How Long It Takes for Botox to Stop Underarm Sweating

Do you find yourself constantly changing shirts or avoiding certain fabrics because of underarm sweat? Excessive sweating can impact your confidence, wardrobe, and daily comfort. If deodorants and antiperspirants haven’t worked, Botox might be the solution you didn’t know you needed.

Dr. Elizabeth Callahan at SkinSmart Dermatology is double board-certified in Dermatology and Mohs Micrographic Surgery. She is nationally recognized as a top injector and has achieved Platinum Level status with Allergan, the maker of Botox. Patients travel from across Florida and the country to benefit from her expertise in treating both cosmetic and general dermatological concerns.

How Botox Helps With Underarm Sweat

Botox works by temporarily blocking the nerve signals that activate sweat glands. When used to treat hyperhidrosis (excessive sweating), Botox is injected directly into the underarm area. This disrupts the chemical messages sent to the sweat glands, reducing perspiration.

According to the International Hyperhidrosis Society, Botox can reduce underarm sweating by up to 87% in treated patients. Most people begin to notice a decrease in sweat production within three to five days.

When to Expect Results From Botox

While results are not immediate, they are often noticeable within the first week after treatment. Maximum results typically appear around 10 to 14 days post-injection.

You can expect:

• Initial improvement within a few days: You may start to notice a reduction in sweat production as early as three to five days after treatment. The treated area begins responding to Botox as it starts to interrupt the signals that activate sweat glands.
• Peak results within two weeks: Around 10 to 14 days post-injection, Botox reaches its full effect. At this point, sweat glands are fully suppressed in the targeted area, and dryness is typically at its highest.
• Long-lasting dryness: Results often last between six and eight months, with many patients experiencing consistently drier skin throughout that period. Over time, repeat treatments can help extend results and maintain comfort with fewer sessions.

With consistent treatments, many people enjoy long-term relief and greater confidence in their daily lives.
