This weekend is Memorial Day, a day where Americans honor those who have died defending our country. It's also a three-day weekend that many use to take advantage of the approaching hot weather by spending time outside, either having a BBQ or lounging by the pool. So you've got to shield oneself from the elements, especially those harmful UV rays. For this bookmarking challenge, I'm asking you to find protective beauty items that you'd wear by the pool.

I'll start you off with Neutrogena Ultra Sheer Dry Touch Sunblock in SPF 55 ($9), because the lotion is light, not goopy or sticky, and the 55 SPF is an appropriate amount of protection. Also, the three-ounce container is perfect if you're getting on an airplane this holiday weekend.

Share your choices by bookmarking items from around the web and tagging them with the phrase Poolside Beauty. I'll feature your favorites here next Tuesday.
