Marc Jacobs Beauty Atomic (400) is a slightly warm-toned, dark copper with a sparkle finish. It is a limited edition lipgloss that retails for $29.00 and contains 0.16 oz.
Marc Jacobs Beauty Atomic (400) Enamored Hi-Shine Lip Lacquer ($28.00 for 0.16 oz.) is a medium-dark, reddish copper with warmer red and gold shimmer/sparkle with lighter, fuchsia shimmer/sparkle as well. The pigmentation was medium in coverage in one layer, and the gloss was thick enough that I wouldn't want to go in with a full second layer. The consistency was lightweight, comfortable to wear, and easy to spread across my lips. I didn't find that this particular shade was as smoothing of my lip lines as others in the formula, but it definitely didn't emphasize my lip lines either. It wore well for four hours and was moisturizing over time.
