Keloid scars are generally ineffective with topical medications, and need to be improved through local closure, fractional laser, and surgical treatment. 1. Local closure: Glucocorticoid drugs have strong anti-inflammatory effect, local closure can inhibit the growth of scars, reduce the thickness of scars, and make scars degenerate. 2. Fractional laser: The heat energy generated by laser treatment can cause thermal damage to the scars and promote the rearrangement of collagen and elastic fibers in the dermis layer, so as to achieve the purpose of removing the scars and fading the scars. 3. Surgery: For the scar that is not well treated by local closed treatment and laser treatment, surgery can be chosen to remove the scar, which should be combined with local superficial radiotherapy to prevent the keloid from forming again. Due to the different physique of individuals, the treatment will also have certain changes, the specific situation needs to be analyzed by the doctor in conjunction with the actual situation.
