I love this stuff!!! LOVE IT! Im not too big into primers and i wasn’t using one until i stumbled upon this. It leaves me a little less oily throughout the day, foundation goes on smoother, but mainly I think it leaves a nice healthy barrier between your skin and your makeup. Being really acne prone I try to do as little as a makeup artist in 2015 can when it comes to my skin and i found that my skin actually cleared up a little bit once I started using this.
