Even though this is basically marketed as a moisturizer, I use it a a primer... and I LOVE it. It's lightweight, like a gel, and absorbs into the skin within seconds, but still does what it promises: mattifies and fills in the pores. My problem with most primers that are set to do those tasks is that the consistency and ingredients tend to make me break out. However, I've never had a problem with this and I've already gone through three tubes! If you're oily/combination, especially once the summer months roll by, do yourself a favor and try this out!
