of 70 kHz, and the current value is set relatively low (specifically, half that of the test condition C24). The output waveform according to the test condition C26 is an AC stimulation with a frequency of 50 kHz, and the output waveform according to the test condition C27 is an AC stimulation with a frequency of 156 kHz. From the test results of the test group G161, it can be seen that for magnesium ascorbyl phosphate or a substance having substantially the same properties as it (for example, the above-mentioned substances listed in the group of compounds that are negatively charged in an aqueous solution at a pH level close to weak acidity to weak alkalinity), it is particularly effective in frequency bands such as 70 kHz and 156 kHz. In addition, when comparing the current amounts of 70 kHz (C24, C25), it can be seen that the higher current C24 has a greater penetration amount. In addition, when comparing frequencies (C25, C26, C27), it can be seen that the lower frequency of 50 kHz (C26) has a greater penetration amount. Note that the waveforms of AC stimulation at frequencies of 70 kHz and 156 kHz are the form shown in Figure 7 (waveforms related to output mode M1), but it is expected that similar results will be obtained with waveforms in the forms of Figures 7A to 7C.

[0112] In the test group G162, the output waveform according to the test condition C28 is an AC stimulus with a frequency of 130 kHz, and the output waveform according to the test condition C29 is a combination of an AC stimulus with a frequency of 130 kHz and a negative DC stimulus (frequency according to the second parameter = 10 kHz).The test results of the test group G162 show that these output waveforms are effective for magnesium ascorbyl phosphate or substances having substantially the same properties as magnesium ascorbyl phosphate (for example, substances listed in the above-mentioned group of compounds that are negatively charged in aqueous solution at a pH level around weak acidity to weak alkalinity).

[0113] The output waveform under test condition C30 in test group G163 is negative DC stimulation (frequency associated with the second parameter = 1.5 kHz). The output waveform under test condition C31 in test group G164 is electroporation with a rectangular pulse wave of 20 V (pulse width = 120 usec). The output waveform under test condition C33 in test group G165 is negative DC stimulation (frequency associated with the second parameter = 10 kHz). From these, it can be seen that the higher the frequency, the more effective the negative DC stimulation.

[0114] From such a test, when magnesium ascorbyl phosphate or a substance having substantially the same properties (for example, a substance listed in the above-mentioned group of compounds negatively charged in aqueous solution at a pH in the vicinity of weak acidity to weak alkalinity) is the target, it is found that output waveforms such as the output mode M20 and the output mode M21 described above with reference to FIG. 12 can also effectively penetrate magnesium ascorbyl phosphate or a substance having substantially the same properties into the skin. Therefore, for example, control information having mode configuration information including at least one of the output mode M20 and the output mode M21 may be associated with magnesium ascorbyl phosphate or a substance having substantially the same properties. In this way, by performing a test for each component, it is possible to determine which control information is effective, and the control information ID related to the effective control information can be associated with the target.

[0115] In addition, the control information associated with magnesium ascorbyl phosphate or a substance having substantially the same properties as magnesium ascorbyl phosphate (e.g., a substance that is low molecular weight, water-soluble, and easily negatively charged) may have the following characteristics. That is, the value of the second parameter (=α1) is preferably a frequency of 10 kHz to 500 kHz for the output mode M1 shown in FIG. 7 (or the output modes related to the output waveforms in FIG. 7A to FIG. 7C). More preferably, it is 50 kHz to 160 kHz, and most preferably, it is about 70 kHz. In addition, when combined with other output waveforms, it is desirable to apply 10 kHz to 500 kHz (preferably 10 kHz to 200 kHz) for 40% or more within a predetermined period. In this case, 10 kHz to 500 kHz (preferably 10 kHz to 200 kHz) is preferably applied continuously for 1 second or more. This is because, although the effect can be confirmed even when the application is performed intermittently and repeatedly for less than 1 second, a higher effect was obtained when the application was performed continuously for 1 second or more even if the total time was the same.

[0116] FIG. 17 shows test results when a specific output waveform is applied for a specific target substance "niacinamide (vitamin B3)". In FIG. 17, test conditions C1 to C5 are as described above with reference to FIG. 16. Test condition C6 corresponds to electroporation. In FIG. 17, only the sample is different, but in the case of niacinamide, the time in 2-2 of the test procedure described above is 60 seconds.

