This product is an excellent primer that is definitely a dupe for Benefit's Porefessional. Some Korean bloggers even did a comparison of the two and found that this one covered more pores and fine lines. I personally can't tell a difference. But the fact that it does just as well as Benefit's Porefessional for a fraction of the price is good enough for me. It doesn't control sebum, though--then again, it wasn't advertised to do so.
