Axillary odor, commonly known as “fox odor,” is an unpleasant odor that emanates from the armpits bilaterally and is thought to be related to the breakdown of the secretions of the parietal sweat glands (macrosomia) by surface bacteria to produce unsaturated fatty acids. There are many ways to treat armpit odor, including antiperspirant application, botulinum toxin injection, and surgical treatment. The following is a brief introduction to the advantages and disadvantages of various methods, armpit odor troubled friends can choose the treatment method according to their own situation. 1, topical antiperspirant. There are many anti-sweat products available on the market, which can be applied to the armpits after each bath. The advantage is that it is simple and non-invasive, but the disadvantage is that it needs to be used repeatedly, regardless of home travel, antiperspirant can not leave the body, or the embarrassing smell will reappear in the next bath or a lot of sweating. For mild armpit odor, not yet determined to use a more thorough treatment method friends can use this method. 2.Injecting botulinum toxin. Botulinum toxin is a long history of biological toxin. 1817 first described the clinical symptoms of food-borne botulinum toxin poisoning, 20s Dr. Scott will be applied to the treatment of strabismus, eye muscle spasm, 1987 Canadian ophthalmologists will be introduced to the field of cosmetology to achieve satisfactory results, 1989 U.S. Food and Drug Administration approved botulinum toxin for clinical treatment drugs. Since then, the annual growth rate of botulinum toxin injection for cosmetic treatment is as high as 142%. Botox can not only remove wrinkles and slim the face, but also inhibit sweat and treat armpit odor. The advantages are that the treatment is simple, does not interfere with work, there are no complications and side effects as long as the regular product is used, and the treatment takes up to 6-8 months to eliminate armpit odor. The disadvantage is that the treatment needs to be repeated every 6-8 months. For those who are worried about the complications of surgery and have some financial means can use this method. 3.Surgical treatment. The traditional surgery is to remove all the hair from the armpits, which is a thorough treatment, but the damage is too great. Nowadays, the surgery only removes the sweat glands in the armpits. In order to achieve this, many methods have been developed, such as opening a small 2-3mm opening and scraping the sweat glands with a straw or using a scraping spoon to scrape out the sweat glands, or opening a 4cm incision to completely separate the skin from the subcutaneous tissue and then turning out the inner layer of the skin to cut off the sweat glands. The advantage of these methods compared to the old full skin incision is that it is less traumatic and there are no obvious marks after surgery, but the disadvantage is that the shoulders need to be strictly braked for 3-5 days after surgery, which is rather sad, and there may be complications of surgery, such as subcutaneous hematoma, skin infection, skin necrosis, incomplete removal of axillary odor or recurrence. For those who want to get rid of the problem once and for all and are over 18 years old, they can consider surgical treatment.
