Laser hair removal is a treatment of choice for removing unwanted hair from the body. Hair growth originates in the follicles. The technique uses highly concentrated light (laser) to penetrate the hair follicles and arrest its growth. The intense heat from the laser beam damages the hair follicles, reducing the amount and thickness of hair as well as inhibiting future growth.
Before the procedure, the problem hair is trimmed to a few millimeters above the surface of the skin. You are given special goggles to protect your eyes from the laser beam. The procedure is performed under the effects of a topical anesthetic. A cold gel or a special cooling device attached to the tip of the instrument is used to protect and help the laser light to penetrate into the skin. The instrument is set according to the thickness and density of your hair. Your doctor presses a hand-held laser device onto the region of interest. The duration of treatment depends upon the area.
After completion of the procedure, you are given anti-inflammatory cream or lotion and ice packs or cold-water treatment to ease discomfort. Treatments are continued until the hair stops growing. For best results, you may need four to six sittings. Your next treatment is scheduled after four to six weeks.
As with any procedure, laser hair removal also involves certain risks and complications such as pain, blisters, burns and scarring.
