This product makes my face even greasier by the end of the day than if I don't wear a primer at all. As an added bonus, as my makeup slides off of my increasingly oily face, the primer seems to cause the makeup to actually settle into my pores (which haven't been filled with primer, obviously) and makes them stand out even more. I can't believe I paid money for this product! I had read such great reviews in several magazines and decided to give it a try. The Clinique in my are will not give this out as a sample, which I found odd because I have never found a product they would not let me sample. Now I know why....it's just awful.
Perhaps it works for people who have large pores from having acne as teenagers, but no longer have oily skin. But as I said, this actually made my face much much oilier. Normally I have to blot around lunchtime and again around 3pm. With this product I found that I could either be extremely shiny or I could blot nearly every hour. At first I thought maybe I was putting on too much or too little primer, so I experimented with varying amounts, and even tried not wearing foundation, just powder over it, and also tried just wearing foundation without powder....with pretty much the same result every day. I tried putting it on and letting it "set" before I put anything over it. I even tried mixing it in with my foundation. I tried applying it with fingers, sponge, and a foundation brush. Nothing makes this product work for me.
On the plus side, this did not cause me to break out at all, which is one bonus that it has over pretty much every other primer I have tried.
