Botulinum toxin (known as Botox) is a drug that temporarily paralyzes muscles to treat certain muscle conditions, reduce wrinkles or stop sweat.
Botox has become a widely recognized treatment for axillary hyperhidrosis (excessive underarm sweating), gaining the FDA’s stamp of approval in 2004. To treat severe underarm sweating, Botox works by blocking the secretion of the chemical that activates sweat glands. During the procedure, doctors (typically dermatologists) inject around 50 units of Botox into each armpit. The more units injected, the longer the drying effects tend to last.
Overall, the procedure is relatively quick and painless — except when it comes to your wallet.
Every body breaks down Botox differently so the duration of the results will vary. Typically, you will experience dry armpits for around 3 to 6 months after receiving Botox injections. However, exercise and stress can accelerate the body’s metabolic response to Botox so the results fade faster.
