“The chemical can get into our bodies more readily, and more of it. They are concerned, as are we, at that systemic absorption.”

"Zinc oxide is definitely the gold standard. Zinc oxide provides great broad-spectrum protection that protects against both UVA and UVB rays. Many people don't realize the SPF of sunscreens applies only to the UVB rays that cause sunburn. But the UVA rays also damage and age the skin.”

“Today, around a dozen emails arrive daily in an EWG inbox especially dedicated to company correspondence. Companies have told us that if they don’t score well, it will affect their bottom line.”

“The average American woman uses 12 beauty products a day and an average of 168 ingredients, which can make for a weird chemical soup on your skin. On top of that, many of those have never been adequately assessed for safety.”

“The fact that the agencies don’t test each produce item every year is problematic. And more importantly, the fact that the USDA and FDA aren’t testing for all the pesticides used in fruits and vegetables is a huge problem.”

“Sunscreens with oxybenzone should be avoided. Don't shun sunscreens in general. But lean toward using the mineral products available.”

“Under the current law, companies don’t have to prove that their ingredients or products are safe before they go on store shelves. The FDA has no authority to issue recalls or to force companies to issue recalls.”

“It can be hard to make a lifestyle change, but for almost every category of hair care, there are safer choices for black women. Look at all the products you are using and see how you can reduce your overall chemical load. As a consumer, it is important to vote with your wallet and push companies to develop safer options.”
