How does the Altus CoolGlide Xeo differ from older laser systems?
Other laser and intense pulsed light systems include: Intense pulsed light – these systems are flash lamps producing a spectrum of light energy rather than laser light. Intense pulsed light systems tend to stun rather than kill hair follicles, so that there is often an unacceptable amount of hair regrowth, even after many “intense pulsed light” treatments. First generation Ruby 694 nanometer (Epilaser, Epitouch, Chromos) Second generation Alexandrite 755 nanometer (Epitouch ALEX, Photogenica LIPR, GentleLASE) Third generation Diode 800-810 nanometer (LightSheer, Apex) These relatively short wavelength lasers can produce good results in some circumstances, but because they produce light which has a shorter wavelength, their laser energy both scatters more in the skin, and is mostly absorbed in the top few millimeters of the skin, above many of the hair roots. This means that sometimes not enough energy reaches the hair roots, where it is needed. These short wavelength, lower power syste
