Scar is a stubborn disease that is difficult to cure. At present, there are many methods to treat this disease at home and abroad, such as laser, freezing, surgical excision (skin grafting), radiotherapy or local hormone blocking, but not everyone can achieve good results, so it is best to consider going to a regular hospital for examination before deciding how to treat it. Surgery can't completely solve the problem of scar. Scars will also form after the operation, just replace the obvious scars or big scars with smaller ones.
