    [0001] The present invention relates to devices for performing a cosmetic treatment of keratin materials, in particular the skin, the scalp or the hair. "Cosmetic product" means any composition as defined in Council Directive 93/35 / EEC of 14 June 1993. It is known that the application of an electric current to the skin may promote the penetration of active ingredients. . It is thus known to treat human keratin materials using iontophoresis devices (J. Singh, KS Bhatia, topical iontophoretic drug delivery: pathways, principles, factors and skin irritation, Med Res Res, vol 16 , No. 3, 285-296, 1996).
    [0002] Iontophoresis allows the diffusion of actives through the skin through electrical stimulation in a non-invasive way. The current administered can be adjustable in intensity and direction (anodal or cathodal). Transcutaneous diffusion of molecules via iontophoresis is based on two principles: electrorepulsion and electroosmosis. Electrorepulsion is the migration of an ionized molecule by repulsion of charges of the same sign. Thus, if a substance is positively charged, it will diffuse through the skin at the (+) anode. Electroosmosis is the migration of a molecule, even if not ionized, by driving linked to the flow of water from the anode to the cathode during iontophoresis. The migration is due in particular to the negative charge of the skin. Under the effect of a current, the water or a solvent causes, during their migration, dissolved substances. The application of the electric current on the skin can be achieved by means of a tip. For large areas of the body or cheek of the face, the tip can be large. In areas more difficult to access, the tip may take the form of a small head easier to contact or move.
    [0003] However, the smaller the size of the tip, the longer the treatment time. This impacts on the effectiveness of the treatment. To overcome this problem, some devices on the market are equipped with different tips adapted to different specific body areas.
    [0004] Thus, the Nu-Skin Galvanic Spa System II ® product marketed by Nu Skin is offered with several tips of different shapes. The kit includes a mouthpiece for the face, a tip for the body and another for the scalp. Similarly, patent JP 2012-254168 discloses an iontophoresis apparatus whose tip is removable. Depending on the area treated, the user can choose a tip whose skin contact surface is flat or curved. On the forehead or in some situations where the tip is not quite well pressed on the skin during its movement, the intensity of current may be inhomogeneous on the treated area. For security, many devices have limited the current delivered to anticipate this problem. This also limits the effectiveness of the treatment. There is therefore a need for a cosmetic treatment device by an electric current that ensures a uniform current intensity on an area to be treated and is compact and inexpensive. There is therefore a need for a cosmetic treatment device by an electric current that can be used safely. For this purpose, the invention proposes to have several electrodes (or pads) on the same end and electrically isolate them from each other. Thus, each electrode is managed independently. The intensity of the current on each electrode is adjusted according to its degree of contact with the skin.
    [0005] For large areas of the body or the cheek, all the electrodes can be in contact with the skin. In areas that are more difficult to access, it is possible that only certain electrodes are in contact with the skin. Similarly, if the tip is not quite well pressed on the skin during its movement, only some electrodes are in contact with the skin.
    [0006] The device according to the invention makes it possible to detect the electrodes in contact with the skin and to power these electrodes only selectively. More specifically, the subject of the invention is a device for cosmetic treatment of keratin materials by an electric current comprising: a tip comprising at least two electrodes connected to the same polarities of at least one current generator; at least one counter-current; electrode, - a power supply system, the electrodes being managed independently of each other by the power supply system. According to the invention, the term "electrode" means an electrode positively charged (anode) or negatively (cathode). This electrode is generally disposed on the outer surface of the tip to come into direct contact with the keratin materials. But, the electrode can also be inserted into the outer wall of the tip. In this case, it does not come into direct contact with the keratin materials. In general, the electrode is in contact with the area to be treated.
