Light Sheer Duet vs Other Laser Hair Removal Machines

Hair-removal professionals have known for a while that the Light Sheer Duet is currently the state-of-the-art laser for hair removal, but now there’s some serious peer-reviewed research to back it up.

Let’s take a quick look at some of the other laser hair removal machines compared to the Light Sheer Duet:

Ruby Laser

The Ruby Laser was actually the first laser invented for hair removal, but the laser wasn’t terribly efficient at that job when it first came out in the 1960’s.

Over time, the laser was refined and did a better job. It uses a wavelength of 694nm which doesn’t work well with darker skin. There is a longer wait between laser pulses to give clients time to recover from each zap, but the downside of that is the extra time required for treatment.

Alexandrite Laser

The Alexandrite Laser was the first laser to come into mainstream use for hair removal beginning in the 1970’s. It uses a longer wavelength of 755nm, and it’s a very fast laser.

The advantage of a fast laser is fast treatment sessions. The disadvantage is those treatment sessions can be painful, although some lasers have built in cooling devices, and some hair removal practitioners can use cooling lotions that help with the discomfort.

Light Sheer Duet

If we skip to the Light Sheer Duet, this laser has a pulsed diode array and has a light wavelength of around 800nm. This slightly longer wavelength seems to be better at penetrating the hair follicle without damaging the surrounding skin.

The laser also uses a vacuum-assist technology to better target the whole hair follicle, and can cover larger areas faster and with less discomfort than other lasers.

YAG Laser

The YAG laser has a light wavelength of 1064nm—the longest of the four lasers discussed on this page. The YAG has also been around for a long time, since the 1960’s, and because of the long wavelength, this laser has many different applications beyond hair removal, in medicine, cosmetic procedures and the military.

The longer wavelength, however, is also its disadvantage. The YAG’s 1064nm beam is just at the edge of what melanin will absorb, and targeting melanin is the science behind laser hair removal. So, often a cream needs to be applied that will be absorbed by the hair follicles and make the YAG more effective against unwanted hair.

The Light Sheer Duet seems to be better tolerated by clients and have better results than the other choices. The longer wavelength means those with darker skin can also be treated with it, but it’s not so long as to be an issue.
