Laser hair removal for dark spots is generally safe and well-tolerated by those who use it. The surgery does not appear to be related to any long-term health hazards. Some people, however, may encounter minimal adverse effects as a result of laser hair removal. Before having the procedure done on a wider region of skin, people should ask their dermatologist to evaluate how a small patch of skin reacts to it. People who want to have laser hair removal should always go to a licensed professional.
