To cover up those dark eye circles invest in a good concealer that is lightweight and of premium texture. You will want to look for a shade that is peachy or pink in tone. Take some of the concealer and dot it onto the dark line only and then blend it in with your finger. Most people also have a red patch at the outer corner of the eye. Covering this with concealer will give the eyes an immediate lift. Applying some concealer is much better than applying a lot of makeup.
