Well, today i tested my sample of Mineralize Moisture Foundation in NC20. This MAC shade is a little darker and warmer than my skin.
Let me say first that SPF 15 is not really much, so if you want it to protect your face from UVA and UVB rays you might consider using a sunscreen first. I use a daily moisturizer with mineral sunscreen that has SPF 25 - and i would prefer SPF 30.
COLOR
It looked ok when i first put it on. I can't recall how long i wore it, but checking in a mirror again some hours later, it has definitely oxidized. It's not freakishly clown orange, but it's at least one shade darker, if not two, than it was at first. Since i only put it on certain areas of my face, it's not a good look.
FEEL
I can feel it on my face. I don't mind because it feels like a moisturizer, which i wear every day. In fact, i kinda like how it feels. It's there, but it doesn't feel suffocating to me, as some other foundations have felt (especially matte finish). If you have combo or oily skin, you probably won't like the feel. And if you don't like feeling your foundation, you probably won't like this, either.
FINISH
It definitely has the "dewy glow" of moisturizing cream. I don't think it looks greasy or oily, but some of you might. So if you don't like that light-reflecting quality, you will probably not like this foundation
COVERAGE
The coverage was lighter than i expected. It was sort of medium-sheer. And it didn't build up well, because it is so moisturizing. Still, a little goes a fairly long way - i had a generous sample in one of those teeny tiny little jars and all i did was dab my fingers into the foundation on the inside of the lid.
CONCLUSION
I will try again with NC15, which is usually a little lighter than my skin, and see if it acts the same, or if it oxidizes just enough to be wearable.
