When I swatched this in store it looked great! Nice thick consistency which can be blended out and has a more powdery finish. But we've all had the experience of stepping into the harsh light of day (or wherever you would normally apply makeup in the morning) and seeing that the colour is actually a bad match for you.
With only a limited shade range, I personally wasn't able to find the right colour for me. In terms of the formula, it performed as an average undereye concealer with strong orange tones to counteract dark circles. The powdery finish was a bit terrible on my blemishes though... I felt it actually brought attention to them!
In the end I gave my concealer to a friend after trying it a few different ways. It seems to work well for her, so was just a bad product for my skin needs.
I like this concealer and use it daily under my eyes to hide the bags. It is easy to apply in the 'lipstick' style tube and i blend it with my fingers. I think it would be nicer to blend in with a concealer brush but i dont have one yet. The colour looks natural and i definately notice a difference when i wear it. I love the packaging and that its very compact too.
