Hyperhidrosis, or excessive sweating, typically involves the axilla (underarms), palms of the hands, soles of the feet, the groin, and the face. When medicines used on the skin (topical) do not work well enough injectable neurotoxins are a popular treatment option.
The treatment consists of injections into the specific areas where the sweating occurs. The toxin blocks nerve signals to the sweat glands thus reducing sweat production. Results typically last 3-6 months.
