In certain embodiments, the user device 190 may communicate directly with the practitioner system 200, for example via a computer network (for example, the computer network 300).

[0196] The user device 190 is entirely optional. In alternative embodiments, the skin treatment system 100 does not comprise a user device 190. Instead, the skin treatment device 110 may itself perform the functions of the user device 190. For example, the skin treatment device 110 may be configured to be connected to the computer network 300, for example, via an internet connection. In this manner, as would be understood by those skilled in the art, the skin treatment device 110 itself may communicate with the server 400 via the computer network 300. In this embodiment, this connection from the skin treatment device 110 allows for the above-noted functionality of the skin treatment system 100 being able to communicate with the server 400 via the computer network 300. In certain embodiments, for example in which the skin treatment system 100 can communicate directly with the practitioner system 200, the skin treatment device 110 itself can communicate with the practitioner system 200, and in such embodiments, the connection from the skin treatment device 110 allows for the above-noted functionality of the skin treatment system 100 being able to communicate with the practitioner system 200 via the computer network 300. The skin treatment device 110 may comprise a user interface which allows the patient / user to interact with the skin treatment device 110. As would be understood by those skilled in the art, the user interface may comprise a screen, touch input, keyboard, mouse, and / or speakers. It is to be understood herein for the purposes of the present description any reference to a user interface is to be considered as including within its scope any one or both of a user interface of the user device 190 and a user interface of the skin treatment device 110, unless specifically mentioned. For instance, in certain embodiments, for example in which the skin treatment system 100 does not include a user device, and some or all of the functionalities of the user device can be performed by the skin treatment device itself, the user interface of the skin treatment device can be configured to perform some or all of the functionalities of the user interface of the user device as described herein.

[0197] The above configurations of the treatment system 10 allows for improved functionality over existing treatment systems. The particular form of data (and the representations thereof) will be described in detail below.

[0198] A potential advantage of a system for example as described herein, in which the handheld treatment device communicates, at least indirectly, with a practitioner system, may include assisting the practitioner in determining whether an in-home treatment was carried out correctly. Another potential advantage is that the practitioner can select or adjust a treatment plan and transfer that plan to the hand-held treatment device.

[0199] Firstly, reference is made to Figs. 2 and 3, which will be used to describe the data that may be measured by the skin treatment device 110 and the general operating principles of the skin treatment device 110. The skin treatment device 110 is merely one form of a skin treatment device suitable for use with the treatment system 10. Accordingly, other skin treatment devices may instead be used with the treatment system 10. Generally, systems and / or methods described herein can be implemented with any energy-emitting, home-use skin treatment device which is placed in contact with the skin for carrying out the treatment.

[0200] The skin treatment device 110 comprises a housing 111. Housing 111 may be configured with an ergonomic shape so as to enable skin treatment device 110 to be held in a single hand by a user, and accordingly can be a handheld device. It is to be understood herein that the skin treatment device being a handheld device is intended to cover within its scope that the skin treatment device is a home-use device for performing a skin treatment locally at home by a user. The shape of housing 111 may be configured so as to enable holding and movement of the skin treatment device 110 across the skin to be treated.

[0201] In the embodiment shown in Figs. 2 and 3, massaging arms 112 extend from an end of skin treatment device 110 that is configured to be placed against the skin to be treated. However, the massaging arms 112 are entirely optional, and in alternative embodiments the skin treatment device 110 does not comprise any massaging arms. In the embodiment of Figs. 2 and 3, massaging arms 112 are configured to move. Thus, when placed against skin, the motion of massaging arms 112 may result in a massaging of skin between massaging arms 112. In alternative embodiments, the massaging arms can be stationary.

[0202] A material for an outer surface of each massaging arm 112 may be selected so as to avoid irritation or chafing of the skin. Prior to or during use, a lubricating fluid, gel, or cream may be applied to each massaging arm 112 and / or to the skin of the user. The lubricating fluid, gel, or cream may be electrically conducting.

[0203] Flexible sleeve 113 of the skin treatment device 110 may be made of a flexible material, such as flexible plastic or rubber. The flexibility of flexible sleeve 113 may enable housing 111 to remain sealed while enabling motion of massaging arms 112.

[0204] Part or all of an outer surface of each massaging arm 112 may include, or may be made of, a conducting material. For example, the conducting material may include a metal, a conducting plastic, or another conducting material suitable for inclusion in an outer surface of massaging arm 112. The conducting material acts as an electrode which may facilitate electrical coupling of the massaging arm 112 to the skin to be treated. Accordingly, the skin treatment device 110 comprises two electrodes configured to come into electrically conductive contact with the skin of the user when the housing 111 is moved across a treatment area of the skin, for example when the user performs a treatment or a part (treatment session) thereof on the skin.

[0205] Skin treatment device 110 may include a user interface 114. The user interface 114 may include one or more controls. For example, controls may include one or more pushbuttons (as shown), switches, levers, dial wheels, or knobs. A user may operate a control so as to control operation of skin treatment device 110. For example, operation of a control may cause skin treatment device 110 to be powered on or off, enable connection (e.g. Bluetooth® connection) with the user device 190, set a treatment power, or to enter a standby status. Operation of user interface 114 may indicate selection of a mode of operation of skin treatment device 110.

[0206] User interface 114 may include one or more indicators 116. For example, an indicator 116 may include a light- emitting or other visible indication of a status of skin treatment device 110, such as whether it is powered on / off and / or whether it has a connection to the user device 190 (e.g. whether it has a Bluetooth® connection with the user device 190). In certain embodiments, for example in which the skin treatment system does not include the user device, the user interface 114 can include a display (for example, a screen) on which data or representations thereof (as described in further detail below) can be displayed to the user. In such examples, some or all of the functionalities of the user interface of the user device described herein can be performed by the user interface 114 of the skin treatment device.

[0207] Skin treatment device 110 may include one or more connectors 118. A connector 118 may be configured to connect to a corresponding connector of an appropriate cable. For example, a connector 118 may be configured to enable connection of skin treatment device 110 to an external power source (e.g. electric mains or power grid, or a power adapter, converter, or transformer) via an appropriate power cable. Additionally / alternatively, the connector 118 may connect to the user device 190, forming a wired connection thereto (e. g. alternatively to any wireless connection between the skin treatment device 110 and the user device 190).

[0208] In certain embodiments, the skin treatment device 110 may comprise a cell / battery. The skin treatment device 110 may be powered by the cell / battery. The cell / battery may optionally be rechargeable using the connector 118.

[0209] Fig- 3 is a block diagram of an electrical system 120 of the skin treatment device 110 in accordance with embodiments of the present disclosure.

[0210] Electrical system 120 may include a controller 140 for controlling operation of skin treatment device 110. Controller 140 may represent a unit, or a plurality of intercommunicating units, that is configured to coordinate among various components of electrical system 120. Controller 140 may include one or more processors that are configured to operate in accordance with programmed instructions. In another example, controller 140 may include circuitry (e.g. in the form of an integrated control circuit) that is configured to operate components of skin treatment device 110.

