Excessive sweating, or hyperhidrosis, can significantly cause discomfort and self-consciousness for those affected. The use of Botox injections to treat excessive armpit sweat has become increasingly popular in recent years. Botox, a purified form of botulinum toxin, is commonly known for its cosmetic applications, but it has also proven to be highly effective in controlling excessive sweating.

The injection of Botox inhibits the release of acetylcholine, a neurotransmitter that stimulates sweat glands. Botox effectively reduces sweat production in the treated area by inhibiting this chemical signal. This treatment is suitable for individuals who suffer from excessive underarm sweating and have not found relief through traditional antiperspirants or medications. Patients typically see a significant reduction in sweating within 2-7 days after the injections, with the full effect visible in about two weeks. Results last anywhere from 3-6 months, depending on individual factors, after which the treatment can be repeated.
