This is the best primer that I've ever used! It gives my Combination Dry/Oily T-zone skin the best finish!! It really lasts. If you've used Laura Mercier's and didn't care for it I highly recommend this one. She makes a version for Dry Skin as well, but this one stopped the oil breakthrough for a full 5-6 hours, and the best part-- my foundation doesn't separate. The finish stays true. I pair it with my Aveda compact makeup or my Shiseido liquid and it performs the same. It virtually eliminates the need for powder, a little goes a long way, and it's a great investment!!
