This is the only one of the Instain blushes I've been a bit disappointed with. It is described as mauve, so I was hoping for something along the lines of NARS Sin, or even something more purple, but it's quite pink. It's slightly frosty, but blended out that's not too problematic, though, I imagine, if you wanted to build this up it could end up being Frostfest 2013 (which may or may not be what you want).
I've also found that the staining pigment in this one is easier to 'activate' with not fully dry liquid foundation (or moisturiser or any other liquidy stuff on your face) which makes it harder to blend out and brings out a brighter pinky hue which further negates the mauve it's meant to be. It's not a bad blush by any means, it does show up but it's more subtle, so it isn't probably going to be the star of any makeup look. I don't regret buying it, and I'm wearing it now to be a subtle counterpoint to a bright eye look, but it's not as 'wow' as the other shades I've tried. I'm glad I got Pinstripe at the same time, because that really won me over to theBalm's blush line, and this probably wouldn't have.