[0117] As shown in Figure 17, it was found that the output waveform of the output mode M1 shown in Figure 7 is more advantageous than the output waveforms of other modes in terms of penetrating niacinamide into the stratum corneum. This is expected because the output waveform of the output mode M1 shown in Figure 7 has more electroporation and high frequency elements than the electroporation and high frequency (for example, the output waveform by the output mode M3 (see Figure 11)) alone.

[0118] From such a test, it can be seen that when the target is niacinamide or a substance having substantially the same properties as niacinamide, control information having mode configuration information including output mode M1 is suitable. By performing a test for each component in this way, it is possible to determine which control information is effective, and the control information ID related to the effective control information can be associated with the target.

[0119] Figure 17A is a table showing further test results for the specific subject "tranexamic acid." Figure 17A shows the same test results as Figure 16A described above.

[0120] The test results are compared for test groups G171, G172, and G173. In test groups G171 and G172, the solution had a pH of 7.5, a concentration of 2.0%, and a use time of 60 seconds. The test groups G171 and G172 had different N numbers, with N numbers of 10 and 3, respectively. In test group G173, the solution had a pH of 7.6, a concentration of 2.0%, and a use time of 180 seconds, with N number of 3.

[0121] In the test group G171, the output waveform according to the test condition C45 is an AC stimulus with a frequency of 130 kHz, and the output waveform according to the test condition C46 is a combination of an AC stimulus with a frequency of 130 kHz and a positive DC stimulus (frequency according to the second parameter = 10 kHz). From the test results of the test group G171, it can be seen that these output waveforms are effective for tranexamic acid or substances having substantially the same properties as tranexamic acid (for example, substances listed in the above-mentioned group of compounds that are positively charged in aqueous solution at a pH level close to weak acidity to weak alkalinity). Note that the waveform of the AC stimulus with a frequency of 130 kHz is the form shown in FIG. 7 (waveform according to the output mode M1), but it is expected that the same effect can be obtained with waveforms in the forms of FIG. 7A to FIG. 7C.

[0122] In the test group G172, the output waveform according to the test condition C47 is an AC stimulus with a frequency of 1 MHz, the output waveform according to the test condition C48 is a positive DC stimulus (frequency according to the second parameter = 10 kHz), the output waveform according to the test condition C49 is a negative DC stimulus (frequency according to the second parameter = 10 kHz), the output waveform according to the test condition C50 is an AC stimulus with a frequency of 70 kHz, and the output waveform according to the test condition C51 is electroporation of 20 V.

[0123] In test group G173, the output waveform according to test condition C55 was an AC stimulus with a frequency of 180 kHz, and the output waveform according to test condition C56 was an AC stimulus with a frequency of 130 kHz.

[0124] From such a test, it can be seen that the output waveform such as the above-mentioned output mode M20 and the combination of the output waveform such as the output mode M20 and the output waveform of the positive direct current stimulus can effectively penetrate tranexamic acid or a substance having substantially the same properties into the skin. Therefore, for example, control information having mode configuration information including at least one of the output mode M20 and the combination of the output waveform such as the output mode M20 and the output waveform of the positive direct current stimulus may be associated with tranexamic acid or a substance having substantially the same properties. In this way, by performing a test for each component, it is possible to determine which control information is effective, and the control information ID related to the effective control information can be associated with the target object.

[0125] Also, from the results of the test group G173, the control information associated with tranexamic acid or a substance having substantially the same properties as tranexamic acid (e.g., a substance that is low molecular weight, water-soluble, and easily positively charged) in FIG. 15 may have the following characteristics. That is, the value of the second parameter (=α1) is preferably a frequency of 10 kHz to 500 kHz for the output mode M1 shown in FIG. 7 (or the output mode related to the output waveforms in FIG. 7A to FIG. 7C). And, more preferably, it is 10 kHz to 200 kHz, even more preferably, it is 50 kHz to 180 kHz, and most preferably, it is about 130 kHz. Also, in the case of combination, it is desirable to apply 10 kHz to 500 kHz (preferably 10 kHz to 200 kHz) 40% or more within a predetermined period. In this case, 10 kHz to 500 kHz (preferably 10 kHz to 200 kHz) is preferably applied continuously for 1 second or more. This is because continuous application for one second or more produced a greater effect than intermittent repeated application for less than one second, even though the total time was the same.

