Excessive sweating, or hyperhidrosis, affects millions of people worldwide. For those living with it, the condition is more than a physical issue: it affects confidence, daily comfort, and social interactions.
Until recently, professional treatments for hyperhidrosis were mainly available through dermatology clinics. But today, with innovations like Dermadry, you can manage excessive sweating safely, effectively, and conveniently at home.
What Is Tap Water Iontophoresis?
Tap Water iontophoresis is a time-tested, non-invasive treatment that uses a gentle electrical current to temporarily block the connection between your nerves and sweat glands. It’s used as a first-line or second-line treatment for hyperhidrosis of the hands, feet, and underarms.
During a session, the affected area is immersed in shallow trays or covered with soaked pads filled with tap water. The mild current passes through the skin, reducing the activity of sweat glands and providing lasting dryness.
This treatment has been used in medical settings since around the 1940s and is recognized by dermatologists worldwide as one of the most effective methods to treat palmar (hands), plantar (feet), and axillary (underarm) hyperhidrosis.
Dermadry has taken this trusted technology and designed it for safe, at-home use.
How does Dermadry work?
Dermadry’s iontophoresis device is a compact, medical-grade system composed of a control unit, electrodes, and treatment trays or pads. The process is simple and comfortable:
-
Set up the device and connect the control unit with the electrodes and trays.
-
Fill the trays or soak the pads with tap water.
-
Choose the treatment area (hands, feet, or underarms) and adjust the current level based on your comfort.
-
Press down on the activation button and hold for three seconds to start the treatment.
-
Place your hands/feet in the tray or place the underarm pads under your arms, and relax for 15–20 minutes as the treatment reduces your sweating.
Treatment is divided into two phases: the initial phase and the maintenance phase. For the initial phase, users are recommended to do five daily sessions per week, with two days allotted for rest to give the skin time to recover. This frequency of treatment is continued until you achieve your desired dryness. Typically, the initial phase lasts for two weeks, but it can last up to six weeks for severe cases.
Once dryness is achieved, users can transition to the maintenance phase. You can reduce the number of sessions, usually 2-3 per week. It’s important to test what maintenance schedule works for you, so gradually reduce the number of sessions instead of immediately dropping it to one. With maintenance, you can keep your dryness as long as you want.
Dermadry’s design makes it easy to incorporate into your routine. With consistent use, most users experience sweat-free comfort and reclaim their control and confidence.
