A Gleam in Your Eye

Liner and mascara not only create contrast between the eyes and skin, but also help the eyes appear larger. "Trace an espresso brown or smoky gray pencil as close to the upper lash roots as possible to make the base of the lashes look denser," says L.A. makeup artist Pati Dubroff. Then use a volumizing mascara on the upper lashes to add lushness (try L'Oréal Paris Voluminous Miss Manga Rock Mascara). For the lower lashes, Dubroff prefers a thin formula, like Surratt Pointilliste Mascara. She lines the inner lower rims with a flesh-tone pencil (such as Chanel Le Crayon Khôl) to increase brightness.

Arch Support

To enhance brows, makeup artist Laura Geller, founder of Laura Geller Beauty, uses a dry pencil instead of a creamy one (get Marc Jacobs Beauty Brow Wow Defining Longwear Pencil) because it adheres better to skin: "Choose taupe—you can make it lighter or darker depending on how much pressure you apply," says Geller. Using short, fine strokes, fill in any sparse patches and then comb through with a spoolie brush.

Ring Tone

A fading limbal ring may seem beyond your cosmetic control, but even that can be cheated now: 1-Day Acuvue Define contacts mimic the appearance of a sharp limbal ring without changing the color of the iris. (They're also available without vision correction.)

Finishing Touch

Mask complexion concerns with either a tinted moisturizer, like Olay Total Effects Pore Minimizing CC Cream, or a heavier full-coverage foundation, such as Laura Geller Baked Liquid Radiance Foundation. Whatever you choose, "if your goal is to appear youthful, it's really important to stay away from powders," says Dubroff. "You want skin to have a dewy finish." Begin by applying a liquid or a cream with a brush in the center of your face (under the eyes and around the sides of the nose and mouth). "That's usually where the color is most uneven," she says. Work out toward the perimeter with your brush. Go over any blemishes with a more opaque concealer (we like Maybelline New York Master Conceal by Face Studio), using a stippling motion with your fingertip, says Geller. To hide dark under-eye circles, Dubroff prefers concealers with built-in brushes (try Philosophy Hope for Everywhere) because they're easy to work with. "I start at the inner corner of the eye and go about a third of the way across beneath the lower lashes," she says. "Then I apply concealer at the outer corner and blend the two to meet, so I don't end up with a thick layer."

Cheek Chic

Mimic full, flushed cheeks by dabbing cream blush (Lancôme Blush Subtil Crème in Corail Alizé is good) directly on the apples. "The effect is like you've pinched that area to bring the blood flow back," Dubroff says. "If you have a warm or olive skin tone, stick to peach; if your skin is on the cool side, try a pink."

Smart Mouth

All you need for gorgeous lips is liner and tinted balm, according to Dubroff. "For both, choose a color two shades darker than your natural lip—a warm berry or a soft rose," she says. Avoid orange tones, as they can emphasize any yellow in your teeth. Fill in lips with pencil (such as Elizabeth Arden Beautiful Color Smooth Line Lip Pencil), and then coat with tinted balm (like CoverGirl Jumbo Gloss Balm Sheers).

To keep your teeth as white as possible, limit your consumption of staining beverages, like red wine, tea, and cola, which penetrate the enamel, and eat fruits and veggies high in fiber, such as apples and raw carrots, which clean teeth's surface. An arresting smile requires more than just whitening, however. Over time, your teeth may become shorter from chewing and grinding, says New York City cosmetic dentist Marc Lowenberg, DDS. If you notice you're grinding, speak to your dentist, who may suggest wearing a night guard.
