Fantastic at controlling oil
I love this primer I have used over ten others, and they did not come through as promised with the mattifying agent. The others would fall short within a few hours (2 hours), and I was frustrated to look in the mirror and see all my hard work from applying my makeup to be greasy and creased. So one day, I stumbled upon this primer, and I decided to try it, and it was worth all the anxiety and money. I will never buy another primer besides this one ever again. I am 100% satisfied, and I can now go over 10 hours with no oil. That's a whole workday!!
