Good surgical technique and infection prevention can stop surgical scars, but they often form despite the best methods, says plastic surgeon Kelly Gallego. Surgery, silicone dressings, pressure, corticosteroids, radiation, cryosurgery, lasers, vitamin E and other topical treatments can lessen the appearance of scars and prevent recurrence, he said. The choice of treatment depends on the patient and type of scar. "Some patients with hypertrophic or keloid scars may be poor candidates for surgery because the risk of recurrence might be unacceptably high."