[0211] Controller 140 may communicate with a data storage unit 142. Data storage unit 142 may include one or more volatile or non-volatile data storage devices, or may represent a data storage function of a device. For example, data storage unit 142 may include a nonvolatile data storage device for storing programmed instructions or data for operation of the skin treatment device 110 in accordance with some embodiments of the present disclosure. Data storage unit 142 may be used to store data that is generated during operation of the skin treatment device 110 by a controller 140 in the form of a processor.

[0212] Controller 140 may be configured to detect operation of user interface 114. Controller 140 may operate in accordance with a detected operation of one or more controls of user interface 114 by a user.

[0213] The controller 140 acts as an analysis and feedback module which is configured to carry out the various treatment feedback algorithms described below with respect to at least Figs. 4A, 4B, 5, 6 and 7.

[0214] Controller 140 may be configured to operate one or more indicators 116. For example, an indicator 116 may be operated to indicate a current state or status of operation of controller 140 or a component of electrical system 120.

[0215] Controller 140 may communicate with components and circuitry for generating a radiofrequency electromagnetic signal. Specifically, the controller 140 may control radio frequency electromagnetic signal generator 144. The radio frequency electromagnetic signal generator 144 is configured to supply a radio frequency electromagnetic signal to the electrodes 145 such that a radio frequency electromagnetic energy is applied to the skin. Radio frequency electromagnetic signal generator 144 may represent one or more components or modules of controller 140, may include components that are separate from controller 140, or both. A radiofrequency electromagnetic signal that is generated by radio frequency electromagnetic signal generator 144 may be conducted to one or more massaging arms 112 and ultimately to the electrodes 145 on each of the massaging arms 112 so as to induce a radiofrequency electrical current to flow in skin that is in contact with electrodes 145. Controller 140 and / or radio frequency electromagnetic signal generator 144 may be configured to measure the impedance between the electrodes 145, as would be understood by those skilled in the art. Accordingly, the electrodes 145 may be used, during operation, to measure the impedance of the skin between the electrodes 145.

[0216] Electrical system 120 may connect to or communicate with at least one sensing circuitry 130. In some embodiments, the at least one sensing circuitry can include one or more temperature sensors. A temperature sensor may be mounted on a massaging arm 112. In some embodiments, a temperature sensor may be provided in each of the massaging arms 112. Each temperature sensor may sense the temperature of the skin at the respective contact point of the corresponding massaging arm 112 with the skin. Thus, the temperature sensor is configured to sense the temperature of the skin at the point of contact where the electromagnetic radio frequency signal is provided to the skin, thereby ensuring better accuracy in sensing temperature of the skin at the contact points receiving the electromagnetic radio frequency signal. In some embodiments, the at least one sensing circuitry can include one or more sensors operable to sense (or measure) impedance and / or conductivity of the skin between the electrodes 145. In some embodiments, the at least one sensing circuitry can be at least partially constituted by at least one of the electrodes.

[0217] In certain embodiments, at least one of the one or more temperature sensors can be positioned at any portion of the housing other than the massaging arm(s).

[0218] The controller 140 may control radio frequency electromagnetic signal generator 144 to select a radiofrequency electromagnetic signal on the basis of operation by a user of a user interface 114, measurements from the temperature sensor(s), measurements of the impedance between electrodes 145, the program instructions stored on data storage 142 and any other measurements carried out by the skin treatment device 110.

[0219] Controller 140 may communicate with components and circuitry for controlling motion of moving components, such as massaging arms 112. Motion controller 148 may be configured to operate motor 122. For example, motion controller 148 may be configured to adjust an electrical current that is provided to drive motor 122 so as to operate drive motor 122 at a particular speed. Operation of drive motor 122 may cause massaging arms 112 to move in a predetermined manner. Electrical system 120 may include a power supply 150. Power supply 150 may provide power for operation of controller 140 or for operation of another component of electrical system 120. Power supply 150 may include a replaceable or rechargeable power source, such as a replaceable or rechargeable battery or cell. Power supply 150 may connect to an external power source, such as an electric power grid, generator, or power supply device, via connector 118.

[0220] The electrical system 120 may further comprise a communication module 160. The controller 140 may act to control the communication 160 to communicate with the user device 190, as described herein. The communication module 160 may enable a Bluetooth® connection with the user device 190. In certain embodiments, for example in which the skin treatment system does not include the user device, the communication module 160 may enable the skin treatment device to communicate with the practitioner system 200, either directly or via the server 400, for example over the computer network 300.

[0221] The skin treatment device 110 is configured to be operated according to a treatment plan (interchangeably referred to herein as treatment protocol and / or treatment). The treatment plan may be stored in the skin treatment device 110 and / or the user device 190. The treatment can include one or more treatment sessions requiring interaction of the skin treatment device, for example the skin treatment device 110, with the skin of the user. For example, a treatment session can include interacting by the user the skin treatment device 100 with the skin at an area to be treated (generally referred to herein as treatment area). A treatment can include the treatment sessions to be performed at certain time intervals, for example, a few hours, a day, a few days, a week, or a few weeks. Certain operating criteria (e.g., duration of treatment, power of treatment, size of treatment area, etc.) of the skin treatment device 110 for each treatment session may automatically be set according to the treatment plan.

[0222] For example, the treatment plan may be configurable by the practitioner system 200, as described further below. For example, the practitioner using the practitioner system 200 may define an initial treatment plan (treatment protocol or treatment) and this may be (remotely) updated based on the treatment results, frequency of treatment or any other information measured by skin treatment device 110 or reported by the user. In the case where the treatment plan is remotely updated, the user may get an alert, for example via the user device 110 (e.g. a push alert). In certain embodiments, the practitioner and practitioner system 200 may regularly monitor the ongoing treatment and / or may receive automatic alerts via the practitioner system 200 based on irregularities, deviations, outliers info, etc. detected by the computer systems.

[0223] Fig. 4A is a flow chart showing operation 500 of the skin treatment system 100 in accordance with an embodiment of the present disclosure. It is to be understood herein that operation 500 illustrates an operation of the skin treatment system 100 including the operation of the skin treatment device 110 by a user for performing a treatment session of a treatment on a skin of the user. For example, the treatment session which is at any given time being performed by the user has been referred to herein as an ongoing treatment session. For example, the treatment session that has once been started (initiated) and has not been yet finished has been referred to herein as an ongoing treatment session. The operation 500 depicts a computer implemented method (at least a part of which is performed by a computer processor, for example the controller 140) for assisting a user during an ongoing treatment session being performed by the user using a skin treatment system.

