In some areas, people call pigmented moles nevi, but they are actually the same thing. It is a benign tumor of melanocytes and the color can be skin color, light brown or even dark brown. The depth in the skin is different, and many pigmented moles cannot be removed by laser. Pigmented moles are generally not recommended to be laser spotted, but it is not absolutely impossible to do so. If you want to do so, you must ask a professional dermatologist to make a clear diagnosis first, and selectively treat them according to the specific rash situation, so that they can be cleared at once as much as possible. The reason why laser is not recommended is that if the diagnosis is not clear and the morphological and pathological basis of the pigmented nevus is not well understood, it will not be removed cleanly if it is shallow and will easily recur, and it will leave pits if it is deep. In addition, what some patients think is a “nevus” is actually a pigmented basal cell carcinoma or melanoma, so indiscriminate laser or “potion” not only affects the diagnosis, but also stimulates the deterioration of the lesion. It is not related to the distance from the eyes and does not affect the nerves.
