It's not always easy to remember how long you've been exposed to harmful UV rays, especially if you're passing time playing at the beach, taking in an outdoor workout or hike, or chasing after your kids at the park.
These I Will Reflect bracelets change color (from white to purple) when exposed to harmful UV rays. Plus, I think they're kind of cute too! For $5, you can't beat the price and proceeds go to the Skin Cancer Foundation. Get yours at SpaFinder.com.
