Have you ever noticed that celebrities don't sweat? Even if they're parading down a red carpet in sweltering heat, you won't see a hint of underarm moisture. Their secret? Botox for sweating.
Many celebrities reportedly have Botox injected into their armpits before events. That's because Botox can curb even the most excessive sweating, AKA hyperhidrosis. Here's a rundown on how you can use Botox for excessive sweating.
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.
The FDA has since approved using Botox for underarm sweating. According to the Botox website, Botox injections can reduce the amount of underarm sweat produced by more than half, with really noticeable improvement during the first four weeks.
Note: Some doctors use Botox “off-label” on excessively sweaty palms and feet, though according to the manufacturer, it is not known if Botox is safe or effective for sweating anywhere other than your armpits.
The manufacturer recommends using Botox for sweating if you 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.
However, some people do use the injections to treat less serious cases of sweating (ahem, celebs).
During an appointment, the doctor generally administers 10–15 injections to each underarm. But don't worry, the needle is pretty fine.
Results can last for nearly seven months—that's about three to four months longer than the results last with Botox for wrinkles.
Yes, of course. Sweat is how your body regulates temperature. However, people with hyperhidrosis have overactive sweat glands, and their sweating significantly exceeds the body’s normal requirement for cooling.
Plus, your body has as many as 4 million sweat glands. There will still be plenty of healthy sweating going on.
According to the manufacturer, you must be at least 18 years old and experience severe underarm sweating that won’t respond to topical medicines. Only a doctor can determine this.
