Older complexions can look dull; youthful ones appear moist and even in texture. Look for formulas with light-diffusing particles and avoid powders, which can settle into fine lines and add decades.
Skin that seems to glisten naturally usually involves a little artificial sparkle. Apply luminizer to cheek and brow bones and to the bridge of your nose. We like Chantecaille's for fair complexions and Modelco Luminosity Shimmer Whip in Bronze ($32; sephora.com) for olive and darker ones.
Treat dry patches with a refined face oil. Pati Dubroff swears by Rodin Olio Lusso, which "smells divine and gives skin instant luminosity."

"Nothing is more aging than overly powdered skin," says makeup artist Molly Stern, who opts for mattifying primer instead. Try Smash-box's or Revlon Beyond Natural Smoothing primer ($13; drugstore.com).
Keep it sheer
Apply foundation only where needed, and choose a formula that can be layered for more coverage.
