Most of us have heard the do's and don'ts of wrinkle prevention. Stay out of the sun, moisturize, don't smoke.

But here are a few tricks you probably haven't thought of yet -- new stay-young skin secrets from the experts at RealBeauty.com.

3 Smooth Secrets
Make these your mantra and you may be staring down fewer lines and wrinkles in the mirror:

• Eat soy. Early research suggests soy may help protect against -- and possibly even heal some -- photodamage caused by sun exposure. Try this easy and delicious recipe for Asian-Style Grilled Tofu with Greens.
• Have a cup of cocoa. Research shows that two of the antioxidants in cocoa -- epicatechin and catechin -- can help shield against sun damage and improve your skin's hydration and blood circulation. All of which can help lead to smoother looking skin. Try RealAge skin expert Dr. Amy Wechsler's favorite hot cocoa recipe.
• Sleep on your back. Sleeping with your face in the pillow every night can cause wrinkles known as "sleep lines," say folks from The American Academy of Dermatology. Perpetual side sleepers tend to get these fine lines on their cheeks and chin, while people who sleep facing down can end up with a more furrowed brow. Here's a facial expression that can affect your sleep.
