Hyperhidrosis (Excessive Sweating )
Research indicates that treating excessive sweating of the underarms, hands, feet, head and face, with BTX-A is safe and effective. When used to treat underarm excessive sweating, Botox® has been shown to result in an 82-87% decrease in sweating. Results start to be noticeable approximately 2 to 4 days after treatment with the full effects usually noted within 2 weeks. Dryness typically lasts 4 to 12 months but some studies have found it can last as long as 14 months. Additional research have shown that repeated treatment with Botox® is safe and effective for hyperhidrosis and consistently results in meaningful, long-lasting improvements in an excessive sweating patient’s symptoms, daily functioning, and quality of life.
While sweating is an essential body function for temperature-control, localized body areas house only a small percentage of the body’s sweat glands (the underarms, for instance, are home to less than 2% of the body’s sweat glands.) The temporary cessation of these sweat glands’ functioning, therefore, has little to do with body thermoregulation.
