You said that the main reason was the scar on the burned face, so it's hard to say whether it can be repaired now. The main thing is that you haven't provided pictures for observation. In addition, the scar tissue itself is very special, and once it is formed, it is difficult to eliminate it. If conditions permit, you can also consider going to the burn department or plastic surgery department of a large hospital at a higher level. After seeing a doctor, explain your purpose first, then look at the actual situation of your face, and then see if you can repair it again according to the results of observation and inspection.
