I too heard that ELF was a dupe so i bought it and let me just say it is no where near the product that MUFE is... I actually gave it to my 5 year old to play with if that gives you any idea of what I thought of it.. I was really disappointed.
I can vouch for CS's silica powder. It's literally the exact same thing (I've tried a sample of MUFE's, it's highway robbery) and you get a carton full of it for I think about $4, and it's perfect for setting makeup. However, I always have to make sure I blend it properly because it can show up in flash photography!
What camera are/were you using, and was the flash turned on? P&S camera flashes are stronger than ones on DSLRs. (It's not always your makeup that causes flashback/white cast.) Anyhoo. MUFE HD is silica powder. And yes, it's too expensive for what it is. It's why I always recommend just buying a full ounce (or more) from Coastal Scents or TKB Trading + a sifter jar, if you want that sort of powder; lots cheaper and you get more for your money. e.l.f.'s adds dimethicone to the silica, to give it more slip (I have this powder and used to use it, and that's what I noticed).I was really disappointed with the HD powder.definitely gives off a white cast. And I blended the crap out of it.
I'll have to give this one a try!I have the oiliest skin on the planet... you can fry something on it...but I've been loving the Korres Mineral powder... does wonders!
Have you tried their super matte powder? It comes is a variety of shades. #18 is my favorite. It's a very light yellow with a bit of a tan tint to it. The super matte shade range is awesome, I love the smooth finish it's setting powder and no flash back. It's very finely milled as well.I was really disappointed with the HD powder.definitely gives off a white cast. And I blended the crap out of it.
