The Condition
What is Hyperhidrosis
(Excessive Sweating)
Hyperhidrosis is a medical condition characterized by excessive sweating that affects 4.8%1 of the population. Those who suffer from the condition sweat 4-5 times more than the average person, largely exceeding what is needed for body temperature regulation.
The condition is linked to a decreased quality of life and can have negative effects on an affected individual’s occupational, physical, emotional, and social life. A lack of awareness combined with the fear of embarrassment leads many to suffer in silence, which is why it is often referred to as “the silent handicap”.

The Solution
The science behind Dermadry's iontophoresis machine
Dermadry is a home-use tap water iontophoresis machine. This technology works by directing a small current through the skin, effectively neutralizing the connection between the nerves and the sweat glands. In nearly all cases, this effectively treats excessive sweating!

Studies have shown that iontophoresis machines such as Dermadry are very effective in the treatment of excessive sweating. These studies show that success rates can reach 93%1, 98.5%2 and even 100%3 of people treated for hyperhidrosis!
