Get the Facts About Common Cosmetic Procedures: Laser Hair Removal

What is it? A noninvasive technique that uses a low-energy laser beam to disrupt the hair follicle growing cycle.

Why might I get it done? To remove unwanted hair on your face or body.

Who is it appropriate for? Best for people with light skin and dark hair, although some lasers work on darker skin, and certain medications can be applied to lighter hair to improve follicle destruction. You should also have the patience and financial means to undergo the several sessions required, along with occasional maintenance treatments.

How is it done? You wear goggles to protect your eyes from the damaging laser rays. The laser is applied directly to your skin and the intense heat follows the pigment of the hair down to the follicle and destroys it. You don't feel the heat on your skin, however. Depending on the area to be treated, it may take a few minutes (upper lip, eyebrows) or a couple of hours (legs, back).

What is the pain factor? Pain varies depending on the area, ranging from slight stinging to feeling like a rubber band snapping against your skin. However, an anesthetic cream can be applied to the area. Just make sure your doctor uses the lowest amount possible of numbing cream because the FDA has received reports of serious and life-threatening side effects after using large amounts of topical anesthetic during laser hair removal.

What are the expected results? Permanent reduction in hair; the FDA does not allow manufacturers to claim permanent hair removal.
