Hyperhidrosis, more commonly known as excessive sweating, can significantly affect a person’s quality of life. In some cases, problematic sweating is limited to one area of the body, such as the underarms or feet, a condition called focal hyperhidrosis. Other cases are more generalized, with sweating over large areas of the body. The most common areas affected by hyperhidrosis are the scalp, underarms, hands, feet and groin area.
Botox—often associated with cosmetic wrinkle reduction—is also a particularly effective treatment for focal hyperhidrosis. Botox injections use botulinum toxin to block the nerve signals responsible for sweating, stopping the sweat glands from producing too much sweat. Retreatment is typically needed in four to six months, as the nerves regenerate. Over time, however, patients can go longer between treatments.
