Embodiment Construction

[0103] figure 2 and image 3 A device 1 according to the invention with an X-axis is shown. The device comprises a body 12 on which is mounted an end piece 6 defining a flat application surface 5 . The single-dose container 3 of the composition is housed in the body 12 in contact with the applicator end-piece 6 .

[0104] In the example discussed, body 12 may be made of a thermoplastic material. As a variant, the body can be made of any other material. The applicator end piece 6 may have any other shape, for example the shape of a roller. The applicator tip can be press fit, snap on or screw onto the body 12 .

[0105] The device 1 comprises an electrode 10 housed between a body 12 and an end piece 6 , and also comprises a counter electrode 5 arranged on the body 12 . When the user holds the device 1 with his hand, the counter electrode 15 is in contact with the user's hand, so that the electrical circuit between the electrode 10 and the counter electrode 15 is closed b...

Abstract

The invention relates to a device (1) for cosmetically treating human keratin materials with the aid of an electric current, comprising at least: a power supply system, an electrode (10) and a counterelectrode (15), a reservoir (3) containing a cosmetic composition, the reservoir being provided with at least one outlet orifice (4) for the composition, an application end piece (6) that is fed withcomposition from the reservoir (3), the reservoir (3) being at least partially defined by a first, electrically conductive zone (1) and by a second, elastically deformable zone (2).

Description

technical field [0001] The invention relates to a device for the cosmetic treatment of keratin materials. [0002] More generally, a cosmetic product is a product as defined in Regulation (EC) No 1223 / 2009 of the European Parliament and of the Council of 30 November 2009 on cosmetic products. [0003] The invention relates in particular to devices for the treatment of keratinous materials by means of electric currents. [0004] expression " human keratin material " is understood to mean primarily the skin, especially the skin of the body or face, or the scalp, nails or hair. Background technique [0005] It is known that the application of electrical current to the skin can facilitate the penetration of active agents. Thus, it is known to treat human keratin materials by means of iontophoresis devices. Iontophoresis allows the diffusion of active agents across the skin by electrical stimulation in a non-invasive manner. The strength and polarity (anodic or cathodic) of ...