[0224] The user initiates a treatment session by turning on the skin treatment device 110 and starting an interaction of the skin treatment device 110 with the skin, for example by touching the massaging arms at the skin and moving the housing across the skin. The electrodes come into an electrically conductive contact with the skin of the user. A lubricating fluid, gel, or cream may be applied to the massaging arms and / or to the skin of the user. The lubricating fluid, gel, or cream may be electrically conducting. The radio frequency electromagnetic signal generator supplies a radio frequency electromagnetic signal to the electrodes, which applies a radio frequency electromagnetic energy to the skin. The radio frequency electromagnetic energy heats the skin. In some embodiments, the user can select a body part of the user at which the treatment session is to be performed, thereby defining an anatomical position of the skin being treated, as shown in the exemplary user interface screen of Fig. 11.

[0225] At step 510, the sensing circuitry 130 measures in real-time at least one parameter indicative of one or more characteristics of an interaction of the skin treatment device with the skin during the ongoing treatment session. It is to be understood herein that for the purposes of the present description, a function being performed real time is intended to mean at least that the function is performed while the ongoing treatment session is being performed, and the ongoing treatment session has not yet ended (terminated).

[0226] The at least one parameter can comprise at least one of skin impedance, conductivity between the at least two electrodes, temperature of the skin, and ambient temperature. The one or more characteristics of the interaction of the skin treatment device with the skin comprise area of the movement of the housing across the skin, speed of the movement of the housing across the skin, direction of the movement of the housing across the skin, and the electrically conductive contact of the at least two electrodes with the skin. The measured parameters, in general, can be indicative of the quality of contact between the device and the skin surface.

[0227] The analysis and feedback module (for example, the controller 140) receives (from the sensing circuitry) in real time the measurement of the at least one parameter. It is to be understood herein that for the purposes of the present description, the analysis and feedback module receiving the measurement of the at least one parameter in real time is intended to mean that the analysis and feedback module receives the measurement of the at least one parameter while the ongoing treatment session is being performed, and the ongoing treatment session has not yet ended (terminated). It is to be further understood herein that for the purposes of the present description, the analysis and feedback module receiving the measurement of the at least one parameter in real time is intended to mean that the analysis and feedback module receives the measurement of the at least one parameter within at most 30 seconds, 25 seconds, 20 seconds, 15 seconds, 10 seconds, 5 seconds, 3 seconds, 2 seconds, or 1 second of the sensing circuitry measuring the at least one parameter.

[0228] At step 520, the analysis and feedback module performs in real time an analysis of the received measurement to determine the one or more characteristics of the interaction of the skin treatment device with the skin during the ongoing treatment session. It is to be understood herein that for the purposes of the present description, the analysis and feedback module performing the analysis of the received measurement in real time is intended to mean that the analysis and feedback module performs the analysis while the ongoing treatment session is being performed, and the ongoing treatment session has not yet ended (terminated). It is to be further understood herein that for the purposes of the present description, the analysis and feedback module performing the analysis of the received measurement in real time is intended to mean that the analysis and feedback module performs the analysis within at most 30 seconds, 25 seconds, 20 seconds, 15 seconds, 10 seconds, 5 seconds, 3 seconds, 2 seconds, or 1 second of receiving the measurement.

[0229] In general, the analysis of the received measurement to determine the one or more characteristics of the interaction of the skin treatment device with the skin can include comparing a measured value (or measured values) of the at least one parameter with a predetermined (stored) value (or values) of the at least one parameter to determine that the measured value deviates from the predetermined value. The predetermined value(s) can be stored in the memory, for example, as a part of the treatment plan prescribed by the practitioner. The predetermined value(s) of the at least one parameter can be associated with the value of the at least one parameter at a given time during the treatment session that is desired for the accurate (for example, within a tolerance range) performance of the treatment session(s). Accordingly, the measured value (or measured values) of the at least one parameter at a given time is compared with the predetermined value(s) of the at least one parameter at that given time during the treatment session. Any given time can be for example, a predetermined time after the start of the treatment session.

[0230] In some examples, the deviation can be compared to a predetermined threshold value for the deviation, and based on the deviation, one or more characteristics of the interaction of the skin treatment device with the skin are determined, as described in detail further below.

[0231] The deviation (or in some examples, deviation beyond a threshold) of the measured value(s) from the predetermined value(s) can indicate that the ongoing treatment session is being performed inaccurately. It is to be understood herein that for the purposes of the present description, a treatment session being performed inaccurately is intended to mean that the treatment session is not being performed in the manner that was prescribed in the treatment plan by the practitioner.

[0232] In some embodiments, the analysis of the received measurement to determine the one or more characteristics of the interaction of the skin treatment device with the skin can include comparing a measured value (or measured values) of the at least one parameter with a predetermined range of values of the at least one parameter to determine that the measured value deviates from the predetermined range. The predetermined range of values can be stored in the memory, for example, as a part of the treatment plan prescribed by the practitioner. The predetermined range of values of the at least one parameter can be associated with the range of values of the at least one parameter at a given time during the treatment session that is desired for the accurate (for example, within a tolerance range) performance of the treatment session(s). Accordingly, the measured value (or measured values) of the at least one parameter at a given time is compared with the predetermined range of values of the at least one parameter at that given time during the treatment session. Any given time can be for example, a predetermined time after the start of the treatment session. The deviation (or in some examples, deviation beyond a threshold) of the measured value(s) from the predetermined range of values can indicate that the ongoing treatment session is being performed inaccurately. It is to be understood herein that the deviation (or in some examples, deviation beyond a threshold) of the measured value(s) from the predetermined range of values can mean that the measured value(s) is outside the predetermined range of values.

[0233] In some embodiments, the at least one sensing circuitry can be configured to measure in real time a pattern of values of the at least one parameter over a predetermined timeperiod. The pattern can be a time-variation pattern of the at least one parameter over the predetermined time-period. For example, the at least one sensing circuitry can be configured to continuously (or at short pre-set time intervals) measure the values of the at least one parameter over the predetermined time-period, the measured values constituting the pattern of the values of the at least one parameter. The analysis and feedback module can be configured to, for example based on the analysis of the received measurement, determine a deviation of the measured pattern of values of the at least one parameter from a predetermined pattern of values of the at least one parameter during the ongoing treatment session. The predetermined pattern of values can be stored in the memory, for example, as a part of the treatment plan prescribed by the practitioner. The predetermined pattern of values of the at least one parameter can be associated with the pattern that is desired for the accurate (for example, within a tolerance range) performance of the treatment session(s). Accordingly, the deviation (or in some examples, deviation beyond a threshold) of the measured pattern from the predetermined pattern can indicate that the ongoing treatment session is being performed inaccurately. In some embodiments, the pattern of the measured values constitute a slope (curve or graph) of the measured values with respect to time. Also, in such embodiments, the predetermined pattern can constitute a slope (curve or graph) of the predetermined values with respect to time.

