A nevus, also called a nevus nigricans. It is produced by a group of benign melanocytes that accumulate at the junction of the epidermis and dermis. The melanocytes may be distributed in the lower reticular dermis, between bundles of connective tissue, around other appendages of the skin such as sweat glands, hair follicles, blood vessels, nerves, etc., and occasionally extend into the subcutaneous fat. It may appear flat, raised, warty, granular, or other shapes, and may be brown, black, or blue in color. There are two types of nevi: congenital and acquired. Most congenital nevi are present at birth or during the neonatal period, while acquired nevi may grow newly after six months of age and into old age. Acquired moles are usually 0.1 to 0.6 cm in size, and can be divided into three types: joint moles (moles with cells confined to the junction of epidermis and dermis, which are intra-epidermal moles), compound moles (moles with cells not only in the epidermis but also downward into the dermis), and intra-dermal moles (moles with cells completely in the dermis). Although they are diagnosed as benign and harmless to the body, they do affect the overall beauty of the face. Many parents worry that moles will affect the appearance of their babies, and some young people who love beauty are trying to remove their moles by all means. So how to remove this annoying mole? Many places will tell patients to use laser to remove moles, but they don’t know that there are many kinds of moles and many kinds of laser wavelengths, and many doctors, even those who are not qualified to practice medicine, don’t know how to use laser to remove moles correctly. In practice, laser mole removal often cannot be removed at one time and requires a recovery period of 2-3 months before the next treatment, so many patients cannot adhere to the time and course of treatment. Some patients also have skin infection and other symptoms after receiving laser treatment, leaving unsightly scars, and the moles are not removed, but add new troubles.
