This lightweight and oil-free primer combats shine, absorbs oil and reduces the appearance of pores. Pore Perfecting Face Prmer's purpose is to smooth the skin and blur out the pores to make your face look flawless.  It's also great for oily skins as it helps keep the skin look clear and even. It's clear and adds no pigment. It can be worn alone for a natural look but when worn under makeup it will help keep oil breakthrough from happening even under lights and heat situations.  It is hypoallergenic and formulated with gentle ingredients.  This primer is definitely one of my STAR products and a great trick. ~ Jill xo
