Abstract: A iontophoresis method (700) is described for delivering vitamin C through the skin of a biological subject, the method comprising applying (702) a selected current profile, either continuous direct current or pulsed current or a combination of both to a biological subject. A iontophoresis composition is further described, comprising one or more of vitamin C, vitamin C derivatives, ions of vitamin C and ions of vitamin C derivatives and further comprising a silicon material and water. A iontophoresis kit for carrying out the iontophoresis method is also disclosed. The application further describes a iontophoresis device comprising an electrode assembly and circuitry configured to concurrently generate a continuous direct current stimulus and a pulsed current stimulus; a corresponding iontophoresis method for delivering a cosmetic composition to a biological subject is also disclosed.

Abstract: A cosmetic treatment process for a keratin material, including placing the keratin material in contact with at least one cationic polymer with a molecular weight of between 500 and 5,000,000 daltons, and either simultaneously with or consecutively to the placing the keratin material in contact with said cationic polymer, an electric current is applied using at least one electrode for a time that is sufficient to deposit at the surface of the keratin material an effective amount of said cationic polymer.

Abstract: A device for the cosmetic treatment of keratin materials with an electric current, including: a current generator (1), a reservoir (3) containing a cosmetic composition (P), an end piece (2) comprising an electrode (4) and at least one applicator member (6, 7), said applicator member (6, 7) delimiting an outer wall (61, 71) that is able to be filled with product contained in the reservoir (3), a counter electrode (5), a system for regulating the quantity of composition (P) exiting the reservoir (3) on the basis of the impedance measured between the electrode (4) and the keratin materials, the electrode (4) and the applicator member (6, 7) being designed such that the composition (P) is the only conductive substance in contact with the skin while the device is being used.
