Thru Line Waterproof Eyeliner

Yes, Thru Line Waterproof Eyeliner is ophthalmologist-tested and safe for the waterline and sensitive eyes. The pigments are coated in avocado oil, so they glide on smoothly without dragging or tugging the delicate skin along the lash line and waterline. It applies comfortably whether you’re tightlining the upper lash line or lining the inner rim, and it stays put once it sets.

Thru Line is longwear waterproof eyeliner with up to 24-hour wear. Once it sets, the formula is smudge-resistant, transfer-resistant, sweatproof, and humidity-proof. It works well for sensitive eyes, hooded lids, or anyone whose liner tends to fade, smudge, or transfer. Apply and blend any soft or smoked-out looks quickly—after the formula sets, it locks into place for the full wear time.

Yes! Hooded eyes are one of the trickiest shapes for liner because the lid folds down and makes contact throughout the day, which causes most pencils to transfer and smudge. Thru Line is a smudge-resistant, transfer-resistant waterproof eyeliner pencil, so it stays exactly where it is applied. It’s the perfect everyday option for hooded, mature, or deep-set eyes, where long wear matters most.

Thru Line works with most eyeliner application techniques. You can tightline along the upper lash line for subtle definition, line the waterline for depth, draw a thin, precise line for a clean look, or blend it out for a smoky effect. Work quickly on any blended or smudged-out styles—the formula locks in for 24-hour wear once it sets.

Thru Line is formulated with sensitive eyes in mind, not just color. Avocado Oil-Coated Pigments and Omega Fatty Acids give the formula its smooth, tug-free glide for comfortable wear, even on the waterline. It’s also vegan, cruelty-free, and formulated without fragrance, gluten, or talc.

Thru Line comes in 10 shades in matte and shimmer finishes, so you can design everything from a natural daytime look to a lived-in smoky eye. The matte shades are perfect for clean, precise lines and tightlining, while the shimmer shades add subtle dimension along the lash line or inner corner. With shades that ranged from nuanced neutrals to rich jewel tones, there’s a color for most looks, skin tones, and preferences. Every shade is waterproof and safe for sensitive eyes.

Some waterproof eyeliner pencils trade comfort for performance, so they end up dragging, tugging, or irritating sensitive eyes. Thru Line is designed to do both. It combines up to 24-hour wear with an ophthalmologist-tested formula that’s safe for sensitive eyes and the waterline. The pigments are coated in avocado oil for smooth, non-irritating glide, and omega fatty acids help support comfortable wear on even the most delicate skin. The result is a long-wear, smudge-resistant, transfer-resistant liner that feels comfortable to wear.
