If you are a light skin type (Caucasian), either of these lasers are appropriate for you. The GentleLase is an Alexandrite laser and the Lightsheer is a Diode laser. Although they are slightly different types of light (755nm for Alex and 810 for Diode) they are both very effective for light... more
LightSheer vs. GentleLASE - what's the difference?
Lightsheer and GentleLASE are two brand names of laser hair removal treatments - I get that. What I don't get is the difference between two. How do I know which one is better?

A: Lightsheer v GentleLase
These are laser brand names. Each of these lasers represents a completely different laser subtype. The Lightsheer is a diode laser and the GentleLASE is an alexandrite laser. I have used these extensively and these two lasers function at very different wavelengths. Therefore one of these lasers will penetrate... more

Gentlelase Laser, manufactured by Candela, is a laser type known as an "alexandrite" laser. Alexandrite is rock mineral gemstone. Synthetic alexandrite is used as the active laser medium for alexandrite type lasers. The LightSheer laser is manufactured by Lumenis and is a laser type known as a "diode" laser. Diodes are semi-conductors, through which an electrical current is passed to stimulate laser energy. Alexandrite lasers are in the 755 nm range of light, while diode lasers are in the 800 nanometer range. As such, the LightSheer diode laser is slightly longer wavelength of light. In my opinion, both lasers are highly effective. I've seen similar laser hair removal outcomes with both lasers. In terms of how the laser feels on the skin in terms of sensation, I also rate them similar. These lasers are ideal for lighter colored skin. However, I find the LightSheer laser provides me with more treatment options for darker-skinned patients or even my tanned-skin clients. By adjusting fluence and pulsewidth settings, I can accomodate, with greater confidence, a wider range of skin types.
