In Harper Bazaar's latest Fall Fashion issue, the magazine asked eight of the most iconic Nineties supermodels -- Amber Valletta, Shalom Harlow, Kristen McMenamy, Helena Christensen, Nadja Auermann, Cindy Crawford, Claudia Schiffer and Tatjana Patitz -- to wash off the makeup and go au naturale for Peter Lindbergh's lens.

Perhaps not a huge surprise, even with a few wrinkles here and there, they all still look supremely gorgeous -- especially 43-year-old Crawford.

Her anti-aging secret? "Women forget to take care of their décolletage, and it shows their age," she tells the magazine, adding that she protects her chest and complexion with her own skincare line with Jean-Lous Sebagh, Meaningful Beauty.



Schiffer, on the other hand, said that cutting dairy out of her diet helped her skin look its best. "Fresh carrot or apple juice and water with lemon and ginger help give my skin a healthy look," she says.

Harlow also looks to the fridge for her beauty fix. "I love putting yogurt and egg whites on my face," she confesses. "It's so moisturizing and soothing."

Pick up the September issue of Harper's Bazaar -- with youthful covergirl Leighton Meister -- for more supermodel beauty tips.
