NARS Pulsion Lip Gloss ($26.00 for 0.18 oz.) is a soft, rosy plum with warm undertones and a cream finish. It had nearly opaque color payoff in a single layer, which applied without visible streaks but pulled into some of my lip lines. I didn't notice the settling in person as much as I could see it in the close-up photos, though. The gloss had a lightweight, smooth consistency that was thin and had minimal tackiness. It stayed on well for four hours and was lightly moisturizing while worn.
