Vitamins A, E
Vitamin A for wrinkles
Best overall age-fighter
Proven to: Reduce wrinkles, fade brown spots, and smooth roughness. “There are more than 700 published studies on retinoids—they’re tried-and-true ingredients. Anyone who wants younger-looking skin should use one,” says Doris Day, MD, assistant clinical professor of dermatology at New York University Langone Medical Center.
Vitamin E for moisture
Proven to: Quell dryness by helping skin retain its natural moisturizers. Also, vitamin E’s potent ability to neutralize damaging free radicals has earned it the moniker “the protector.” A slew of skin care studies document its superstar status. In one, E significantly reduced the number of these unstable molecules created after exposure to cigarette smoke. Others show that when it’s used before UV exposure, skin is less red, swollen, and dry.
