Here is the sheen I am talking about. I have layered this on more than I probably would to go out in public, but for photographic purposes it really shows how gorgeous the colour is. A perfect peachy pink, with just a dash of bronze which would look stunning if I was a little more tanned! This is a versatile product, MSF's aren't specifically for blusher purposes, there are mineralised blushes also available, but an MSF can be used all over the face in some way. It's easy to achieve a light application with MSF's so if you like to wear blusher as well as bronzer, this would be perfect to dust over your bronzer, just to give you that extra bit of glow.
I know this is now a hard to come by product, but it is the stand out product (by a mile!) of this collection and worth trying to hunt down.
I hope that your shopping experience is more successful than mine...when I bought it, I asked for "a Stereo Rose MSF please", expecting the guy that worked there to know what I was talking about. I felt so geeky afterwards, because apparently he didn't know that MSF was shorthand for mineralise skin finish. I thought "Stereo Rose" would give it away, lol I just expected him to know instantly what I was talking about, because jeez, doesn't everyone know what Stereo Rose is! I guess even the people that work in MAC aren't as obsessed as us beauty junkies!
