sunscreen

In 2014, filmmaker Tom Leveritt used an ultraviolet camera to show people their skin like they'd never seen it before. Now, you can do the same thing with the Sunscreenr: a tiny, waterproof UV camera that is meant to keep you slathering on sunscreen by showing you when you've used enough and where it's worn off.

Here's an interesting cautionary tip and something that we'd honestly never given a second thought to: it turns out that certain chemicals in sunscreen can damage cameras with polycarbonate resin bodies, so you'd better wash your hands the next time you put on sunscreen at the beach and decide to go out shooting afterwards.
