Sadly this is just a bit pathetic - very thin, runny, not much effect when applied. The formula is more like a moisturiser than a primer, as it has none of that 'baby soft' feeling you usually get from the silicones. It didn't reduce the appearance of my pores, didn't create a smooth base for makeup and had no visible effect on prolonging the wear of my foundation. The overall effect was underwhelming. This is not one of MUA's purse friendly miracle products - I'll be sticking with their eyeshadows instead.
