    [0001] The present invention relates to an apparatus for skincare, in particular of the skin of the face, intended to provide care in various forms to produce a radiance effect, remodeling, anti-aging or anti-wrinkle. The care is provided by a contribution of light energy to the skin or even by a mechanical action massaging means. [21] A document KR20090001911 is known which teaches a massage apparatus comprising a care head comprising a vacuum chamber intended to suck the skin. The chamber incorporates two parallel rollers which are motorized so as to rotate in the same direction. The apparatus further comprises a light emitter in the bottom of the chamber behind said rollers. The light source is of the electroluminescent diode type, commonly called LED, intended to project light simultaneously to the movement of the rollers. The disadvantage of such an arrangement of the light source is that it is remote from the area to be projected, that is to say from the plane tangent to the outside of the rollers, so that the intensity of the projected light is diminished. In addition, a portion of the light beams is concealed by the two rollers, which reduces the effectiveness of the light treatment. Another known JP3155121 discloses a portable massage apparatus comprising a treatment disc rotated by a motor output shaft for contacting the skin. The apparatus comprises below said disk a plurality of light sources in the form of LEDs for illuminating the skin through said disk which is made of translucent material. The treatment by the projection of lights and the treatment by the movement of the disc are done simultaneously in order to achieve a better result. According to this document, the LEDs are arranged in a circle facing the treatment disk to emit light beams perpendicular to the skin. However, such an arrangement does not allow a homogeneous projection or requires a high number of LEDs to cover the entire projection surface, which increases the cost of the device. On the other hand, the efficiency of the light energy is not optimized, because the loss of energy is important when the light passes through the translucent disc. [4] The object of the present invention is to remedy at least in part the aforementioned drawbacks and to provide a skin care apparatus for providing at least one mechanical treatment combined with a light treatment on a defined area. [5] Another object of the invention is a skin care apparatus for homogeneous light scattering on the area. [6] Another object of the invention is a skin care apparatus for intense and effective skin illumination in the area. Another object of the invention is a skincare apparatus whose light sources make it possible to illuminate at least part of an area stressed by mechanical massage means with which they are associated. [8] Another object of the invention is a skin care apparatus with an arrangement of light sources and mechanical massage means optimized for compactness of the reduced apparatus. [9] Yet another object of the invention is a multifunctional skin care apparatus, easy to use and inexpensive. These goals are achieved with a skin care apparatus comprising a body having a housing forming a grip zone, power supply means arranged in said body, at least one care head, at least one light source. at least one light guide having a projection surface for receiving light emitted by said at least one light source and for projecting at least one light beam to an area on the skin. According to the invention, said at least one light guide comprises a face opposite to said projection surface, said opposite face comprising distribution means for distributing the light along said projection surface. It is understood that the light guide is made in a single piece having both the projection surface and the opposing face which is opposite, which reduces the number of parts and reduce the cost of manufacture while maintaining a good light concentration efficiency. According to the various embodiments of the invention, the treatment head is designed to provide care by illumination and / or mechanical action (massage). [11] Advantageously, said distribution means comprise at least one surface (51, S2) at least partially reflecting for reflecting a portion of the light towards said projection surface. The at least partially reflecting surface is part of the opposite face and allows at least a portion of the projected light to be reflected, the reflection occurring within the light guide. [12] In order to define its geometrical shape, said at least one light guide has at least one cross section (S) of passage of light which is a section passing through a plane (P) perpendicular to said projection surface, said transverse section (S) intersecting with the projection surface and said at least one surface (51) respectively along a first straight line (D1) and a second straight line (D2). Thus, said at least one light source is arranged at one end of said cross section (S) between the first straight line (D1) and the second straight line (D2). Thus, the light passes through a wall of the light guide arranged between the projection surface and the opposite face. [14] According to a variant of the light guide, the absolute distance between the first line (D1) and the second straight line (D2) is constant from the end where said at least one light source is arranged. This represents a light guide in the form of a substantially planar plate. According to another variant of the light guide, the absolute distance between the first line (D1) and the second line (D2) decreases from the end where said at least one light source is arranged. The reflective surfaces are then arranged successively on a slope, each surface receiving at least a portion of the light emitted by reducing the cross section to the right of each