Hair Removal Lasers

The objective of hair removal lasers is the same regardless of the laser equipment used - permanent hair removal.  Other permanent hair removal options are somewhat antiquated when compared to the latest laser technology.  There are several hair removal lasers and laser-like devices used at clinics for the laser procedure. Some of the more common devices are detailed below:

Alexandrite
This long-pulse alexandrite laser can get deep penetration into the skin down to where the hair follicles are located. The Alexandrite equipment produces heat build-up in the hair shafts and the result is disabled hair follicles during the active growth phase.

Diode
The diode laser hair removal device is very efficient and contains small diodes or semiconductors that are combined to produce light. The diode laser possesses a longer wavelength than other hair removal lasers.  This characteristic may improve treatment results on those patients with darker skin types.

Light based sources
Though not classified as laser, intense pulsed light devices operate on similar principles to lasers. In the use of the photoepilation process, the device offers a broad spectrum of light that treats a number of skin and hair colors, as well as, hair depths. 

Q-Switched Nd:YAG
This laser device delivers two different wavelengths of light. The first is an invisible infrared light that facilitates deeper penetration. This wavelength is helpful for reaching deeper hair follicles. The second wavelength, a green light, is generally used for treating hair follicles that are closer to the surface of the skin. In either case, the Q-switching device applies rapid bursts of laser light to site of the treatment.

Ruby
The Ruby type is a light-based source where the red-colored beam targets the melanin inside the hair shafts.

Regardless of which type of hair removal lasers or equipment that your chosen clinic utilizes, almost all laser hair removal equipment has been certified by the FDA as being safe for hair removal.  If you have any doubts after talking to your hair removal specialist, visit the FDA's website for a list of approved hair removal lasers and related equipment.
