Abstract: A skin treatment device, adapted for delivery of an active ingredient into the human skin by means of iontophoresis, the device having electrodes to establish an electric field on the human skin, wherein the device includes an array of n electrodes with at least a first and a second electrode.

Abstract: A skin treatment device includes a substrate and a plurality of discrete galvanic couples provided on the substrate, each discrete galvanic couple including a first conductive electrode that is an anode and a second conductive electrode that is a cathode, wherein the anode of each galvanic couple includes a first metal and the cathode of each discrete galvanic couple includes a second metal, different from the first metal, the first and second metal having a different standard potential.

Abstract: An adhesive polymer matrix for the delivery of an active principle via iontophoresis. The matrix having a first face intended to be applied onto skin and a second face intended to cooperate with electrodes. The matrix comprises electrically conductive zones and at least one electrically insulating zone, each conductive zone being insulated from another conductive zone by an insulating zone. The techniques involve the use of an electric current in order to facilitate the transdermal diffusion of active substances, and relates more particularly to an iontophoresis device.

Abstract: The invention concerns an electrostimulation and/or iontophoresis device comprising a patch (10) suitable for application to a user's skin (12) and a voltage generator (22) suitable for applying a low intensity current through the user's skin by a system of electrodes located in said patch; This device is characterized in that it comprises a self-regulator (16) that varies the voltage supplied by the voltage generator as a function of the continuous measurement of the resistivity of the user's skin beneath said patch The resistance value of the skin provided by an element for measuring the resistance of the skin (24) yields the resistivity measurement.
