Medication: If the scar is early, you can use topical medication to get rid of the scar, such as cumulonimbus cream ointment, etc. But if the scar has been formed for a long time, you can use glucocorticoid drugs to close the treatment. But if the scar formation time has been relatively long, you can use glucocorticoid drugs for closed treatment, such as tretinoin acetate cream, etc., so that the local fibroblast function is inhibited, prompting scar atrophy. 2. Laser treatment: laser is mainly the use of specific wavelengths of light selective action on the local skin, penetrate the surface layer of the skin, into the dermis, destruction of scar tissue, and at the same time to stimulate the regeneration of collagen fibers, so as to improve the scars. 3. Surgery: If the scar has been formed for a long time and affects the function of the body, surgery can be considered to remove it. Such as keloidectomy after the reduction of tension fine suture, skin grinding, keloid release local reshaping surgery, keloidectomy free skin grafting, and so on.
