3. Master Disguise
You notice: When you use enough concealer to cover up dark circles and puffiness, you end up looking like an owl.
Key moves: Apply foundation before concealer to mute dark circles and puffiness. "Foundation is less opaque than concealer and gives more uniform coverage," says Geller. Afterward, lightly dot a skin-matching concealer where you still see discoloration. It will blend in more easily over the base. Try E.L.F. Corrective Concealer ($3, eyeslipsface.com), a set of four mix-and-match colors that lets you create the exact shade you need.
4. Pencil It In
You notice: Due to looser skin, your once-flawless liner application now looks like an EKG tracing above your lashes.
Key moves: Line your top lids using a soft — but not too soft — pencil that won't tug at skin. Try Benefit Automatic Eyeliner Duo Pencil in Downtown Brown ($20, sephora.com). Or, wet the bristles of a liner brush and dip it into shadow. Then give a little tautness to the lid by gently pulling the corners back toward the temples, says Carmindy, a makeup artist and the creator of Sally Hansen Natural Beauty. Apply the liner in little dashes across the upper lashes, then connect the line with a smudger, cotton swab, or brush. Avoid thick bands of liner; they close up the eye area. "The tighter the liner hugs your lashes, the more bright-eyed you will look," says Geller.
5. Play with Shadow
You notice: Eye shadow disappears into your lid folds by midday, forming unflattering creases and exposing discoloration.
Key moves: Lid primer can even out the surface and lock in shadow. Consider one of the new two-in-one shadow-plus-base options, such as Too Faced Lock Down Ultimate Creaseless Cream Eye Shadow in Bedroom Eyes ($18.50, sephora.com), or buy a separate primer that goes under your favorite formula. Your shadow color should relate to your skin tone: Beige, taupe, and ivory are all good options once you hit your 40s. Neutrals with subtle — repeat, subtle — luminescence, such as Mark Making Eyes Eyeshadow Duo in Down to Earth ($6, meetmark.com) will have the most eye-brightening effect. Sweep the color up to the crease; you can always add more depth by placing a deeper shade directly in the crease.
