I used to use the Benefit Pore-fessional primer because my pores are an issue for me. The guy at Sephora told me that it was a horrible choice because it\’s silicone and allows your makeup to slide all over your face. Then he showed this one to me and said it\’s clay based so it covers up your pores, color corrects , AND helps your makeup stick to your skin. And, on top of all that, it\’s nourishing your skin under your makeup all day. I was skeptical at first but now I love it. It\’s fantastic.
