This condition can affect people regardless of the weather or physical activity and may cause visible sweat patches, frequent clothing changes, embarrassment, and a significant impact on confidence, work, social interactions, and quality of life. For many individuals, even prescription-strength antiperspirants provide little or no relief.

Botulinum toxin is a highly effective, evidence-based treatment for axillary hyperhidrosis. It works by temporarily blocking the release of acetylcholine, the chemical messenger that stimulates the eccrine sweat glands. Without this nerve signal, the treated sweat glands produce little or no sweat, while the body's normal ability to regulate temperature remains unaffected because untreated sweat glands elsewhere continue to function normally.
