If you're not happy with shaving, tweezing, or waxing to remove unwanted hair, laser removal is a good treatment option for you. Lasers can be used to remove unwanted hair from the face, leg, arm, underarm, bikini line, and other areas. Lasers selectively target dark, coarse hairs while leaving the surrounding skin undamaged. Each pulse of the laser takes a fraction of a second and can treat many hairs at the same time. The laser can treat an area approximately the size of a quarter every second. Small areas such as the upper lip can be treated in less than a minute, and large areas, such as the back or legs, may take up to an hour.
