I bought this specifically to use as a setting powder. My dehydrated combination skin has been funky lately, it's dry but still produces oil, not excessively, but enough to break down my foundation if I'm not careful. All my other powders have been too drying. I got this because I wanted to try out the RCMA, and this is basically the exact same thing, but with an annoying fragrance, but waay cheaper. Plus I don't have order it online and then wait for it, I can easily accessible at any convenience store. They even have the same useless cumbersome packaging. I had to purchase a separate powder jar with a sifter and put a bit of it in.
My experience so far, it performs exactly as how people describe what the RCMA does. It doesn't offer much in the way of oil control, it mattifies initially, but if you're oily, after a while the oil will come through. That doesn't really matter because it completely LOCKS the makeup in place, like cement. Even if the oil comes through, it doesn't affect the foundation. The powder keeps my foundations from oxidising throughout the day, doesn't accentuate bad skin texture and prevents foundation breakdown. It works so well as a setting powder that I have noticed that when I blot throughout the day, my foundation hardly transfer, at all. And that's just what I wanted. A not too drying powder that doesn't leave my skin scaly with criss crossed crow's feet marks all over. I still use another oil controling powder on top, but only where I need it. My base stay intact all day, I still blot, but only once or twice, out of habit rather than necessity. I have used this on myself and others on a couple photo ops and it looks fantastic on camera, gives the skin a flawless even look, doesn't flash back. This matters a lot to me because I abhor a white cast, I avoid in my sunscreen, I avoid it in my foundations, the same goes for my powders. It can be used to buffed liberally all over the face (with a soft fluffy brush) and doesn't dry out my skin, even the skin under my eyes, which are the most prone to drying.
I bought the smallest jar, the 50 grams one, for less than a buck. It comes with so much product at such a great price. I don't care if it spills or flies everywhere, if I lost it I'd just go to the corner store and grab another. As for the cancer scare, eh. Talc itself has been proven again and again to not cause cancer, it's the asbestos mixed in in low quality talc, and I hardly think they would allow it in stuff we use to powder our future generation's many a baby's bum. The only risk you get from inhaling this powder is probably choking on its horrendous smell. I don't smell it after I apply it on my face, but that baby powder smell that hits me whenever I open the jar can be a bit much, so I keep it away from my face.
With all that pros and only a few easily countered cons, needless to say I highly recommend it. It's not a magical, all in one powder, but it does have its uses and is a very affordable, dependable workhorse.
