Lincoln Park After Dark is OPI's near-black aubergine-purple shade in the brand's standard Nail Lacquer formula (traditional polish, not the GelColor soak-off system). First introduced in 2005 and inspired by Chicago's Lincoln Park neighbourhood, it has remained part of OPI's permanent Classics lineup and is one of the brand's most consistently reordered dark shades.
Like the rest of OPI's Nail Lacquer range, it's a nitrocellulose-based lacquer meant to be used within OPI's three-step system rather than on its own, drying to a glossy, opaque finish in two thin coats.
