I will start this off by saying I have never been a primer person. Maybe I've been lucky, but I've really never experienced makeup slipping and sliding off my face - unless it was on a blemish, dry spot or my nose. The only reason I tried Glaze it was because it came with the rest of the POV I was ordering, in the Dew It Set. I was unaware of some of the other great benefits you can get from a good primer, until I began to use Glaze It. My makeup glides on so smoothly, and looks more flawless than ever before. Yes, it lasts all day, even in CA heat, but like I said that's never really been a concern of mine. It amazes me that I can layer on a full face of POV, then a full face of makeup on top, and my skin still looks smooth and ..... great. This primer is smoothing and blurring - and I can really see the difference it makes! Once again one of the best parts is that even though it's a "makeup" product - it's infused with skincare. So, while it is helping me look good, I am also putting something on my faces that I can feel good about, knowing that the ingredients are brightening my skin tone and smoothing my skin texture, as well as supporting my skin barrier and hydrating. Glass skin never looked so good!
