If you've arrived here via my guest post at The Beauty Brains, welcome! Please do comment or drop me a line to introduce yourself. The Brains and I have formed a mutual admiration society it seems. I've long read their site for the calm and clever debunking of beauty rumors and myths, balanced reviews, and advice. Their readers (perhaps you?) often write in asking about toxic ingredients such as lead and mercury ending up in cosmetics. But these chemicals and some even more sinister were once widely used and praised as beautifiers.
Poison never really goes out of style.
