A Dermatologist Weighs In on 3 Treatments That Can Stop Excessive Sweating

Botox can be injected into the underarm area to alleviate sweating. "Botox works by blocking the neurotransmitters that stimulate the sweat glands," Bhanusali said. The treatment is temporary, and you would have to repeat it every four months.

During a Miradry session, your underarms get blasted with thermal energy (and cooled simultaneously), which the brand says "safely destroys" your sweat glands. First, a template of where the tool will be placed is temporarily inked onto the skin. Then, your doctor will hold a device that administers that energy against the area, lining it up with the template.

"It tends to be the most permanent solution to underarm sweat," Bhanusali said. "Many patients first try topicals, orals, and Botox before realizing they want to take care of it once and for all." However, Miradry can also prove painful. "The treatment takes 15-20 minutes and can definitely feel intense at times, but we usually inject localizing anesthetic and now offer things like Pronox (nitrous gas) so the patient tends to feel minimal discomfort," he said.
