I have a real oily T-zone and have tried hundreds of primers over the years. This is a game changer for me. At first I didn't think it would work as it comes out like a clear gel texture. (I've used different brands before that have this texture) this is soo amazing! I could get away 6 hours without having to top up my setting powder (used to do this every hour because I was so oily) I even put this on now when I don't wear make up and I'm so much more confident to be make up free as I'm not shining like an oil slick.
