We expose our skin to the sun every day whether it's the hottest point of summer or the dead of winter. And while there's nothing better than feeling the sun on your face, if you're not protecting your skin the UV rays are wreaking some serious havoc. You might not see it now, but if you looked under ultraviolet light, it's staggering.

The video below shows people what their skin really looks like underneath -- in ultraviolet light -- and we don't think anyone was expecting what they saw! You have to see it, and then seriously... put on your sunscreen.