    [0007] Throughout the text, the term "electrode" means a single isolated electrode. An electrode may be for example in the form of a ball or stud. The term "counter electrode" means a negatively charged electrode (cathode) or positively (anode) electrode. The charge of the counter-electrode is opposite to that of the electrode. In general, it is arranged on the body of the device or on a handpiece. The counter electrode is intended to come into contact with a body area of the person undergoing the treatment. For example, it can be grasped between the fingers of the person. In one configuration, the counter-electrode may be disposed on the tip. In this event, it is separated from the electrodes by an insulating space. The term "electrical supply system" means an electrical assembly capable of inducing a potential difference between the electrodes and the counter-electrode. If the tip is placed on the face and if the counter-electrode is held in one hand, the potential difference makes it possible to establish a current between the face and the hand. The expression "the electrodes are managed independently of each other by the power supply system" means that the electrodes are electrically isolated from each other. Each electrode is managed as an independent component. Its operation does not depend on that of the other electrodes. ELECTRIC CIRCUIT According to a first embodiment, the supply circuit comprises a plurality of current generators each connected to an electrode. In this case, each electrode is managed by its own current generator. This embodiment is of simple construction.
    [0008] According to a second embodiment of the invention, the supply circuit comprises at least one sensor for measuring the current (im) between each electrode and the keratin materials.
    [0009] Advantageously, the power supply circuit comprises a microcontroller adapted to control the voltage between each electrode and the counter-electrode, which makes it possible to control the current. Said voltage being slaved to the current (im) measured by the sensor. In this case, the supply circuit comprises at least one current generator connected to a plurality of electrodes. In other words, the electrodes are connected in parallel to at least one current generator. Advantageously, the device according to the invention comprises an electronic unit adapted to put on standby (or standby) the power supply of the electrodes if the current detected between an electrode and the skin is less than a predetermined threshold value (is). The potential difference between the electrode and the counterelectrode is maintained at a threshold value (Us) by the power supply circuit, in standby mode (or in standby mode) of the power supply. On the contrary, if the current (im) detected between an electrode and the skin is greater than this threshold value (is), the generator increases the current up to a value (Ii) predetermined greater than is. The current flows between the electrode and the counter-electrode through the skin. More preferably, the electronic unit comprises a plurality of current sensors for detecting the current value between each electrode and the skin. Preferably, the power supply circuit comprises a microcontroller. Preferably, the threshold current (is) is between 1.1A and 101.1A. The power supply at each electrode is slaved to the measurement of the current (im) detected between the electrode and the skin. This current is advantageously detected by a sensor. The current (im) is compared by a microprocessor to the value of the threshold current (is). If (im)> (is), then the generator delivers a supply current at the electrode up to a predetermined value (Ii).
    [0010] If (im) <(is), then the generator does not deliver additional current at the electrode. We are in a standby situation (or standby). Preferably, the current (Ii) is identified to reach a current intensity per unit area ranging from 0.01 mA / cm 2 to 0.5 mA / cm 2, preferably from 0.1 mA / cm 2 to 0.3 mA / cm 2 . It is understood that the term "microcontroller" refers to a single electronic device, such as for example a microprocessor chip, or for a set of programmable electronic elements, such as communication gateways for management by a device third party (PC type, PDA, etc.). More preferably, each electrode is connected to a switch. The latter is a means of detecting the presence of the current. It plays the role of current sensor. Even more advantageously, each electrode is surface-mounted on an electronic card. ELECTRICAL PARAMETERS The power source may include any battery or accumulator. The voltage between the electrodes is for example between 1.2 V and 24 V, preferably between 1.2 and 3.3 V. Where appropriate, the passage of the current can create a punctual heating. The source of electrical energy may comprise, for example, a DC voltage source. Alternatively, the source of electrical energy may comprise an electronic circuit for varying the amplitude of the voltage generated over time. This electronic circuit may, for example, be a chopper. At equivalent current density, the device can in particular deliver a current density, at the level of the skin, preferably less than or equal to 0.500 mA / cm 2, for example between 0.1 mA / cm 2 and 0.500 mA / cm 2, for example. example between 0.1 mA / cm2 and 0.30 mA / cm2.
