The management of small wounds that scab over and leave scars includes topical medication, physical therapy, and surgery. Scars, also known as keloid scars, are the product of the healing process of human trauma or inflammation. 1. Topical medication: Silicone gel can be used to prevent scar formation in the early stage of wound healing, and if a scar has formed, local injection of glucocorticosteroids, such as betamethasone, can be used to promote scar recession. 2. Physical therapy: Fractional laser and radiofrequency therapy can be used to promote the rearrangement of collagen fibers in the scar tissue to promote scar receding. 3. Surgery: For localized hyperplastic scars or keloid scars, surgical excision and postoperative combination of local superficial radiation therapy can be used to remove the keloid scars. It is recommended that patients according to their own situation, if necessary, to the regular hospital dermatology consultation, follow the doctor’s instructions to choose the appropriate treatment, medication, strictly comply with the doctor’s instructions to use drugs, not blindly self-medication.
