Minus the fact that it does the change the tone of my foundation because i'm deep dark skin (which is why i returned it), I do like this product, it just does what it says to be short. I'm using it with a kabuki brush which makes it very easy to apply.
the only thing is the packaging is a very big mess, so I've found a solution haha, i bought a kind of compact powder box thingy from the face shop and then put the mac powder inside (i have posted the photos).

remember to do not put too much if you don't wanna look like a ghost, loll.

Seriously my favorite product in my make-up bag. The moment the MAC associate brushed this on half of my face, I could instantly see the difference and was ready to pay whatever they had for it. Such a beautiful finishing powder! It gets rid of any shine on my face and makes everything look perfect. The price was $30 but it was worth every penny. TOTALLY out of my budget but I had to have it.

Mac claims, on their website, that this product "A silky finishing powder that provides an invisible way to set makeup. Reduces shine while optically minimizing the look of pores, lines, imperfections" I don't find it does any of this. It temporarily gets rid of shine but not by much; a plain tissue does a better job then this powder. If you aren't careful it makes white patches of powder on the face. It's also not flash friendly. For the price, I'd expect better results. I wouldn't recommend this to anyone!
