Don't overuse this product or you'll end up with a clotted mess
This is an effective primer and a little goes a long way. I have accidentally applied too much and regretted it -- when I tried applying BareMinerals foundation on top, the primer began to rub off and leave rolled up clots on my face. I had to rewash my face and start again. When I used the correct amount, my foundation lasted about 4 hours before starting to shine through. I am currently on the hunt for the best primer and will let you know when I find the one that works for me.
Great application but face still shiny
I had never used a primer and was pleasantly surprised at the difference it makes under makeup. It made the foundation last longer but I didnt help much with shine a couple hours later, my face was just as shiny as it would have been without it.
