Favorite foundation primer. I have oily/combination skin with large pores on my cheeks near my nose and on my chin. This works so well to “fill in” those large pores and make them virtually disappear. Makes my skin really matte, but not too matte to wear it looks fake and unnatural. The primer blends in effortlessly. I like to pat it on the places I need the most coverage - which is namely my cheeks and chin. I put it on after my moisturizer and before applying any face makeup. It lasts a long time without touch ups. It’s very silky, not greasy and feels very lightweight. I buy backups of my backups because I refuse to ever be out of this product. It’s the holy grail of primers for me.
