Since being diagnosed with estrogen and progesterone positive breast cancer, I have become very conscientious of the chemicals in foods and skin care products that I use. Recently, I came across this information from the Environmental Working Group (EWG) on sunscreens and protection. They say the best protection is a hat and a shirt. For their list of "Top Sunscreens" follow this link. (A rating of 0-2 is best and indicates the product has the lowest hazards.)
EWG states that mineral sunscreens have the best safety profile of products on the market today. However, they caution against using minerals in spray or powder forms. Minerals are stable in sunlight and do not appear to penetrate the skin while offering UVA protection. Another option is Mexoryl SX (ecamsule), but it’s sold in very few formulations. Tinosorb S and M are other good solutions but are not yet available in the U.S. For consumers who don’t like mineral products, EWG recommends sunscreens with avobenzone (3 percent for the best UVA protection) and without the hormone disruptors oxybenzone or 4-MBC. Scientists have called for parents to avoid using oxybenzone on children due to penetration and toxicity concerns.
Based on this article, I am tossing my old sunscreens (you can use their search function to search for sunscreens your currently have on hand) and plan to purchase Badger Unscented SPF 30. My printer is not talking to my computer and I would never remember that many brand names. I remember seeing the Badger product in my local health food store.

They also have ratings and information on cosmetics that I found helpful.
