If you're not happy with shaving, tweezing, or waxing to remove unwanted hair, laser hair removalmay be an option worth considering. Laser hair removal is one of the most commonly done cosmetic procedures in the U.S. It beams highly concentrated light into hair follicles. Pigment in the follicles absorb the light. That destroys the hair. Benefits of Laser Hair Removal Lasers are useful for removing unwanted hair from the face, leg, arm, underarm, bikini line, and other areas.