[0234] In some embodiments, the predetermined value(s) and / or patterns can be associated with the anatomical position of the skin (based on the body part) being treated during the ongoing treatment session. Accordingly, the analysis can take into account the anatomical position of the skin being treated, thereby potentially increasing the efficacy of the whole process. For instance, as shown in Fig. 11, a user can select, at start of a treatment session, a body part to be treated in the treatment session, thereby selecting the anatomical position of the skin. Accordingly, for that treatment session, the analysis and feedback module can perform analysis according to the predetermined value(s) and / or patterns associated with the anatomical position of the skin.

[0235] In some embodiments, the above-described comparison of the measured value(s) and / or pattern with the predetermined value(s), range, and / or pattern can be done continuously, and the deviation can be determined as being an indication of the ongoing treatment session being performed inaccurately only if the deviation is observed for a predetermined time-period. For instance, if the deviation is observed for less than the predetermined time-period, the deviation can be ignored and may not indicate that the ongoing treatment session is being performed inaccurately.

[0236] At step 530, the analysis and feedback module provides in real time a treatment feedback based on the analysis to the user via a user interface of the skin treatment system (user interface can be of the skin treatment device and / or the user device). The treatment feedback comprises one or more guidance instructions instructing the user how to change the interaction of the skin treatment device with the skin during the ongoing treatment session. It is to be understood herein that for the purposes of the present description, the analysis and feedback module providing the treatment feedback in real time is intended to mean that the analysis and feedback module provides the treatment feedback while the ongoing treatment session is being performed, and the ongoing treatment session has not yet ended (terminated). It is to be further understood herein that for the purposes of the present description, the analysis and feedback module providing the treatment feedback in real time is intended to mean that the analysis and feedback module provides the treatment feedback within at most 30 seconds, 25 seconds, 20 seconds, 15 seconds, 10 seconds, 5 seconds, 3 seconds, 2 seconds, or 1 second from the measurement of the at least one parameter.

[0237] In some embodiments, the duration of the “real time” for providing feedback can vary, for example based on the type of guidance instructions given to the user and / or based on the at least one parameter that is being measured by the sensing circuitry. For example, if the treatment feedback pertains to loss of contact with the skin, the “real time” duration can be less than 5 seconds; if the treatment feedback pertains to movement of the device on the skin, the “real time” duration can be less than 15 seconds, 30 seconds, or 20 seconds.

[0238] In some embodiments, the skin treatment system can comprise a user device, for example the user device 190, and either or both of the user interface and analysis and feedback module can constitute a part of the user device. In some examples, the analysis and feedback module can constitute a part of the user device and the user interface can constitute a part of the skin treatment device. In some examples, the user interface can constitute a part of the user device and the analysis and feedback module can constitute a part of the skin treatment device. In some examples, both of the user interface and analysis and feedback module can constitute a part of the user device.

[0239] In some embodiments, the skin treatment system may not comprise a user device, and both of the user interface and analysis and feedback module can constitute a part of the skin treatment device.

[0240] In some embodiments, the user interface can include a display and the treatment feedback comprises visual feedback. In some embodiments, the user interface can include a speaker and the treatment feedback comprises audio feedback.

[0241] In some embodiments, the treatment feedback can comprise one or more guidance instructions instructing the user to change a speed of the movement of the housing across the skin during the ongoing treatment session, for changing the interaction of the skin treatment device with the skin.

[0242] In some embodiments, the treatment feedback can comprise one or more guidance instructions instructing the user to adjust an area of the movement of the housing across the skin during the ongoing treatment session, for changing the interaction of the skin treatment device with the skin.

[0243] In some embodiments, the treatment feedback can comprise one or more guidance instructions instructing the user to adjust the electrically conductive contact of the at least two electrodes with the skin during the ongoing treatment session, for changing the interaction of the skin treatment device with the skin. For instance, the treatment feedback can comprise instructions instructing the user to change an orientation of the skin treatment device with respect to the skin. For instance, the treatment feedback can comprise instructions instructing the user to press closer to the skin.

[0244] In some embodiments, the treatment feedback can comprise one or more guidance instructions for the user pertaining to improving the efficacy of the ongoing treatment session.

[0245] In some embodiments, the treatment feedback can comprise one or more guidance instructions instructing the user how to change the interaction of the skin treatment device with the skin for performing the ongoing treatment session accurately. For instance, if it is determined, as detailed above, that the ongoing treatment session is not being performed accurately, the treatment feedback can comprise one or more guidance instructions instructing the user how to change the interaction of the skin treatment device with the skin for performing the ongoing treatment session accurately. The inaccuracy in the ongoing treatment session and the instructions instructing the user how to change the interaction of the skin treatment device with the skin for performing the ongoing treatment session accurately, can be based on the measured parameter(s) and the characteristics of the ongoing treatment session indicated by the measured parameter(s), as described in detail below.

[0246] In some embodiments, the at least one parameter can comprise at least one of skin impedance and conductivity between the at least two electrodes. For example, a value at a given time or a pattern of the skin impedance and / or conductivity between the at least two electrodes can be measured. The measured value(s) and / or pattern can be compared to a predetermined value or range of values at the given time and / or predetermined pattern to determine a deviation, as described above. The deviation can indicate that the measured value(s) and / or pattern of at least one of skin impedance and conductivity between the at least two electrodes is not expected value(s) and / or pattern. Thus, the deviation can indicate that the contact of the electrodes with the skin is not accurate. For example, the skin impedance and conductivity between the at least two electrodes can deviate from the predetermined value(s) and / or pattern if one or both of the electrodes is / are not in a proper contact with the skin. Accordingly, the treatment feedback can comprise one or more guidance instructions instructing the user to adjust the electrically conductive contact of the at least two electrodes with the skin during the ongoing treatment session. For example, as shown in Fig. 9A, the instructions can instruct the user to “press the device closer” to the skin. In some embodiments the instructions can instruct the user to “adjust the orientation of the device” with respect to the skin.

[0247] In some embodiments, the predetermined values of expected skin impedance and / or conductivity are associated with the anatomical skin region that is being treated. For example, in regions in which the skin surface is curvy, e.g. on the face, the device can be set to “tolerate” more loss of contact as compared to, for example, less curvy skin surfaces such as the thighs. In another example, the predetermined values of expected skin impedance and / or conductivity are associated with an expected texture of the skin at the treatment region , for example, skin on the legs or feet may be rough and bumpy than, for example, facial skin, thus potentially affecting the expected skin impedance and / or conductivity when contacted by the electrodes.

[0248] It is to be understood herein that skin impedance and / or conductivity between the at least two electrodes can be measured by the electrodes, and thus in some examples, the electrodes can at least partially constitute the sensing circuitry.

[0249] In some embodiments, the at least one sensing circuitry can comprise at least one temperature sensor, and the at least one parameter can comprise at least one temperature of the skin.

