I have very oily skin and I found that although this did minimize pores and foundation application went on smoothr, my oil broke through much earlier than without primer. I may try this again but use with milk of magnesia I got from dollar store that is the best for controlling oil IMHO.
I have VERY oily skin, it works for a little while, but my shine and oil starts to come through after a little while...it's not AS bad as if I didn't have it on. I think it's worth the price. Goes on very matte and smooth
