The academic name for acne pits is acne scarring. Acne scarring can be eliminated through fruit acid peels, physical therapy, and hyaluronic acid injections. 1. Fruit acid peeling: using a certain concentration of fruit acid, the thickened epidermal stratum corneum and part of the shallow dermis can be properly peeled off, which can reduce the height of the thickened tissue around the original acne pits, and at the same time, it can also promote the proliferation of collagen fibers and elastin fibers in the dermis layer of the depressed tissues inside the acne pits, so as to make the pimples eliminated. 2. Physical treatment: for example, laser dermabrasion treatment, mainly using fractional laser, repeated peeling between the epidermis and dermis, and local grinding to eliminate pimples. 3. Hyaluronic acid injection: For deeper acne pits, hyaluronic acid injection can be used to make the depressed part of the skin bulge and keep level with the surrounding skin tissue. However, the effect of injection can only be maintained for a period of time, and multiple injections are needed to maintain the efficacy. It is recommended that patients should go to the dermatology department of the hospital in time for medical treatment, and do not treat them on their own, so as not to affect the aesthetics or complications when they are not treated properly.
