Roseshock is a light-medium, pinky lavender with silver and violet sparkle. I didn't notice much of a shift to this shade swatched on my arm or on my cheeks, though it was certainly shiny, sparkling, and noticeable. It had opaque pigmentation that applied fairly well to the skin, though it had a tendency to sheer out a bit as the larger sparkles seemed to move the powder around a bit. The highlighter wore well for eight hours but had some "fallout" as the sparkles migrated while worn.
Metal Crush Extreme Highlighter features liquid-powder technology, so it applies smooth and creamy. It blends out seamlessly to reveal hyper-reflective micro-crystals that shimmer and shift with every movement.
