Acne pits are caused by infection and inflammation or external compression. Due to the lack of timely and appropriate treatment during the acne period, the inflammation of skin cells leads to local necrosis and liquefaction of skin tissue, resulting in a defect in the subcutaneous tissue, which produces pits, or scar proliferation, leaving a convex scar. It can be repaired by medical means, even if the pits are more than ten years old. What type of pimple pit do you have? What is the best method to repair them? The common method for acne scars used to be grinding, but it has been abandoned because mechanical grinding is so damaging and microdermabrasion is too weak. The safer and more effective weapons now are Plasma and fractional laser. However, the situation of acne scars is very different, some people have increased collagen tissue, some people have destroyed collagen tissue, and it is difficult for a single photoelectric treatment to fit everyone’s acne scar problem, therefore, the treatment effect is still unsatisfactory. After years of clinical practice and research, we have concluded a comprehensive treatment method for different types of acne scars. The following is a brief introduction combined with pictures. Classification of acne scars: Ⅰ Ice pick type Treatment: Peel off and let the adhesions between the scar and the subcutaneous loosen, followed by Plasma ion beam and monopolar radiofrequency treatment. Surgical incision is also an option for severe cases. II van box type Treatment: Plasma and other ion beam to repair the epidermis. For deeper or larger acne scars, fat filler can be used to restore the plumpness and luster of the skin, and of course, surgical incision can be chosen for severe cases. Ⅲ Crush type Treatment: Plasma plasma beam, combined with autologous fat filler or surgical incision depending on the severity. IV raised type Treatment: Fractional laser + drug closure + Plasma combined treatment or surgical incision combined with post-operative electronic ray irradiation. Many people do not have a single type of acne scar, but often combine two or more types, so the treatment plan is not absolute, and the specific one can be determined only after seeing the doctor. We hope that through comprehensive treatment, everyone’s acne scars can be effectively improved and return to a charming life.
