There are three main treatments for axillary odor: Botox, CO2 laser and minimally invasive surgery. There is a lot of confusion about the choice of methods. Which method is effective and suitable? First of all, you should have an understanding and determination of your condition. The degree of axillary odor is determined by the following criteria: mild for repeatedly wiping the skin of the armpit with a sterile dry swab, the doctor, the patient and the people nearby can smell a pungent odor on this swab; moderate for O.3 m, and smell a pungent odor on the patient. Today we will mainly talk about laser treatment of armpit odor. The principle is that the laser beam directly makes the hair follicle and surrounding tissue and sweat gland vaporization and coagulation, degeneration necrosis, sweat gland body atrophy, duct closure, so that the sweat gland loss of function, to achieve the purpose of treatment. This method is easy to operate, short surgery time, light trauma, no bleeding, less patient pain, fast recovery, because the damage to the skin and the normal skin and subcutaneous tissue in the area of surgery intact, can make the damage to the skin quickly repair, without scarring. However, because it cannot destroy all the sweat glands, the cure rate is not high at one time and often requires multiple treatments, especially for some patients with severe symptoms. For patients with mild symptoms or those who cannot take a long time off work and have a fear of surgery, laser treatment is an option.
