Whether it's a picnic, a beach trip, or baseball game, if you're going to be outside this Memorial Day weekend don't forget to wear  sunscreen and a lip balm with SPF. Lips are a commonly overlooked area when it comes to sun protection, even if you always put sunscreen on your face.  But our lips are vulnerable to damage from the sun's ultraviolet (UV) rays. Not only do they have a thinner protective top layer of cells compared with the rest of our skin but the bottom lip also tends to protrude slightly, so it can easily catch the sun's rays.

In our latest sunscreen tests, we tested five lip balms labeled SPF 30 or higher. All but one is claimed to have water resistance for 80 minutes. Though each received an Excellent UVA score, none of them met their SPF claim in our tests. Banana Boat Sport Performance Lip Balm SPF 50, $2.50, came closest to an SPF 30, providing an SPF 28 in our tests. Here's how the others performed.
