Coloring in your waterline isn’t a necessary step when wearing eyeliner, but it can have a major impact. I believe it was comedian Alice Wetterlund who once said (and I paraphrase), if you apply eyeliner along your upper lashline but you don’t line your waterline, it kind of looks like your eye is wearing a belt. That’s not universally true, of course — but it happens to be true for me, so I always give my upper waterline a good layer of black or brown pencil liner to make the base of my lashes look especially dense.
Also called “tightlining,” lining your waterline can make a huge difference on your finished eye-makeup look, especially along the lower waterline. It can add continuity in an intense, smoky eye or an impactful jolt of unexpected color in an otherwise low-key look. But there’s a certain finesse required for applying eyeliner inside your lash line — namely, not flinching when a somewhat pointy object comes closer to your eyeball than it otherwise would.
More importantly, formula and product design matter — especially if you’re trying to pull off a particularly graphic liner look. Water-resistant and waterproof pencils are a must when you’re applying color to a perpetually wet part of your eye area. So whether you’re going for the Margot Tenenbaum aesthetic, the my-lashes-but-better tightline, or the crayoned-on angsty mall-goth vibe, these eyeliners will comfortably cling to your waterline all day.
