This is Dior's new long lasting setting (or finishing) powder. My Dior SA recommended it specifically to go with my current fav foundation, Dior Forever. Someone said this powder is only for younger skin, but surprisingly, it works very well on my 59 year old face, too. A very light dusting of Extreme Fix enhances the airbrushed look I love from Forever foundation, it doesn't cake or flake and indeed "sets" a flawless finish that lasts all day. This powder looks white in the container (there is only one universal shade for all skin tones) but goes on completely translucent. You get a lot of product for the money so it will last a very long time, but I would rebuy!
