Cosmetic Chemistry Syllabus

Required Reading: The ingredients list on the back of your favorite beauty product.

Homework Assignment: Research each chemical for toxicity and side effects.

Surprised by the percent that fails to make the grade? Take a lesson from L.A. entrepreneur Gregg Renfrew. When her passion for clean living turned up zilch in the cosmetics department, she recruited an eco-conscious team, including a green chemist, to create Beautycounter, a collection of effective but nonharmful skin care products.

Safety’s guaranteed in standouts like the moisturizing night cream (infused with organic coconut oil), hydrating rosewater spray, and scented face oil (available in jasmine, ylang-ylang, and calendula).

In need of extra pocket change? Sign up to sell the line locally (consultants take home up to 35 percent of the profit).

Which brings us to Nest Eggs 101.

Available at beautycounter.com, $18-$68.
