1Cartoonish brows.
Getty ImagesWorse than the sparse arch is a harsh, overdone brow, says Linter. The culprit may be the wrong tool, like an eyeliner pencil that is soft and goes on too strong. "A brow pencil is designed to be hard and go on softly, so your brows look natural," Manhattan-based makeup artist Sandy Linter says. Try IT Cosmetics Brow Power Universal Brow Pencil ($24, sephora.com).

2OD'ing on foundation.
adamkaz//Getty ImagesAs hormone levels dip and your skin gets drier, you may reach for a cream foundation. Not so fast: "Thicker, creamier formulas are usually made to provide fuller coverage, which means they're packed with more pigment," says Portland-based makeup artist Jessie Powers. "And pigment is basically powder."
If you like a creamy formula's coverage, try it with a richer face moisturizer or a hydrating primer, like Laura Geller Spackle Under Make-Up Primer ($32, ulta.com).

3Foundation that's too pale.
laflor//Getty ImagesSkin grows more pallid with age, so if you're wearing a matchy-matchy foundation, it can leave you looking pasty. (Yep, time to ditch the rule that says you should match.) Linter puts life back into her skin with a slightly warmer tone. You can also just mix an exact-match shade with the next darkest hue on the back of your hand, and then apply with a foundation brush.

4Caked-on concealer.
Getty Images"As soon as you've reached the years when you really need a concealer, it can let you down by sinking into lines," says Linter. To keep concealer from drawing attention to wrinkles, apply it only on the inner halves of your under-eyes to cover up any darkness. Or just skip the concealer, as Linter often does, and use a brush-on highlighter pen like Sephora Collection Smoothing & Brightening Concealer ($14, sephora.com).

5Streaky blush.
PeopleImages//Getty ImagesForget stroking blush from mouth to ear; that technique only emphasizes gauntness as you get older, says Powers. An instant trick to lift cheeks: Swirl blush ever so slightly higher on the apples.

6Highlighter everywhere.
puhhha//Getty ImagesAvoid a cartoonish look and only brush your highlighter in specific, face-flattering areas. "Wearing highlighter in the wrong place can give you the opposite of a luminous effect," says makeup artist Jami Svay. "Use it where the light naturally touches your face, like the brow bone, bridge of the nose and along the cheekbones."

7Overdone eyes.
Christopher Robbins//Getty ImagesOily lids can spell ruin for eyeshadow, but piling on extra will only make your eyes look weighed down. Your best bet: First apply a thin layer of a clear primer like Urban Decay Anti-Aging Eyeshadow Primer Potion ($24, sephora.com).

8Muddy eyeshadow.
Westend61//Getty ImagesIf brown and bone are your go-to eyeshadows, take note: "Brown has yellow or red pigments in it, either of which can actually make eyes look tired," says makeup artist Laura Geller. Also be careful with once-"safe" shadows like bone; they're often too light to cover discoloration on lids. Your new go-tos: sage and jewel tones.

9Jagged, uneven liner.
JGI/Jamie Grill//Getty ImagesAvoid tugging at the outer corners of your eyes, says Geller. "This can cause skin to crinkle, and your line will not be as smooth." Instead, point your chin up and look down, so your lids are half-closed but you can still see them, and use a liquid liner, like Lancôme Artliner ($31, sephora.com), which won't pull at skin.

10Droopy lashes.
Lena Clara//Getty Images"Lashes can make eyes look more youthful and awake," says Powers, but one common mistake is skipping the eyelash curler. Use it to curl each lash at the root, holding for 15 seconds.

11Wearing the same old lip colors.
Getty ImagesIt's the easiest way to refresh your look. If you've been wearing neutrals since the '90s, try red. If you've been loyal to red, try a pink. Play with the color, but go easy on texture. "Anything that's severe — a lipstick or hairdo — will age you. So wear a red, but a sheer one," says Linter.

12Lipstick that bleeds.
PhotoAlto/Frederic Cirou//Getty Images"Extra lipstick migrates, especially as the definition of the lip's border softens with age," explains Powers. So, instead of applying color straight from the tube, apply with a lipstick brush, like the e.l.f. Retractable Lip Brush ($3, ulta.com). Dab on the center of your lips, and then spread it to the corners.
