The so-called armpit odor, commonly known as fox odor, is a special unpleasant odor emitted by the decomposition of secretions from the sweat glands that are distributed on the skin of the body such as the armpits, by the bacteria that grow in the armpits. In other words, the reason why armpit odor occurs, and the body’s sweat gland secretion function is abnormal. Because the pungent smell of armpit odor makes people feel particularly unbearable, most of those who smell this odor cover their noses and stay away, causing embarrassment to the person concerned. Some even cause a great psychological burden, thus affecting work, study, romance, and social relations. People with armpit odor often have to shower, change clothes, and even pay attention to diet, which brings a lot of inconvenience to their lives. The conventional treatment for armpit odor is surgical excision, but since only large sweat glands can be removed. Small sweat glands cannot be completely removed, so it is easy to repeat. Even if the surgery is still simple, you still have to consider some problems after the surgery, such as prevention of infection, always pay attention to no strenuous exercise, poor wound healing, postoperative scarring, etc. According to scientific experiments published in the American Journal of Dermatology, Botox can effectively solve the problem of armpit odor. The human sweat glands are innervated by cholinergic nerves, and when Botox is injected into the sweat glands, it can act on the cholinergic nerve endings to weaken the secretion of the sweat glands, thus treating armpit odor. The process of botulinum toxin treatment for armpit odor begins with the doctor preparing the medication, marking the area around the armpit for injection, and then injecting according to the marked injection site. There is no need for anesthesia when injecting Botox, and after the injection, gentle pressure on the armpit is sufficient for a few minutes. After Botox injection, you can take a shower the next day, and you can see the effect in three days. It is less invasive and less painful, and it takes 3-6 months to “refresh” through the summer. It is a good choice for those who do not want to suffer the pain of surgery and want to reduce armpit odor.
