How does botox work for hyperhidrosis sufferers?
A. Botox works by blocking the chemical signal from the nerve to the target tissue, which in the case of hyperhidrosis is the sweat gland. As the sweat gland is no longer stimulated by the overactive nerve, the sweating stops. Since the drug only works in the area it is injected, sweat glands in other parts of the body function normally. There is no risk of getting overheated.
