You can go to the hospital for face-to-face consultation or go to the pharmacy to buy drugs such as skin care, scar and hirudoid to prevent scar hyperplasia after burns and cuts. However, these are more effective when you are just injured. Your situation is probably useless. But talk is better than nothing. Buying a tube may dilute it a little.
The most effective thing is to do a laser beauty project (please go to the plastic surgery department of a public 3A hospital to see a doctor).
