Dark Circles

They aren't caused by lack of sleep (even thought no sleep doesnt help any), it's genetic.. so if your parents have them your probably prone to too.  A couple things that will help:

* Take warm tea bags and rest them under your eye.  This should refresh them then apply concealer in little dabs then smear well. Make sure your concealer is the same color of your skin, otherwise it will look fake.

* Whatever you do, do not use a lighter shade of concealer or foundation. This will make it look artificial and will bring it out even more.

CAUTION! the skin under your eye where dark circles appear is only a little thicker than your eyelid so dont use too many produts at once.
