It’s interesting to see the evolution of the in-home laser market. For those with large treatment areas, not near a laser center, or feel timid about strangers working on them, the in-home laser is an ideal solution.
Having seen the success of laser first hand, with over 20 sessions for various areas, I can say high-fluence diode lasers do work for permanent hair reduction. However it seems most laser in-home systems are far too underpowered for permanent reduction (Rio, Epila, Viatek, etc), and resemble laser pointers in a fancy case.
The Silk’n is a lightbulb (IPL), not a laser. It’s designed for feminine hairs, likely because it’s limited to 5 J/cm2 on a 6 cm2 spot size. This doesn’t approach high-fluence laser solutions.
In my treatments I used a Coherent Light Sheer XC and required between 28 and 38 J/cm2 on a 12 cm2 spot size, over the course of 8 treatments for full arms.
The Tria (by SpectraGenics) sounds a little more promising, as it’s a diode laser that can reach 24 J/cm2. However with only a 1 cm spot size, and battery-only operation, how long would it take to do a large area?
The P&G/Palomar unit, another true diode laser, has been in development for 5 years and has had OTC FDA clearance since 2006 (the first one given). They recently finalized their licensing agreement, but has anyone heard any technical details or a launch date? If it’s OTC, it may be even less powerful than the Tria, but it would be the first widely available product that I know of.
