ColourPop The Knockout is a limited edition cheek palette that retails for $16.00 and contains 0.5 oz.
ColourPop The Knockout Pressed Powder Face Duo ($16.00 for 0.52 oz.) features two large face powders--a blush and highlighter--housed in a cardboard palette with an interior mirror. The blush formula is supposed to have "long-wear" with a "soft" and "silky" feel that "can be layered for your desired intensity." The highlighter formula is supposed to have "high-shine" with a "buttery-soft" feel that has "high colour intensity." The two shades coordinated well with each other, and despite the difference in textures, actually layered nicely.
In general, ColourPop's powder blush formula is thinner and can feel a little dusty or powdery, depending on the shade, and has sheerer, more buildable coverage, while the powder highlighter formula is much denser, almost to the point where a dense brush is required to pick up a modicum of product. The upside is the denser quality of the highlighter makes it harder to overdo it from the get-go, so the highlighter has a more buildable glow. I wish their blushes had more of the substance that their matte eyeshadows have, which would give them better adherence and overall coverage.