surface as one moves away from the light source. [16] In addition, said distribution means comprise at least two at least partially reflecting surfaces (Si, S2), one of said two surfaces (S2) and said cross section (S) being intersecting along a third straight line (D3), the distance between D1 and D2 being greater than that between D1 and D3. Such a passage section corresponds to a light guide having grooves in the form of regular grooves on the opposite face. This makes it possible to reinforce the reflection of the light and to reduce the refraction at the level of the opposite face. An even more homogeneous diffusion of the light along the projection surface is obtained. According to a first embodiment of the apparatus, said light guide is a solid of revolution of said cross section around a central axis (A). The light guide then has a circular shape. [181] Advantageously, the opposite face has splines starting from said central axis (A). This makes it possible to reinforce the reflection of the light and to reduce the refraction at the level of the opposite face. The light beams are well distributed on the circular projection surface, especially the areas between two adjacent light sources. Alternatively, the opposite face has hollows in the shape of a half-sphere, for example as a golf ball or the like. This makes it possible to vary the macroscopic reflection angle of the light beams and to homogenize them. [20] In addition, said opposite face is at least partially covered with a white layer. Or alternatively, said opposite face is at least partially covered with a metallized color layer. This makes it possible to reinforce the reflection and to reduce the refraction at the level of the opposite face. [21] Advantageously, said projection surface has diffusing means such as graining, for example of the chemical or horn type. This accentuates the diffusion of light and makes it possible to further homogenize the beams on the skin. [22] Advantageously, said at least one light source is a light emitting diode (LED), because such a light source is both intense and compact and can therefore simultaneously optimize the efficiency and size of the device. [23] According to a second embodiment of the apparatus, said at least one care head comprises mechanical massage means intended to come into contact with the skin and means for actuating said massage means actuated by an electric motor which is connected to said power supply means. The implementation of such mechanical massage can bring a stimulation of the blood circulation in the skin of the face. The cells are all the more activated by the phototherapy treatment simultaneously applied to the massage. [24] According to a first variant of the second embodiment, said massage means comprise at least one massage ball intended to be displaced in rotation along at least one vertical axis of rotation which is perpendicular to the projection surface. [25] According to this variant, said light guide has at least one through hole passing said massage ball. Thus, it is possible to combine care by illumination with care by mechanical action while keeping the compactness of the device. [26] Thus, said light source comprises a plurality of light-emitting diodes evenly distributed around said light guide for homogeneous distribution of light. [27] According to a second variant of the second embodiment, said massage means comprise a support member intended to come against the face and two massage fingers intended to come into contact with the skin alternately. [28] According to this variant, said light guide is arranged near said support element and substantially parallel thereto. [29] Thus, said light source comprises at least one light emitting diode between said massage fingers and the body. According to a third variant of the second embodiment, said massage means comprise two massage rollers which are rotatable about themselves in two horizontal axes of rotation (B1, B2) parallel to each other and each perpendicular to the axis of the body, a first roller comprising at least one radially extending pallet projecting from the surface of the first roller and the second roller having a smooth surface, said rollers being actuated by operating means . [31] According to this variant, the apparatus comprises at least one light guide intended to cover at least one contact zone (Z) at the end of the rollers intended to come into contact with the skin. Thus, said light source comprises at least one light-emitting diode near said contact zone (Z). [33] According to a fourth variant of the second embodiment, said massage means comprise two cylindrical rollers which are rotatable on themselves according to two axes of rotation (C1, C2) parallel to each other and to the axis from the body. [34] According to this variant, the apparatus comprises at least one light guide intended to cover at least a first lighting zone (Z ') at one end of the cylindrical rollers and / or a second lighting zone (Z ") located between said cylindrical rollers, said first lighting zone (Z ') being intended to come into contact with the skin. [35] Thus, said light source comprises at least one light-emitting diode in the vicinity of said first zone [36] Advantageously, said massage means are transparent or translucent so as to allow transmission of light. [37] In addition, said at least one care head is detachable from said body and The apparatus comprises at least two different interchangeable care heads on the body [38] The invention will be better understood from the study of the embodiments taken as non-limiting and illustrated by the appended drawings in which: FIG. 1 illustrates a view of a first embodiment of the apparatus according to the invention; FIG. 2 illustrates a view of the treatment head according to the first embodiment; FIG.