[0126] Figure 17B is a table showing further test results for the specific subject "niacinamide." Figure 17B shows the same embodiment of test results as Figure 16A described above.

[0127] The test results are compared for test groups G181 to G185. In test groups G181 to G185, the solution pH was 7.6, the concentration was 2.0%, and the application time was 60 seconds. Among test groups G181 to G185, only test group G184 differed in that N number was 6, while all others had N number of 4.

[0128] In the test group G181, the output waveform according to the test condition C64 is an AC stimulation with a frequency of 1 MHz, and the output waveform according to the test condition C65 is electroporation with a frequency of 20 V. The test results of the test group G181 show that an AC stimulation with a frequency of 1 MHz is effective for niacinamide or a substance having substantially the same properties as niacinamide (for example, the above-mentioned substances listed in the group of compounds that are positively charged in aqueous solution at a pH level around weak acidity to weak alkalinity).

[0129] In addition, the output waveform related to test condition C66 in test group G182 is a negative DC stimulus (frequency related to the second parameter = 10 kHz), and the output waveform related to test condition C68 in test group G183 is a positive DC stimulus (frequency related to the second parameter = 10 kHz).

[0130] In addition, in the test group G184, the output waveform according to the test condition C69 is an AC stimulus with a frequency of 70 kHz, and the output waveform according to the test condition C70 is an AC stimulus with a frequency of 130 kHz. From the test results of the test group G184, it can be seen that the AC stimulus with a frequency of 130 kHz is effective for niacinamide or a substance having substantially the same properties as it (for example, the substances listed in the above-mentioned <group of compounds positively charged in aqueous solution> at a pH in the vicinity of weak acidity to weak alkalinity). Note that the waveform of the AC stimulus with a frequency of 130 kHz is the form shown in FIG. 7 (waveform according to the output mode M1), but it is expected that the same effect can be obtained even with the waveforms of the forms of FIG. 7A to FIG. 7C.

[0131] In addition, in the test group G185, the output waveform related to the test condition C72 is an AC stimulus with a frequency of 130 kHz and a square wave, and the output waveform related to the test condition C73 is an AC stimulus with a frequency of 130 kHz and a waveform in the form shown in FIG. 7 (waveform related to output mode M1). From the test results of the test group G185, it can be seen that for niacinamide or a substance having substantially the same properties as it (for example, a substance listed in the above-mentioned <group of compounds positively charged in aqueous solution> at a pH near weak acidity to weak alkalinity), an AC stimulus with a frequency of 130 kHz is effective regardless of the waveform, and it can also be seen that the waveform shown in FIG. 7 is particularly effective. It can be expected that the effect related to the test condition C73 can be obtained similarly even with a waveform in the form of FIG. 7A to FIG. 7C.

[0132] From such a test, when niacinamide or a substance having substantially the same properties as it (for example, a substance listed in the above-mentioned <group of compounds positively charged in aqueous solution> at a pH in the vicinity of weak acidity to weak alkalinity) is the target, it can be seen that output waveforms such as the output modes M20 and M30 described above with reference to FIG. 12 can effectively penetrate niacinamide or a substance having substantially the same properties into the skin. Therefore, for example, control information having mode configuration information including at least one of the output modes M20 and M30 may be associated with niacinamide or a substance having substantially the same properties as it. In this way, by performing a test for each component, it is possible to determine which control information is effective, and the control information ID related to the effective control information can be associated with the target.

[0133] Figure 17C is a table showing the results of another test on the specific subject "kojic acid." Figure 17C shows the results of the same test as in Figure 16A above, but with the substance changed to kojic acid.

[0134] The solution pH was 6.5, the concentration was 1.0%, the usage time was 60 seconds, and the number of subjects was 3. The output waveform according to test condition C80 was an AC stimulus with a frequency of 1 kHz, the output waveform according to test condition C81 was an AC stimulus with a frequency of 130 kHz, the output waveform according to test condition C82 was an AC stimulus with a frequency of 10 Hz, and the output waveform according to test condition C83 was an AC stimulus with a frequency of 90 kHz.

[0135] From these tests, it was confirmed that kojic acid or substances with similar properties (e.g., low molecular weight, water soluble, almost uncharged in aqueous solution) have a penetrating effect even at frequencies other than high frequency.

