Description

Method for using and configuring a skin beauty device using ultrasonic cross-frequency and electrical stimulation

[0001] The present invention relates to a method for using and configuring a skin beauty device using ultrasonic cross-frequency and electrical stimulation, and more particularly, to a method for using and configuring a skin beauty device capable of measuring the skin impedance of a subject and analyzing the skin condition of the subject based on the skin impedance of the subject, and transmitting and irradiating the skin of the subject with appropriate current, light, and ultrasonic cross-frequency according to the analyzed skin condition of the subject to provide electrical stimulation, optical stimulation, and ultrasonic stimulation.

[0002] As interest in appearance grows among people of all ages, functional cosmetics are increasingly preferred to maintain healthy and beautiful skin. Furthermore, many people are turning to professional skin care salons for regular skincare. However, due to the financial burden and time constraints associated with salon visits, demand for home skincare, where individuals manage their skin at home, is on the rise. However, most home skincare involves users rubbing skin care devices onto the desired area. However, since most users do not have professional skin care knowledge, excessive skin irritation frequently occurs, which can have negative effects on the skin.

[0003] Furthermore, existing skin care devices utilize vibration, ultrasound, or iontophoresis, or a combination of these methods, to improve the skin condition of the recipient. While these devices are simple in function and operation, they require training in how to use them. Furthermore, the treatment time varies depending on the recipient's skin condition and characteristics, limiting their ability to provide customized results.

[0044] Beauty device

[0045] Hereinafter, the configuration of a preferred embodiment of a skin beauty device (100) using ultrasonic cross-frequency and electrical stimulation according to the present invention will be described in detail with reference to the attached drawings.

[0046] FIG. 1 and FIG. 2 are images illustrating a skin beauty device using ultrasonic cross-frequency and electrical stimulation according to one embodiment of the present invention, FIG. 3 is a block diagram illustrating components built into an electrical stimulation and optical output head according to one embodiment of the present invention, and FIG. 4 is a block diagram illustrating components built into an ultrasonic output head according to one embodiment of the present invention.

[0047] Referring to FIGS. 1 and 2, a skin beauty device (100) using ultrasonic cross-frequency and electrical stimulation according to one embodiment of the present invention can improve the skin condition of a subject based on a combination of electrical stimulation, optical stimulation, and ultrasonic stimulation by transmitting and irradiating current, light, and ultrasonic cross-frequency to the skin of a subject, and for this purpose, includes a main body (110), a current and light output head (120), and an ultrasonic output head (130).

[0048] In one embodiment, the main body (110) is a part that a user, a subject, holds while performing a skin treatment (home skin care), and includes a power button (111), an impedance measurement button (112), a mode window (113), a level selection button (114), and a switch (115).

[0049] In one embodiment, the power button (111) may be a button operated by the subject to turn on the power of the beauty device (100) for starting a skin treatment or turn off the power of the beauty device (100) for ending a skin treatment.

[0050] In one embodiment, the beauty device (100) is preferably equipped with a power supply device (battery) so that the power can be turned on or off according to the operation of the power button (111), although not shown in the drawing.

[0051] In one embodiment, the impedance measurement button (112) may be a button operated by the subject to measure skin impedance required for analyzing the skin condition of the subject while the beauty device (100) is operating in the first mode.

[0052] At this time, the beauty device (100) can measure the skin impedance of the subject based on the current and light output head (120).

[0053] In one embodiment, the mode window (113) may be a display that displays detailed modes of the first mode and the second mode operable in the beauty device (100) in the form of text.

[0054] Here, the first mode refers to an operation mode of the beauty device (100) for transmitting and irradiating current and light to the skin of the subject from the current and light output head (120), and the second mode refers to an operation mode of the beauty device (100) for irradiating ultrasonic waves of a cross frequency to the skin of the subject from the ultrasonic output head (130).

[0055] In addition, the first mode can be automatically paused when the current and light output head (120) does not come into contact with the skin of the subject, and the second mode can be automatically paused when there is no movement of the ultrasound output head (130) by the beauty device (100) for a preset period of time (e.g., 5 seconds).

