Best Body Sunscreen with SPF 30+: Banana Boat Ultra Defense SPF 50 Lotion

The contenders: Water-resistant or waterproof broad-spectrum sunscreens with an SPF of 30 or higher. Sun damage is the number-one cause of wrinkles and age spots, so not all the sunscreens were required to make specific anti-aging claims; instead they had to be formulated and packaged in a way that would appeal to women 35 and over.

Testing time: A single summer.

And the winner is... Banana Boat Ultra Defense SPF 50 Lotion ($10, amazon.com). Volunteers gave it outstanding marks for both preventing a sunburn and resisting water. Surprisingly, testers also preferred this product over lower-SPF options for ease of absorption, not feeling oily and greasy, and not causing any burning or stinging — three areas where lower-SPFs usually perform better. Testers noted that it was "easy to apply" and "felt rich and creamy on dry skin." They also liked the fact that it didn't have a strong fragrance. And considering the price ($10 for eight ounces), you never feel guilty about using too much.
