Moles on the face generally refer to nevi, which can be categorized into intradermal nevus, junctional nevus and composite nevus according to the location of the nevus cells in the skin. Usually, they do not require any special treatment, but if they affect the aesthetics of the face, they can be improved by physical therapy or surgical treatment. Intradermal nevus is located under the epidermis and in the superficial layer of the dermis, junctional nevus is located at the epidermis-dermis junction, and compound nevus is located in the epidermis and dermis. Generally speaking, nevi do not need special treatment, but if they are aesthetically disturbing, they can be removed by laser, electrocautery and surgery. In addition, if the local nevus has irregular shape, unclear boundary, uneven distribution of pigment and symptoms such as ulceration and itching, it should be alerted to the possibility of malignant transformation, and it is recommended that patients go to regular hospitals as soon as possible for early excision and histopathological examination.
