Hyperhidrosis, a medical condition characterized by excessive sweating, results from overactive sweat glands. Severe underarm sweating, a form of hyperhidrosis, can significantly impact an individual’s daily life. Fortunately, BOTOX has gained FDA approval as an effective treatment for severe underarm sweating. By blocking the nerve signals that trigger sweating, BOTOX injections can reduce excessive sweating and improve the quality of life for those affected by this condition.