[0250] In some embodiments, the at least one temperature sensor can comprise a first temperature sensor for measuring a first temperature of the skin at a first location on the skin, and a second temperature sensor, for measuring a second temperature of the skin at a second location on the skin spaced apart from the first location. The at least one parameter can comprise at least one of: the first temperature, the second temperature, a difference between the first temperature and the second temperature, an average of the first temperature and the second temperature, a pattern of the difference between the first temperature and the second temperature over a predetermined time-period. In some embodiments, the pattern of the difference between the first temperature and the second temperature over a predetermined time-period can constitute a slope (curve or graph) of the difference between the first temperature and the second temperature with respect to time. It is to be understood herein that for the purposes of conciseness and ease of understanding of the present description, all of the first temperature, the second temperature, the difference between the first temperature and the second temperature, the average of the first temperature and the second temperature, the pattern of the difference between the first temperature and the second temperature have been collectively referred to herein as the temperature of the skin. The difference between the first temperature and the second temperature, and the average of the first temperature and the second temperature collectively have been referred to herein as comparison metric of the first and second temperatures.

[0251] In certain embodiments, the first temperature sensor can be positioned at a first electrode of the at least two electrodes and the second temperature sensor can be positioned at a second electrode of the at least two electrodes, and the first and electrodes can be spaced from each other.

[0252] Accordingly, a value at a given time or a pattern of the temperature of the skin can be measured. The measured value(s) and / or pattern can be compared to a predetermined value or range of values at the given time and / or predetermined pattern to determine a deviation, as described above. The deviation can indicate that the measured value(s) and / or pattern of temperature of the skin is not expected value(s) and / or pattern. Thus, the deviation can indicate that the contact of the electrodes with the skin is not accurate, the area of the movement of the housing across the skin is larger or smaller than a predetermined area, and / or speed of the movement of the housing across the skin is higher or lower than a predetermined speed. For example, if the temperature of the skin does not rise to the predetermined temperature in a given time, this may indicate that either the contact of the electrodes with the skin is not accurate, the area of the movement of the housing across the skin is larger than a predetermined area, and / or the speed of movement of the housing across the skin is higher than a predetermined speed. For example, if the temperature of the skin exceeds the predetermined temperature in a given time, this may indicate that either the area of movement of the housing across the skin is smaller than a predetermined area, and / or the speed of movement of the housing across the skin is lower than a predetermined speed.

[0253] Further, the skin treatment device is moved across the skin, for example, within an area. The skin treatment device passes over different regions of the skin within that area periodically during the movement. Each instance of the skin treatment device passing over a region heats up that region (by RF electromagnetic energy). Until the skin treatment device passes over that region again, the region tends to cool down. For example, in between consecutive instances of the skin treatment device passing over a region, the region cools at least a little bit. This drop in temperature between consecutive instances can constitute a parameter indicative of the speed of movement of the skin treatment device on the skin. For instance, slower the speed of movement, greater is the drop in temperature of the region in between instances of the skin treatment device passing over the region. If the drop in temperature is greater than a predetermined value, this can be indicative of the fact that the area is larger than prescribed and / or the speed of movement is slower than prescribed, and thus the treatment feedback can include instructions guiding the user to reduce the area of movement and / or increase the speed. If the drop in temperature is smaller than a predetermined value, this can be indicative of the fact that the area is smaller than prescribed and / or the speed of movement is greater than prescribed, and thus the treatment feedback can include instructions guiding the user to increase the area of movement and / or reduce the speed.

[0254] Accordingly, the treatment feedback can comprise one or more guidance instructions instructing the user to adjust at least one of: area of the movement of the housing across the skin, speed of movement of the housing across the skin, and contact of the skin treatment device with the skin. For example, as shown in Fig. 9B, the instructions can instruct the user to adjust the area of movement of the skin treatment device to “make smaller circles” on the skin. In some embodiments the instructions can instruct the user to “slow down” to adjust the speed of movement of the skin treatment device.

[0255] The treatment feedback being provided in real time allows the user to implement the instructions in the feedback in real time to adjust the interaction of the skin treatment device with the skin. For example, the user can operate the device with one hand while holding the user interface in the other hand to follow the instructions. In some embodiments, the user interface can be on the skin treatment device at a location where the user need not hold the device for operation. In general, the real time feedback and continuous determining of the at least one parameter allows immediate detection of an inaccuracy in the manner of operation of the device by the user, and the user can be assisted in real time (within a few seconds, or a second, or even lesser than that) to perform the treatment accurately, and in particular to operate the device accurately. The user interface is, in some embodiments, continuously synchronized with the treatment device, enabling the issuance of immediate notifications and instructions to the user.

[0256] It is to be understood herein that in some embodiments, the measured value(s) and / or pattern of the at least one parameter may not deviate from the predetermined value(s) and / or pattern, thereby indicating that the ongoing treatment session is being performed accurately. Accordingly, for example at step 540, the treatment feedback can comprise guideline instructions instructing the user to continue the interaction of the skin treatment device with the skin without any change. For example, as shown in Fig. 9C, the instructions can instruct the user to continue, for example by notifying that the user “is doing great.”

[0257] At step 550, it is determined that whether the ongoing treatment session is complete (i.e., terminated) or not. If the ongoing treatment session is not complete, the process moves to step 510 to continue with the loop of measurements, analysis, and real time treatment feedback. If the ongoing treatment session is complete, the process ends at step 560.

[0258] It is to be understood herein that the skin treatment device can be configured to operate in a warmup phase and a treatment phase. For example, the skin treatment device can be configured to operate in the warmup phase when (until) a temperature of the skin is below a predetermined (target) value (of temperature), and in the treatment phase when the temperature of the skin is (reaches) above the predetermined (target) value (of temperature). The analysis and feedback module can be configured to provide in real time the treatment feedback at least in one of the warmup phase and the treatment phase, as described herein further below.

[0259] Fig. 4B is a flow chart showing operation 1000 of the skin treatment device 110 in accordance with an embodiment of the present disclosure. At step 1100 the skin treatment device 110 is turned on by a user. At this step, the user may use user interface 114 to set various user settings for the skin treatment device 110 and treatment settings may be received from the data storage 142, as described above.

[0260] In certain embodiments, the treatment device 110 receives the treatment settings directly from the server 400 via the computer network. For example, the data storage 142 may be optional and therefore omitted from the treatment device 110 (or, in alternative embodiments, the data storage 142 may have limited capacity). In such circumstances, the treatment device 110 may receive treatment settings from the server 400 without storing the settings on the data storage 142.

[0261] At step 1200, the skin treatment device 110 is configured to operate in an initial warmup phase, where the skin treatment device 110 aims to bring the temperature of the treatment area up to a target temperature. The skin treatment device 110 is brought into contact with the user’s skin and the controller 140 controls the radio frequency electromagnetic signal generator 144 to supply a radio frequency electromagnetic energy to heat the skin. The skin’s treatment area is heated to a target temperature during the initial warmup phase 1200. During the entirety of the treatment, the user moves the skin treatment device 110 around the treatment area of the skin.

