Tightlining Eyeliner How-To: The Makeup Trick That Makes Lashes Longer, Fuller & Thicker (VIDEO)

We've roadtested many a defining mascara, even lash-enhancing serums like Latisse, all in the pursuit of fuller lashes. But there's actually a super simple makeup trick that will make lashes appear longer and thicker.

Tightlining, as we learn in the Bellasugar video above, is an eyeliner trick that makes the lashes appear to start farther back on the eyelid, thus making them look longer.

Instead of lining above the lashes (the way you would apply liquid liner), work the product underneath into the water line. All you need is gel eyeliner and a small angled brush.

Start by pulling up the lid, then pat the liner into the water line ... moving from the outside in. It's not as scary as it sounds, just focus on the area and make sure it's really coated. What's genius is that this trick elongates lashes and defines the eyes without mascara. You can add a coat of your favorite tube, but the effect is still quite strong without it.
