What Judy did was right and I had the same issues. I mixed it with my oil of olay moisturizer and it started to break up even when I set it with a powder foundation on top an hour later. I tried it with my Estee Lauder double wear and it too started to break down and separate which never happens with the ELDW alone. I tried it with a primer and it looked like it just sat on top of my skin, then you guess it, started to separate and break down. I returned it a few days later.
