Once a cover girl for Maybelline, Maran launched a line of natural or "eco-chic" cosmetics in 2007. Maran says her lipsticks, mascara and other beauty products — which come packaged in biodegradable corn-based plastic — are organic and free from the parabens and petrochemicals found in conventional makeup. While some critics remain skeptical that the line actually lives up to Maran's green ideals, they can't argue with her charity model: 1 percent of profits from her new Bear Naked makeup wipes goes to the National Resource Defense Council's Polar Bear SOS initiative.
