The Right Skin Care for Every Age

"It's really important to begin using sunscreen as part of your daily regimen in your 20s," notes NYC dermatologist David Colbert. Shield skin from the sun's wrinkle-causing rays and fight free radicals with an A.M. application of Shiseido the Skincare Day Moisture Protection Enriched SPF 15, a creamy moisturizer that also comes in a lighter formulation for combination complexions.

The stress of juggling a busy life and career or starting a family can take a serious toll on your skin. "Acne can appear again in your 30s or even for the first time as a result of hormonal changes and work-related stressors," says Colbert, who recommends glycolic or salicylic acid to keep breakouts at bay. Use Aveda Outer Peace Acne Relief Pads each morning and night after cleansing. They contain a natural (but equally effective) form of salicylic acid derived from wintergreen oil.

Hormonal changes can leave your complexion dry and flaky. "Pick a product with hygroscopic moisturizers, which bind to water beneath the skin's surface to plump it from within," says Colbert. Try iS Clinical Youth Complex, a serum with hyaluronic acid, a hygroscopic molecule. It keeps skin dewey all day. iS Clinical Youth Complex ($135).

"Loss of volume in the face can cause hollows and dark circles under your eyes," explains Wexler. Use an eye cream that simultaneously lightens circles and plumps skin. We like L'Oréal Paris Wrinkle De-Crease Collagen Filler Eye Illuminator ($19.99).

It's never too late to treat uneven skin. "Pick a moisturizer that lessens sunspots while reducing dryness and sagging," says Wexler. A good investment: La Prairie Cellular Radiance Concentrate Pure Gold, which lightens overpigmentation and boosts radiance with tiny flecks of 24-karat gold.
