Generating cold plasma away from skin, and associated systems and methods

A device for treating human keratinous material, in particular with the aid of an electric current. The device includes a reservoir containing a composition, in particular cosmetic or dermatological, to be applied to the keratinous material, and an end fitting for the application of the composition contained in the reservoir, the end fitting comprising a plurality of application members and a distributor. The distributor includes at least one storage cavity for the composition and supply orifices to conduct the composition from the storage cavity or cavities to the application members, and the distributor being configured so that the flow rate of the composition arriving at the application members is identical to within 20% for at least two application members, better for each application member.

A iontophoresis method () is described for delivering vitamin C through the skin of a biological subject, the method comprising applying () 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.
