What it is: Rock 'n' Kohl is a no-nonsense, waterproof eye pencil that has the silky-smooth glide of a liquid liner and the soft, pigment-rich result of a kohl.What it does: The easy, one-slick liner melts into your skin, blending then setting to stay in place for up to 14 hours. Crushed pearl powder stimulates collagen production and instantly hydrates, smoothing the surface of the eyelid for an impeccable, highly-pigmented line.How to use: Start from the inner corner of your upper eyelid and as close to the lash line as you can. Draw a thin line across and outward until you get two-thirds toward the outer corner. Extend the line upward and outward to the outer corner to create the illusion of an almond-shaped eye. Work quickly to correct any mistakes as the formula will set after 30 seconds.- Eye Cheat: a nude tone for wider, fuller, more awake eyes.- Bedroom Black: an everyday black.- Barbarella Brown: a dark brown for a softer smoky eye.- Veruscha Mink: a perfect purple slate haze.- Elizabeth Violet: a mesmerizing violet.- Marlene Midnight: a dark blue alternative to black.
