Abstract
This invention relates to a transcutaneous iontophoresis device, particularly intended to activate penetration into the skin (P) of a cosmetic preparation applied to the skin, this device comprising at least two electrodes (11, 12) raised to different electrical potentials by an electricity generator (2), and the first electrode (11) being shaped such that it can be moved on the skin (P). According to the invention, the second electrode (12) is shaped so that it can be moved about on the skin (P) at the same time as the first electrode (11) and the two electrodes (11, 12) are separated from each other by a non-zero distance (D) equal to not more than 20 centimetres.
