Introduction
Generally speaking, there is no such thing as a "list of good or bad facial moles." Moles are instead classified as either benign or malignant. Common types of facial moles include pigmented nevi, nevus anemicus, Ota nevi, sebaceous nevi, and blue nevi. These can be improved through treatments such as liquid nitrogen cryotherapy, fractional laser therapy, and skin grafting. The specific outcomes vary from person to person.