    [0011] ELECTRODES The electrodes have an apparent free surface allowing them to directly contact the skin.
    [0012] The use of the device can be done by keys, the user handling the device with one hand and bringing the electrodes into contact with the skin. The user can move the device by keeping the electrodes in contact with the skin or spread the electrodes of the skin during the movement of the device between a first zone and a second zone.

Such a metal can be deposited in the form of a thin layer. According to one embodiment of the invention, the application surface is smooth.
    [0016] In this case, the device is particularly suitable for large areas such as cheeks or forehead, if a massage is not desired. According to another embodiment of the invention, the tip comprises an outer surface provided with at least one relief. In this case, the device can also be used to massage a selected body area. Advantageously, the relief comprises at least one boss on which the electrodes are arranged.

    [0024] FIG. 1 shows a device comprising three electrodes 101, 102 and 104 connected to a power supply 13. Two electrodes 102 and 104 are in contact with the skin 80. The electrode 101 is remote from the skin. This electrode 101 is supplied with current in the same manner as the electrodes 102 and 104 which are in contact with the skin 80. This supply of the electrode 101 is represented by the flash 14.
    [0025] To use the device, the user can move the tip on the skin 80 of a body area 12, after possibly having deposited on the skin or on the electrodes a cosmetic treatment product. FIG. 2 shows a device according to the invention comprising: three electrodes 101, 102 and 103 disposed on the external surface of the endpiece 25, a power supply 13. This device is used in the same way as the device of Figure 1. But, the operation is different as soon as at least one electrode is no longer in contact with the skin 80. In the example shown, two electrodes 102 and 104 are fully in contact with the skin 80 .
    [0026] On the other hand, for the electrode 101, the surface in contact with the skin is very small. There is a local heating at the electrode 101. The current is controlled at this electrode 101 by the power supply system according to the invention. The electrodes 101, 102 and 103 may be partially engaged in the tip 25, for example being held inside thereof by various support reliefs, which may be made by molding thermoplastic material with the housing. The electrodes have been shown with a substantially convex skin contacting surface, but the invention is not limited to a particular form of electrode surface for contacting the skin. The electrodes may be balls which are snapped into housings 26 molded in one piece with the endpiece 25. They may be free to rotate in their housings 26, according to the embodiments.
    [0027] Figure 3 shows a detail of a device according to the first embodiment of the invention. Three generators 1, 10 and 100 emit a current with a given power. Three electrodes 101, 102 and 104 are each respectively connected to the current generator 100, 10 and 1. The current is transmitted to a skin area 12 to be treated by each electrode 101, 102 and 104. The electrodes 101, 102 and 104 are electrically isolated. They are managed independently of each other, to adapt the intensity of the current to the number of electrodes that are in contact with the skin. Each electrode 101, 102 and 104 is managed by its associated generator 100, 10 and 1 parameterized to deliver a given current intensity. The device comprises an electrical circuit that selectively feeds the electrodes 101, 102 and 104. If an electrode is in contact with the skin, the electrical circuit connecting this electrode to the skin is closed. In this case, the power supply at said electrode is made.
    [0028] If an electrode is not in contact with the skin, the electrical circuit connecting this electrode to the skin is open. In this case, the power supply at said electrode is not performed.
