The Purist: Julianne Moore
Though this ethereal Celtic beauty wouldn't look out of place wandering the Scottish moors, she's actually in her element strolling Downtown Manhattan with her two children, sans makeup. Here, the basics that keep her looking naturally gorgeous.

When not pursuing — and landing — some of Hollywood's most provocative leading roles, Julianne Moore lives simply — and "as green as I can." She has recently become an advocate for the Natural Products Association, whose mandate is to certify products as at least 95 percent natural, with renewable ingredients and nothing that's potentially toxic (like parabens). For Moore, it's personal. "My two kids have eczema, so I have to be vigilant about what goes on their skin. It helps when I'm shopping to see the NPA's seal of approval — the little green leaf."
