- Just chill. To combat puffiness, you need the right tools: New gel-based eye serums come with cooling metal applicators. "The hydrating formula perfectly preps skin for makeup," Kahler says. "Massaging it in with the chilly tip constricts blood vessels and diffuses fluids, which will help deflate bags."Try: Lancôme Génifique Eye Light-Pearl, $68; lancome-usa.com.
- Take cover. A concealer with lightreflecting particles is like a cup of coffee for your face. "It not only camouflages dark circles, it also brightens the entire eye area," Kahler says. Be sure to work the product into your inner corners and up the sides of your nose. "Darkness in this often-missed spot can make you look haggard," she says.

- Go neutral. Lack of sleep can cause redness on the inner rims of your lower eyelids. Lose the unwanted color with a fleshtone liner. Then apply a shimmery taupe shadow on upper lids up to the crease. "Skip deeper shades if you're feeling sleepy—they can make eyes look sunken," Kahler says.Try: Rimmel London Scandaleyes Waterproof Kohl Liner in Nude, $4.49; drugstores.
- Lash out. Your first objective with lashes is coaxing them to curl. "This directs the tiny hairs up and out, making the eye area look larger," Kahler says. Exaggerate the effect by selecting mascara with a detailing tip—a bulb with extra bristles on the end of the wand. Apply one coat with the flat part, then go back and fan out lashes with the tip.Try: Benefit They're Real! Mascara, $23; benefitcosmetics.com.
- Mouth off. An eye-catching lip color can do wonders
for a tired face. Kahler likes tones with an orange tint. They help cancel out any blue under the eyes. Try: Sonia Kashuk Ultra Luxe Lip Gloss in Coveted Coral, $8.99; target.com.