[0056] At this time, the detailed modes of the first mode (e.g., CL, GO, LN, LF) and the detailed modes of the second mode (e.g., RN, GU, WK, EY) displayed in the mode window (113) may be plural as shown in FIGS. 1 and 2.

[0057] Additionally, although not shown in the drawing, the mode window (113) may have a built-in backlight to match the detailed mode text of the first mode and the detailed mode text of the second mode, respectively.

[0058] Accordingly, the mode window (113) can emit light from a backlight that matches at least one of the plurality of detailed modes while the beauty device (100) is operated in the first mode or the second mode.

[0059] Meanwhile, the user can visually check the operation mode of the beauty device (100) in real time through the light emitted from the backlight of the mode window (113).

[0060] In one embodiment, the level selection button (114) may be a button operated by the subject of the treatment to irradiate the subject's skin with ultrasound of a preset intensity for each detailed mode of the second mode from the ultrasound output head (130) when the beauty device (100) is operated in the second mode for irradiating ultrasound of a cross-frequency.

[0061] At this time, the mode window (113) can display the intensity of the ultrasound selected through the operation of the level selection button (114) based on the light generated from the backlight while the beauty device (100) is operating in the second mode.

[0062] In one embodiment, the switch (115) may be a button operated by the subject to cause the beauty device (100) to operate in at least one of a first mode and a second mode.

[0063] That is, when the beauty device (100) is set to operate in the first mode via the switch (115), the current and light output head (120) can be operated, and conversely, when the beauty device (100) is set to operate in the second mode via the switch (115), the ultrasonic output head (130) can be operated.

[0064] In one embodiment, the current and light output head (120) is a device coupled to the body (110) so as to face the ultrasonic output head (130) as shown in FIGS. 1 and 2.

[0065] Referring to FIG. 3, the current and light output head (120) includes an output electrode (121), an input electrode (122), an LED (123), a skin condition analysis unit (124), a current control unit (125), and a light control unit (126) to measure the skin impedance of the subject and analyze the skin condition of the subject, and to transmit and irradiate an appropriate current and light to the subject's skin to care for the subject's skin according to the analyzed skin condition of the subject.

[0066] In one embodiment, the output electrode (121) is an electrode built into the current and light output head (120) that can pass current through the skin of the subject to measure the skin impedance of the subject.

[0067]

[0068] *In one embodiment, the input electrode (122) is an electrode built into the current and light output head (120), similar to the output electrode (121), and can measure the voltage generated according to the resistance (impedance) to the flow of current output from the output electrode (121).

[0069] In one embodiment, the LED (123) is positioned on the outer surface of the current and light output head (120) and can generate light of a preset wavelength and irradiate it onto the skin of the subject to provide a light stimulus to the skin of the subject to improve the skin condition of the subject analyzed based on the skin impedance of the subject.

[0070] At this time, the color of the light of a preset wavelength generated for optical stimulation from the LED (123) is not limited, but in one embodiment, it may be red (620 to 700 nm), green (525 to 550 nm), blue (450 to 495 nm), or purple (400 to 420 nm).

[0071] In addition, light of a preset wavelength that can be generated from the LED (123) can be irradiated onto the skin of the subject, thereby providing LED therapy to the subject.

[0072] As a specific example, the red wavelength light generated from the LED (123) may be light for providing LED therapy to the patient according to Anti-aging Care, the green wavelength light may be light for providing Rejuvenating Care, the blue wavelength light may be light for providing Calming Care, and the purple wavelength light may be light for providing Brightening Care.

[0073] And the LED (123) can stop the process of providing light stimulation to the skin of the subject by pausing when the current and light output head (120) is not in contact with the skin of the subject.

[0074] In one embodiment, the skin condition analysis unit (124) is built into the current and light output head (120), and when the skin impedance measurement of the subject is requested through the operation of the impedance measurement button (122) while the beauty device (100) is operated in the first mode through the switch (115), the skin impedance of the subject can be calculated in real time in conjunction with the output electrode (121) and the input electrode (122).

