I just went out yesterday and bought some, (walgreens $4.49) I put it on as a primer this morning, my makeup looks good still, after about 4 hrs. and I'm gonna blot my face at the end of the day to see how it controlled oil, (I'm very oily) but I put in on with a cotton pad and i dont think I put enough on, I was fairly skeptical about it harming my skin, but will be generous tomorrow, and I'll update you on the oil control and makeup staying power.
