A lifesaver for reducing blackheads!! As someone who has struggled with blackheads for years, I'm so happy to have found this. It's my savior, as liquid foundation clogged my pores and produced a lot of blackheads. If I apply this and then liquid foundation, I don't get any blackheads at all. They're not zero, but they're far less than before. And if I apply this and then powder foundation, they're even less. But for those who absolutely need the coverage of a liquid foundation, this base-powder strategy isn't for them... I use this method because I think skin without blackheads looks better, even if the skin tone is a little uneven. I hope this helps others who are struggling.
