Scar marks generally refer to keloid scars, which are the end result of human trauma repair and can be eliminated by medication, physical therapy and surgery. 1. Medication: For patients with scarred skin, silicone gel can be used externally as prescribed by the doctor, which can soften and thin the scar. 2. Physical therapy: Commonly used is laser, using pulsed dye laser to close the abnormally constructed capillaries, stopping the growth of keloid scar, improving the red appearance of the scar, thus making the scar become less obvious. 3. Surgical treatment: for some smooth and soft surface scar, skin abrasion can be used to restore the skin to a better color. For larger hyperplastic scars, keloidectomy and free skin grafting can be used, together with local radiotherapy or photodynamic therapy, to repair scar wounds and improve aesthetics. There are many ways to remove keloid scars, and localized closed treatment is also available. It is recommended that the patient can go to the hospital to consult the physician, to take the appropriate method to remove the scar.
