Sweaty hands are often the most visible area affected. Iontophoresis can be used to control Palmer Hyperhidrosis (excessive sweating of the hands). Simply perform a series of 20 minute sessions over a couple of weeks. Then enjoy a period of no-sweating, which can last for weeks.
The feet are another area of the body where excessive sweating is often a problem. Again, iontophoresis is proven to be exceptionally effective in controlling Plantar Hyperhidrosis. This can also help with secondary skin conditions such as Athletes Foot.
