I bought this on a gamble, pores on my nose are huge, no really huge, make doesn't cover them, I saw this and though, well, if it makes any difference, it's worth it. I have been using it twice daily, on freshly washed skin (a tiny amount goes a long way). I only put it on my nose to see if it made any difference. Instantly it mattes the skin, so good for a primer, so I does make the pore look instantly less noticeable. But not shrink them.
So after over a week of consistent use, I can honestly say I've notice that my skin is brighter and pores are much less noticeable, I do recommend this, but change takes time, so wait for the results, my pores haven't disappeared, I'm realistic that will never happen, but this has helped some and that's worth it for me.
