I`ve just got mine from ebay order and tried it twice already: once with the foundation and once without it. In the first case, I think it looked a bit cakey. On my opinion, it doesn`t suit for setting a foundation--too heavy for me. But overally, I found it quite good--it doesn`t tight my skin(my skin is a bit dehydrated now) and the latter does look as if glowing under it.
I have a question, though, for those who has already had some experience with this powder--do you really see any skin improvements a fter using this for some period? In terms of hydration, smoothing little imperfections and etc?
