Axillary odor is commonly known as “fox odor”, because the sweat glands are affected by endocrine secretion during adolescence, so fox odor mostly begins in adolescence. Bacteria in the armpit and the organic matter contained in the secretions of the sweat glands interact to produce saturated fatty acids, resulting in odor. Some patients have a clinical family history of fox odor, so fox odor is related to genetics. In addition, climate change, hormonal malfunction during growth and development, fatigue, etc. are also triggers for the onset of axillary smell. Everyone has sweat glands, why only some people get axillary odor, and it occurs more in young women? This is because there are individual differences in the degree of development and function of the sweat glands, and those with particularly well-developed sweat glands and strong secretion functions are prone to axillary sniffing. Young women have more sweat glands than men, so there are more cases of armpit sniffing in women, especially around menstruation and during pregnancy, when the odor is stronger. Axillary smell (fox odor) patients are mostly young boys and girls psychological development age, axillary smell without timely treatment will cause psychological burden, serious people suffer from mental illness. The armpit smell (fox odor) can actually be cured, once the symptoms are found to be timely treatment. There are various treatment methods for axillary odor, and the efficacy varies. The mechanism of treatment is based on two aspects: removal of sweat glands and blocking the excretion of secretions. If the above two problems can be solved, then satisfactory results can be achieved. 1, non-surgical treatment: including a variety of topical applicators, the use of simple, short-lived effect. There is a stimulating effect on the skin, which can cause skin roughness, pigmentation, etc. 2.Botulinum toxin method: Local injection with a certain amount of botulinum toxin can be a quick and convenient non-invasive and painless treatment for axillary sniffing, which does not affect work and has become the preferred treatment for axillary sniffing. 3.Surgical excision: The effect is remarkable, but it requires hospitalization, long postoperative scars, and affects arm lifting, so it has been eliminated. 4.Laser hair removal and closed sweat glands: The treatment time is short, ten minutes, no hospitalization, does not affect the daily work and life, but requires multiple treatments, usually once every two months, often need to treat four to five times. Sometimes it will leave a dotted scar, which affects the beauty. 5.Minimally invasive surgery (incision of 2-3 cm): the first choice for one-time radical treatment. Because of its good effect, almost no scar after surgery, does not affect the appearance of the axillary skin and upper limb activities, without hospitalization, and become a better choice for the majority of seekers. Based on years of clinical experience, a minimally invasive surgical approach is applied to make a small incision in the patient’s armpit to completely remove the deep dermis and superficial subcutaneous sweat glands and hair follicles from underneath the skin in the area of axillary hair to eliminate the root cause of axillary smell. Since the incision is made in the transverse axillary line, the scar is not very conspicuous after the surgery and is one of the most popular options in recent years.
