Melt Cosmetics Ultraviolet Blushlight (Trio) ($22.00 for 0.28 oz.) is a jumbo-sized blush compact that contains a pan that's been split into three distinctive shades. The brand says that it can be used "on face and around eyes as desired" (I wonder if "around" is code for "not for the immediate eye area," though). As a blush formula, the heavy, denser, and thicker consistency made it difficult to pick up product, left them often looking thick and textured on my cheeks, and ranged from "make it stop" to "don't apply in a rush" levels of difficulty.
They were pigmented, but they were extremely difficult to apply and blend out on my cheeks, which made me think that they'd be more workable as eyeshadows. The sparkling purple was a total failure across the board, while I had better success with the other two shades, but I'd never want to use these again--far too much effort and not enough reward.
Each shade is physically large enough for a small blush brush or a tapered highlighter to fit easily into them, so the shades were usable as individual hues.
