I put a bunch of them to the test. Here are my top skin-saving picks!
Best for Hiking: VMV Hypoallergenics Armada Sport 70 is super lightweight and stays put -- even in the stickiest of climates. I plan on using this one all summer, even if I'm just hanging out in the park.
Most Convenient: It's a tie! I love the very portable Mission Skincare Anti-Sting Sunscreen SPF 30+ Facestick for my lips, ears and around my eyes (my mom uses it on her whole face), but for reapplying on the go, nothing beats Aveeno Positively Ageless Sunblock Spray SPF 50.
Best for Lounging on the Beach: Without a jungle canopy to protect me, the sun was relentless. Neutrogena Ultra Sheer Dry-Touch Sunblock SPF 100+ saved the day (and my skin).
Best for Seaside Happy Hour: The thing about the tropics is that after you shower for dinner you look outside and realize it's still sunny. But who wants to put sunscreen on all over again? PCA Skin Perfecting Face & Body Hydrator SPF 30 is more like a lotion than a sunblock and sinks right in.
Best Double Duty: Avon Skin-So-Soft Bug Guard Plus SPF 30 Sunscreen Spray protects against sunburn and insects. 'Nuff said!
Best Anti-Aging: You need sunblock to protect against damaging rays, but if you want a little extra boost, try GliSodin Skin Nutrients Advanced Skin Brightening Formula supplements. Dr. Oz (of "Oprah" fame) heralded lycopene to protect against sun damage and these pills contain it -- plus other anti-aging nutrients to help reverse damage.
