It may depend on the skin quality, just like someone who has acne and left a pit can't see anything. If it's not scar skin, then there's no problem. Plastic surgery department in a big hospital or go to a professional beauty salon. I think it is guaranteed there, hehe.

Ps: It's only a matter of time before it grows back after burning. Some people around me surfaced again in 2~ 10.

Personal advice is painful if it doesn't affect the appearance very much. . .
