This BB cream provides light to medium coverage, but it produces a smooth photo finish. If you're used to heavy canvas coverage, you can top the BB cream with a light foundation powder. I often do this if I want a real photo finished look, but for an everyday work look, the BB cream alone as my foundation works just fine. Because it doesn't give a heavy coverage, I still advise using your concealer if you need to brighten up or cover up anything on your face. Smashbox's description states that it also conceals, but I think that depends on how much you, as the user, need to conceal. For example, I have dark circles under my eyes, and the BB cream, while provides some coverage, doesn't quite conceal the dark circles as an actual heavy grade concealer would.
The Smashbox BB cream costs $39 for a 1oz. tube. It is a little steep for the amount that you get, but if you think about some of the products you can remove from your daily facial/makeup routine, I think it's worth the money. I like the Smashbox's version because they do offer several shades.
