By 2008, the number of products on the market that claimed to "brighten" or "illuminate" skin increased by 100percentt, according to Mintel research.
We considered the analysis exploratory and further investigation is warranted to confirm this finding and to illuminate skin carcinogenesis.
Continuous assessment of piloerection was carried out by means of an optical recording device, which captured video data from the unilaterally illuminated skin surface (Benedek et al., 2010).
Using spectrophotometric methodology, pulse oximetry measures oxygen saturation by illuminating the skin and measuring changes in light absorption of oxygenated (oxyhemoglobin) and deoxygenated blood (reduced hemoglobin) using two light wavelengths: 660 nm (red) and 940 nm (infrared) [ 1, 2] (Fig. 1).
The unit is placed in contact with the skin surface, and a high-intensity light emission diode illuminates the skin with wavelengths of 400 1000 nm, spanning the visible spectrum and a small range of the near-infrared spectrum.
"With so many people wearing minimal makeup when it's hot out, this product helps illuminate the skin and helps the foundation you use glide on, so your skin just glows," she says.
Flickering embers illuminate their skin.
The diodes rapidly illuminate the skin at five different wavelengths, or colors, and the light is polarized -- that is, the waves are all oriented in the same direction -- so that it will penetrate the skin.
Walk into a national chain drugstore, feel the fluorescent lights illuminate your skin as they reflect off the tinsel and the cellophane wrapping the bazooka-sized candy canes on the shelves; let the cloying, all-too-familiar melodies of hackneyed Christmas carols flood your eardrums like nostalgic cholesterol, try not to think about death.
