What is Hyperhidrosis?

Hyperhidrosis is a common condition characterized by excessive sweating affecting up to 4.8% of the general population1. Studies show that hyperhidrosis has a severe impact on the quality of life of its sufferer, affecting their social life, well-being, and emotional and mental health. Its impacts can even be greater than other dermatological conditions, such as severe acne or psoriasis.
Despite these effects, most hyperhidrosis sufferers rarely talk about their condition to a health professional. Hyperhidrosis is thus referred to as the ‘Silent Handicap’.

Why choose Dermadry?

Dermadry is a trusted solution showcased on the International Hyperhidrosis Society's website. Dermadry offers a solution for people who suffer from palmar (hands), plantar (feet) and axillary (underarms) hyperhidrosis that is needle-free and drug-free. Its products are designed to treat specific customer needs, whether an individual sweats only from their hands and feet, only from their underarms or from all three areas.
Dermadry’s advanced technology distinguishes itself through its affordability, intuitive use and the quality of its components. It’s also the only tap water iontophoresis machine that has received a medical device license by Health Canada.
Dermadry is indicated for the treatment of people of at least 13-years-old suffering from moderate to severe axillary, palmar and/or plantar hyperhidrosis (excessive sweating of the underarms, hands and/or feet).

How it works

Dermadry is a tap water iontophoresis device. This technology works by directing a small current through the skin, 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%2, 98.5%3 and even 100%4 of patients treated for hyperhidrosis.

One of the simplest, safest, and most cost-effective treatments of hyperhidrosis.5


Tap water iontophoresis treatments need to be repeated to maintain dryness. The use of tap water ensures uniform treatment over the targeted areas. Providing an adequate level of current on the targeted area will stop sweat in most cases. The success of treatment depends on the current strength. Higher current strengths work better and should be used for intense sweating. The treatment strength should be changed based on skin sensitivity. Hands and feet can tolerate a higher current strength than underarms.

Scientific Evidence

The effectiveness of tap water iontophoresis to treat hyperhidrosis has been demonstrated by numerous studies. These studies were performed on patients with primary focal hyperhidrosis (mild, moderate and severe). The studies were performed on patients in all age ranges from 8 years old to 71 years old.
The treatment parameters were mostly similar regarding the current strength, the treatment duration and the treatment frequency.
The clinical studies evaluated the efficiency of the treatment both in clinical conditions (in hospital, performed by healthcare professionals) and at home (patients were provided with devices and performed treatments on their own).

Here’s what they say:
  • Tap water iontophoresis treatments improve the patient’s quality of life significantly during treatment.6
  • 92.9% of patients saw results after two weeks of iontophoresis treatments.7
  • 88.9% of patients had positive results, and a majority of the patients found the maintenance program compatible with their lifestyle.8
  • Quality of life improved in 78.6% of patients after 2 weeks.9
  • Tap water iontophoresis is a simple, safe and effective therapeutic option for palmoplantar hyperhidrosis.10
  • Tap water iontophoresis is a safe and effective treatment for both palmoplantar (hands and feet) hyperhidrosis and axillary (underarms) hyperhidrosis in the pediatric population, with minimal side effects.11
  • Tap water iontophoresis is an effective method of treatment for primary palmoplantar (hands and feet) and axillary (underarms) hyperhidrosis in pediatric patients.12
  • The study demonstrates that tap water iontophoresis controls palmar (hands) hyperhidrosis after a total of eight treatments.13
  • Iontophoresis treatment is safe, effective, and easy to use for the treatment of palmar and plantar hyperhidrosis. This technique should be offered to patients with palmoplantar hyperhidrosis prior to surgical intervention or toxin injection.14
  • Tap water iontophoresis suppresses palmar hyperhidrosis. When instructions are followed, tap water iontophoresis is safe for unsupervised treatment of hyperhidrosis. Iontophoresis is a simple, economic and effective therapy that should be offered to patients for control of palmar hyperhidrosis prior to surgical intervention. Iontophoresis is also a suitable alternative to long-term drug therapy. The study demonstrated a success rate of 83.3%.15
  • At present, tap water iontophoresis represents the most effective therapy in hyperhidrosis of palms or soles. Patients with extremely high sweat rates respond to the treatment, no adverse effects were noticed during long-term maintenance treatment, and tap water iontophoresis not only curbs sweating, but also abates other uncomfortable symptoms, such as lividity, edema and clamminess of palms and soles.16
  • We found the treatment to be so effective in axillary (underarms) hyperhidrosis that we would recommend iontophoresisin preference to surgical excision of the sweat-glands.17
  • In our view, tap water iontophoresis is by far more successful in treating hyperhidrosis of palms and soles. In a group of 7 patients, complete relief from excessive sweating was achieved and no treatment failure was observed.18
  • Since 1968, tap water iontophoresis has been employed as the method of choice for treating palmoplantar hyperhidrosis.19
  • In 2014, an FDA panel reviewing scientific data on the matter concluded that “all 8 studies reported that tap water iontophoresis effectively reduced sweating in the majority of subjects treated with [tap water iontophoresis]”.20
