I hate concealing my dark circles too! I have asian eyes, so I have lots of fine lines underneath my eyes. My circles are fairly dark so I have to apply a fair amount to hide it, but then it cakes up and accentuate those fine lines, even after I set it. Still on my hunt for the perfect concealer. Currently using Benefit Powderflage to set, and I like that a lot, so I think it's just the concealer that I have to work on.
