How to Fake a Good Night's Sleep

"Genetics are the most common cause of dark under eye circles, but dehydration, poor nutrition and lack of sleep can cause them as well," says Up All Night makeup artist Heather Koontz. "I use the Givenchy Mister Instant Light corrector pen on Christina?s under eye area because it's quick, it gives great coverage, and a little goes a long way." Is there a way to lighten dark circles without using makeup? "There are many products. Do they all work? No." Koontz says. "Get samples, until you find the one that works for you. I like Clinique's Even Better Eyes Dark Circle Corrector."

"Finding the perfect lip color takes time and experimentation, and just because a color looks good on your best friend doesn?t mean it will look good on you," says makeup artist Alex Proctor. "I use Chanel?s lip colors on Maya Rudolph (Ava Alexander) because they're rich and have a good staying power."

No time to lather, rinse, repeat? "Work dry shampoo through your hair to add volume, [if you have time,] add some soft waves using a 1-1/4 inch curling iron. Then just tease the crown area a bit and pull it all back into a ponytail," says hairstylist Romy Fleming, who creates polished yet simple updos for Applegate's character Reagan. "For a little extra touch, French braid your bangs off to the side."

"I start with a great eyelash curler," Proctor says of the 3-step method she uses to play up Rudolph's eyes. "Then I apply Bobbi Brown?s no smudge mascara, and finish with Mac?s Kajal eyeliner in Graphblack." No time to do all three? A quick crimp with the lash curler works wonders.

"Less (if any) is more," Koontz says of her two-minute makeup regimen. "Apply a little powder foundation and some waterproof mascara, and dab cream blush on the apples of your cheeks." Finally, skip the lip color in favor of a moisturizing balm. "Clinique's Chubby Sticks come in lots of colors," says Koontz. "Christina and I both love them."

Shaping your arches does wonders for your face, but unless you know your way around a pair of tweezers, Koontz advises against doing your brows at home. "Many womens' brows need to be tamed, but if you are not sure how to groom them yourself, it's worth getting them done at a salon," she says. As for daily maintenance, "eyebrow gel is amazing. It gives staying power to the shape and adds a little color."

The secret to Rudolph's on-set glow? Products that even out her skin tone without looking caked-on. "I start with Makeup Forever liquid makeup," says Proctor, who mixes 2 shades together to match the actresses complexion. "I follow that with loose powder and top it off with Nars blush in Gina."

"Turn your head upside down and blow dry until your hair is semi-dry, then flip back upright and dry your hair in sections, using a round brush and working your way up to the crown of your head," says Fleming, who recommends using a thermal protectant spray to guard hair against damage caused by heated styling tools. "Once it's dry, apply either Alterna Bamboo Luminous shin mist or Moroccan Oil Glimmer shine spray very lightly to the ends for added smoothness."

According to Koontz, five products and 5 minutes are all you need. "First, apply powder foundation all over your face. Then, using an eye shadow palette that has light, medium and dark shades, sweep the lightest shadow from inner to mid-lid, add a little of the darkest shade to the outer corner at the top of the lid, use the medium shade on the lower lid and blend. Touch up your eye liner, then apply blush on the apples of your cheeks and blend it back over your cheekbones," says Koontz. "Lips are the last touch, go for a darker color like berry or burgundy and use a big lip pencil like the ones from Nars."
