1 Estee Lauder Double Wear Zero-smudge Liquid Eyeliner, $36
USING IT: The brush was comfortable but liquid-eyeliner newbies will find the quick-drying runny texture a challenge. I had to layer it to make it more intense, and the second layer seemed to remove the original line, leaving flaky specks behind. STAY-ON POWER: Once you master it, you’ll like how it forms a crust-like texture that doesn’t budge. However, the colour smudged a little and transferred ever-so-slightly to eyelid creases. It had great staying power but took the longest time to remove.
