I have the Prep+Prime SPF 50. While I wouldn't really say it minimizes pores, it does a good job of lightly 'veiling' the skin with a creamy white MU base (a TINY bit thicker than the reg. Prep+Prime, but it absorbs into the skin just as well--looks more like a white lotion, but goes on like the reg. stuff). Does NOT feel heavy, in fact very similar feel as the reg. Prep+Prime. Holds MU on very well, and where I am it is VERY sunny and my skin felt well protected. I thought that the tube was small at first, but like the salesgirl said, you don't need a lot. Just a couple of drops should be adequate. Put on my Studio Fix Fluid foundation over this and it was great--no meltdowns during the day! Hope this helps some of you out who are on the fence about this product. If you love the regular Prep+Prime, this is even better IMHO. Plus, the tube is very chic! HTH!!
