Iontophoresis is an effective treatment of sweating to the hands or feet. It can be used for armpits, but the results are not as good.

Iontophoresis was originally described in the 1950's, but its exact mode of action remains uncertain.

Iontophoresis sounds worse than it is!

It involves submerging the hands or feet in a bowel of water with a wet contact pad applied to the armpits. A weak electric current is passed through the water. It is thought that minerals in the water in some way blocks the sweat glands. The treatment is generally not painful but the small electric current can cause some mild, short-lived discomfort and skin irritation.

Each session of Iontophoresis lasts between 20 and 30 minutes with treatments normally occurring two to four sessions per week. Improvement after 4 to 10 sessions is expected, after which further treatment is required at one to four-week intervals, depending on the severity of your symptoms.

Iontophoresis has proved to be effective in 80 to 90% of cases, but is time consuming and requires regular visits to a hospital or dermatology clinic to receive treatment. For a small number of patient, it does cause significant pain.


Home use Iontophoresis kits are available with prices ranging from £325 to £500.
