Didn't do anything for me. I tested the lightest and medium shades and it was either too dark or too light. I still purchased the medium shade though to give it a try, but it ended up making my dark circles worse. I think the formula was too pink and didn't neutralize the purple very well.
However, a little bit of the product goes a long way, so this tiny jar will last a long long time.

This concealer is great, but kind of pricey... It camouflages very well but I find that it leaves skin a little sticky and greasy...
