Works well, so long as you don't have dry skin!

I was recommended this a few years ago to keep my oily skin at bay, and I have to say, as far as mattifying fluids go, it works pretty well for the first little while. It feels very suede-like on the skin, and does reduce oil and shininess, though I didn't find it lasted for too long throughout the day. Mind you, I used it in the early fall, when it was still warm, so it is entirely possible that it would work better during the cooler months. I haven't used many mattifying fluids that do what they say they do, but this one comes really close. Wish I could repurchase but it isn't cruelty-free...
