I received a free sample of the bareMinerals Prime Time original Foundation primer from Ulta Beauty. It's an amazing preservative-free foundation primer that's great for all skin types. This mineral-infused, satin-finish formula glides on seamlessly with no tacky feel to provide a skin-smoothing complexion before I apply foundation. It is great for erasing pores and small dry patches. It also keeps me nicely matte throughout the day on both my dry and oilier areas. The first three ingredients are Cyclopentasiloxane, Dimethicone Crosspolymer, and Dimethicone, which are all silicone-based polymers. a little goes a very long way. It blurs and creates a beautiful, thin layer between your skin and foundation. A little goes a very long way. It blurs and creates a beautiful, thin layer between your skin and foundation. I would purchase a full size.
