Like many of you, I’m a wife and mom—and, like many of you, I didn’t know what I didn’t know. As I applied sunscreen, lotion, and any number of beauty products on myself and my kids, I never thought for a second they might not be safe: After all, I thought, we live in a country that regulates everything. So imagine my surprise when I learned that when it comes to the personal care industry, that’s simply not the case. Companies are allowed to use harmful ingredients and make their own judgments about safety.
