Laser hair removal is a medical procedure that uses laser light Рan intense, pulsating beam of light Рto 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. All of this happens during each session of treatments. The number of treatments done determines the total laser hair removal cost.  Laser hair removal was discovered by accident in 1992 when a laser physicist zapped himself on the arm and then noticed that the hair on his arm was gone. In 1995, the first use of laser for hair removal was approved by the FDA. The treatment was not actually permanent, as the claims said. The technology and results have improved greatly since these beginnings.

Laser light passes harmlessly through the skin. In the case of hair removal, heat energy from the laser destroys the hair bulb by the process of photothermolysis. The skin is quickly cooled through the application of a cryogen spray, circulating cool water, or a gel.

First generation lasers used a solid beam of light. Pulsed light is different from a laser. While it is still energy, and measures similar to a laser, pulsed light (or photo light) produces a quick “flash” of light (similar to a camera flash). Pulsed lasers emit bursts of energy at intervals of a thousandth to almost a billionth of a second. These short, powerful pulses shatter their target without allowing heat to build up and burn the surrounding skin.

The flash destroys the vein or hair bulb. Improved since its first introduction in the United States, it is widely used in the medical arena or in medical spas. While there is always a risk of scarring with any laser procedure, this newer laser technology greatly reduces the risk of scarring, which in most cases is less than 1%.

There are many claims that laser hair removal is permanent. In the case of lasers, permanent hair reduction is defined as semi-permanent. The laser hair removal device will permanently reduce the number of body hairs, however, it will not result in the permanent removal of all hair. As a result, most clients will go through a series of treatments to achieve full, permanent removal of all hair in the desired area.
