The Beauty Brains recently received a promotional unit of the new Silk’n Flash & Go permanent hair remover. For those of you not aware of this device, it is one of several products that uses FDA-approved Intense Pulsed Light technology to reduce hair growth at its source. Since it takes several weeks to see how effective it is, today I’ll talk about the device itself and next time I’ll blog about how well it works.
How does IPL hair removal work?
Intense Pulsed Light (IPL) uses a Xenon lamp to produce to strong flash of light of a particular wavelength. (IPL is NOT a laser. Lasers produce a single wavelength of light, IPL produces a broader spectrum.) This wavelength is chosen because it is easily absorbed by melanin, the natural pigment that gives your hair and skin their color. Melanin particles are concentrated near the root of hair. When the device flashes, the light is absorbed by the melanin which heats up and destroys the nearby cells in the hair root. Over time the bulb is destroyed to such an extent that it will not grow hair at all, or at least grow much less hair. This process, which has the cool name “photoepilation” is not technically a hair removal method, rather it is a hair reduction method.
This technology is used in similar devices such as the Remington, the Lumi, and the Viss. The No No device uses a different technology which generates a thermal pulse to destroy hair.
Are there any side effects?
Some users have reported a rubber band like snapping sensation in their Silk N review. I’ll be sure to address the sensations during use after I’ve had a chance to try it out. One known concern is that you should not use this device if you have dark skin or even a dark suntan. That’s because the “extra” melanin can cause the absorption of light closer to the surface of the skin and presumably cause a burn. Also, there is some concern that the destructive thermal energy may damage cells other than those responsible for hair growth. While the FDA has approved this device as safe for use there is at least one paper in the literature that raises the question of neighboring cell death. (See references.)
How well does it work?
I’ll be back in a few weeks with the results of my testing (even though my assessment will be based on just anecdotal data.)
