There is one part of that promise that doesn't ring true - this blusher is not at all shimmery. I was worried that the shimmer would make it difficult to wear, but as there isn't any it doesn't. The bronzer palette is slightly less matte, though.
They're certainly not lying when they say the product lasts all day long - I wore it yesterday for a party involving lots of dancing and screaming the words of 90s songs, and it was still there when I got home. I was impressed!
The 'multi-tonal' part is certainly true - one thing I like is that I can lightly swipe a mixture of the bottom two shades around the jaw to serve almost as a bronzer - for a tiny bit of amateur contouring.
