This is sort of a multi-purpose product. It works great under regular foundation or under pressed powder, and helps control oil all day. You can even wear it alone without any makeup at all. It is completely weightless; you cannot feel it on your face as you put it on. It helps minimize the look of large pores, fills in fine lines a little, and really gives some staying power to your foundation or powder. Also, it actually contains several antioxidants that are good for your skin. This is definitely pricey, but it's effective and lasts a very long time. If you don't want to spend that much, Sephora sells a "to go" version for $15.50.
