Okie so I've got really dry skin and no matter how well I moisturized, my foundation would go on streaky or cakey or bring out any flakiness.
When i first bought this I didn't think it would make much of a difference but I put foundation on one day without it and omg, i could really tell.
It glides on so silkily and smoothly but it doesn't feel heavy at all. You need to let it dry for a minute or so before putting on foundation but I don't mind that.
I use Studio Finish concealer which has a reputation for being really thick and hard to put on but with the primer it went on perfectly.
I've also noticed that I use much less foundation than I used to before the primer and there's less rub-off.
My skin doesn't get very oily (just a small tad on my forehead) so I can't really judge how it does with that but the coverage i now get with my foundation it much more even and smooth.
Since it's so silky, just a pump and a half of the primer is all I need to cover my whole face.
I haven't broken out from it, my sensitive skin hasn't reacted to it at all,and it doesn't feel like I have a film on my face.
The only complaint i have is the packaging. I know that if I were to cut it open once no more product came out, there'd be tons left on the sides of the container just like with Urban Decay Primer Potion.
