Moles generally do not affect health, but only affect facial beauty. But if it grows in a place where it is easy to rub, it is easy to change. The methods of removing moles are: surgical removal, laser removal, freezing removal, drug removal and so on. At present, except for the larger and deeper moles that need surgical resection, the general moles can be treated by laser. Laser nevus removal is the most scientific and best method to remove nevus at present. It uses the huge energy of laser to act on the pigment tissue in an instant, so that the pigment is crushed, decomposed and swallowed by macrophages and excreted with lymphatic circulation, thus achieving the purpose of removing pigment. Mole removal is very common in skin hospitals and the cost is not expensive. Generally, it is calculated by a mole, which is tens of dollars, depending on the size, depth and type of mole.