    [0029] Figure 4 shows a detail of a device according to the second embodiment of the invention. A generator 1 emits a current with a given power. The three electrodes 101, 102 and 104 are connected in parallel with the current generator 1. The current is transmitted to a skin zone 80 to be treated by each electrode 101, 102 and 104. The question of the effectiveness of the treatment and the Homogeneity of the current on the skin area to be treated arises, especially at the periphery of the zone. For this purpose, the device comprises a microcontroller 3 adapted to control the voltage between each electrode 101, 102 and 104 and against the electrode 60. In order to control the current generated by the generator, in each loop of the electrode circuit, a switch 33 is placed to detect the presence of current. This information is communicated to the microcontroller 3. FIG. 5 shows a detail of a device according to the second embodiment of the invention. The device comprises the electrodes 101, 102 and 104. A current sensor 20 and a switch are also arranged in the electrical circuit. The microcontroller 3 controls the intensity of the current at the electrodes as a function of the measurements provided by the current sensor 20 and the type of care sought. The microcontroller 3 is powered by a battery 6 and receives the data measured by the current sensor 20. The microcontroller 3 also receives on / off commands and programming from a button 21 actuated by the user. Such a button 21 may be mechanical or tactile. The microcontroller 3 can also control the display of information on a screen, to allow the user to view the operating mode of the device. FIG. 6 represents a flowchart of a program implemented by the microcontroller of the device according to the second embodiment of the invention. When the device is activated (START) and a program chosen by the user, the microcontroller retrieves measured current reading data (i.,) From the current sensor. The current (i,) is compared by a microprocessor to the value of the threshold current (is).
    [0030] In the example shown, the current values are set as follows: - is-10 1.1A - the current (Ii) is identified to achieve a current intensity per unit area equal to 0.3 mA / cm2. If (im)> (is), then the generator delivers a supply current at the electrode up to a predetermined value (Ii). It is in position (i ON = Ii)) at the electrode. If (im) <(is), then the generator does not deliver additional current at the electrode. We are in a standby situation (or standby). It is in position (i OFF) at the electrode. The device may include an indicator light and / or a speaker to inform the user sensitively that the current emission of at least one electrode has been interrupted because the device is held too far from the treatment area. a given place. More specifically, the transmission power of each electrode can obey a specific servo law depending on the location of the electrode in the device (central or peripheral position) and / or depending on the type of electrode and / or function current (continuous or pulsed).
    [0031] FIG. 7 illustrates a tip 25 integrated in a device according to the invention with a counterelectrode 60. The electrodes 101, 102 and 104can be arranged on moving balls 41, 42 and 43. For example, the balls may be free to rotate around a core secured to the outer surface of the nozzle 25. The device may operate according to the first embodiment of the invention (FIG. 3) or according to the second embodiment of the invention. embodiment of the invention (Figure 4). The electrodes may constitute components of the "surface-mounted components" type. The device has a body 50 consisting of a shell on which is mounted the nozzle 25. The shell of the body 50 can accommodate other electronic components and a battery 6. The tip 25 can carry an electronic card on which is The current sensor 20 mentioned with reference to FIG. 6 and the microcontroller 3 are arranged. Any type of program may be envisaged within the scope of this invention for controlling pulsed and / or continuous and / or alternating current emissions.

This device may for example be used at home. The user grasps the body 50 with one hand. The counterelectrode 60 is grasped by the other hand. The user applies the tip 25 to the face (Figure 10). The electrodes that are in contact with the face are represented by empty circles. Electrodes that are not in contact with the face are represented by solid circles. In FIG. 10, all the electrodes 101, 102, 103, 104, 105, 106 and 107 are in contact with the face. The current passes at each of these electrodes. The user moves the tip on the face towards the nose for example (Figure 11).
    [0033] The electrodes 101, 102, 105, 106 and 107 are no longer in contact with the skin. The current is interrupted at these electrodes. It continues to pass at the level of the electrodes 103, 104. The user moves the tip towards the underside of the cheek (FIG. 12). The electrodes 101, 102, 103, 105, 106 and 107 are no longer in contact with the skin. The current is interrupted at these electrodes. It continues to pass at electrode 104 only. The present invention has been described with reference to particular embodiments, illustrated in FIGS. 1 to 12, and with reference to particular examples, but it is understood that other variants may be envisaged by those skilled in the art, in particular the number and types of electrodes may vary and other arrangements than those described may be envisaged to constitute devices according to the invention.
