An Nd:YAG laser is safe for laser hair removal in dark, even black skin. The risk of laser hair removal in dark skin is typically damage to the epidermis, or the uppermost layer of the skin. The reason is that dark skin absorbs the laser more than light skin and can act as a target for the laser. The Nd:YAG has a wavelength that is longer than other lasers used for laser hair removal. For this reason, it can penetrate deeper into the skin, bypassing any damage that may occur at the skin's surface.
It is still necessary to use lower settings in darker than lighter skin and the area that is lasered should be sufficiently cooled with ice pack, laser tip, etc to protect the uppermost layer (epidermis). A test spot in an inconspicuous area is strongly advised prior to undergoing laser treatment of any kind, especially in dark skin. please make sure to go to a dermatologist or plastic surgeon to ensure both safe and effective treatment.
