Tired of skin products that sound too good to be true -- and are? Then check out the only proven wrinkle reducer on the market: retinoids.

Retinoids can do amazing things, according to Dr. Amy Wechsler, dermatologist, psychiatrist, and author of RealAge's new skin-care book, The Mind-Beauty Connection.

Beauty in a Bottle
Better skin can come in a bottle -- well, actually, a tube. But it's a tube your doctor has to prescribe. Wechsler recommends two kinds of retinoids in particular -- tretinoin (Retin-A, Avita, Renova) and tazarotene (Tazorac, Avage). "These are FDA-approved, rub-on treatments that rank high on my list of skin-renewal candidates," writes Wechsler in her new book. "Prescription retinoids can transform your skin, smoothing wrinkles, unclogging pores, lightening superficial brown spots, and improving the texture of the skin. It takes several weeks to start seeing results, but it's so worth it." (Learn more about our new RealAge skin-care expert.)

Ask your dermatologist if retinoids are right for you.

Retinoids are vitamin A derivatives, and vitamin A can help your skin from the inside out as well as the outside in. Sweet potatoes are a great source of this skin-friendly vitamin. Here are a few more antiwrinkle foods to stock up on:
