Nonsense, this patient is obviously scarred, and whatever knife you use, the laser can only grow bigger and bigger. You can choose intradermal injection of glucocorticoid to soften and break the thin papules, but the final effect is probably the best, that is, it can be flush with the surrounding skin, but the color is still different. If you choose surgery or laser, you must use shallow X-ray radiotherapy after surgery or laser to prevent scar tissue growth, but it depends on whether there is a dermatological hospital in this area near you.
