Types of Lasers and Light Sources Are Used for Hair Removal
There are a few different laser and laser-like devices currently used for hair removal. These are:
Alexandrite which is the long-pulse alexandrite laser and achieves deep penetration into the dermis where the hair follicles are located. The heat build-up in the hair shafts disables those follicles in the active growth phase.
Diode laser which is a very efficient device that contains small diodes or semiconductors that are arranged together to produce light. The diode laser has a longer wavelength than other lasers used for hair removal, which may improve treatment results on darker skin types.
Light-Based Sources which is an intense pulsed light devices operate on similar principles to lasers. Using the photoepilation process, the device offers a broad spectrum of light to treat a variety of hair and skin colors as well as hair depths.
Q-Switched Nd and this laser delivers two different wave lengths of light. One is an invisible infrared light used for deeper penetration. This wavelength is used to reach deeper hair follicles. The other wavelength, a green light, is used for treating hair follicles closer to the surface. In both cases, the Q-switching device emits rapid bursts of laser light to the treatment site.
Finally, Ruby which is the red-colored beam seeks out the target melanin inside the hair shafts
