Traditional methods of removing sweat duct tumor are freezing and high-frequency ionization, which are invasive treatment methods, painful, red, swollen and blistered during treatment, sometimes needing anesthetic injections, which can easily cause eye damage to the eyes and is very unsafe, and it is also difficult to control the treatment depth of the skin layer, which can easily damage the neurovascular layer of the dermis and produce permanent scars. Treatment. Corrosive chemicals such as sulfuric acid, hydrochloric acid, carbolic acid, sodium hydroxide, lime and other strong acid and alkaline dangerous chemicals have a strong corrosive effect on human skin, and once they get on the skin, they will immediately penetrate the epidermis and dermis of the skin and even reach the periosteum layer, burning the skin muscles and neurovascular tissues and causing permanent damage scars, so they should not be used to get rid of sweat duct tumors.
