Bare Escentuals PRIME TIME
Price: $8 for a travel size at Sephora more for a larger size
I'm not really sure how much I believe in facial primers but this stuff definitely starts out great. It leaves my skin feeling and looking smooth and matt right after I apply it and gives my foundation a good base to cling to. However, it's mattifying effect doesn't last forever. I will often use this before I put on my bare escentuals foundation but by 3 hours in to school my face will start looking oily again.
But if you don't have oily skin this stuff might just work for you! Definitely try it out, it comes in a travel size as well to giver-a-test!
