The technique is iontophoresis, which has now been used by medics as a non-invasive drug delivery method for medication since the 1960s. It no longer used a continuous wave of galvanic current but modulated it into impulses. This lowered the incidence of burns whilst disappointingly also lowering the amount of active ingredients which could be carried, but as the wave frequency was not altered the levels of skin penetration remained very much the same as with ionophoresis.
