Hyperpigmentation after laser mole spotting may be caused by improper operation and postoperative care. Generally speaking, there will be no hyperpigmentation after laser mole spotting under regular operation, or there will be temporary hyperpigmentation which will subside in a short period of time. However, if the operation is not standardized and strict attention is not paid to disinfection and aseptic operation when spotting moles, there is a possibility of hyperpigmentation; in addition to this, improper care in some aspects after the operation may also lead to the occurrence of hyperpigmentation. 1. Infection: If you don’t pay attention to the scientific care of the treatment area after the operation and cause local infection, the infection will increase the damage to the local tissues, and there is a possibility of hyperpigmentation after the wound is healed. 2. Diet: consuming some stimulating food, not avoiding tobacco and alcohol after surgery will stimulate local capillary expansion, which may increase the probability of hyperpigmentation. 3. Sun protection: just after the treatment of the skin stratum corneum is thin, the skin barrier has not been fully restored. If you don’t pay attention to the ultraviolet shield after the operation, it is very likely to lead to hyperpigmentation. If pigmentation occurs in laser mole spotting, it is recommended to go to the hospital and follow the doctor’s instructions to standardize the treatment.