In a second variant, FIGS. 21 and 22 illustrate views of the second embodiment of the apparatus, according to a third variant. FIGS. 23 to 25 illustrate views of the second embodiment of FIG. According to a fourth variant, FIG. 26 illustrates a view of the light guide according to the third variant of the second embodiment of the apparatus. FIG. 27 illustrates a view of the light guide according to the fourth variant of FIG. second embodiment of the apparatus. [39] As illustrated in FIG. 1, the invention relates to a skincare apparatus 1 comprising a body 2 of longitudinal shape and a central axis (A) comprising a housing consisting of two half-housings 21, 22 together forming a gripping area. A care head 3 is mounted on one end of the body having a treatment zone (ZT) for operating on or near the skin. Said treatment zone (ZT) may be a light projection zone and / or an area having mechanical massage means according to the embodiments. The care device 1 also comprises, inside the body 2, power supply means 23 as can be seen in FIG. 15, for example a rechargeable battery. The invention will be described in two parts with - a first part relating to the first embodiment of the apparatus devoid of mechanical massage means, which is illustrated in Figures 1 to 13; a second part relating to the second embodiment of the apparatus in its various variants, the second embodiment comprising mechanical massage means which are illustrated in FIGS. 14 to 27. Part I [40] As illustrated in FIGS. Figures 2 and 3, the care head 3 has a substantially cylindrical shape of central axis (A) and comprises a plurality of light sources 4 which are LEDs arranged inside the cylinder. According to the illustrated example, the LEDs 4 are six in number and are distributed evenly around the cylinder. The LEDs 4 are powered by the power supply means 23 by means of electrical wires (not shown) so that each LED is oriented towards the center of the cylinder and projects light beams in this direction. As regards the positioning of the LEDs 4, the treatment head 3 comprises a ring 30 having circumferential cavities in which the LEDs are embedded, said ring 30 being transparent, translucent or opaque.
    [0002] The crown 30 also aims to conceal the LEDs so that they are protected from the outside. [41] The care head 3 comprises inside a light guide 5 which aims to orient and homogenize and focus the light beams from the LEDs to the skin. To do this, said light guide 5 has a substantially circular and one-piece plate shape having a smooth outer surface which is a projection surface 51 of the light. Said projection surface 51 defines the treatment zone (ZT) which is intended to come close to the skin or against the skin. The light guide 5 also has an opposite face 52 which is arranged facing said projection surface 51 and spaced therefrom by a substantially cylindrical side wall 55 visible in FIG. 4. The LEDs are therefore distributed around the guide of FIG. light 5 facing the side wall 55. [42 1 Said opposite face 52 comprises distribution means 53 for distributing the light along the projection surface 51. According to a first variant of said distribution means 53, it is a smooth and reflective surface S2 as visible in FIG. 3 intended to receive the light beams coming from the LEDs and to reflect them towards the projection surface 51. In order to better schematize this, one could imagine a cross section (S) of passing light towards the center which is obtained by the intersection of a plane (P) perpendicular to said projection surface 51, the light guide 5 and the central axis (A). As illustrated in FIG. 10, the cross-section (S) and the projection surface 51 are intersecting along a first line D1; the cross section (S) and the opposite face 52 are