Iontophoresis Treatments

Iontophoresis refers to the use of electrical current on the surface of the skin. Iontophoresis is used for a variety of skin treatments, but is primarily used to treat excessive sweating. The process is painless, though some individuals may find the tingling sensation caused by iontophoresis to be uncomfortable.

Treating Hyperhidrosis with Iontophoresis

Excessive sweating, or hyperhidrosis, is a medical condition that causes excessive and unpredictable sweating. Iontophoresis works with water to provide mild electrical current to the skin. It is thought that the current causes the skin to thicken microscopically, which blocks sweat from being able to reach the surface of the skin. With the output of sweat blocked, the glands responsible for producing sweat will stop production.

The process requires a patient to submerge his hands and/or feet in shallow pans of water for 20 to 40 minutes, while a device provides mild electrical current to the water. The water conducts the current to the surface of the skin, where it stimulates the surface of the skin.

The American Academy of Dermatology (see Resources) recommends the use of iontophoresis in the treatment of sweaty hands and feet. Treatments must be repeated to maintain desirable results, and a prescription is required to administer the treatment at home.

Side Effects

Iontophoresis is effective in reducing sweat output from the palms of hands and feet, but there are some side effects you should be aware of. Irritation of abrasions, cuts and hang nails are a possibility, and the International Hyperhidrosis Society reports that excessive dryness of the skin can occur. Cover any abrasions, cuts and hang nails with Vaseline before treatment, and use Vaseline and 1% hydrocortisone creams to protect and soothe dry skin.
