Well, it's not exactly cheap, but we'll get to that in a minute. The
Exideal is a notebook-sized vertical display of light-emitting diodes
(LEDs) intended as a kind of electronic beauty aid. The idea is you sit
in front of the thing and let the flickering LEDs bathe your face in
light, to “permeate the vitamins and collagen in your skin and make you
beautiful from the inside." The Exideal features 280 multicolored LEDs
that light up in various modes, patterns and intensities. Check out the
deeply weird demo video for a case-in-point on Japanese surrealism.
Of course, all the Exideal is likely to permeate is your wallet.
There's no evidence -- or even a decent reason to think -- that bathing
your skin in LED emanations will have any beneficial effect. Then
again, I suppose if evidence and reason were filtering criteria in the
beauty industry, half the store shelves would be empty.
Your skin does need a certain amount of light, though. Well, not so
much an amount as a type of light. Specifically, ultraviolet B
radiation, which triggers production of Vitamin D in the body, critical
for maintaining organ systems. The usual exposure to sunlight does the
trick -- UVB ultraviolet light at wavelengths between 270–290 nm, if
you want to get technical. Commercial LEDs don't go that far down the
electromagnetic spectrum.
There's a whole 'nother conversation here about epileptic seizures, but
I sense it's time to move on. The Exideal system retails for 100,000
yen, or around $900.
