What is the Science Behind Dermadry?

Dermadry is a tap-water iontophoresis device. It works by applying a small electrical current to the skin, which helps to disrupt the connection between the nerves and sweat glands. By doing so, it effectively reduces excessive sweating in the majority of cases.

This method involves immersing the affected areas, such as the hand or feet, in trays filled with tap water. The Dermadry device then delivers a mild electrical current through the water, which is conducted through the skin. The electrical current helps to block the sweat glands, preventing them from producing excessive sweat. It also interrupts the signals between the nerves and sweat glands, reducing the stimulation that leads to sweating. The tap water used in the treatment serves as a conductor for the electrical current, ensuring its effective delivery to the affected areas.

Dermadry is designed to be safe and easy to use. 

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 the devices can reach 93%¹, 98,5%² and even 100%³ of people treated for hyperhidrosis.