[0075] As a specific example, the skin condition analysis unit (124) can calculate the skin impedance of the subject using Ohm's law based on the following [Mathematical Formula 1].

[0076]

[0077] In the above [Mathematical Formula 1], Z represents skin impedance, I represents current output from the output electrode (121), and V represents voltage measured from the input electrode (122).

[0078] This skin condition analysis unit (124) analyzes the skin condition of the subject based on the skin impedance of the subject, generates information about the skin condition of the subject, and can transmit the information about the skin condition of the subject to the current control unit (125) and the light control unit (126), respectively.

[0079] At this time, information on the skin condition of the subject may include the results of analyzing whether the subject's skin is dry and the thickness of the skin layers such as the epidermis, dermis, and subcutaneous fat layer based on the skin impedance of the subject calculated by the skin condition analysis unit (124).

[0080] In one embodiment, the current control unit (125) is built into the current and light output head (120) and can control the value of the current to be delivered from the output electrode (121) to the skin of the subject based on information about the skin condition of the subject so as to deliver a current appropriate for skin care of the subject to the skin of the subject.

[0081] At this time, the output electrode (121) can provide electrical stimulation to the skin of the subject based on the current controlled through the current control unit (125).

[0082] That is, the output electrode (121) may be provided in the current and light output head (120) to not only pass current through the skin of the subject to measure the skin impedance of the subject, but also to provide electrical stimulation to the surface layer of the skin of the subject.

[0083] This means that the current and light output head (120) of the present invention is a component that simultaneously measures the impedance of the subject and provides stimulation for skin care.

[0084] In addition, the current and light output head (120) of the present invention can simultaneously provide electrical stimulation and light stimulation to the skin of the subject.

[0085] In one embodiment, the output electrode (121) can stop the process of electrically stimulating the skin of the subject by pausing when the current and light output head (120) is not in contact with the skin of the subject.

[0086] And the electrical stimulation of the output electrode (121) may be a non-invasive stimulation method based on at least one current transmission method among Electriporation, Micro-current, EMS, and Galvanic.

[0087] Here, Electriporation is an electrical stimulation that creates electrical holes in the cell membrane to promote the penetration of substances into the cells, Micro-current is an electrical stimulation that stimulates the skin and muscles with a very low current of 1㎂ to 1㎃ to promote cell regeneration, muscle tone improvement, and collagen production, EMS (Electrical Muscle Stimulation) is an electrical stimulation that stimulates and contracts muscles to strengthen and rehabilitate muscles, Galvanic is an electrical stimulation that improves the condition of the skin by penetrating ionized substances into the skin with a direct current (DC) current, and Electriporation and Galvanic are also capable of removing waste products and caring for pores.

[0088] That is, the electrical stimulation of the output electrode (121) may be a non-invasive stimulation method that delivers current to the skin of the subject to stimulate the pores, cells, and muscles of the subject.

[0089] In one embodiment, the light control unit (126) is built into the current and light output head (120), and can control the wavelength of light to be irradiated from the LED (123) to the skin of the subject based on information about the skin condition of the subject, so as to irradiate light of a wavelength appropriate for skin care of the subject's skin to the surface layer of the subject's skin from the LED (123) provided in the current and light output head (120).

[0090] At this time, the LED (123) can provide light stimulation based on light of a wavelength controlled through a light control unit (126) to the skin of the subject.

[0091] In addition, the light stimulation of the LED (123) may be a non-invasive stimulation method for providing the subject with at least one LED therapy effect among Anti-aging Care, Rejuvenating Care, Calming Care, and Brightening Care by irradiating light of a specific wavelength to the skin surface layer of the subject.

[0092] In one embodiment, the ultrasonic output head (130) is a device coupled to the body (110) so as to face the current and light output head (120) as shown in FIGS. 1 and 2.

