What brand of concealer is best to cover up dark circles?

I love this concealer from Physicans Formula called Concealer 101 Creamy Duo. It has a yellow side to hide dark circles or redness under the eye. It also has a flesh tone to disguise the yellow. Its creamy, stays on all day and is available at Wal-Mart or any drug store! Great buy for under 8 dollars! Hope I helped!
