What it is: An award-winning, long-wearing, waterproof eyeliner featuring the precision of a liquid eyeliner and the ease of a gel-based formula. What it does: The gel eyeliner offers eight hours of waterproof wear that makes it resistant to sweat and humidity. The highly pigmented gel eyeliner formula delivers subtle, dramatic looks that are easy to apply and won't smudge or fade. How to use: Dip the tip of an eyeliner brush (sold separately) into the eyeliner, being sure to coat both sides of the brush. Wipe off any excess with a tissue. Working quickly, apply the liner in short, even strokes, working close to the lashline and moving from the inner to the outer corner of the eye. Ophthalmologist-Tested Imported
