Laser hair removal is a medical procedure that uses a concentrated beam of light (laser) to remove unwanted hair.
Just before the procedure, your hair that will be undergoing treatment will be trimmed to a few millimeters above the skin surface.
Usually topical numbing medicine is applied 20- 30 minutes before the laser procedure, to help with the sting of the laser pulses. The laser equipment will be adjusted according to the color, thickness, and location of your hair being treated as well as your skin color.
During laser hair removal, a laser emits a light that is absorbed by the pigment (melanin) in the hair. The light energy is converted to heat, which damages the tube-shaped sacs within the skin (hair follicles) that produce hairs. This damage inhibits or delays future hair growth.
Although laser hair removal effectively delays hair growth for long periods, it usually doesn’t result in permanent hair removal. Multiple laser hair removal treatments are needed for initial hair removal, and maintenance treatments might be needed as well. Laser hair removal is most effective for people who have light skin and dark hair.
