Botulinum toxin treatment for armpit odor generally requires multiple injections of Botulinum toxin in the distribution area of axillary hair on both sides, and the number of injections is generally 20 to 40 points/side, and the number of injections is related to the size of the distribution range of the individual’s armpit hair, so the specific number of injections can not be generalized. Armpit odor is a disease in which the secretions of the sweat glands in the armpits are decomposed by bacteria and produce an unpleasant odor. Typically, Botox for armpit odor requires multiple injections in the distribution of armpit hair bilaterally, with 20 to 40 injections per side. This method can inhibit the secretion of axillary parietal sweat gland glands, so as to achieve the effect of deodorization. However, due to the different conditions and treatment effects of individuals, some patients who do not have obvious effects or have serious conditions need 2 weeks of observation time, and then follow the doctor’s instructions to decide whether additional injections are needed. Those with obvious effect can generally reach 5~7 months, maintaining the effect needs to be injected again. For people who need to take Botox to treat armpit odor, it is recommended to go to a regular hospital to consult a doctor, according to the individual situation, under the guidance of the doctor to formulate a treatment plan, and cooperate with the doctor for standardized treatment.
