The process takes from several minutes to several hours, depending on the area of the body involved. Laser hair removal uses a low-energy laser. The laser energy passes through the patient's skin, being absorbed by the pigment in the hair follicle. A percentage of the follicles are instantaneously and permanently disabled with each treatment. In most cases, no anesthesia is necessary.
