Epilation by laser was performed experimentally for about 20 years before it became commercially available in the mid 1990s. Intense Pulsed Light (IPL) epilators, though technically not a laser, use xenon flash lamps that emit full spectrum light. Laser and light-based methods, sometimes called phototricholysis or photoepilation, are now most commonly referred to collectively as "laser hair removal". One of the first published articles describing laser hair removal was authored by the group at Massachusetts General Hospital in 1998.

The efficacy of laser hair removal is now generally accepted in the dermatology community, and laser hair removal is widely practiced. Many reviews of laser hair removal methods, safety, and efficacy have been published in the dermatology

Laser hair removal is a medical procedure that uses laser light — an intense, pulsating beam of light — to remove unwanted hair. Laser hair removal works by passing a light beam through the skin. The laser targets dark pigment, called melanin, in hair. When the light beam hits the hair follicle (where hair growth originates), the intense heat destroys the hair follicle instantly.

Laser hair removal is used for people who want to remove unwanted body hair. Common treatment locations include legs, armpits, upper lip, chin and bikini line. However, it is possible to treat unwanted hair in almost any area of the body.

Although laser hair removal doesn't guarantee permanent hair removal, it does extend the hair-free period, which can vary from several months to many years. With multiple treatments, long-term hair removal is possible.

Hair color and skin type are the key factors that influence the success of laser hair removal. It's most successful on people with dark hair (brown or black) and light skin. However, it can also be used safely on people with darker skin types. Laser hair removal does not work for white, blonde, light brown or light red hair.

To reduce your risks, choose a qualified, trained doctor who is board certified in dermatology or a similar specialty. Your doctor should meet with you before the procedure and determine your treatment plan. If a physician's assistant or licensed nurse performs the procedure, your doctor should supervise and be available on-site during the treatments. Do not go to a spa, salon or clinic that allows nonmedical personnel to perform the procedure.
