It is common in areas where sweating, sweat does not evaporate easily and sweat glands are located, such as the armpits, groin, feet, perianal area, vulva, umbilicus and under the female breast, etc., with foot and axillary odor being the most common. Foot oedema is often accompanied by excessive sweating of the feet, with a pungent odor, which is obvious in summer. Hand and foot odor, excessive sweating can be improved by applying Botox injections. However, the hands and feet are more sensitive to pain, there is a certain amount of pain when injected, and it is not very common to have injection treatment for excessive sweating of the hands and feet in clinical practice. Axillary odor receives the most attention. The two main types of improvement methods commonly used today are non-surgical and surgical. Non-surgical treatment, from the simplest can be purchased from the pharmacy to cover the odor or inhibit the secretion of sweat glands to reduce the symptoms of some spray or smear of drugs. Of course, this can feel a bit cumbersome when repeated daily. In this case, botulinum toxin injection can be applied to inhibit sweat gland secretion to improve. The maintenance time of one injection is about six months. For places where the seasons are distinct, one injection can sometimes be enough for a summer in peace. There are also some photoelectric technology treatments, such as laser treatment, radiofrequency treatment, these are still relatively obvious for mild to moderate patients to improve, need about 1-3 times of treatment. For moderate to severe patients, surgery is still recommended. The method of direct skin excision of the sweat gland area is thorough, but the scarring is obvious, and the skin excision is limited by the pulling activity, this method has been abandoned for 20 years. The most popular methods are scraping and suction and small incisions to remove sweat glands under direct vision. The former is easy to perform and has a quick recovery. The latter requires a longer dressing and slower recovery, while the latter is more thorough. However, both methods are more effective. The scraping and suction method is more recommended.
