ABSTRACT:
Disclosed is a novel therapeutic device comprising means for generating a low-frequency current in which an undirectional current is superposed on a dc current; means for switching at time intervals the output polarity of said oscillating means; an electrode means which contains an ionized medicament and acts as the active electrode; and another electrode means which acts as the dispersive electrode. A high efficacy that is hardly attainable by iontophoresing either cation or anion is possible by allowing the whole of an ionized medicament such as aminovinyl photosensitizing dye or kojic acid to penetrate into the deeper part of the skin with the device of the invention.