intersecting along a second line D2. The distance between D1 and D2 is constant from the end where the LED is arranged. The light guide 5 according to this variant is a solid of revolution of said cross section (S) around the central axis (A). [431 The distribution means 53 could also take other different forms which are illustrated in FIGS. 4 to 9. According to this second variant, the distribution means 53 comprise a series of reflective surfaces presented in the form of streaks on the opposite face 52 [44] According to a first variant of the grooves, the distribution means 53 have on the opposite face 52 concentric hollow circles 56 for guiding the light beams through the entire cross section (S) to the center of the light guide 5 in order to have a homogeneous distribution of light on the projection surface 51. In this variant, the second straight line D2 representing the non-hollow portion of the opposite face 52 is discontinuous. The cross-section (S) and the light guide 5 are intersecting along a third discontinuous line D3 representing the hollow part of the opposite face 52, the distance between D1 and D2 being greater than the distance between D1 and D3. FIG. 12 shows the cross section (S) constituting the hollow circles 56 by revolution around the central axis (A), the variants of the light guide 5 having such circles are illustrated in FIG. 6. [45] According to a second variant of the streaks, the distribution means 53 have on the opposite face splines 57 in radii from the central axis (A) to the side wall 55 to distribute the lights on the projection surface 51 between two adjacent LEDs, as shown in Figure 4. [46] The concentric hollow circles 56 and the spoke grooves 57 could be combined to provide a better distribution of light. Such a combination makes it possible to vary the macroscopic reflection angle of the light beams and to homogenize them. An example of the light guide 5 combining the two distribution means is illustrated in FIG. 5. [47] Still according to the example of the circular plate, the distribution means 53 can also comprise a conical surface hollowed towards the inside of the plate. . According to the variants in which the distribution means 53 are a smooth surface or a surface having splines 57, the opposite face forms a slope such as can be seen in FIG. 11 so that the entire surface is biased to reflect some of the light emitted . According to the variant in which the dispensing means comprise hollow circles 56, the distance between D1 and D2 is decreasing from the end of the light guide 5 towards the central axis (A) as can be seen in FIG. The light according to this variant is illustrated in FIG. 9. Thus, each streak is urged by the light beams to return them to the projection surface 51. The conical shape of the opposite face makes it possible to better reflect and distribute the light beams towards the skin. to achieve better light efficiency through higher overall intensity. Of course, the light guide having such a conical shape on the opposite face could only have splines 57 as shown in FIG. 8, or both types of ridges as can be seen in FIG. 7. [48] The light guide 5 can be made of plastic material of PC type (polycarbonate), PET (polyethylene terephthalate) colorless, SAN (styrene-acrylonitrile) or thermoplastic PMMA (Poly methyl methacrylate) which has a good environmental index, a good reflection to interfaces and good transparency for less energy absorption and therefore less losses. Other materials could also be considered, for example glass. [49] In order to mask the interior of the light guide and to make the projection of the light beam as homogeneous as possible, the projection surface 51 may be frosted or grained, for example with a graining of the chemical or birch type.
