Do you mean this product? http://www.sephora.com/total-matteness-tm-pore-min
It's a mask/cleanser, NOT a primer. It gives you instruction in the how to use section. Basically remove your make up first, then cleanse with it. Or use a cleanser and then use it as a mask. You can use whatever toner/serum/cream that is appropriate for your skin type after that. If you are looking for an oil control primer, try Benefit Porefessional or Hourglass Mineral Veil SPF15 (or search BeautyTalk for past recommendations).
