In my quest/obsession for perfect airbrushed skin, I was thrilled to try Make Up For Ever's HD Microperfecting Primer. I used the Neutral shade that claimed it "adds natural luminosity to the complexion." I never got far enough to test whether my skin looked "luminous" or not--the primer was hard to blend and left my face sticky, causing the foundation I put over it to look splotchy. I immediately washed it off and started over.
I thought the first application may have been a fluke and I was judging it unfairly, so I tried it again a couple of days later: the same thing happened. Obviously, I am NOT recommending this product, and am sticking with my Smashbox primer.
