It looks like the French version of Bare Naturale, which you can get in the US and Canada. It's definitely not all natural, though. It's a step up from traditional liquid and powder makeup, but I really wouldn't consider it mineral makeup because of all the additives. And I don't buy from L'Oreal so I can't tell you how good it is, but I remember a couple people on this forum used it and liked it.
There's some
reviews of it on this site:
