do people really fall for this nonsene???
if you look at the science behind this then it's flawed - big time.
the scanner works - no doubt about that - but all it does is tell you what the concentration of your skin carotenoids are. carotenoids (beta-carotene and lycopene mainly) are only part of the antioxidant equation and to do any good - IF they do any good and the jury is very much out on that - they need to be intracellular or in the bloodstream, not the skin. they may help prevent some skin damage in the skin but they are not going to help elsewhere.
and at the end of the day, the company promoting this scanner only wants to sell you supplements so that your skin levels are fine. and in 1997 the parent company, Nu-skin, were fined by the FTC in the US for misleading claims on supplements they sold.
it's complete and utter pseudo-scientific bollocks - don't waste your money
