Is mineral sunscreen effective?

According to EWG, zinc oxide and titanium dioxide lotions are among the best choices on the American market. Mineral sunscreen provides strong sun protection with few health concerns and does not readily break down in the sun. For more information, please see EWG’s Sunscreen Guide.

Because no sunscreen is completely waterproof—and it is important to limit the amount of any kind of sunscreen getting into our water systems and ocean—the first line of defense in protecting your skin is avoiding peak times (between 10:00 am and 2:00 pm), seeking shade, and wearing protective clothing such as hats, long-sleeved shirts and sunglasses or rash guards and wetsuits in the water.
