Applying eyeliner to the lower lash line or waterline is a completely different skill from a classic winged lid. The slightest smudge, transfer, or flake turns a sharp look into tired, raccoon eyes within hours — especially on contact lens wearers or those with naturally watery eyes. The under-eye zone is moist, mobile, and sensitive, demanding a formula that locks in place without irritation.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve analyzed hundreds of cosmetic formulas for their film-forming polymers, pigment load, and ophthalmologist-grade safety data to separate the few liners that truly survive the lower lash line from the many that claim to.
This guide breaks down the waterproof, smudge-proof, and ophthalmologist-tested formulations that actually perform under the eyes, helping you find the best eyeliner for under eyes that won’t migrate or irritate.
How To Choose The Best Eyeliner For Under Eyes
The under-eye area is unique — it’s constantly blinking, tearing, and creasing. You need a formula engineered for this specific zone, not a general eyeliner adapted for it. The three factors below separate a liner that fades from one that stays.
Waterline Safety & Ophthalmologist Testing
A simple “waterproof” claim means nothing on the wet mucosal tissue of the waterline. Look for explicit ophthalmologist-tested and contact-lens-safe labels. These products undergo irritation and corneal staining tests. bareMinerals Mineralist, for example, is dermatologist- and ophthalmologist-tested and explicitly marked safe for the waterline. Skipping this certification risks stinging, redness, and chronic sensitivity.
Formula Type: Pencil vs. Gel vs. Liquid Pen
For the lower lash line, pencil and gel formulas provide the best control with minimal transfer. Liquid pens, like the Kokie Precise Longwear, work well for tightlining the upper lid but can feel wet and take longer to set on the lower waterline. Mechanical gel pencils (NYX Epic Inky Stix) offer the ideal middle ground — creamy enough to glide without tugging, yet quick-drying to lock into place before the blink cycle disrupts them.
Film-Forming Polymers & Wear Time
The key to 12-plus hour smudge resistance under the eyes is a film-forming polymer network. These polymers (often acrylates or silicone-based resins) create a flexible, water-resistant film around the pigment as the solvent evaporates. The Pixi Beauty Endless Silky Eye Pen and the tarte double take both use this technology to survive sweat, tears, and extended wear. Products without this film stage tend to turn greasy and slide into fine lines within a few hours.

In‑Depth Reviews
1. bareMinerals Mineralist Lasting Eyeliner
This formula is mineral-based, vegan, and enriched with avocado oil and aloe vera — ingredients that soothe rather than strip the sensitive under-eye tissue. The retractable pencil glides on without tugging, delivers a rich pigment in one stroke, and remains creamy for a few seconds to allow blending before setting to a transfer-proof finish. It is dermatologist-tested, ophthalmologist-tested, and explicitly labeled safe for the waterline and contact lens wearers, which immediately separates it from 90 percent of the category.
On the lower lash line, the pigment stays locked in place for a full 12-hour wear cycle — no flaking into fine lines and no mid-day smudge migration toward the outer corner. The buildable intensity means one pass gives a soft definition while two layers create a bolder, more dramatic line. The set time is about 15 seconds, so you have a small blending window for a smoked-out effect before the film fully locks.
The only gripe from long-term users is that the tip does not stay sharply pointed, making it slightly less ideal for micro-fine, hair-thin lines along the lower lashes. If you prefer a precise, razor-thin stroke, apply with the side edge of the pencil rather than the full tip. For contact lens wearers and anyone prone to eye sting, this is the safest and most reliable daily driver.
Why it’s great
- Ophthalmologist-tested and safe for waterline and contact lenses
- Mineral-based formula with nourishing avocado oil and aloe
- Transfer-proof and smudge-proof for all-day lower lash wear
Good to know
- Tip rounds with use, not ideal for ultra-thin hairline strokes
- Line appears thicker than preferred on lower lash line
2. tarte double take eyeliner
The tarte double take is a 2-in-1 system: one end houses a semi-matte gel pencil for the waterline and lower lashes, and the other a precision felt-tip liquid for defined flicks. The gel pencil side uses a film-forming polymer blend that survives 12-plus hours in brutal conditions — verified by users wearing it through freezing rain, wind, and watery eyes in New York City without any smudge or fade. The color payoff is a true matte black that stays opaque without turning gray as the day goes on.
For under-eye application, the gel pencil is the star. It goes on smoothly with no tugging and dries to a smudge-proof, transfer-proof finish within seconds. The pencil tip maintains its shape well, allowing for a controlled line along the lower lash margin. The liquid side is best reserved for winged looks on the upper lid — multiple users report that the liquid irritates their waterline and occasionally leaks a taste into the mouth, so stick to the pencil for the lower zone.
