Underarm odor is because the sweat glands in the armpit are more developed, and the underarm skin is fermented by bacteria in a moist environment, which can be removed by injection treatment, surgical excision, and underarm scraping. 1. Injection treatment: Botulinum toxin is injected into the armpit to inhibit the release of acetylcholine, resulting in a gradual decrease in the secretion of sweat by the sweat glands in the armpit, thus reducing the production of odor and achieving the effect of removing odor. 2. Surgical excision: After anesthesia, part of the sweat glands in the armpits are surgically excised to reduce the sweat in the armpits, which can remove the odor. 3. Armpit scraping: localized in the armpit with “armpit odor scraping and sucking needle” on the armpit sweat glands for scraping and sucking, part of the sweat glands will be removed from the skin, to remove the purpose of odor. Underarm odor, should pay attention to light diet, keep personal hygiene and clean, and go to the hospital in time to choose the appropriate treatment.
