How the sun sees you

Bert and I talked about how skin is transparent in varying degrees to light of different wavelength, and he found this video, showing latent stuff like freckles showing up on an ultraviolet camera.

I'm not surprised. Many people find freckles icky, on others or on themselves. (I find many freckled girls beautiful.)
... and to then seem them *hiding* just under the skin like that... Ooooh.

This is also a subliminal sunscreen ad, isn't it?

Sunscreen isn't that healthy either. Rather use an umbrella, like Asian ladies, unless one has really dark skin. :)

Would an umbrella not work with dark skin??

I don't know about sunscreen, but an umbrella is not so practical if you need to use both hands, as in sports or swimming.

Very true; they say that sunscreen is causing Vitamin D deficiency, for one, which is a HUGE problem...in North America, anyway...and the studies, basically, say that most everyone above the 35th parallel is Vitamin D deficient...

Yes...reading a fascinating book on skin pigment and natural sunscreening thereof... :-D

If you are dark-complected, you have natural "built-in" sunscreen in your skin pigment... :-D

The other fascinating/interesting thing, re: the various UV rays is that there are far more "good" rays than harmful rays reaching Earth; also discussed in [fascinating] above-mentioned book...
