Scar can't be completely removed as long as it remains, but it can be made inconspicuous through treatment. The stable period of scar is 3-6 months, during which scar paste or scar cream can be used for treatment. The treatment methods that can be adopted after the stable period are: surgery, which is suitable for large scars. Different schemes vary according to the specific shape of scars, such as staged resection, catgut embedding dilator and skin grafting. Injection, suitable for people with scar constitution. Microcrystalline grinding is suitable for some superficial scars. It depends on your situation. I suggest you go to a regular hospital to see an expert and make a plan that suits you.
