this felt greasy and oily throughout the time I wore this foundation (during which I didn't do much, I just was out in the humid weather having dinner), and my skin felt suffocated. I kept going to look at myself in the mirror and touching my face, even though the product looked and felt fine. It was all down to how it FELT.

Needless to say I rushed home and took this off my face immediately, so I can't judge on its 12-hour claim. Maybe in a very very thin layer as a primer, it might do better, but I don't really want to test it out again. It didn't work well with oily skin AND flaky skin, so I don't know who to recommend this to either. You really have to test it out yourself, because judging by many other reviews this product can definitely work well. It is just not for me, unfortunately!
