I had to mention at some point the new Gripping Primer by CoverFX. And yes, it’s sold out everywhere for a reason. If you are expecting a long day ahead, most of mine are, and are relying on some consistency and prolong the wear of your make up, you get this primer. I find that it works best under my Beautyblender foundation not necessarily best under La Prairie or Sisley. It has a light sticky, jelly consistency that apparently grips to your foundation to smooth it over. Yes, it works!
