You'll know you're a candidate "if you have lines and wrinkles around your eyes or on your brow that are caused by expression movements" and that remain visible when your face is at rest.How do you keep neck skin tight? (Most searched in California and Maryland)Celeb-beloved Beverly Hills dermatologist Harold Lancer, MD, says that "the neck is one of the most asked-about areas of the body for women." It's also notoriously one of the hardest to treat once signs of aging, such as sagging or wrinkling, begin to show.

She then eliminates darkness with either a sheer foundation or a pigment-rich concealer, depending on the zone of the face. "The skin on the forehead is really thin, so you need less makeup there," she says. For creases around the eyes, "I apply the concealer at a 45-degree upward angle, which will cancel out the wrinkles that point downward, as well as draw the eyes up and change the angles of the face," Chang-Babaian says.

(Most searched in Connecticut)Packed with omega-3 essential fatty acids, cold-water fish\u2014wild salmon, sardines, herring, trout\u2014help boost skin's bounce.
