6. Get Fringe Benefits
You notice: Putting thickening mascara on thinning lashes makes you look a little too Tammy Faye — not the effect you're after.
Key moves: Once you hit your 40s, you want your mascara to be more lengthening than volumizing, says makeup artist Sandy Linter, Lancôme's Beauty at Every Age expert; heavy, clumpy lashes are not youthful. Choose a formula that's also water-resistant to keep mascara from smudging and flaking. One splurge that delivers a flawless fringe: Lancôme Ôscillation Water-Resistant Mascara ($34, department stores). Mimic its battery-powered lash-lengthening and defining tricks by pressing your own mascara wand against the base of your lashes for a few extra seconds, then jiggling the brush back and forth as you draw it out to the tips. And always curl lashes first. "I'm shocked how many women don't take advantage of this eye-opening, younger-in-a-snap tool," says Freedman.
7. Support Your Arches
You notice: Your brow hairs are getting more sparse. "If you've been waxing your brows for years, the hairs may have simply stopped growing back," says Dr. Marmur.
Key moves: Counter thinning brows by shading them with a powder or sheer pencil one notch lighter than the hair (note: light blond or white arches should be made a touch darker instead). Try Mally Brow Beauty Brow Fix in Taupe ($25, qvc.com), a self-sharpening pencil infused with polymers that create volume and tame brows. But use pencils and powders sparingly: "You want to add definition to your features, but not that aging 'filled-in' look," notes Freedman.

8. Blush Easily
You notice: You brush on blush, as usual, to put natural-looking color in your cheeks — and end up with clownish streaks instead.
Key moves: Switch from a powder to a translucent cream blush to give you that lit-from-within effect. Opt for fresh pinks and peaches that restore your natural glow. They're often more sheer going on than they look in the package. Try CoverGirl & Olay Simply Ageless Sculpting Blush in Lush Berry ($11, drugstores). "Anything see-through that blends into your skin is more youthful," says Carmindy. To avoid streaks, Dempsey suggests placing a dot of creamy color in the center of the apple of each cheek, then moving it in a circular motion with your fingers until it looks like a healthy flush.