    [0003] PART II [50] We will now describe the second embodiment of the invention, in which the apparatus comprises massage means 31, 32, 33, 34, 35, 36, 37, 37 ', 38, 39, 39 'according to four variants as illustrated in FIGS. 14 to 27. [51] In the second embodiment, each treatment head 6, 7, 8, 9 comprises means for adapting the treatment head 6, 7 , 8, 9 on the body 2 removably, said matching means 61, 71, 81, 91 being formed by a sheath allowing the care head 6, 7, 8, 9 to be partly engaged in the body 2. The body 2 comprises an electric motor 24 connected to an output shaft 25 by transmission means, the output shaft 25 being accessible at the end of the adaptation means 61, 71, 81, 91 The electric motor 24 is controlled by a control unit connected to a manual control interface accessible from outside the body 2. The control interface manu it may for example include an on-off switch and / or manual selection means of operating programs. [52] The care head 9 according to the first variant as illustrated in Figures 14 to 18, has a substantially cylindrical shape coaxial with the body 2 of the apparatus. The treatment head 9 comprises a bearing ring 30 delimiting a working zone inside which there are three massage beads 31, 32, 33 projecting from the plane of the ring 30, as illustrated in FIG. In the illustrated example, each massage ball has a contact surface that is deformable to properly train the skin with the movement of the balls. For example, the ball may be at least partially silicone for a soft and hanging effect. As illustrated in FIG. 15, each massage ball 31, 32, 33 is connected to actuating means to be rotated not only with respect to the central axis (A) but also with respect to a vertical axis of rotation. Ai, A2, A3 which is its own. To do this, the operating means comprise a trainer 26 intended to fit with the output shaft 25 of the motor for its setting in motion. For example, the driver 26 may have a cross-shaped cavity for receiving the output shaft 25 by a protuberance of the same shape thereon. The shaft trainer 26 (A) carries on an upper face three pins (not shown) each engaged in an axial bore of a sun gear 31 ', 32', 33 '. Each massage ball is fixed on the corresponding planetary gear. Each planet gear meshes with the toothed periphery 301 of a fixed ring 50, illustrated in FIG. 17, so that the rotation of the trainer 26 causes the planetary movement of the massage balls 31, 32, 33, that is to say say a main rotational movement of the three balls around the central axis (A) combined with a secondary rotational movement of each of the balls around the vertical axis of rotation Ai, A2, A3 which rotates around the central axis (A) during operation of the device. As illustrated in FIGS. 16 and 17, the treatment head 9 comprises a series of LEDs arranged around the periphery of the ring 30 as in the first embodiment. The light guide 5 according to this variant is arranged between the bearing ring 30 and the fixed ring 50. As visible in Figure 18, the light guide 5 has through holes 541, 542, 543 for passing the massage ball 31, 32, 33. The light guide 5 is rotated by the movement of the balls. [54] The skincare head 9 according to this first variant makes it possible to knead the skin of the face, in particular the wide areas such as the cheeks or the forehead, to activate the microcirculation and to stimulate the natural mechanisms of production of the structuring proteins of the skin. and thus prevent the signs of age. These effects are accentuated by the presence of light on the skin. [55] The care head 6 according to a second variant as illustrated in Figures 19 and 20 is designed to perform a tapping massage. For this purpose, the care head 6 comprises a support element 34 which is intended to come against the face to define a working distance. Thus, the support element 34 defines a bearing surface (SA) which forms a reference surface. The bearing surface (SA) is ideally smooth and it can have a concave shape that allows it to marry the conformation of the cheekbones when the massage is performed under the eyes or around the eyes. [56] The treatment head 6 comprises above the bearing surface (SA) and opposite the body 2 with respect to said bearing surface (SA), massage fingers 35, 36 which comprise each a working head intended to come into contact with the face. The two massage fingers 35, 36 are each movable between, on the one hand, a retraction position corresponding to the position of the massage finger 36 located in the foreground in FIG. 19 and, on the other hand, a position of extension corresponding to the position of the massage finger 35 located in the background in the same figure. In the retracted position, the working head of each massage finger 35, 36 is located below the bearing surface (SA) towards the inside of the treatment head 6. While in the extended position, the working head of each massage finger 35, 36 is beyond the bearing surface (SA) towards the outside of the treatment head 6. Each working head then has between its retraction positions and extension, a displacement amplitude of between 5 mm and 15 mm. Furthermore, in the extended position each working head is protruding relative to the bearing surface (SA) by a distance of between 2 mm and 10 mm. [57] The treatment head 6 also comprises operating means 34 ', 35', 36 'adapted to move alternately each of the massage fingers 35, 36 between its extension and retraction positions. The operating means 34 ', 35', 36 'are then adapted to cooperate with the output shaft so as to transmit and transform the rotational movement of the electric motor 24 into an alternating movement of the massage fingers 35, 36. [58] According to the illustrated example, each massage finger 35, 36 is in the form of a kind of straight piston which extends at least partly outside a hollow body 63 surrounding the means operating mechanism 34 ', 35', 36 '. Each finger is then guided in translation by a bore 64 formed in the hollow body 63. The end of each massage finger 35, 36 located inside the hollow body 63 cooperates with an eccentric pin (not shown) carried by a operating disk 35 ', 36' belonging to the operating means.
