摘要

Skin treatment device comprises a housing (10) conveniently a plastics moulding, contains a low-tension D.C. power circuit including a battery (21), the negative pole being connected through a flexible lead (20) to a probe (16) having a metal electrode tip (22) for application to a localised area of the user's skin requiring treatment. The tip is conical terminating at an acute point and having an included angle of taper of preferably around 50 deg. for non-invasive application to the skin. The positive pole is connected to a second electrode (26) constituted by a portion of the housing which will be gripped in the user's hand completing the operative circuit through the user's body.
