Botox ForExcessive Sweating (Hyperhidrosis)

Hyperhidrosis is more than “sweating a lot". For some people, it’s persistent, localised sweating that happens even when you’re not overheated or exercising, and it can be difficult to control with standard antiperspirants. Because it sits somewhere between a medical issue and a quality-of-life concern, it’s easy to feel unsure about what’s normal, what’s treatable, and which options are actually evidence-based. 

Botulinum toxin injections are one of the better-known clinical options for focal hyperhidrosis, especially underarm sweating. They work by blocking nerve signals that trigger sweat glands in the treated area (they do not suppress sweating across the whole body). Effects are temporary, and response, longevity, and practicality vary depending on the area treated and the individual. 

In this guide, you’ll learn how the treatment is performed in a typical clinic setting, which areas may be considered, what a realistic timeframe looks like for onset and duration, and how to think about risks, aftercare, and repeat appointments. We’ll also cover where this sits alongside other treatments, and what to ask in a consultation so you can make a calm, informed decision.
