How the Sun Sees You



Thomas Leveritt showed people what they looked like on video shot in ultraviolet (UV) light. You can see the changes your skin goes through by contrasting young children with adults. But UV light does not see through sunscreen, which is sunscreen’s entire purpose. In UV light, it looks black! But you can see how it protects your skin from the damaging sun’s rays.

I commented on this in another place, but if my experience can convince just one young person not to follow in my footsteps, it bears repeating. I loved the sun, and loved having brown skin. I didn't use sunscreen, because I wanted to get as dark as possible. Now I have to wear long-sleeved shirts all the time because my skin is so damaged. Just a bump can cut the skin, which then often gets infected. I have so many scars you wouldn't believe it. USE SUNSCREEN, PLEASE!
