Which foundation to use?

I'm not going to write a novel... You might want to try the new oil-free liquid mineral foundation from Too Faced, with the primed and poreless finishing powder (also Too Faced) or Smashbox photofinish oil-free liquid foundation and the finishing powder from Tarte. After you're done with the Urban Decay primer, you might want to try some of the Smashbox primer... they have one for oil control. It's definately worth it to use the higher-end products, the nice thing is you can always visit and Ulta or Sephora and have somebody color match you!