    [0004] The eccentric pin is disposed in a chamber 65 which is rigidly connected to the corresponding massage finger and in which the eccentric pin can move in translation so that its rotation with the operating disk 35 ', 36' is transformed into a translation of the massage finger 35, 36 corresponding. [59] One could very well imagine other embodiments of the care head 6 tapping, such as a connecting rod-crank system or a cam drive tilting the massage fingers alternately about an axis . [60] As illustrated in FIG. 19, the treatment head 6 according to the second variant comprises at least one LED 4 in the hollow body 63 and at one end of the support element 34 so that the light beams leave towards the opposite end. The treatment head 6 then comprises in the hollow body 63 a substantially rectangular light guide 5 which corresponds substantially to the bearing surface (SA). The LED is therefore arranged at the end of the light guide 5 facing a side wall 55 thereof. The projection surface 51 is close to the bearing surface (SA) and the opposite face 52 may be parallel to the projection surface 51 or may approach the projection surface 51 progressively from the end where the LED is present. 4. [61] In order to illuminate the skin, the support element 34 is transparent or translucent to pass light. [62] Such a means of massage allows, by the tapping provided by the massage fingers, to stimulate blood circulation around the eyes to reduce dark circles and puffiness. The massage device can also be used to revive the metabolism, in particular the production of the constitutive elements of the skin, and thus treat fine lines and wrinkles of the face, especially in the nasolabial fold, by stimulating blood circulation. slowed by the wrinkling of the skin at the level of wrinkles. These effects are accentuated by the presence of light on the skin. [63] The treatment head 7 according to the third variant as illustrated in FIGS. 21 and 22 is designed to perform a nip massage. For this purpose, the treatment head 7 comprises, as massage means, two massage rollers 37, 38 which are rotatable about themselves according to two horizontal axes of rotation B1 and B2 parallel to each other and perpendicular to each other. central axis (A) as best seen in Figure 21. The two massage rollers 37, 38 are spaced apart from each other by being separated by a working area.
    [0005] According to the illustrated example, the distance between the horizontal axes of rotation B1 and B2 is constant. [64] Furthermore, according to the illustrated example, the massage rollers 37, 38 are arranged within the treatment head 7 so that a plane tangential to the two rollers and located towards the outside of the treatment head 7 forms with a longitudinal axis of the body 2 a non-zero angle and different from the right angle. [65] According to the invention, a first roll 37 comprises at least one pallet 37 ', and in the present case represented by way of example four pallets which extend radially projecting from the surface of the first roll 37. The care head 7 has on either side of the rollers 37, 38 a contact zone (Z) intended to bear against the skin for the maintenance of the apparatus on the skin during the treatment. The peripheral surface of the first roll 37 is then set back from the contact zone (Z). The pallets 37 'have a radial extension sufficient to protrude from the contact zone (Z) as the first roll 37 is rotated. The pallets 37' are further evenly distributed around the periphery of the first roll 37 and are, in the present case, placed at 90 ° from each other. [66] According to the illustrated example, the pallets 37 'have transverse cross sections of different shapes, it being understood that all the pallets could have the same shape. Thus, the pallet 37 'has, seen in cross section, an "8" shape. Other pallet shapes are also conceivable, such as a pallet which has, seen in transverse cross section, a free end thicker than the rest, or a pallet which has, seen in transverse cross section, a straight shape, or finally, a pallet which has, in cross section, an elongated and tapered shape whose thickness is reduced towards the end. [67] The second roller 38 has a smooth-type peripheral surface that protrudes from the contact area (Z) or extends to the side of the contact area (Z). [68] According to the invention, the treatment head 7 also comprises operating means 38 'adapted to drive the rollers 37 and 38 in the same direction, from the outside of the working area to the inside of the work area for the first roll 37, and from the inside to the outside of the work area for the second roll, seen from outside the care head and as indicated by the arrows F1 and F2 on FIG. 22. The