I think it's better to go to the hospital. Hospitals are absolutely guaranteed. Do you have enough money? If yes, go to the First Affiliated Hospital of Sun Yat-sen University. Even if there are scars, that hospital can handle them. Laser. Absolutely safe and painless. And the chances of longer are not great. Don't go to the beauty salon without authority. It doesn't help much to use pea medicine. The most important thing is not to eat too much greasy food. There is no cake.
