Fats (three to four servings; one serving equals 1 teaspoon of oil, six nuts, or 1 tablespoon of ground flaxseed): Get adequate amounts of healthy unsaturated fats to keep your skin from getting dry and dull.
Water (at least eight 8-ounce glasses): "Hydrating the body from the inside plumps and erases wrinkles on the outside," says Elizabeth K. Hale, M.D., a clinical associate professor of dermatology at the NYU School of Medicine.
The right supplements: Even women who generally eat a well-balanced diet can fall short sometimes. "I'm a firm believer in taking a multivitamin as a backup," says David Bank, M.D., director of the Center for Dermatology, Cosmetic & Laser Surgery in Mount Kisco, New York. We love GNC WellBeing Be-Beautiful Hair, Skin & Nails Formula ($20; gnc.com), with antioxidants and nourishing amino acids.
Perfect your skin tone
The trick to minimizing brown spots and maximizing your glow is to use products that increase cellular turnover, says Macrene Alexiades-Armenakas, M.D., Ph.D., a New York City dermatologist. Sloughing every morning with a gentle granular scrub or a glycolic acid lotion—or at night with a retinoid (a vitamin A derivative)—is a good way to expedite exfoliation and expose newer, healthier skin. Try Neutrogena 14 Day Skin Rescue ($26; at drugstores), with retinol.
Pick the right products
Another key to healthy-looking skin is a proper morning and evening regimen. Here's what you should be using daily:
Cleanser: A gentle formula, such as Aveeno Ultra-Calming Moisturizing Cream Cleanser ($7; at drugstores), is appropriate for most skin types, a.m. and p.m.
Sunscreen: Use a broad-spectrum sunscreen with an SPF 15 or higher daily. We like Shiseido Future Solution LX Daytime Protective Cream SPF 15 ($240; macys.com), with hyaluronic acid.