The compact tube design is travel-friendly, and both sides deliver strong color for the price. The only compromise is that the liquid end cannot be used comfortably on the waterline for sensitive eyes, making this more of a one-trick pony for under-eye work if you rely heavily on the liquid side. But for those who want a solid daily pencil that outlasts most competitors on the lower lash line, the gel side alone justifies the buy.
Why it’s great
- Gel pencil side delivers all-day smudge-proof wear on lower lash line
- Vegan and cruelty-free with strong matte black pigment
- Survives tears, wind, and extended wear without transfer
Good to know
- Liquid side can irritate waterline for sensitive eyes
- Liquid end not recommended for the under-eye area
3. NYX Professional Makeup Epic Inky Stix
The Epic Inky Stix uses a mechanical cream gel formulation that delivers one-swipe fluid color with no dragging or skipping across the lower lash line. The slanted precision tip is the key differentiator here — the angled edge allows you to create both a thick, smudged base along the waterline and a fine line along the lash root by simply rotating the pencil. This makes it one of the most versatile tools for under-eye work without needing a separate brush.
The quick-dry technology sets the pigment into a waterproof, smudge-resistant film within seconds. Multiple user reviews confirm it survives a full day in humid southern climates without dropping onto the under-eye area. The pigment load is dense — one swipe delivers an opaque line that does not require layering. The click mechanism at the base advances the gel without sharpening, eliminating the waste and mess of wooden pencils.
Some users note that the click mechanism is a bit slow and the amount of product dispensed per click can be slightly unpredictable, requiring a short learning curve. The tip is also relatively thin, which is great for precision but means you may need to go over a section twice if you want a bolder lower-lash line. For anyone seeking a tight, crisp lower-lash definition without the tug of a traditional pencil, this is a strong mid-range performer.
Why it’s great
- Slanted angled tip for precise thick or thin lower lash lines
- Quick-dry waterproof formula with no skip or drag
- Mechanical twist-up design, no sharpening needed
Good to know
- Click mechanism can be slow and inconsistent with output
- Fine tip requires multiple passes for a bold line
4. Pixi Beauty Endless Silky Eye Pen
The Pixi Endless Silky Eye Pen has developed a cult following among waterline users for a simple reason — it genuinely stays on that moist mucosal tissue for 12 hours without fading or transferring. The waterproof formula is built around a film-forming polymer that locks pigment to the waterline without requiring a primer. Users with hooded eyes specifically report zero smudging into the crease, which is a testament to the formula’s quick-drying and transfer-resistant properties.
The application is exceptionally smooth — the pencil glides without any tugging, even on the delicate waterline tissue. The color intensity is rich from the first pass, eliminating the need to go over the same spot multiple times (which can cause irritation). It is also hypoallergenic and lightweight, so it does not feel heavy or sticky on the sensitive under-eye zone. Another bonus: the formula works as an eyeshadow base or lip liner, offering multi-use value.
One consistent complaint across reviews is the sharpening experience. The wood casing around the soft core makes sharpening messy, and users report breaking the tip if they twist too aggressively in a standard sharpener. A simple workaround is to chill the pencil for 10 minutes before sharpening to harden the core. Also, you must keep the cap tightly sealed — the formula dries out quickly if left exposed, causing the pencil to harden and become unusable.
Why it’s great
- Proven 12-hour wear on the waterline without smudging
- Hypoallergenic and lightweight, ideal for sensitive eyes
- Multi-use as eyeliner, eyeshadow base, or lip liner
Good to know
- Difficult to sharpen without breaking the soft core
- Dries out quickly if cap is left off
5. Kokie Precise Longwear Liquid Eyeliner
The Kokie Precise Longwear is a liquid pen with a marker-style felt tip, designed for ultra-black, opaque lines that stay put. Unlike many liquid liners that flake or fade within hours, this one uses a shaker ball inside the tube to keep the pigment uniformly suspended, preventing the formula from separating or drying out prematurely. Users with the oiliest eyelids report it survives a full day without running, including through sweat and tears.
For the under-eye area, this works best for a defined lower lash line rather than the waterline itself — the liquid formula can feel wet on the waterline and may take longer to set, increasing the risk of transfer during blinking. The marker tip allows for incredible precision, making it easy to draw a hair-thin line right along the lash root. The ultra-black pigment is noticeably darker than most standard pencil liners, giving a bolder contrast that photographs well.
The main limitation is the drying speed. The formula is not a quick-dry — users note it takes about 30 seconds to fully set, during which any eye movement can cause smudging. Additionally, removal requires a heavy-duty waterproof makeup remover or micellar water with prolonged soaking. If you prefer a liquid finish for your lower lashes and have the patience to let it set, this pen delivers exceptional color and longevity for the price.
Why it’s great
- Ultra-black pigment with true opaque coverage
- Innovative shaker ball prevents formula separation
- Survives sweat and tears on oily eyelids
Good to know
- Not quick-dry — need ~30 seconds to set to avoid smudging
- Requires heavy scrubbing or oil-based remover for full removal
