What it is: An opaque, densely pigmented 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 levels of oils and waxes for pure, crisp color payoff that doesn't fade or fall out. The pigment-rich formula glides on lids evenly for smooth, uniform application, and the precise, swivel-up pencil lets you create a range of liner looks. How to use: Apply as close to the lashline as possible and line the entire length of the lid using short, even strokes. It can also be used for tightlining along the waterline. Style Name: Bobbi Brown Long-Wear Waterproof Eyeliner. Style Number: 5365475 1. Available in stores.
