Don't wait for the first crow's feet to appear before you reach for that little tube. "Even women in their twenties should be using a topical retinoid--unless they're pregnant or nursing," says Francesca Fusco, M.D., assistant clinical professor of dermatology at Mount Sinai School of Medicine in New York City.
Here's why: Retinoids, which contain vitamin A, are one of the most potent agents for preventing and reversing sun damage and signs of aging. And, says Hirsch, "they're the ultimate multitasker. They speed skin renewal by shedding dull, pore-clogging cells and increase collagen production to prevent wrinkles."Ask your doctor about a retinoid prescription or try an OTC, such as Roc Retinol Actif Pur Anti-Wrinkle Moisturizing Treatment--Night ($22 for 1 oz, drugstore.com).
