Put down the foundation (or shadow, or concealer — or whatever you use first in your makeup routine). Preparing the skin with a primer prior to makeup application is essential, according to Bass. "It creates a smoother surface for makeup to glide over and stay put," she says. "Especially when you're fighting wrinkles."

To get the smoothest surface possible, start with a clean face, and apply a rich moisturizer (Bass suggests Simple Replenishing Rich Moisturizer, $12.49). Then, dab on a nourishing eye cream, like Charlotte Tilbury Magic Eye Rescue, $60. Allow your skin to absorb the products for a minute or two before reaching for a hydrating primer. Bass suggests Laura Mercier Foundation Primer - Hydrating, $36, which helps seal in moisture and fills in fine lines and wrinkles.

To ensure your eye shadow remains locked in place and doesn't get lost in the crevices of your skin, prep your eyes with eye primer (try Urban Decay Potion Primer, $20). Give it about a minute to dry before applying your makeup.

Because problems like fine under-eye lines and dark circles become pronounced with age, it can be tempting to combat them by layering more and more product — but this may do more harm than good. "Too much cakey concealer is a huge no-no, as piling it on just accentuates fine lines," Bass says.

One way to avoid a cakey-looking finish? Apply concealer with your fingertips instead of a sponge. "A sponge will likely leave a cakey finish on mature skin," says Joey Maalouf, celebrity hair and makeup artist, and co-founder and creative director of the Glam App and ISH Beauty. Just lightly dab the product on your skin with your finger after applying foundation.

Similarly, too much setting powder can also work against you, according to celebrity makeup artist, Taylor Babaian. "The combination of liquids with powder sit in fine lines and make them appear more evident," Babaian says.

To set your concealer, Maalouf recommends using a light and colorless powder, like M.A.C. Prep and Prime Transparent Finishing Powder, $27, or better yet -- a makeup setting spray, like Urban Decay All Nighter Long-Lasting Makeup Setting Spray, $30.

According to Babaian, the key to hiding dark circles, which is a problem for a lot of mature eyes, is all in color correcting.

"You see discoloration around the eyes no matter what the skin tone," she says. "The shadows of the [wrinkles] often appear gray, so use a slightly pink-based concealer for light-to-medium skin tones, and peach for medium-to-tan." These peachy-pink products help neutralize dark circles, as well as dark spots caused by the sun. Babian recommends applying concealer to the inner corners of the eyes with a synthetic brush (try BH Cosmetics Brush V7 - Vegan Concealer Brush, $5.50). This will even out discoloration all around the eye, and give your eyes a bright wide-awake look.

When selecting a concealer, grab a color two shades lighter than your skin tone. If your skin is ultra-thin under your eyes, Babaian suggests Yves Saint Laurent Touche Éclat, $42, as it's sheerer than heavy concealers and won't look so caked-on. She loves Clé de Peau Beauté Concealer, $70, for light to medium skin and Bobbi Brown Creamy Concealer, $27, for darker skin tones.

When it comes to eye shadows for mature women, not just any old palette will do. There are definite dos and don'ts, according to Bass. "You really want to avoid heavy powders around the eyes, as they can settle into fine lines and wrinkles and exaggerate them," she says. "They're also really hard to blend on crepey lids and can look too harsh." Instead, reach for a sheer powder or cream shadows, which blend easily with a makeup brush or fingers and look more natural on aging skin. Bass recommends Dior 5 Couleurs Eyeshadow Palette, $62.

Another type of eye shadow to avoid? Shimmery or metallic finishes. Iridescent shadows — as pretty as they may be — bring out wrinkles around the eyes and can make them look uneven and patchy when they settle into the crevices of the skin, according to Bass.

For a little sparkle, apply a satin finish nude shadow on the inner corners of the eye and down the center of the lid. This adds dimension and a soft glow without exaggerating fine lines. Try the Shiseido Luminizing Satin Eye Color Trio, $33.

We can't blame you for wanting to make a statement, but you may not want to do it with in-your-face eye shadow colors. "Bright, poppy or superdark colors can look garish, harsh and really aging," Bass says. "Neutrals work well on anyone, so opt for colors like nude, beige, peach or brown."

To open up the eye, apply a neutral shade, like beige or peach, on the lid and a deeper brown or taupe in the crease, and blend well. "The outer corners of the eyes fall as you get older. Apply the eye shadows in a 45-degree angle [at the outer corner of the eye], so that the outer corners appear lifted, and avoid applying any eye shadow directly underneath the brows," Babaian says. She recommends using the Sonia Kashuk Eye Couture Palette, $19.99, as it includes a range of neutrals.

If you still want a splash of color on your lids, brush on a soft wash of color (think: soft plum, blue-grey or gold) on the upper lid. Then, apply your crease color (a deeper brown or taupe) in a thin line along the lower lash line, and lightly smudge with a soft smudging brush or your fingertip to avoid any harsh lines. This will help make your eyes pop.
