I had a couple of really blissful months with this powder, it really did blur the pores and helped keep my makeup intact. It took the oils away without my skin looking powdery at all, it just disappeared into my skin! I used it under my eyes too. However, the powder ended up drying out my skin after several months of daily use. My face would feel tight at the end of the day and my pores were getting bigger (skin was producing more oil to compensate for the dryness). I have combination skin so this one might be best for oily skin types. I've stopped using it and my skin is much better now - sad! Really wanted this to work forever.
One thing application wise that did bother me is how fine the powder is and how it goes everywhere, I always seem to breathe it in and I know I have because the powder has a distinct smell.
