An indicator for the electrophoretic deposition of a medicament through or on a skin surface. The device includes layers forming a reservoir containing the drug, a battery layer superimposed on the reservoir, and a cover of electrically conductive material fully enclosing the layers and having a lip along its periphery to electro-conductively engage the skin surface and form an electrical circuit.
