Laser epilation technology follows the principle of “thermo-kinetic selectivity”: similar to solar light – which is easier absorbed by dark materials than be light ones – laser light exclusively heats dark pigments – in this case hair roots, which are also known as hair follicles – to more than 65°C. As a consequence, they forfeit their ability of producing new hair. The surrounding area of lighter color is exposed to far less high temperatures and thus not affected.
In the U.S., Photoderm® was the first IPL device (intense pulsed light device) ever deployed for this treatment called “photo epilation” in 1994. Shortly after, it was followed by the first ruby lasers, then – undergoing a rapid development – by alexandrite lasers, diode lasers and long-pulsed NdYag lasers. The IPL devices, initially partly fraught with severe adverse effects, were significantly advanced by deploying improved filters and other technological advancements.
By now, a number of efficient devices for photo epilation are available. Today, the question is not so much if it is alexandrite, diode, NdYag lasers or IPL devices that are “better” but far more for which skin or hair type the individual device is used and how experienced its operator is in its application. (Of course, quality and performance rates of the individual equipment also play a crucial role!).
Currently, our “laser pool” comprises the devices listed below:
Alexandrit laser “Apogee plus”
“Apogee plus” (launched to the market in September 2012) is the latest generation of alexandrite lasers developed by US-based company Cynosure in cooperation with some of the world’s leading laser centers and laser users. The Bodyclinic has been deploying the by now seventh generation of this excellent device since December 2012. With a performance of 20 Joule/cm² at 18mm beam diameter or 30 Joule/cm² at 15 mm beam diameter, respectively, and 2 Hz pulses, it is one of the most powerful and fastest alexandrite lasers in the world. The option to choose among various pulse lengths facilitates highest efficiency at ideal skin protection, as compared to other devices. As a result, undesirable hair is removed safely, quickly and lastingly.
Cutera Xeo platform including:
NdYagLaser “Cool-Glide Excell”: NdYag laser (1064nm) “Cool Glide Excel” was designed by Altus-Medical (today known as CUTERA) to allow for laser epilation and treatments of undesirable surface cutaneous vessels. With its performance of 60 Joule/cm² at 10 mm beam diameter and 2 Hz pulses, it is an extremely fast and efficient NdYag laser. The low absorption level for this light color through pigmented structures leads to the key advantage that this laser is also most suitable for tanned and/or very dark skin types. (A specific application for this laser is for instance chronic facial hair follicle inflammations suffered from by black Africans).
