I mean it does what it says. Pores are "erased" but other than that, if I were to rate this as a primer it's average. I haven't really noticed any of my makeup staying on longer than usual, but nor have I noticed it smudging too early. At the very least it minimizes my pores, but at the end of the day I'll probably won't repurchase it because it doesn't affect my foundation. It smells very strongly of baby powder and somewhat like sunscreen?