[0093] Referring to FIG. 4, the ultrasonic output head (130) includes an analog-to-digital conversion unit (131), a skin condition determination unit (132), an ultrasonic cross-frequency combination unit (133), a waveform generation unit (134), an amplifier unit (135), an impedance matching circuit (136), and an ultrasonic vibrator (137) to analyze the skin condition of the subject based on the skin impedance of the subject measured by the skin condition analysis unit (124) and to irradiate the subject with an ultrasonic wave of a cross-frequency appropriate for caring for the subject's skin according to the analyzed skin condition of the subject.

[0094] In one embodiment, the analog-to-digital conversion unit (131) is built into the ultrasound output head (130) and can receive the skin impedance of the subject, which is an analog signal, from the skin condition analysis unit (124) and then convert it into a digital signal.

[0095] In one embodiment, the skin condition determination unit (132) is built into the ultrasonic output head (130) and can determine (analyze) the skin condition of the subject based on the skin impedance of the subject converted into a digital signal by the analog-to-digital conversion unit (131) to generate information on the skin condition of the subject.

[0096] At this time, the information on the skin condition of the subject generated by the skin condition judgment unit (132) may include the results of analyzing the skin impedance of the subject, such as whether the subject's skin is dry, and the thickness of the skin layers such as the epidermis, dermis, and subcutaneous fat layer, based on the skin impedance of the subject, in the same manner as the skin condition analysis unit (124).

[0097] In one embodiment, the ultrasonic cross-frequency combination unit (133) is built into the ultrasonic output head (130), and can combine the cross-order and time of cross-frequencies appropriate for caring for the skin of the subject according to the skin condition of the subject based on information about the skin condition of the subject generated by the skin condition determination unit (132).

[0098] At this time, cross-frequency refers to a combination of high-frequency ultrasound to stimulate the surface layer of the skin of the subject and low-frequency ultrasound to stimulate the deep tissue of the skin.

[0099] Additionally, the cross-order of the cross-frequency means the order in which high-frequency ultrasound and low-frequency ultrasound are irradiated to the skin of the subject simultaneously or sequentially.

[0100] And the time of the cross-frequency refers to the irradiation time of high-frequency ultrasound and low-frequency ultrasound to be irradiated to the skin of the subject, which may be the same as the operation time of the beauty device (100) in the second mode.

[0101] In one embodiment, the waveform generation unit (134) is built into the ultrasonic output head (130) and can generate a waveform of the cross-frequency combined in the ultrasonic cross-frequency combination unit (133).

[0102] In one embodiment, the amplifier (135) is built into the ultrasonic output head (130) and can amplify the waveform of the cross frequency generated by the waveform generator (134).

[0103] In one embodiment, the impedance matching circuit (136) is built into the ultrasonic output head (130) and can match the impedance with the ultrasonic vibrator (137) so that ultrasonic waves of a cross frequency according to the waveform amplified by the amplifier (135) are irradiated from the ultrasonic vibrator (137) to the skin of the subject.

[0104] In one embodiment, the ultrasonic vibrator (137) forms the outer surface of the ultrasonic output head (130) and is a transducer (TD) that converts the waveform of the amplified cross-frequency ultrasonic waves into physical ultrasonic waves, converts the electrical signal into mechanical vibrations to generate high-frequency ultrasonic waves and low-frequency ultrasonic waves, and then provides ultrasonic stimulation to the skin of the subject through the cross-frequency ultrasonic waves.

[0105] At this time, the ultrasonic stimulation of the ultrasonic vibrator (137) may be a non-invasive stimulation method that irradiates the skin of the subject with a cross frequency that combines high-frequency ultrasound and low-frequency ultrasound in a cross order and time combined in the ultrasonic cross frequency combination unit (133) to improve the skin condition of the subject.

[0106] In addition, the ultrasonic stimulation of the ultrasonic vibrator (137) can irradiate the skin of the subject with cross-ultrasonic waves of a frequency appropriate for caring for the skin of the subject according to whether the skin is dry and the thickness of the skin layer included in the information on the skin condition of the subject generated by the skin condition judgment unit (132).