[0262] As described in detail below, during the initial warmup phase 1200, the skin treatment device 110 is configured to measure at least one parameter of the treatment session. For example, the at least one measured parameter may include at least one measurement of skin temperature by the temperature sensors and a measurement of conductivity between the electrodes 145. At step 1290 (collectively used for 1290a and 1290b), the measured data is analyzed and treatment feedback is provided in real time to the user with a user interface at step 1290, for example as described in detail above.

[0263] When the temperature of the treatment area of the skin suitably meets the target temperature (e.g. for a predetermined amount of time), the skin treatment device 110 is configured to transition to a treatment phase 1300. Again, the controller 140 controls the radio frequency electromagnetic signal generator 144 to supply a radio frequency electromagnetic energy (typically at a lower power than that during the initial warmup phase 1200) to heat the skin. In this manner, the skin’s treatment area is maintained at the target temperature during the treatment phase 1300. During the entirety of the treatment, the user moves the skin treatment device 110 around the treatment area of the skin.

[0264] As described in detail below, during the treatment phase 1300, the skin treatment device 110 is configured to measure at least one parameter of the treatment. For example, the at least one measured parameter may include at least one measurement of skin temperature by the temperature sensors and a measurement of conductivity between the electrodes 145. At step 1390(collectively used for 1290a and 1290b), the measured data is analyzed and treatment feedback is provided in real time to the user with its user interface at step 1390.

[0265] Once the treatment phase 1300 is complete, the treatment session has been completed as the device may be turned off at step 1400.

[0266] Various treatment feedback algorithms (and corresponding measured parameters) are used during each of the initial warmup phase 1200 and the treatment phase 1300 to provide tailored treatment feedback to the user.

[0267] Fig- 5 is a flow chart showing such a treatment feedback algorithm 1210. The skin treatment system 100 is configured to run the treatment feedback algorithm 1210, with the skin treatment device 110 and user device 190 optionally carrying out various steps, as described below. In some embodiments, the steps of the user device can be performed by the skin treatment device itself. The treatment feedback algorithm 1210 is configured to run during the above-noted initial warmup phase 1200.

[0268] At step 1211, the skin treatment device 110 is configured to measure at least one parameter, such as at least one of: a first temperature and a second temperature. First and second temperatures may be measured using temperature sensors. Specifically, a first temperature sensor of the temperature sensors is configured to measure a first temperature of the skin. A second temperature sensor of the temperature sensors is configured to measure a second temperature of the skin. The first temperature sensor and the second temperature sensor are spaced apart such that the first temperature of the skin is measured at a spaced apart location from a location at which the second temperature of the skin is measured. The parameter may be measured over a period of time during the initial warmup phase 1200. At step 1212, a warmup temperature indicator is determined based on at least one of: the first temperature, the second temperature and a comparison metric indicative of a comparison between the first temperature and the second temperature. A time variation of the warmup temperature indicator is determined based on the warmup temperature indicator over different points in time. The warmup temperature indicator and / or the time variation of the warmup temperature indicator may be calculated by the skin treatment device 110 (e.g. by controller 140) or by the user device 190 (e.g. after receiving the measured parameters from the skin treatment device 110).

[0269] At step 1213, the time variation of the warmup temperature indicator is compared to a predetermined warmup temperature indicator pattern. The predetermined warmup temperature indicator pattern may be stored in the skin treatment device 110 (e.g. in the data storage 142) and / or in the user device 190. The comparison of the time variation of the warmup temperature indicator and the predetermined warmup temperature indicator pattern includes determining whether a deviation exists between the warmup temperature indicator and the predetermined warmup temperature indicator pattern. For example, it may be determined whether a deviation between the warmup temperature indicator and the predetermined warmup temperature indicator pattern exceeds a warmup temperature difference threshold over a predetermined time period.

[0270] If a difference between the warmup temperature indicator and the predetermined warmup temperature indicator pattern is not detected, for example, over a predetermined time period, at step 1290a, corresponding treatment feedback is provided via the user interface of user device 190. For example, the user interface of the user device 190 may show a message noting that treatment is being carried out correctly, a size of the treatment area is correct and / or the speed of movement of the skin treatment device 110 is correct. Step 1290a is purely optional, and instead, if a difference between the warmup temperature indicator and the predetermined warmup temperature indicator pattern is not detected, the treatment feedback algorithm 1210 may immediately move to step 1214.

[0271] If, at step 1213, a difference between the warmup temperature indicator and the predetermined warmup temperature indicator pattern is detected, for example, over a predetermined time period, at step 1290b, corresponding treatment feedback is provided via the user interface of user device 190. For example, the user interface of the user device 190 may show a message noting that treatment is not being carried out correctly, a size of the treatment area is too large and / or the speed of movement of the skin treatment device 110 is too large.

[0272] In certain embodiments, the warmup temperature indicator includes the first temperature and / or the second temperature, and detecting a deviation from the predetermined warmup temperature indicator includes a slope of the first temperature and / or the second temperature over time being below a predetermined slope threshold over a predetermined time period.

[0273] Once either treatment feedback is provided at step 1290a or step 1290b, the treatment feedback algorithm 1210 moves to step 1214. The corresponding treatment feedback provided at step 1290a or step 1290b may be maintained on the user interface of the user device 190 until updated treatment feedback (e.g. at the next instance of step 1290a or step 1290b) is provided.

[0274] At step 1214, the treatment feedback algorithm 1210 checks whether the initial warmup phase 1200 is completed. If the initial warmup phase 1200 is not completed, the treatment feedback algorithm 1210 loops back to step 1211, optionally, with a time delay.

[0275] If the initial warmup phase 1200 is completed, the treatment feedback algorithm 1210 ends at step 1215.

[0276] Fig- 6 is a flow chart showing another treatment feedback algorithm 1220. The skin treatment system 100 is configured to run the treatment feedback algorithm 1220, with the skin treatment device 110 and user device 190 optionally carrying out various steps, as described below. In some embodiments, the steps of the user device can be performed by the skin treatment device itself. The treatment feedback algorithm 1220 is configured to run during the above-noted initial warmup phase 1200. The treatment feedback algorithm 1220 may be run concurrently with the treatment feedback algorithm 1210.

[0277] At step 1221, the skin treatment device 110 is configured to measure at least one temperature from temperature sensors. For example, the skin treatment device 110 may be configured to measure a first temperature and / or a second temperature using temperature sensors. Specifically, a first temperature sensor of the temperature sensors is configured to measure a first temperature of the skin. A second temperature sensor of the temperature sensors is configured to measure a second temperature of the skin. The first temperature sensor and the second temperature sensor are spaced apart such that the first temperature of the skin is measured at a spaced apart location from a location at which the second temperature of the skin is measured.

[0278] At step 1222, it is determined whether the first temperature, the second temperature and / or an average thereof is below a predetermined minimum temperature threshold during the initial warmup phase. The predetermined minimum temperature threshold may be stored in the data storage 142 of the skin treatment device 110 or in the user device 190.

