Acne scarring is classified as patchy, mild, moderate and severe. Patchy refers to obvious discoloration that is neither prominent nor atrophic, and the discoloration can appear as either erythema, hyperpigmentation or hypopigmentation; mild acne scarring: refers to scarring that is not recognizable beyond 50cm and does not impede social activities. These scars are easily concealed by makeup; moderate acne scars: clearly visible at a distance of 50 cm, either atrophic or hyperplastic scars If the scar is atrophic, it can be flattened when the skin is stretched. These scars are easily visible and not well concealed by makeup, so they may cause social and psychological barriers to patients; severe acne scars: clearly visible at a distance of 50 cm and not concealed by makeup. Severe acne scars can be clearly seen from 50cm away and cannot be concealed by any kind of makeup, which can be extremely damaging to the patient’s psychology.
Treatment for patchy acne scars: Topical medication or superficial chemical peeling can be chosen.
Treatment of mild acne scarring: For patients with less scarring, atrophic scarring can be treated with collagen, hyaluronic acid filler injections, and for patients with more scarring, grinding treatment can be chosen first.
Treatment of moderate acne scarring: If there is less scarring, local injection treatment of scarring or subcutaneous peeling can be chosen Severe acne atrophic scarring, especially depressed and ice pick type scarring needs to be excised, usually by ring drilling, and if necessary, cosmetic surgery with reduction sutures can be implemented. If the atrophic scar is too extensive, it will manifest as localized facial atrophy. Implementing fat grafting filler injections while dealing with the scar is a good way to restore the overall appearance For severe hyperplastic scars, hormonal local seal treatment can be considered, and surgical methods are used to treat the few relatively isolated lesions when necessary.
