Botox Is Sweat’s Number-One Enemy

It’s no secret that Phoenix is hot—after all, the city is named after a bird that continually bursts into flame. USA Today named it America’s fifth hottest city, while ranked it among the world’s 16 hottest. So it’s hardly surprising that in Phoenix, Botox is regularly sought out for its ability to reduce perspiration.

Many people already know that you can use Botox under eyes to eliminate crow’s-feet or between the brows for frown lines. But in recent years, more and more medical professionals have turned to Botox for sweating. Here’s a rundown of how it works, what to expect during an appointment, and how long it can keep you dry.

Shutting down sweat

Back in 1993, two physicians researching the treatment of facial spasms discovered one of the more interesting side effects of Botox—it minimized sweating. When injected into the dermis, the layer of skin where sweat glands, hair follicles, and nerve endings are found, Botox attaches to nerve endings, interrupting signals from the nervous system that activate sweat glands. It’s most effective in areas with more hair follicles; that’s why it’s predominantly used on underarms. (Though some doctors do recommend it for palms and feet, too.)

How big is the needle?

Don’t worry, it’s pretty fine. During an appointment, the doctor generally administers 10–15 injections to each underarm. According to the Botox website, treatments can reduce sweating by more than half, with really noticeable improvement during the first four weeks. Results can last for nearly seven months.

Just how sweaty do I need to be for this?

Botox for excessive sweating is recommended for people aged 18 or older who haven’t found relief from over-the-counter or prescription antiperspirants. Other indicators include having to change clothes multiple times a day due to sweating or keeping towels or deodorants on hand to manage perspiration.

But wait—doesn’t my body need to sweat?

Yes, of course. But your body has as many as 4 million sweat glands. There will still be plenty of healthy sweating going on.