[0279] If the first temperature, the second temperature and / or an average thereof is not below a predetermined minimum temperature threshold, corresponding treatment feedback is provided via the user interface of user device 190. For example, the user interface of the user device 190 may show a message noting that treatment is being carried out correctly. Step 1290a is purely optional, and instead, if the first temperature, the second temperature and / or an average thereof is not below a predetermined minimum temperature threshold, the treatment feedback algorithm 1220 may immediately move to step 1223.

[0280] If, at step 1222, the first temperature, second temperature and / or an average thereof is below a predetermined minimum temperature threshold, corresponding treatment feedback is provided via the user interface of user device 190. For example, the user interface of the user device 190 may show a message noting that treatment is not being carried out correctly and / or the temperature of the skin is too low.

[0281] Once either treatment feedback is provided at step 1290a or step 1290b, the treatment feedback algorithm 1220 moves to step 1223. The corresponding treatment feedback provided at step 1290a or step 1290b may be maintained on the user interface of the user device 190 until updated treatment feedback (e.g. at the next instance of step 1290a or step 1290b) is provided.

[0282] At step 1223, the treatment feedback algorithm 1220 checks whether the initial warmup phase 1200 is completed. If the initial warmup phase 1200 is not completed, the treatment feedback algorithm 1220 loops back to step 1221, optionally, with a time delay.

[0283] If the initial warmup phase 1200 is completed, the treatment feedback algorithm 1220 ends at step 1224.

[0284] Fig- 7 is a flow chart showing a treatment feedback algorithm 1310. The skin treatment system 100 is configured to run the treatment feedback algorithm 1310, with the skin treatment device 110 and user device 190 carrying out various steps, as described below. The treatment feedback algorithm 1310 is configured to run during the above-noted treatment phase 1300.

[0285] At step 1311, the skin treatment device 110 is configured to measure first and second temperatures 1311 using temperature sensors. Specifically, a first temperature sensor of the temperature sensors is configured to measure a first temperature of the skin. A second temperature sensor of the temperature sensors is configured to measure a second temperature of the skin. The first temperature sensor and the second temperature sensor are spaced apart such that the first temperature of the skin is measured at a spaced apart location from a location at which the second temperature of the skin is measured.

[0286] At step 1312, a difference between the measured first temperature and the measured second temperature is determined. The difference may be calculated by the skin treatment device 110 (e.g. by controller 140) or by the user device 190 (e.g. after receiving the measured first temperature and the measured second temperature from the skin treatment device 110).

[0287] At step 1313, it is determined whether a difference between the first temperature and the second temperature exceeds a threshold. The threshold may be predetermined and stored in the data storage 142 of the skin treatment device 110 or in the user device 190.

[0288] If the difference between the first temperature and the second temperature does not exceed the threshold, at step 1390a, corresponding treatment feedback is provided via a user interface. For example, the user interface of the user device 190 may show a message noting that treatment is being carried out correctly and / or a size of the treatment area is correct. Step 1390a is purely optional, and instead, if the difference between the first temperature and the second temperature does not exceed the threshold, the treatment feedback algorithm 1310 may immediately move to step 1314.

[0289] If, at step 1313, the difference between the first temperature and the second temperature does exceed the threshold, at step 1390b, corresponding treatment feedback is provided via the user interface of user device 190. For example, the user interface may show a message noting that treatment is not being carried out correctly and / or a size of the treatment area is too large or small. Once either treatment feedback is provided at step 1390a or step 1390b, the treatment feedback algorithm 1310 moves to step 1314. The corresponding treatment feedback provided at step 1390a or step 1390b may be maintained on the user interface until updated treatment feedback (e.g. at the next instance of step 1390a or step 1390b) is provided.

[0290] At step 1314, the treatment feedback algorithm 1310 checks whether the treatment phase 1300 is completed. If the treatment phase 1300 is not completed (for example, if the preset time for the treatment phase has not elapsed), the treatment feedback algorithm 1310 loops back to step 1311, optionally, with a time delay.

[0291] If the treatment phase 1300 is completed, the treatment feedback algorithm 1310 ends at step 1315.

[0292] It is to be understood herein that the predetermined pattern of values, the predetermined range of values, and / or the predetermined value of the at least one parameter is different in the warmup phase than that in the treatment phase.

[0293] During the treatment session, the skin treatment system 100 may measure one or more characteristics of the device interaction with the skin, and based on these characteristics, calculate one or more session performance metrics. The skin treatment system 100 may provide a treatment effectiveness indication (e.g. a score out of 100) to the user via the user interface. The treatment effectiveness indication may be provided at the end of the treatment session or periodically throughout the treatment. The treatment effectiveness indication (score) can be calculated based on cumulative data that was collected throughout a treatment session. In some cases, the collected data is recorded and optionally stored at a memory.

[0294] In certain embodiments, during the treatment session, the treatment effectiveness indication may be based on a determination of whether the first temperature, the second temperature and / or an average thereof decreases below the target temperature, for example, weighted by the difference to the target temperature and the time spent above / below the target temperature.

[0295] The various treatment feedback algorithms may be run separately or concurrently, and various forms of treatment feedback may be presented to the user throughout the treatment. The real-time treatment feedback may be used by the user to improve the treatment so as to increase efficacy. The treatment system 10 may be used by the practitioner to further improve the efficacy of treatment. In general, as detailed below, the treatment plan may be initially set by the practitioner (based on their experience, comparisons based on other treatments on other patients (e.g. using Artificial Intelligence / Machine Learning), etc.), and may then be subsequently updated as the user applies the treatment (e.g. over a period of days, weeks and months).

[0296] For example, Fig. 8 is a flow chart showing a method of updating a treatment plan by a treatment system, for example the treatment system 10. The treatment system 10 comprises the skin treatment system 100 and the practitioner system 200. The skin treatment system 100 and the practitioner system 200 are configured to perform the corresponding steps of the method described herein below.

[0297] At step 2100, the skin treatment system 100 is used to perform at least one treatment session of an initial treatment plan. The initial treatment plan may be constructed based on the practitioner’s prior knowledge / experience and / or using comparisons with prior treatments (e.g. using Artificial Intelligence / Machine Learning, etc.). The initial treatment plan may take into account certain patient characteristics, such as any combination of: age, gender, skin type, skin impedance, skin condition, patient goals, patient availability for treatment, etc.

[0298] The user initiates the at least one treatment session by turning on the skin treatment device 110 and starting an interaction of the skin treatment device 110 with the skin, for example by positioning the massaging arms on the skin surface (while holding onto a body of the device) and moving the housing across the skin. The electrodes come into an electrically conductive contact with the skin of the user, and the radio frequency electromagnetic signal generator supplies a radio frequency electromagnetic signal to the electrodes, which applies a radio frequency electromagnetic energy to the skin thereby heating the skin.

