Iontophoresis
Iontophoresis has been used to treat uncontrollable, excessive sweating on the hands and feet since the 1940s. It's particularly useful for people who've tried prescription or clinical strength antiperspirants, but have found that they need a stronger treatment.
For people with hyperhidrosis (excessive sweating) of the hands and/or feet, iontophoresis treatments can dramatically improve the condition. One study found that iontophoresis helped 91% of patients with excessive palmoplantar (hands and feet) sweating. Another study showed that iontophoresis reduced sweating by 81%.
During iontophoresis, a medical device is used to pass a mild electrical current through water (usually utilising shallow pans big enough for your hands or feet) and through the skin's surface. There are no significant or serious side effects and the benefits are long-term, provided you keep up with the maintenance schedule your doctor recommends (usually once per week).
