Found this product great for me. I use it as both a primer and as a tinted moisturiser and also as a concealer. Particularly good for disguising those circles under my eyes! The product lasts for ages because you need such a small amount, it really does spread so go easy don't squeeze too much out.
This little product is a definite MUST have in my makeup kit! Sorry Smashbox BB cream you're just not cutting it anymore!
The smell of this i cannot stand but when i only have a couple of minutes to get ready, this does the trick. I used to wear it alone but realised it was a bit too ashen for my yellowy undertones (i wear Medium). I liked the coverage it gave though, it didn't exactly look natural, it was a bit too mattifying for that (once set with loose powder) but it wasn't cakey. I have normal/oily skin and really can't get away with wearing this all day unless i have a oil controlling primer underneath. I've since given it up because it takes almost as long to put on a normal foundation that matches my skin colour.
After reading a couple of other reviews below though i'm going to try just using it under my eyes as a concealer. I'd never thought of that before ^-^
