Dermadry is a tap water iontophoresis device. This solution works by directing a small current through the skin, thus neutralizing the connections between the sweat nerves and sweat glands. For the vast majority of cases, this treatment drastically reduces excessive sweating.
Studies have shown that tap-water iontophoresis devices such as Dermadry are extremely effective in the treatment of excessive sweating. These studies report that the success rates of these devices can reach 93%1, 98.5%2 and even 100%3 of people treated for hyperhidrosis.
“One of the simplest, safest, and most cost-effective treatments of hyperhidrosis.“4

Tingling and stinging sensations. Muscle numbness (paresthesia) may occur. Slight pain could be felt at the beginning of the treatment or after the polarity alternating sequence. If you feel any of the above side effects, reduce intensity during next treatment.
Increased sweating: After the first few treatments, you may experience an increase in sweating. This symptom will subside after a few treatments.
Small electric shocks during treatment: In very rare cases, a harmless electric shock may occur if treatment is interrupted suddenly. To avoid this risk, remove your hands, feet or underarm electrodes slowly. Hands, feet and underarms electrodes can be safely removed at any time during treatment.
Skin dryness: Skin may become dry, small lesions or scaling may occur. To reduce these symptoms, use a moisturizing cream after treatments.
