GoodGuide Sunscreen Ratings: the Winners and Losers

When it comes to sunscreens, are all products essentially equal? Not by a long shot! Recently, GoodGuide, an online source of information on consumer products, reviewed and rated more than 800 sunscreens with an SPF of 15 or above to find the ones that ranked best -- and worst.

All sunscreens in the survey were reviewed using three factors of increasing importance to consumers: personal health, concern for the environment and social responsibility. Kinesys SPF 30 Sun Protection Stick outscored all the other sunscreens as rated by GoodGuide, while Playtex's BioSun Maximum Sunblock Lotion, SPF 45 was rated worst.

It's GoodGuide's goal to help consumers find healthy, green, ethical products based on scientific ratings, and its experts have rated more than 100,000 consumer goods -- including food, personal care and household products -- based on the health, environment and society factors.
