Is the scar too long? As long as the self-repair period is more than 3 months, you can go to a regular plastic surgery hospital for scar repair. At present, the most advanced laser instrument can safely remove scars, and the red one will be relatively difficult to remove, because the sensitivity of red to light is relatively weak, and it can still be removed after several times. The key is to choose a regular professional hospital for treatment, Hua Fu. You can think about it. I have friends who have done it there, and the effect is really good, which matches the surrounding skin.
