When there are many moles on the face, the first thing to do is to check whether they are deteriorating, especially for moles that have suddenly increased or grown recently, or even broken or oozing, or moles with uneven pigmentation on the surface. It can be clarified by skin CT or dermoscopy, and preferably by skin histopathological examination. In terms of treatment, laser treatment, iontophoresis or cryotherapy can be applied. The best treatment option is surgical excision because it can be deeply cut or expanded to remove the abnormal nevus without causing residue. During the treatment period, alcohol and spicy food should be avoided, and fusidic acid ointment should be applied daily after the treatment to prevent infection.
