Okay, I'll answer that. After consulting two companies, it turned out that Chen Qinggui made it in Huadu and took three. One of them was not cleaned and left a mark. I went to get it again some time ago, because they promised not to clean it, so I can't tell what color it is. If my skin is white, I won't know, but I want to tell you that there is a light mark. If your skin has no acne, acne and blackheads, it is not recommended to take it, at least I don't. I heard that there will still be some marks after operation, but it's not very nice. If your skin is flawless, the marks may be more obvious. I suggest you consider it carefully.
