I actually didn't even take note of the difference at first, which, looking back, is amazing in itself. It was only later in the afternoon that I noticed that my normally shiny forehead was not shiny at all. The next morning I used The Present again, and after waiting the 2 minutes to let it sink in I looked at my face and, sure enough, the shinyness that had been there, that was normally there, was completely gone. I was left with beautifully matte skin, that lasted all day long. I didn't even need any powder at all, as there was no shine to try to cover up with it.
This is my first foray into the world of makeup primers, and I'm curious as to what other brands are like. But Philosophy definitely has me very impressed so far!
