Laser hair removal is one of the most common cosmetic procedures in the U.S. It beams highly concentrated light into hair follicles. Pigment in the follicles absorbs light which destroys the hair. If you’re not happy with shaving, tweezing, or waxing to remove unwanted hair, laser hair removal may be an option worth considering. Lasers are useful for removing unwanted hair from the face, legs, arms, underarms, 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 eliminate multiple 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.
Predictability: Most patients have permanent hair loss after an average of three to seven sessions.
How to Prepare for Laser Hair Removal
Laser hair removal is more than just ”zapping” unwanted hair. It is a medical procedure that requires training to perform and carries potential risks. Before getting laser hair removal, you should thoroughly check the credentials of the doctor or technician performing the procedure. 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’ shafts-root complex and the shafts 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.
What to Expect During Laser Hair Removal
Just before the procedure, the selected removal area will be trimmed to a few millimeters above the skin surface. The laser equipment will be adjusted according to the color, thickness, and location of the hair being treated as well as your skin color.
