WOW! I was starting to think that only MAC paints worked as a base for me, but based on the rave reviews this received I couldn't resist trying it out. If I use a thin layer of Primer Potion my e/s literally lasts all day, with no creasing & minimal fading. I love that I have finally found a truly neutral base, & the wand applicator makes it easy to get a nice thin layer of product without worrying about clumps or smears. A new HG for sure.
