You can observe it for a while to see if it will fade. If it is on the face, be careful not to use some irritating drugs or cosmetics! If it is pigmentation, it will disappear by itself, if it is spots, it will not fade by itself. I suggest you go to a relatively regular big hospital for treatment, otherwise your face will be ugly! Be careful not to wipe with hormone drugs casually! ! ! There is a plastic surgery hospital near my home, which has a good reputation. You can go and have a look. It's called Fuzhou Beverly Plastic Surgery Hospital.