[0107] As a specific example, when the skin condition of the subject is analyzed by the skin condition determination unit (132) to be in a dry state and thus in need of skin layer care, the ultrasonic stimulation of the ultrasonic vibrator (137) may irradiate the skin of the subject in a predetermined high-frequency ultrasound appropriate for skin layer care in an alternating order and at a predetermined time according to whether the skin is dry and the thickness of the skin layer included in the information on the skin condition of the subject generated by the skin condition determination unit (132), or when the skin layer is thick, low-frequency ultrasound may be irradiated to the skin of the subject.

[0108] At this time, the preset frequency value of the high-frequency ultrasound that the ultrasonic vibrator (137) irradiates onto the skin of the subject may be 1 to 23 MHz (preferably 1 to 3, 10, 17 to 19, 23 MHz) applicable as the frequency value of the high-frequency ultrasound.

[0109] In addition, the ultrasonic vibrator (137) can irradiate high-frequency ultrasound of a preset frequency value to the skin of the subject by repeating a cycle of irradiating (Burst on) and stopping (Burst off) high-frequency ultrasound to the skin of the subject.

[0110] Here, the time sum per set of high-frequency ultrasonic irradiation (Burst on) and irradiation stop (Burst off) of the ultrasonic vibrator (137) can be set to 30 ms (0.03 seconds).

[0111] And the ultrasonic vibrator (137) can change the level of high-frequency ultrasonic irradiation intensity from 1 to 3 by operating the level selection button (114). When the level of high-frequency ultrasonic irradiation intensity is set to 1, the ratio of high-frequency ultrasonic irradiation (Burst on) and irradiation stop (Burst off) per cycle can be set to 10:120. When the level of high-frequency ultrasonic irradiation intensity is set to 2, the ratio of high-frequency ultrasonic irradiation (Burst on) and irradiation stop (Burst off) per cycle can be set to 15:120. When the level of high-frequency ultrasonic irradiation intensity is set to 3, the ratio of high-frequency ultrasonic irradiation (Burst on) and irradiation stop (Burst off) per cycle can be set to 30:120.

[0112] That is, as the level of high-frequency ultrasonic irradiation intensity increases, the time of high-frequency ultrasonic irradiation (Burst on) of the ultrasonic vibrator (137) can increase.

[0113] These ultrasonic vibrators (137) can automatically pause when there is no movement of the ultrasonic output head (130) of the beauty device (100) for a preset period of time (e.g., 5 seconds), thereby stopping the process of providing ultrasonic stimulation to the skin of the subject.

[0114] Meanwhile, the beauty device (100) of the present invention can provide skin care to a subject in various forms by combining electrical stimulation from the current and light output head (120) and ultrasonic stimulation from the ultrasonic output head (130).

[0115] As a specific example, the beauty device (100) discharges skin waste from a subject through galvanic-based electrical stimulation (hereinafter, “first electrical stimulation”) from a current and light output head (120), and then irradiates the subject’s skin with cross-frequency ultrasound from an ultrasonic output head (130) to remove dead skin cells, thereby improving the texture of the subject’s epidermis.

[0116] At this time, the first electrical stimulation mode (120a) for generating the first electrical stimulation from the current and light output head (120) may be an electrical stimulation mode that transmits a bipolar pulse (+ Pulse) to the skin of the subject to discharge waste products, as shown in FIG. 5, and transmits a negative pulse (- Pulse) to the skin of the subject while the bipolar pulse is transmitted to the skin of the subject to provide electrical stimulation so that the subject can recognize the intensity of the first electrical stimulation.

[0117] As another specific example, the beauty device (100) stimulates and contracts the muscles of the subject through EMS-based electrical stimulation (hereinafter, 'second electrical stimulation') from the current and light output head (120) to strengthen them, and then irradiates ultrasound of a cross-frequency from the ultrasound output head (130) to the skin of the subject to promote the production of collagen in the skin of the subject, thereby improving skin wrinkles and facial contours of the subject.

