I had this foundation, but found that it did absolutely nothing for my skin, and it was terrible as a foundation too! It was too oily, and looked oily even after applying a generous layer of powder over top. It felt greasy and heavy on my skin and the coverage wasn't good at all, seeing as this is supposed to be formulated for acne prone skin. It smells AWFUL too, overall a terrible product in my eyes.
I've used a ton of different products for my skin, and have tried something from almost every drugstore brand, as well as Retin-A, which irritated my non-sensitive skin so much. I love this system, and even though I still see spots, the life of each spot is a lot shorter than without this cleanser. If you're having trouble with flakiness, I'd highly recommend using the Seven Day Scrub cream once a day or every other day too.
