I've tried every single primer on the market. I hated Smashbox because the silicone in it "pills"with moisturizer. Fusion was OK, but not great. Then I found this. Containing retin-a and a pore diminishing formula, it leaves my skin looking like velvet. This is the only primer that I'd ever wear ALONE. It makes your skin look absolutely incredible and I get countless compliments on my complexion. I'm never buying another brand. At $38, you get a fairly big tube of it as well, so it's pretty good value.
