My 2 samples came as magazine freebies and they're still going strong. I only use The POREfessional on my cheeks as thats where my pores are more visible so a tube would last me ages but if you plan to use it all over you're face everyday it could get a bit pricey. The texture feels really silky on the skin because of the silicone and helps to make your skin look a lot smoother. I love it so much for the simple fact it helps disguise my pores but in all honesty my make up doesnt last any longer than it would without primer.
Whats your thoughts on primers, do you think they realy help our make up last longer? I'm not convinced.
