NARS Instant Crash is a very warm-toned, light-medium peach with a pearl finish. It is a limited edition lipgloss that retails for $26.00 and contains 0.18 oz.
NARS Instant Crash Lipgloss ($26.00 for 0.18 fl. oz.) is described as a "soft shimmering apricot." It's a light-medium peach with hints of warm, brown and fine white shimmer. It had semi-sheer to semi-opaque pigmentation with a light-to-medium-weight consistency that was mildly sticky but not thick or gluey. It didn't appear streaky, but the color emphasized and sat in lip lines heavily, so it was less flattering worn alone. This shade wore for four hours on me.
