This may possibly be my new favorite primer. I am a primer junkie. They make all the difference in the world when it comes to makeup, and being very oily, I cannot live without them. I’ve raved before about the Hourglass Oil-Free Mineral Veil Primer and the Benefit Cosmetics Porefessional Primer. But today, I want to rave about the YSL Beauty Touche Éclat Blur Primer.
