It is a very strong chemically corrosive substance that can strongly corrode the skin and the diseased tissue. The actual use of the product is not only not good for observing the effect, but also may lead to local inflammation and ulceration, which may lead to scar formation later on, so it is usually recommended to use it once every five days. In the process of use, attention must be paid to the cosmetic consequences of prolonged corrosion, especially for scar patients, who must use it with caution.
In daily life, attention needs to be paid to a light diet and regular rest and relaxation to promote a speedy recovery.
