What it Is:  A densely-pigmented opaque liner with all-day wear that's gentle enough for tightlining but strong enough to withstand a tough workout or hot, humid weather. Why it's Different: This transfer-proof liner instantly forms a waterproof film that stands up to sweat, humidity, tears and more.  For minimal smudging and intense definition, it's formulated with the lowest possible level of oils and waxesthe result is pure, crisp color payoff that doesn't fade or fall out.  The pigment-rich formula glides on evenly on lids for smooth, uniform application, and the precise swivel-up pencil lets you create a range of liner looks. How to Use It: Apply as close to the lash line as possible. Line the entire length of the lid using short, even strokes. Can be used for tightlining along the waterline.
