For those of you who can't imagine going a day without makeup, be aware: there is no federal regulation to ensure that the chemicals in lipsticks, blush, mascara and other products are safe for public use.

So how do you know your makeup won't harm your health? One way is to check out the Campaign for Safe Cosmetics. The organization has asked cosmetic companies to sign a pledge promising "to not use chemicals that are known or strongly suspected of causing cancer, mutation or birth defects in their products."
