I was very eager to try this, as I love my Studio Finish concealer but find it a little too heavy for use under my eyes. It comes in a squeeze tube, and has a light liquid formula. A small amount of this goes a long way, one dab under each eye is enough to cover any dark circles I have; it goes on very smoothly, blends well and the coverage is great. It's not 100% crease resistant, but it holds up a lot better than any other concealer I've used recently, especially when set with powder. I prefer a thicker formula for covering spots or blemishes, so I'll keep my Studio Finish for that purpose, but nothing beats this stuff for covering shadows or circles. The price and color selection are amazing too, it's definitely worth trying!