[0136] Therefore, the control information associated with kojic acid or a substance having properties similar thereto (e.g., a substance that is low molecular weight, water soluble, and hardly charged in an aqueous solution) may have the following characteristics: For example, the value of the second parameter (=α1) is suitable for AC stimulation of 200 kHz or less, and preferably 10 Hz to 130 kHz, for output mode M1 shown in Fig. 7 (or output modes related to the output waveforms in Figs. 7A to 7C).

[0137] Figure 17D is a table showing the results of another test on the specific object "arbutin." Figure 17D shows the results of the same test as in Figure 16A above, but with the substance changed to arbutin.

[0138] The output waveform for test condition C100 is an AC stimulus with a frequency of 1 MHz, the output waveform for test condition C101 is a positive DC stimulus, and the output waveform for test condition C102 is a negative DC stimulus. The output waveform for test condition C103 is an AC stimulus with a frequency of 70 kHz, and the output waveform for test condition C104 is an AC stimulus with a frequency of 10 Hz.

[0139] From these tests, in the case of arbutin, better penetration effects were confirmed under test conditions C100 and C101 compared to test condition C1. It was also confirmed that better penetration effects were obtained with AC stimulation of 200 kHz or less than with negative DC stimulation as in test condition C102.

[0140] Figure 17E is a table showing the results of another test for the specific substance "phenylethyl resorcinol." Figure 17E shows the results of the same test as in Figure 16A above, but with the substance changed to phenylethyl resorcinol.

[0141] The output waveform according to test condition C110 is an AC stimulus with a frequency of 130 kHz, the output waveform according to test condition C111 is an AC stimulus with a frequency of 1 kHz, the output waveform according to test condition C112 is an AC stimulus with a frequency of 10 Hz, and the output waveform according to test condition C113 is an AC stimulus with a frequency of 40 kHz.

[0142] From these tests, it was confirmed that in the case of phenylethyl resorcinol, similarly to the case of arbutin, good penetration effects were obtained by AC stimulation of 200 kHz or less.

[0143] FIG. 17F is a table showing other test results for the specific object "hydrolyzed collagen." FIG. 17F shows the results of a test performed in the same manner as FIG. 16A above, but with the substance changed to hydrolyzed collagen. However, in this test, for 2-4 above, after the treatment of 2-3, the stratum corneum at the application site was peeled off with adhesive tape (a keratin checker commercially available under the product name "D-Squame (registered trademark)"), and the amount of hydrolyzed collagen contained in the stratum corneum layers 1-10 was quantified.

[0144] The solution pH was 6.3, the concentration was 10.0%, the usage time was 300 seconds, and the number of subjects was 2. The output waveform for test condition C90 was an AC stimulus with a frequency of 70 kHz, and the output waveform for test condition C91 was a combination with switching between an AC stimulus with a frequency of 30 kHz and an AC stimulus with a frequency of 70 kHz (i.e., alternating application).

[0145] From these tests, it was confirmed that the penetration effect is also observed for hydrolyzed collagen or substances having similar properties (e.g., polymeric compounds) even at frequencies other than the high frequency band.

[0146] Therefore, the control information associated with hydrolyzed collagen or a substance having similar properties (e.g., a polymer compound) may have the following characteristics. For example, the value of the second parameter (=α1) is preferably 30 kHz to 100 kHz, more preferably around 70 kHz, for output mode M1 shown in FIG. 7 (or the output modes related to the output waveforms in FIGS. 7A to 7C). It is also preferable to apply 30 to 100 kHz AC stimulation and DC stimulation within a predetermined period. It is also preferable to apply a combination of different frequency bands of 30 to 100 kHz within a predetermined period.

[0147] Figure 17G is a table showing the results of another test on the specific subject "collagen peptide." Figure 17G shows the results of the same test as in Figure 17F above, but with the substance changed to collagen peptide.

[0148] The output waveform related to the test condition C130 is an AC stimulus with a frequency of 1 MHz, the output waveform related to the test condition C131 is an AC stimulus with a frequency of 70 kHz, and the output waveform related to the test condition C132 is a combination with switching between AC stimuli of 3 MHz and AC stimuli of 70 kHz (i.e., alternate application). The output waveform related to the test condition C133 is an AC stimulus with a frequency of 70 kHz, and the output waveform related to the test condition C134 is a combination with switching between AC stimuli of 30 kHz and AC stimuli of 70 kHz (i.e., alternate application). The difference between the test condition C131 and the test condition C133 is that the former has a usage time of 90 seconds and N number of 3, while the latter has a usage time of 300 seconds and N number of 2. Note that the test conditions C130 to C132 have a usage time of 90 seconds and N number of 3, and the test condition C134 has a usage time of 300 seconds and N number of 2.

