Abstract
A method and apparatus for applying iontophoretic treatment to a living body is provided by which a unidirectional treatment current is periodically interrupted by a relatively short pulse of current in the opposite direction in order to prevent the formation of undesirable vesicles and bulla in the skin being treated. The apparatus and method are arranged to impose the treatment current gradually at the beginning of each treatment.
