I came across this video last month by Thomas Leveritt wherein he asked random people to pose in front of an ultraviolet camera. The video shows how ultraviolet radiation from the sun affects our skin over time. We are born with spotless skin but as we age we slowly develop invisible freckles that is only visible to this type of camera. And that by using sunscreen we are preventing these invisible freckles from appearing. It is a good reminder that we should use sunscreen daily even with minimal exposure to the sun.