[0149] As shown in Figure 17G, for collagen peptide, it was found that only test condition C130, only AC stimulation of 100kHz or less (e.g., AC stimulation of 70kHz) such as test conditions C131 and C133, a combination of AC stimulation of 100kHz or less and high frequency (e.g., 3Mhz) such as test condition C132, and a combination of AC stimulation of 100kHz or less and another AC stimulation of 100kHz or less (e.g., 30kHz and 70kHz) such as test condition C134 were preferable compared to test condition C1. It was also found that AC stimulation of 100kHz or less and a combination of AC stimulation of high frequency (e.g., 3MHz) and AC stimulation of 100kHz or less were preferable.

[0150] In addition, the penetration effect can be expected for lipids and oil-soluble substances in frequencies other than the high frequency band. In this case, the value of the second parameter (=α1) is preferably 156 kHz or more for the output mode M1 shown in Figure 7 (or the output modes related to the output waveforms in Figures 7A to 7C). In this case, if there is a warming effect, there is a diffusing action, and the penetration effect is good.

[0151] Figure 17H ​​is a table showing the results of another test for the specific object "tocopherol acetate." Figure 17H ​​shows the results of the same test as in Figure 16A above, but changing the substance to tocopherol acetate.

[0152] The output waveform under test condition C120 is an AC stimulus with a frequency of 1 MHz, and the output waveform under test condition C121 is an AC stimulus with a frequency of 190 kHz.

[0153] From these tests, it was found that in the case of tocopherol acetate, AC stimulation of 190 kHz and AC stimulation of 1 MHz were more preferable than test condition C1.

[0154] FIG. 18 is an explanatory diagram of a control mode when a plurality of pieces of control information are used simultaneously. In the example shown in FIG. 18, the control information associated with the mode configuration information "M3+M4+M2" and the control information associated with the mode configuration information "M3+M2+M4" are used simultaneously. The mode configuration information "M3+M4+M2" represents that the output mode M3, the output mode M4, and the output mode M2 ​​are executed in this order (or in another order, the same applies below), and the mode configuration information "M3+M2+M4" represents that the output mode M3, the output mode M2, and the output mode M4 are executed in this order. In this case, as shown in FIG. 18, a process based on the control information associated with the mode configuration information "M3+M4+M2" (see section PT1 in FIG. 18) and a process associated with the mode configuration information "M3+M2+M4" (see section PT2 in FIG. 18) may be executed alternately and repeatedly.

[0155] In this way, even when using cosmetics or the like containing multiple active ingredients (target substances), control (processing) based on each piece of control information associated with multiple control information IDs can be repeatedly executed in an alternating manner.

[0156] In addition, when using cosmetics containing multiple active ingredients (subjects), the blending ratio between the multiple subjects may be reflected in the control. For example, in the example shown in Fig. 18, if the subject related to the control information associated with the mode configuration information "M3+M4+M2" has a significantly higher blending ratio than the subject related to the control information associated with the mode configuration information "M3+M2+M4", the process based on the control information associated with the mode configuration information "M3+M4+M2" may be executed preferentially (for example, in a manner in which the number of repetitions is increased or the reference execution time is lengthened) over the process associated with the mode configuration information "M3+M2+M4".

[0157] Although each embodiment has been described above in detail, the present invention is not limited to the specific embodiment, and various modifications and changes are possible within the scope of the claims. In addition, it is also possible to combine all or a plurality of the components of the above-described embodiments.

[0158] For example, in the above-described embodiment, the cosmetic device 4 can output control information corresponding to various objects by linking with the user terminal 2 and the information processing device 3, but is not limited thereto. For example, the cosmetic device 4 may be a dedicated device that operates based on control information corresponding to one or more specific objects. In this case, the cosmetic device 4 may be sold as a set with one or more specific objects. Alternatively, even if the cosmetic device 4 is capable of acquiring control information corresponding to various objects, the cosmetic device 4 may be set to operate based on control information corresponding to one or more specific objects as a default setting. In this case, the cosmetic device 4 may also be sold as a set with one or more specific objects.

