The best things for your skin come from the aisles of your supermarket.
"Increasingly, studies are finding links between certain nutrients and wrinkle reduction, radiance, and acne prevention," says David Bank, MD, a dermatologist in Mount Kisco, New York. Fitness Magazine shares 10 ways to nourish your skin from the inside and out.
Prevent Wrinkles with Yogurt
The protein you get from eating dairy helps skin become firmer, so it's more resistant to lines, Dr. Wu says. Greek yogurt is especially beneficial. "The protein content is often double that of regular yogurt," Dr. Perricone adds. Eat a single serving daily to make your complexion smoother, and apply Korres Yoghurt Instant Soothing Gel ($38, sephora.com) to calm irritated, dry, or sensitive skin.
Protect with Pomegranates
They're packed with polyphenol antioxidants, Dr. Perricone says. Polyphenols fight free radicals and regulate skin's blood flow, giving it rosiness. One pomegranate or a few glasses of juice daily should do the trick. When applied to skin, the fruits' antioxidants help smooth lines and moisturize, Dr. Bank says. Reduce wrinkles with Grassroots Research Labs Pomegranate Super Anti-Oxidant Cream ($35, kohls.com).
Soften Skin with Walnuts
"Walnuts contain omega-3 essential fatty acids, which can improve skin's elasticity," Dr. Bank says. The nuts are also loaded with copper, a mineral that boosts collagen production. Snack on a handful of walnuts each day to improve your complexion's texture, and slough tough calluses with True Blue Spa Smoothing Foot Scrub Toe the Line ($15, bathandbodyworks.com). The ground walnut it contains acts as an exfoliant.
Fight Crow's-Feet with Peppers
"Women who eat green and yellow vegetables regularly tend to have fewer wrinkles, especially around the eyes," Dr. Wu says. Also, studies found that carotenoids -- the antioxidants in yellow and orange veggies -- can decrease skin's sensitivity to the sun, Dr. Bank says. Aim for about two cups of peppers daily.
