Beautiful Earth, Healthy You

When browsing the beauty aisle, Sophie says to look for "paraben-free" products, like those pictured above. "Parabens are preservatives, and they can be hormone disrupters," she says. "Parabens are in everything. They're in shampoos, body lotions, face creams. … There's conflicting advice, but I stay away."

Sophie says brands like Method are a good option, but if you're not sure whether a product is paraben-free, just check the ingredients list. Parabens are always present if "ethyl parabens" or "methyl parabens" are listed.
