If you're not happy with shaving, tweezing, or waxing to remove unwanted hair, laser hair removal may be an option worth considering. It beams highly concentrated light into hair follicles. Pigment in the follicles absorb the light. That destroys the hair. Lasers are useful for removing unwanted hair from the face, leg, arm, underarm, bikini line, and other areas.
Benefits of laser hair removal include:
Precision. Lasers can selectively target dark, coarse hairs while leaving the surrounding skin undamaged
Speed. 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 ev ery 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.
Predictability. Most patients have permanent hair loss after an average of three to seven sessions.
How to Prepare for Laser Hair Removal - If you are planning on undergoing laser hair removal, you should limit plucking, waxing, and electrolysis for six weeks before treatment. That's because the laser targets the hairs' roots, which are temporarily removed by waxing or plucking.
You should also avoid sun exposure for six weeks before and after treatment. Sun exposure makes laser hair removal less effective and makes complications after treatment more likely.
Recovery - For a day or two afterward, the treated area of your skin will look and feel like it's sunburned. Cool compresses and moisturizers may help. If your face was treated, you can wear makeup the next day unless your skin is blistering.
Over the next month, your treated hair will fall out. Wear sunscreen for the following month to help prevent temporary changes in the color of the treated skin.
Blisters are rare but are more likely in people with darker complexions. Other potential side effects are swelling, redness, and scarring. Permanent scarring or changes in skin color are rare.
