What it is: A truly original, award-winning, long-wearing eyeliner that offers the precision of a liquid liner with the ease of a gel-based formula, all with 12 hours of waterproof and sweat- and humidity-resistant wear. Why it's different: Highly pigmented, this gel formula delivers subtle to dramatic looks that are easy to apply. It's long-wearing and won't smudge or fade. How to use: Dip the tip of your ultrafine eyeliner brush (sold separately) into Long-Wear Gel Eyeliner, being sure to coat both sides of the brush. Wipe off any excess on a tissue. Working quickly, apply liner in short, even strokes close to the lashline, from the inner to the outer eye corner. Style Name: Bobbi Brown Long-Wear Gel Eyeliner. Style Number: 12023U.
