After mole spotting, patients can apply topical ointment to promote wound healing, commonly used are recombinant human epidermal growth factor gel and recombinant bovine basic fibroblast growth factor gel, which can be applied topically on the wound surface to promote wound healing in clinical. Patients should also pay attention to the protection of the wound. Some patients accidentally rub off the scab or get wet after mole spotting, which is likely to induce local infection, and once skin infection is induced, topical repair creams are useless. Once the infection is triggered, topical restorative creams will not help. After the infection is triggered, regular anti-infection treatment should be applied, otherwise the patient is likely to have obvious scar tissue or obvious hyperpigmentation at the mole site.
