Treatment for scar on face
From your photo, the scar on your face appears slightly wide and perhaps a bit depressed. It is difficult to know if that is really the case without examining you. If it is wide and depressed, I would say the best option would be to have a scar revision, where the scar would be removed and ideally replaced with a scar that is more narrow and flat. A narrow and flat scar would be less noticeable than your current scar.
