10 Toxic Ingredients Pregnant Women Should Never Use in Their Beauty Routines

Commonly found in: sunscreen, moisturizer, and aftershave.

Why you should avoid it: Oxybenzone can act like estrogen in the body, and it's been shown to alter sperm production in animals. It is also associated with endometriosis and allergic reactions. The skin absorbs oxybenzone in significant amounts when we use sunscreen that contains it, and a study from the Centers for Disease Control and Prevention (CDC) detected it in more than 96 percent of the US population.

Other troubling studies have found traces commonly present in mothers' breast milk. Beautycounter's Renfrew warned: "Just because a sunscreen is marketed towards children, doesn't necessarily mean that it's safer."

Products without oxybenzone to try instead:

• Mineral sunscreens like Derma E Antioxidant Natural Sunscreen SPF 30 Oil-Free Face Lotion ($20)
• First Aid Beauty Ultra Repair Cream ($30)
