Frequently Asked Questions

Do your hands drip with sweat? Are your socks always soaked? Hyperhidrosis is a medical condition that causes abnormal sweating not related to exercise or another underlying condition. While it can affect different areas of the body, the most common cases involve the hands, feet, and/or underarms. Besides being a physical medical condition, hyperhidrosis can often cause social anxiety and occupational difficulties that severly limit an individual’s quality of life. Our Treatment Specialists can share some truly inspiring success stories of people – both young and old – whose lives have been changed after discovering our iontophoresis device.

Iontophoresis is an at-home treatment for managing sweat from hyperhidrosis. The treatment introduces ions into the body through the skin by applying a mild electric current. For hyperhidrosis patients, iontophoresis uses the natural minerals found in tap water to “plug” the sweat pores, creating a long-lasting dryness barrier.

Treatment session times vary between 15 – 20-minutes. On average, patients see significantly drier results within 2-weeks.

Iontophoresis has been clinically-proven to reduce sweat since the 1950s. Modern studies by Dr. Fred Levit and Dr. Lewis P. Stolman have continued to demonstrate the efficacy of iontophoresis for treating hyperhidrosis.
