Scars are generally referred to as keloid scars, and there is no method for keloid scars to heal themselves, which can be improved by medication, physical therapy and surgery. 1. Medication: Keloid patients can follow the doctor’s instructions to inject glucocorticoid drugs such as triamcinolone acetonide and betamethasone, which can stop the growth of keloid scars. 2. Physical therapy: For patients with small keloids, laser therapy and radiofrequency therapy can be used to rearrange the collagen fibers in the keloid, thus promoting the fading of the lesions, but usually requires multiple treatments. 3. Surgery: If the keloid is large, it is recommended to take surgical treatment, such as skin flap transplantation, keloid excision and suture, etc. After the operation, with local superficial radiotherapy, it can improve the scar. The treatment of keloid is more difficult, usually there is no self-healing method, it is recommended that patients go to the hospital, under the guidance of the doctor standardized treatment.