[0118] At this time, the second electrical stimulation mode (120b) for generating the second electrical stimulation from the current and light output head (120) may be an electrical stimulation mode that transmits a burst signal to the skin of the subject for contraction / relaxation of pores on the surface of the skin of the subject based on a method in which high-voltage positive (+) and negative (-) pulses are generated at regular intervals, as shown in FIG. 6, thereby providing electrical stimulation, thereby allowing good ingredients to be put into the skin of the subject when the pores are relaxed.

[0119] As another specific example, the beauty device (100) promotes cell regeneration by increasing ATP (Adenosine Triphosphate) of the subject through microcurrent-based electrical stimulation (hereinafter, 'third electrical stimulation') from the current and light output head (120), and then irradiates ultrasound of a cross-frequency from the ultrasound output head (130) to the subject's skin to promote cell regeneration and recovery by decreasing MMPs (Matrix Metalloproteinases), which are enzymes that decompose structural proteins of the skin such as collagen, and increasing HSPs (Heat Shock Proteins), which are proteins that alleviate the stress response of cells, thereby regenerating the subject's skin.

[0120] At this time, the role of MMPs is as an enzyme that breaks down extracellular matrix (ECM) components such as collagen, and plays an important role in tissue restructuring, wound healing, and inflammatory responses. It can be expressed through thermal stimulation by ultrasound to break down old collagen and promote the production of new collagen, thereby promoting skin regeneration and recovery.

[0121] In addition, HSPs play an important role in the cellular stress response, being involved in protein folding, cell protection, and damage repair. They are expressed through thermal stimulation by ultrasound to strengthen the cellular stress response, promoting the repair and regeneration of damaged proteins, and promoting the survival of skin cells, thereby improving skin health and promoting collagen synthesis to maintain skin elasticity and structure.

[0122] And the third electrical stimulation mode (120c) for generating the third electrical stimulation in the current and light output head (120) may be an electrical stimulation mode that applies a burst signal that applies a current limiting signal to consecutive positive and negative pulses (+ Pulse and - Pulse) to the skin of the subject, as shown in FIG. 7, thereby providing the same electrical stimulation as the microcurrent of the living body to the skin of the subject.

[0123] As an additional example, the beauty device (100) absorbs the pore relaxation / contraction component of the skin of the recipient through electriporation-based electrical stimulation (hereinafter, “fourth electrical stimulation”) from the current and light output head (120), and then irradiates the skin of the recipient with cross-frequency ultrasound from the ultrasound output head (130) to deliver nutritional components for skin improvement to the dermis layer, thereby maximizing the penetration of nutritional components into the skin of the recipient.

[0124] At this time, the fourth electrical stimulation mode (120d) for generating the fourth electrical stimulation from the current and light output head (120) may be an electrical stimulation mode that provides electrical stimulation by transmitting a pulse in the form of an envelope of a low frequency that can reach deep skin tissue to the skin of the subject, as shown in FIG. 8.

[0125] Meanwhile, it is desirable to understand that the first to fourth electrical stimulation modes that can be provided by the current and light output head (120) can be implemented by the output electrode (121) of the current and light output head (120).

[0126] The skin of the subject to be treated with electrical stimulation, optical stimulation, or ultrasonic stimulation from the beauty device (100) of the present invention is preferably the facial skin of the subject to be treated with, but is not limited thereto, and may be the skin of another body part to which electrical stimulation, optical stimulation, or ultrasonic stimulation can be applied.

[0127]

[0128] Beauty method

[0129] Hereinafter, with reference to the attached drawings, a preferred process of a method of using and configuring a skin beauty device (S100) using ultrasonic cross-frequency and electrical stimulation performed by the beauty device (100) of the present invention will be described in detail.

[0130] FIG. 9 is a flowchart illustrating a process of using and configuring a skin beauty device using ultrasonic cross-frequency and electrical stimulation according to one embodiment of the present invention.

