Laser is useful for removing unwanted hair from the face, leg, arm, underarm, bikini line, and other areas.

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.

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' 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.
