It's our mission at the Environmental Working Group to use the power of information to protect human health and the environment.

Often, that means building databases. EWG's data gives you practical solutions to protect yourself and your family from the health risks we all face from everyday exposures to myriad industrial chemicals.

In 2004 we launched Skin Deep, an online safety guide for cosmetics and personal care products. Our aim was to fill in where companies and the government leave off: companies are allowed to use almost any ingredient they wish, and our government doesn't require companies to test products for safety before they're sold. EWG's scientists built Skin Deep to be a one-of-a-kind resource, integrating our in-house collection of personal care product ingredient listings with more than 50 toxicity and regulatory databases.

Now in its fourth year and third major update, our Skin Deep database provides you with easy-to-navigate safety ratings for nearly a quarter of all products on the market — 22,694 products with 6,777 ingredients. At about one million page views per month, Skin Deep is the world's largest and most popular product safety guide.
