What is Iontophoresis

Iontophoresis is the application of direct current.
It can be used to introduce substances through the skin, but in the treatment of hyperhidrosis, the current alone is what is effective. This current is applied through the submersion in water. The result with several treatments is a reduction in excessive sweating. This is thought to be caused by a plugging of the sweat pores.

What is Hyperhidrosis

Hyperhidrosis is a condition whereby the body produces sweat beyond what is necessary to maintain a normal body temperature. When this condition affects the hands or feet it is called palmer or plantar hyperhidrosis. People affected by this problem suffer social embarrassment and may be limited in some occupations where damp hands may soil or damage products. (ie. paper, metal, electrical components) Hyperhidrosis affects approximately 3% of the population.

What are the treatment options for hyperhidrosis?

Possible treatment options are as follows:

  1.  Topical treatments: the application of aluminum chloride hexahydrate has been shown in clinical studies to reduce swearing by approximately 50% for mild hyperhidrosis sufferers.
  2.  Iontophoresis: iontophoresis is appropriate for people who suffer from hyperhidrosis affecting the hands or feet. This application is not recommended for underarm or head/facial hyperhidrosis.
  3.  Botulinum toxin type A: Botox injections are appropriate for moderate to severe hyperhidrosis sufferers.Injection is done into the affected area and is effective for as long as the nerve to the sweat glad is deadened. Percentage reduction in sweating using this method was reported to be 83% in 95% of people studied. The average duration of effect is 7 months until symptoms recur.
  4. Surgery: this is a last resort for people whose lifestyles are seriously affected by hyperhidrosis and for whom other more conservative methods have failed.

In order to find the best treatment for you, speak to your dermatologist.
