de-slick in a tube $28.00
My face is oily and I used to have to re-apply my powder several times throughout the day. I have tried several primers, but Urban Decay de-slick is top of the pile for me. I received a sample with another purchase, and I haven't looked back since. I put this on in the morning and my face remains oil free all day and my makeup stays in place. This is a little pricer than I would normally spend on a beauty product, but it is worth every penny. You don't need to use much, so a tube will last a long time.
