While there are many different treatments available, some that work and some that don’t, Botox has proven to be the most effective for underarm sweating. With the use of botulinum toxin type A, these injections block the chemical in the body that stimulates sweat glands.
Typically, each armpit will receive 25 injections, and it requires only one session to see results. Many patients notice significantly decreased sweating within the same week of treatment. Ultimately, patients see a decrease by about 82% to 87%.
Results last anywhere from four to six months before repeated treatment is necessary, making it highly effective, easier, and less risky or invasive than other treatments.
