When you stay up all night studying -- or partying with your friends -- you'll often end up with raccoon eyes as proof of your exhaustion. Under-eye circles don't just pop up when you're tired, though. If yours never seem to go away, genetics might be at fault. No matter the cause of your dark circles, you can cover them up with the right concealer. Add a bit of eye liner and shadow, and you'll look like you fueled up with eight hours of sleep even if you're running on fumes.

Step 1

Clean the skin under and around your eyes with a damp washcloth. Pat dry with a towel.

Step 2

Apply a small dab of moisturizer or eye cream below each eye. Massage the cream in gently. This will help the concealer adhere to your skin and keep your skin hydrated.

Step 3

Put a small amount of pink, yellow or peach concealer on a thin brush or the tip of your finger. Use peach concealer if you have gray or green circles. Pink and yellow work better for purple or bluish circles.

Step 4

Pat the concealer only on the dark circles under your eyes. Pay particular attention to the corners of your eyes; circles are usually quite dark there.

Step 5

Apply a concealer that's one or two shades lighter than your skin tone over the pink or peach color. This helps make your under-eye skin look brighter.

Step 6

Dust the skin under your eyes with translucent powder to set the concealer.

Step 7

Apply matte brown shadow to the creases of your eyelids. This gives your eyes a wide-open look and helps minimize shadows.

Step 8

Use a dark brown eye pencil to draw a thin line just above your upper and lower lash lines. Make the line from the inner to the outer corners of your eyes.

Step 9

Use a bright blue pencil to draw another line over the brown. Start about one-third of the way in from the outer corner and extend out. The blue color makes eyes look whiter.

Step 10

Finish the look with two coats of mascara on the upper lashes.
