I bought the full sized bottle after trying MANY primer samples. This one, by far, made my foundation look its best, and last all day. It also smells wonderful and hydrates my skin. Underneath foundation, concealer, setting powder, blush etc. I don\’t see the glow anymore but that\’s okay, it\’s not why I bought it. I do look a bit crazy shiny right after applying it so I wouldn\’t recommend it as a daily moisturizer of you\’re not going to cover it with foundation.
