First of all, skin grafting can remove scars on hands and cover them with skin from other parts of the body. Plastic surgery hospitals can do it now, and the effect is good. The cost is high, and you can't do it without some money.

The second is to ruin the scar by profiteering. For example, use a blade to cut off the smoke scar, so that the growing skin is new skin. The color of the grown skin is dark, and it will become normal after a few years, but the good skin has color difference. You have to go to the hospital to do this, but there is no skin grafting step. If you do it yourself, it is easy to be infected. Do it yourself is not recommended.

Third, it is said that laser can remove scars, but I heard that it has never been seen before.

You must accept your mistakes. Nowadays, young people burn fireworks, tattoos and tattoos impulsively to show their courage and loyalty, which leads to various restrictions and blows when entering the society. Just remember that Bai Yushi is perfect.