operating means 38 'are then adapted to cooperate with the output shaft 25 so as to transmit and transform the rotational movement of the electric motor along the central axis (A) in rotational movements according to the axes B1 and B2 which have a direction orthogonal to that of the central axis (A). [69] According to the example illustrated in FIG. 22, the operating means 38 'comprise a gear train 38' comprising, first of all, two frustoconical gears providing a bevel gear and, subsequently, spur gears. providing driving together but at different speeds of the massage rollers 37 and 38. The operating means 38 'are preferably adapted to provide a rotational speed of the first roll 37 greater than that of the second roll 38 and in the case present triple that of the second roller 38. [701 Furthermore according to this variant, the treatment head 7 comprises LEDs near the contact zones (Z). Several arrangements of the LEDs could be envisaged since the contact zones (Z) are each covered by a light guide 5. In the example illustrated, two LEDs are arranged at the top of the treatment head 7, that is, that is to say at the end of the contact zones (Z) remote from the body 2; two other LEDs are arranged at the bottom of the care head 7, that is to say at the other end of the contact zones (Z). The light is then transmitted by the light guide 5 which is shown in FIG. 26. The light guide according to this example has a one-piece shell shape of substantially constant thickness and conforming to the shape of the contact zone (Z). One could also consider an arrangement of the LEDs in the middle of the contact areas (Z) to enhance the illumination between the two rollers. The light guide could then have a thickness in the middle greater than that at its ends. [71] Such a massaging means massage the skin by slight pinching so as to reproduce a "pinch Jacquet" type massage performed by aesthetic professionals with thumb and index in a delicate manner. These effects are accentuated by the presence of light on the skin.
    [0006] The treatment head 8 according to the fourth variant as illustrated in FIGS. 23 to 25 is designed to provide a "palpate-roll" type massage on the skin in order to obtain a remodeling effect. Such a treatment head 8 comprises a roller chamber 83 having an application surface (Z ') intended to bear against the skin and two cylindrical rollers 39, 39', a portion of which extends beyond the application surface (Z '). These cylindrical rollers 39, 39 'are arranged along two axes C1, C2 parallel to each other and relative to the central axis (A). As visible in FIG. 24, the treatment head 8 comprises operating means 26 'comprising a disc rotated by the output shaft 25, the disc being rotatably connected to a toothed wheel. The operating means 26 'further comprise a gear train connecting the toothed wheel to two gears rotatably connected respectively to each of the two cylindrical rollers 39, 39' and intended to drive them. [72] According to the invention and as illustrated in FIGS. 23 and 25, the treatment head 8 further comprises LEDs 4 arranged at one end of the cylindrical rollers 39, 39 ', preferably at the proximal end to the body 2 of the device. To better project the light coming from the LEDs, the treatment head 8 is equipped with a light guide 5 presented in the form of a one-piece shell having an "I" shape seen from the front. The light guide 5 then comprises at least a first part covering said application surface (Z ') to form a first lighting zone (Z') and a second part covering a surface at the bottom of the roller chamber 83, in particular between the two cylindrical rollers 39, 39 'to form a second lighting zone (Z ") The light guide 5 according to this example is illustrated in FIG. 27. [73] Such a massage means makes it possible to optimize the work of the skin by pleating in a complete, pleasant and effective way.These effects are accentuated by the presence of light on the skin. [74] In order to better transmit light to the skin, the means of 31, 32, 33, 35, 36, 37, 37 ', 38, 39 and 39' can be transparent or translucent [75] According to the illustrated examples, the LEDs are integrated in the treatment head 6, 7, 8 , 9 having a massage function to be closer to the skin.
    [0007] However, it is quite possible to arrange the LEDs in the body 2 of the device, at the end where is mounted each care head 6, 7, 8, 9. Thus, the electrical connections are simplified which allows to make the device more secure, economical and compact. Of course, the invention is not limited to the described and illustrated embodiments which have been given by way of example only. Modifications are possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
