Be wary with oily skin!
So I started using this primer about a month ago and for the first few applications it was perfect over my Bobbi brown foundation, it set my makeup and made it look more polished. However one morning after the spray had dried I noticed these little white dots all over the top of my foundation, obviously caused by the setting spray. I was perplexed as I had loved it just the day before! anyway I had to take my makeup off and start again because nothing would get the little white patches off! I tried it a few more times and the white dots still appeared as soon as my face dried, that is... until one day they just didn't! I realised I hadn't put on my smashbox oil free primer that morning! I've been using the spray successfully now by intentionally leaving out my primer from my routine, I just use this spray as prep now as well as setting spray. As for the actual performance of this product, it immediately melds makeup togeyher and gives a nice polished finish, and keeps me less oily for longer. I still get oily after about 5 hours but that's about three more than when I don't use this setting spray (I have very oily skin). During the first few hours after applying my foundation, it won't budge at all, no transference at all really! However once I start to get oily this effect wears off as would be expected.
