2. Injection method. The injection is mainly aimed at hypertrophic scars. Injecting drugs for removing acne marks into skin surface cells through syringes can play an antibacterial and anti-inflammatory role. In the process of treatment, inflammatory tissue is dissolved and digested, and non-inflammatory tissue is protected, thus achieving therapeutic effect. This method can smooth acne marks, but there is no way to fade them.
3. Fruit acid method. For sunken skin, friends with shallow acne marks will be helpful. In the process of treatment, high concentration of fruit acid is used to peel off the cuticle of the skin, which plays a role in metabolism, so that new cells are rapidly updated and dead cells fall off. Fruit acid method can improve the problem of coarse pores, but it also needs multiple treatments to achieve the effect of complete elimination.
