I bought this due to seeing so many wonderful positive reviews about the product amongst the blogging and youtube community. I decided to bite the bullet last week while browsing through the MAC website and bought it in one of it's lightest shades. MAC says this powder is 'A luxurious domed face powder with minerals, slowly baked to provide a dimensional yet natural/matte coverage. Use to set and fix foundation or as a touch up throughout the day'.
I absolutely agree with what MAC says about this product, it gives you a natural matte finish and it feels quite lightweight on the skin, almost like you don't have any powder on.
You should never be too heavy handed with the powder as it can make your face look extremely cakey. How do I know this? I stupidly made the mistake of building it up, something which I will not be doing again. I ended up going on a shopping trip, looked in a mirror and I had a ghostly/patchy figure staring back at me. It looked so terrible! Never again!
