Mineral Veil is supposed to finish off your makeup, or, if you have oily skin, you can brush it on before your powder foundation. I love it to soften my whole look or cover up "mistakes" or places I may have missed with my BE foundation. It is colorless, and blends in with any color foundation. Leaves your face with a "veil" of softness.�I use it especially in the summertime and my face it dry. My girlfriend is very oily and uses it underneath all year 'round. I love it!
