I was very excited to get this deluxe sample because it gets such rave reviews on their site and Sephora (although all their products have no less than 4 stars on their site which I find a little suspect). I got the original, colorless formula but they have many different takes on it - color correcting, luminizing, hydrating, dark spot correcting and with spf. The original goes on smoothly and gives a nice powdery finish that alone makes skin look a little more even and "soft." Not all primers are made for oil control but in my opinion, they should work that way. I also believe that any primer should be able to be used alone for that purpose if you already have good skin that is just sometimes shiny. I didn't use this one alone because I need a little more color. It was easy to apply my Smashbox BB Cream over top. I usually finish with some kind of powder. All of that sounds good but I really wasn't impressed with its staying power. By the middle of the day I would be very oily in my T-zone. The one thing I can say is that, after blotting, it looked nice again and lasted for a few more hours. I don't think any product can be perfect but it was the amount of shine that swayed me. Any good primer should help control it better than this. Unless I just have the oiliest face known to man, I really don't see what all the hype is about.