[0159] In addition, in a modified example in which the beauty device 4 is a dedicated device that operates based on control information corresponding to one or more specific objects, the user terminal 2 and the information processing device 3 may be omitted as components of the information processing system 1 according to the above-mentioned embodiment.

[0160] Also, in the above-mentioned embodiment, one or more objects are associated with each of the various control information, but the type of control information may be only one. In this case, it is preferable that the one control information is used together with one or more specific objects, but it is not necessary that they are associated with each other. Similarly, in the above-mentioned embodiment, control information is associated with each of the various objects, but the type of object may be only one. In this case, it is preferable that the object is used together with dedicated control information, but it is not necessary that they are associated with each other.

[0161] Furthermore, in the above-described embodiment, one piece of control information is associated with one object, but a plurality of pieces of control information may be associated with one object.

[0162] In the above-described embodiment, the lower-level data 512 (see FIG. 5) forming the control information includes the values ​​of the first to third parameters, but some of the values ​​of the first to third parameters may be omitted. The fourth parameter may include a parameter that specifies a change pattern of the pair of electrodes that generate the output waveform. Such a fourth parameter is suitable for an electrode configuration in which multiple electrodes 40 are arranged in a variety of ways. The fifth parameter may include a parameter that specifies whether the output waveform is an attenuated waveform or not.

[0163] In the above-described embodiment, the control information may be set for each model or type of cosmetic device 4. In this case, the control information can be adapted to the characteristics of various cosmetic devices 4.

[0164] In the above-described embodiment, the control information associated with an object may be set based on at least one of various characteristics or properties of the object, such as (1) a property related to the solubility of the object in a solvent, (2) a property related to charging, and (3) a molecular weight or an attribute thereof, but is not limited thereto. For example, the control information associated with an object may be set in consideration of the "pH value", "base", "mixing ratio", "effectiveness", etc. of the entire cosmetic product in addition to at least one of these.

[0165] In the above embodiment, the process performed by the cosmetic device 4 based on the control information is based on an electrical output waveform, but is not limited thereto. For example, instead of or in addition to the electrical output waveform, any one or more of a method using heat from a heater or the like, a method using light such as LED (Light Emitting Diode) light or IPL (Intense Pulsed Light), a method using ultrasonic waves, a magnetic method, a method using electromagnetic waves, and a method using plasma may be used. In this case, a process that does not use the electrode 40 may be realized.

[0166] In the above-described embodiment, the control information associated with one object may be corrected based on information about the user who uses the object. For example, the control information may be corrected based on the user's attributes (e.g., gender, age, race, etc.), the user's concerns, questionnaire information such as skin type, the usage status of the beauty device 4, etc.

[0167] In the above-described embodiment, the control information associated with one object may be corrected according to the external environment at the time of use (e.g., the strength of ultraviolet rays, humidity, etc.) This is because the most effective control information may differ depending on the external environment at the time of use.

[0168] In addition, in the above-described embodiment, the control information associated with one object may be set for each type of beauty device 4. In this case, the information processing device 3 may extract the control information according to the type of beauty device 4 owned by the user who has requested the control information.

[0169] In the above-mentioned embodiment, the control information associated with one object is adapted mainly so that the object can effectively penetrate into the human skin, but is not limited thereto. For example, it has been found that in electrotherapy, there are objects that are likely to have the effect of electricity itself in addition to penetration. That is, in addition to penetration, the skin may be activated by the action of electricity alone, resulting in firmness and elasticity of the skin, and there are objects that are suitable for use in such cases. In addition, LEDs and electromagnetic waves have more significant effects on cell activation, blood circulation promotion, sterilization, etc. than the effect of promoting the penetration of the object, and there are objects that are suitable for use in such cases. Specifically, objects containing citric acid may be more easily conductive to electricity, and a smooth solvent may transmit heat faster than a gel-like object, and the bodily sensation and transmission of electrical stimulation may change depending on the properties of the object. Therefore, for objects that are not intended to penetrate, control information other than the method of penetration into the human skin may be associated with them, taking into account their properties and texture. In this case, for example, control information for realizing electrical stimulation processing (e.g., an output waveform for high-frequency electrical muscle stimulation) may be associated with an object through which electricity flows easily, and control information for realizing a heating processing method (e.g., an output waveform for heating by radio waves) may be associated with an object that contains components through which heat is easily transmitted (including components that serve as a base).