[0299] The skin treatment system 100 is configured to, for example by the analysis and feedback module, determine at least one session performance metric indicative of one or more characteristics of the at least one treatment session, and transmit the at least one session performance metric to a practitioner system. In certain embodiments, the at least one session performance metric can comprise a session effectiveness score. For instance, the session effectiveness score may be indicative of how effectively a treatment session was performed. In certain embodiments, the one or more characteristics of the at least one treatment session can comprise at least one of: number of times contact between the skin treatment device and the skin was lost during the at least one treatment session, number of times a temperature of the skin deviated from a predetermined value during the at least one treatment session, number of times the at least one treatment session was paused during the at least one treatment session, and duration of the at least one treatment session.

[0300] It is to be understood herein that if during the at least one treatment session, the contact between the skin treatment device and the skin was lost frequently, for example, for a greater number of times than a predetermined number, then the treatment session cannot be expected to be performed effectively. Similarly, if during the at least one treatment session, the temperature of the skin deviated from a predetermined temperature (or range of temperature values) frequently, for example, for a greater number of times than a predetermined number, then the treatment session cannot be expected to be performed effectively. Further, if during the at least one treatment session, the session was paused frequently, for example, for a greater number of times than a predetermined number, then the treatment session cannot be expected to be performed effectively. Also, if the total duration of the treatment session was different than a prescribed duration, the treatment session cannot be expected to be performed effectively.

[0301] Based on some or all of the above-mentioned characteristics, a session effectiveness score for one or more treatment sessions is calculated and transmitted to the practitioner system. In certain embodiments, the session effectiveness score can be shown to the user, for example, via a user interface (of the user device or the skin treatment device). For example, as shown in Fig. 10, the user interface can show a session effectiveness score thereby notifying the user that “repeated loss of contact” was detected.

[0302] In certain embodiments, the skin treatment system 100 can be configured to transmit the at least one session performance metric to the practitioner system 200, indirectly, for example via the server 400 over the computer network 300. For example, the at least one session performance metric (or representations thereof) can be uploaded to the server 400 via the computer network 300.

[0303] The server 400 may contain a database stored in the data store 410. The database may include a list of patients and corresponding patient data. At step 2200, the received at least one session performance metric may be matched to one of the patients stored in the database. The data store may include data including a plurality of usage events associated with a plurality of different patients, wherein each usage event is associated with a skin treatment device, a usage event type (home treatment, professional treatment, low power treatment, high power treatment, maintenance treatment, etc.) and one or more parameters of the usage event. The usage event parameters may include performance metrics, a time of the day and / or a date of said usage event. The usage event parameters may also include a duration of the usage event. The server 400 may then transfer, via the computer network 300, the one or more performance metrics with the associated patient data to the practitioner system 200. The practitioner system may enable to provide a prioritized filtered list of patients out of the plurality of patients using a dedicated Graphical User Interface e.g. based on a comparison of the usage events, usage event types and usage event parameters that are associated with the same patient. The practitioner system may be configured to compare different subsets of usage events to one another, where for instance, the different subsets of usage events may be associated with the same users. For example, the practitioner system may determine whether a number of usage events that are associated with the same user and usage event type is relatively smaller or greater than the number of usage events of a different, non-overlapping subset of the usage events that are associated with the same user and usage event type. In some instances, the different, non-overlapping subset of usage events is associated with a different date range than the number of usage events but is associated with the same usage event type and time of the day. This may enable to detect usage patterns. For example, the practitioner system may be configured to determine the users out of the subset of users who had more than X% increase in usage events over a period of time for a particular usage event type as compared to a different time period (e.g, the previous week). The practitioner system may also be configured to prioritize the listing of users to first indicate users with the lowest number or the highest number of usage events (e.g, over a particular time range, such as one month) of a particular usage event type.

[0304] In addition to the above, the patient data contained in the data store 410 may be used to determine (at least in part) the initial treatment plan at step 2100. For example, Artificial Intelligence / Machine Learning may be used with the existing patient data so as to recommend an initial treatment plan for review by the practitioner. Furthermore, the practitioner may propose treatment changes based on lessons learned from other existing treatments in the patient data.

[0305] In certain embodiments, at least one of the skin treatment system 100 and the practitioner system 200 can be configured to performed some or all of the functionalities of the server 400. In certain embodiments, the skin treatment system 100 and the practitioner system 200 can be configured to communicate directly, for example over the computer network 300.

[0306] At step 2300, the practitioner, using the practitioner system 200 and its user interface (practitioner user inteface), may review the at least one session performance metric received from the skin treatment system 100. The practitioner may construct a revised treatment plan based on the at least one session performance metric and transmit the revised treatment plan to the skin treatment system 100 (directly or via the server 400). The practitioner system may be capable of communicating reminders to the user device through the network.

[0307] At step 2400, the skin treatment system 100 may be updated with the updated treatment plan via the computer network 300.

[0308] At step 2500, the user may then perform another treatment according to the updated treatment plan. There may be a time delay (e.g. of a day, week or month) between step 2400 and step 2500.

[0309] In certain embodiments, the skin treatment system can be configured to determine at least one treatment performance metric indicative of one or more characteristics of the treatment. In certain embodiments, the at least one treatment performance metric can comprise a treatment effectiveness score. For instance, the treatment effectiveness score may be indicative of how effectively a treatment was performed. The treatment effectiveness score can be calculated based on a plurality of the session performance metrics, for example, by calculating an average of the plurality of the session effectiveness score corresponding to the plurality of the session performance metrics.

[0310] In this manner, the practitioner may review the progress of the in-home treatment performed by the patient / user and provide updated treatment plans according to the progress being made. This may improve the efficacy of the treatment.

[0311] Furthermore, basing the initial treatment plan on existing patient data, the prior treatments may be used to improve the initial treatment plan and therefore the efficacy of the overall treatment.

[0312] While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist.

[0313] For example, the skin treatment device 110 may measure various parameters of the treatment such as: impedance, movement speed / directi on, contact, skin temperature before treatment, ambient temperature. Any combination of these parameters may be used in any of the methods described herein to provide treatment feedback to the user and / or for monitoring by the practitioner using the practitioner system 200.

[0314] Furthermore, even though skin treatment device 110 is described as being configured to supply a radio frequency electromagnetic signal to heat the treatment area, this is purely optional, and any other skin treatment device is appliable to the methods disclosed herein.

[0315] Additionally, in certain embodiments, the practitioner system 200 may be connected (via the computer network 300) to a plurality of skin treatment systems 100 (and corresponding skin treatment devices 110). The plurality of skin treatment systems 100 may be used by different patients (e.g. in different locations).

[0316] It should also be appreciated that the exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration of the disclosure in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing the exemplary embodiment or exemplary embodiments. It should be understood that various changes can be made in the function and arrangement of elements without departing from the scope of the disclosure as set forth in the appended claims and the legal equivalents thereof.
