This NYX primer & serum is a fantastic product that hydrates my skin in addition to giving me a smooth surface on which to apply makeup. I love how simple it was to use, and the convenient pump-style packaging made it easy to control the amount of substance that came out. When I used it, my makeup remained fresh all day. A little goes a long way to be effective. My skin didn’t appear shiny or feel oily because the serum absorbs into my skin rather than merely remaining on the surface. I love this and heartily endorse it!
