Laser hair removal uses a high energy light source to deliver laser energy to the hair follicle.  Done properly, it selectively damages the hair follicles while not affecting the surrounding skin.

Thanks to advances in technology, laser hair removal can be safely done in all skin types.  Hair must be brown or black to serve as a target for the laser, and at this time blond or red hair does not respond.  Multiple treatments are usually required.  Re-treatments are done when the hair regrows, generally at intervals of 4-8 weeks. 

While generally safe, improper use of laser devices can occasionally result in unwanted side effects.  Laser treatments are best supervised by a board-certified dermatologist and/or someone with expertise and training in laser surgery.
