By utilizing direct current (DC) iontophoretic treatment on electrodes with high impedance we show the effectiveness of iontophoresis as a driving force for permeation of ionic electrolyte into the skin barrier. After a 60 second DC treatment at 50μA or 100μA amplitudes on either saline, Nihon Kohden Elefix, or Agar based electrolytes we saw an immediate impedance drop ranging from 3-30%. The effects generally lasted several hours.
