Types of Laser Hair Removal

types-of-laser-hair-removal

Laser hair removal is essentially a method wherein hair follicles are destroyed using laser beams or laser heat[1]. The laser beams produce an intense heat that not only damages the hair follicle that it is directed at, but also has the ability to prevent the growth of hair follicles henceforth, although permanent removal is not guaranteed by this method as of now[2].

Laser hair removal is offered by most dermatologists and medical spas, and is even being offered by salons and hair removal centers in malls. It is important to familiarize yourself with the types of laser hair removal and what exact procedure is suitable for you and your skin type in order to achieve the best results possible and avoid any skin damage.

The Diode Laser

The diode laser is one of the earliest types of lasers that was approved by the United States Food and Drug Administration (FDA)[3] and has since proven to be the most effective and widely recommended type of laser removal method[4].  The diode laser has a wavelength of 800-810 nm, and a pulse width of 5-30. It is highly recommended for white or fair skin, however it may also be effective in removing hair in light to dark brown skin[5].

The Alexandrite Laser

The alexandrite laser has a 755nm wavelength and is used for very white skin and is compatible for the removal of hair in large areas of the skin because of its ability to penetrate the skin deeply[6].

The Ruby Laser

The ruby laser is the first laser removal system that was made available commercially. The lasers emitted by this technology are capable of being highly absorbed by the melanin of the skin. Its use however is restricted to light skin that has dark hairs and not for medium to dark skin or skin that has light hairs[7].

The ND:YAG Laser

The nd:YAG laser has an intense light beam and is used on dark skin as well as tanned skin. This method has proven to be effective in hair removal although it is not yet known if it can provide permanent hair removal[8].
