Faking It: A Good Night's Sleep

Celebrity esthetician Renee Rouleau suggests that you avoid wearing yellow-based colors (like mustard, olive green and khaki) because they can make the skin appear sallow.

Use a pink-toned cream blush to add a natural-looking glow to your face. Plus, the cream formula adds a dewiness that you'll be missing if you haven't been sleeping enough.

The first step to masking those inevitable dark circles is to apply a skin brightening eye cream with stable vitamin C, says celebrity esthetician Renee Rouleau. Use circular motions when applying to stumulate stagnant blood flow that can contribute to darkness.

Next, you need to apply a good concealer to those circles. Don't choose a shade that is too light, or the dark circles will continue to show through. Dab the product lightly under your eyes. Start with just a little and add more as necessary so as not to cake on product.

Adding a highlighter or shimmery white cream in the corners of the eyes or along the bottom lids will instantly brighten and widen your tired eyes.

Renee says to ditch the cucumbers when it comes to your puffy eyes. They don't contain any miraculous puffiness-reducing properties. Since it's the cold that reduces puffiness, you can grab anything out of the refrigerator (like ice or a bag of frozen peas) and it will do the trick — as long as it is held on the area for at least 10 minutes.

Drinking peppermint tea is known to boost blood circulation, giving your skin a vibrant glow as well as clearing your mind, says Renee.

Stay away from too much black around the eyes, says makeup artist Julie Harris. Instead try a color like soft violet on the lids, she recommends.

Julie also likes to use a tinted or sheer moisturizing balm on the lips to give them a fuller, more moisturized look. Dry, caked lipstick in the cracks of your mouth never looks fresh!
