I think I'm in love . . . Just discovered Benefit's the Porefessional. I am a primer connoisseur, seeing as I own 6 high-end primers, and this one (albeit not a primer) is the best. It does what a primer's supposed to do - fill pores and fine lines. Of course, I must mention that your primer's capability seems dependent upon the consistency of your foundation. This one works well with Lancome foundations, or any foundations that are moisturizing!