[0131] First, the user, who is the subject of the treatment, can turn on the power of the beauty device (100) from the OFF state by operating the power button (111) provided on the main body (110) for home skin care of the skin (facial skin) using the beauty device (100) (S110).

[0132] After that, the subject of the treatment sets the beauty device (100) to operate in the first mode by operating the switch (115) provided in the main body (110), and when the subject of the treatment requests measurement of skin impedance by operating the impedance measurement button (112), the current and light output head (120) can analyze the subject of the treatment's skin condition based on the measurement of the subject's skin impedance and the skin impedance (S120).

[0133] Thereafter, when the subject of the treatment does not operate the switch (115) and the operation mode remains in the first mode, the beauty device (100) can provide electrical stimulation and optical stimulation appropriate for caring for the skin of the subject of the treatment through the current and light output head (120), and when the subject of the treatment maintains the beauty device (100) in the second mode through the switch (115), the beauty device (100) can provide ultrasonic stimulation appropriate for caring for the skin of the subject of the treatment through the ultrasonic output head (130) (S130).

[0134] At this time, in the skin beauty progress step (S130), the current and light output head (120) can be operated in at least one of the first to fourth electrical stimulation modes to provide electrical stimulation to the skin of the subject.

[0135] In addition, in the above skin beauty treatment step (S130), the ultrasonic output head (130) can provide ultrasonic stimulation to the skin of the subject based on repeating a cycle of irradiating (Burst on) and stopping (Burst off) high-frequency ultrasonic waves having a frequency value of at least one of 3, 10, 17, and 23 MHz.

[0136] After that, the beauty device (100) may operate in a pause mode when a preset event occurs while operating in the first mode or the second mode, thereby stopping the process of stimulating the skin of the subject (S140).

[0137] At this time, the preset event may be a case where the current and light output head (120) is separated from the skin of the subject when the beauty device (100) is operated in a first mode for providing electrical stimulation and light stimulation to the skin of the subject, and a case where the ultrasonic output head (130) of the beauty device (100) does not move for a preset period of time (e.g., 5 seconds) when the beauty device (100) is operated in a second mode for providing ultrasonic stimulation to the skin of the subject.

[0138] At this time, if the beauty device (100) is operating in pause mode (S140-YES), the beauty device (100) can be automatically turned off (S150) if the pause mode is maintained for a preset time (e.g., 1 minute).

[0139] In contrast, if the beauty device (100) operates in the first or second mode for skin care (S140-NO), the beauty device (100) completes skin care when the time set for each mode has elapsed (S160) and can be switched to standby mode.

[0140] At this time, the operating time of the first mode may be the time of electrical stimulation and light stimulation included in the information on the skin condition of the subject analyzed by calculating the skin impedance of the subject by the skin condition analysis unit (124).

[0141] Additionally, the operating time of the second mode may be a time combined with the crossover order in the ultrasonic crossover frequency combination unit (133).

[0142] After that, the beauty device (100) switched to standby mode can perform skin beauty treatment again or be turned off (S170) depending on whether a preset event occurs.

[0143] At this time, if the beauty device (100) switches to standby mode and the subject inputs a signal by briefly pressing the power button (111) for less than a preset time (e.g., 1 to 3 seconds) (S170-YES), the beauty device (100) can proceed with skin beauty treatment again (S130).

[0144] In contrast, if the subject of the treatment does not operate the beauty device (100) for a preset period of time (e.g., 1 minute) after the beauty device (100) has been switched to standby mode (S170-NO_1), the beauty device (100) may be turned off.

[0145] In addition, if the subject of the treatment inputs a signal by pressing the power button (111) for a preset time (e.g., 3 seconds) or longer after the beauty device (100) has been switched to standby mode (S170-NO_2), the beauty device (100) may be turned off.

While the above description has been made with reference to preferred embodiments of the present invention, those skilled in the art will appreciate that various modifications and variations can be made to the present invention without departing from the scope of the present invention.
