Every Type of Eyeliner Explained: Pencil, Gel, Liquid, Felt
The short answer
Pencil eyeliner is easiest for beginners; liquid and felt-tip give the sharpest lines.
The Four Main Types of Eyeliner
The eyeliner market divides into four formula families. Each has a distinct texture, applicator, finish, and appropriate use case. Choosing the right one isn't about which is "best" — it's about what your skill level, look, and eye anatomy require.
1. Pencil Eyeliner
What It Is
The classic: a pigment-loaded wax core in a wood, plastic, or mechanical casing. Pencil eyeliners are the most widely owned and most intuitive format.
Formula
Pencil cores combine waxes (beeswax, carnauba, ozokerite) with pigments (iron oxides, carbon black, ultramarines), oils for slip, and silicones for a smooth glide. The balance between hard waxes and oils determines how soft or firm the pencil feels — a softer formula smudges easily, a harder one draws crisper lines.
Kohl and kajal caution: Some pencils are marketed as kohl or kajal. Traditional kohl formulations may contain lead compounds (galena/lead sulfide). The FDA maintains import alerts for products labeled kohl, kajal, surma, or al-kahl because of potential lead contamination. Look for western-formulated kohl-style pencils that disclose their full ingredient list and contain iron oxide in place of lead.
Finish & Longevity
Depending on wax hardness and added silicones, pencil liner ranges from soft and smudgeable (great for smoky looks) to firm and precise (thin, controlled lines). Most pencil liners wear 4–8 hours; waterproof versions incorporate additional silicone polymers and may wear all day.
Best For
- Beginners learning liner placement
- Smoked-out lower lash lines
- Tightlining (upper waterline) — see notes on ocular safety below
- Everyday looks that need quick, low-stakes application
Tip
Twist-up retractable pencils never need sharpening; traditional wood pencils sharpen to a finer point for more precision. Chill a soft pencil in the refrigerator for 5 minutes before applying if you find it too draggy or shaky-line-inducing.
2. Gel Eyeliner
What It Is
Gel liner is a creamy, intensely pigmented paste — available in two formats: pot gel (applied with an angled brush) and gel pencil or twist-up retractable (a gel formula in an automatic pencil housing). Gel is the professional's workhorse.
Formula
Pot gels are water-in-silicone or silicone-in-water emulsions combined with waxes and high concentrations of pigment. The gel texture gives a smooth, creamy application that sets to a semi-matte or satin finish. Film-forming polymers lock the formula in place once dry, which is why gel liner outlasts most pencil formulas. Gel pencils approximate the same formula in a more convenient delivery.
Finish & Longevity
Rich, dense color payoff. Once set (usually 30–60 seconds), pot gel is highly transfer-resistant and can remain intact 12–16 hours with a primer. Gel pencils are marginally less long-wearing than pot gel but significantly more convenient.
Best For
- Dramatic, graphic, or stage looks requiring all-day wear
- Tightlining (the firmer set of gel means less migration into the eye than liquid)
- Precise wing or liner work (pot gel with an angled brush allows custom shaping)
- Professionals and anyone who needs certified longevity
Tip
Pot gel dries out if left uncapped. Replace every 3–6 months; a dried-out gel causes dragging that disrupts application. Work quickly — apply within 30 seconds of picking up product or it begins to set on the brush.
3. Liquid Eyeliner (Brush Applicator)
What It Is
A water-based or alcohol-based formula with pigment held in suspension, delivered via a fine brush (natural hair or synthetic). The classic liquid liner bottle has a long, thin brush that the user controls by hand. This is the format that delivers the crispest, most graphic lines.
Formula
Liquid liners are aqueous suspensions of pigment (typically carbon black for blacks, iron oxides for colored liners), film-forming polymers (acrylic or polyurethane resins for waterproofing), and humectants to keep the formula fluid. The formula dries quickly on skin, which is both a strength (fast set, sharp lines) and a limitation (no smudging once set).
Finish & Longevity
High-shine or matte depending on resin content. Waterproof versions can resist humidity and tears for 10–16 hours. Non-waterproof formulas smudge more easily but remove with water.
Best For
- Sharp, precise cat-eye wings
- Graphic liner looks (colored lines, floating liner, cut-crease liner)
- Anyone who has mastered eyeliner basics and wants clean precision
Challenges
The free brush requires a steady hand. Beginners often find the variation in pressure changes line weight unpredictably. Use the dot-and-connect technique (place dots along the lash line, then connect them) rather than attempting a single continuous stroke until control develops.
4. Felt-Tip / Marker Liner
What It Is
A liquid-liner formula delivered through a firm felt or fiber-tip nib rather than a free brush. The nib acts like a pen, giving the control of a marker — much more forgiving than a loose brush.
Formula
The formula inside the barrel is identical to standard liquid liner. The difference is entirely in the applicator: the felt nib's firmness prevents overloading and keeps line weight consistent. Fine tips (~0.1 mm) draw hair-like precision lines; chiseled or brush-nib hybrids allow variable line widths.
Finish & Longevity
Comparable to liquid liner — fast-drying, transfer-resistant, available in waterproof formulas.
Best For
- Beginners who want liquid-liner precision without the difficulty of a loose brush
- Everyday wing application at speed
- Offices or anyone applying liner without a stable surface
- Bold, graphic liner work where consistent line weight matters
Tip
Tip shape matters: a pointed nib suits sharp wings; a chisel nib lets you draw both fine and thick lines in one stroke; a brush-nib hybrid blends liquid and gel-liner benefits.

Eyeliner Safety: What to Know
FDA-Approved Color Additives Only
Under US law, color additives used in eye-area cosmetics must be specifically approved by the FDA for that use. Not all pigments approved for skin use are permitted in products applied near the eyes — using a lip liner or general cosmetic liner on the waterline may expose the eye to unapproved additives. The FDA publishes its complete list of approved color additives on its website.
Kohl and Lead Risk
The FDA has issued import alerts for kohl, kajal, surma, al-kahl, tiro, tozali, and kwalli products because many traditional formulations contain lead salts. Lead is not an approved color additive in US cosmetics. If a product's label includes these terms, check the full ingredient list for iron oxides (safe) versus lead compounds (unsafe). Children's exposure to lead-containing kohl has been documented to cause elevated blood lead levels.
Waterline Application and Tear Film
A 2019 study published in Eye and Contact Lens found that eyeliner applied at the inner lash margin (the waterline/tightline position) migrated onto the tear film within 5 minutes in significantly greater quantities than liner applied to the outer periocular skin. A 2022 PMC study confirmed that regular eyeliner use is associated with meibomian gland dysfunction — blockage or structural changes to the glands that produce the lipid layer of the tear film. The mechanism may involve either physical obstruction of gland orifices or low-grade inflammation from formula ingredients. Ophthalmologists generally recommend applying liner along the outer skin surface of the lash line rather than on the inner waterline to minimize tear-film contamination.
Sharing and Shelf Life
Never share eye cosmetics — the eye area harbours Staphylococcus aureus and other bacteria that transfer easily on applicators. Replace pencils and pots every 3–6 months after opening; sharpen pencils regularly to expose a fresh surface. Discard any product that has changed smell, texture, or consistency.
Which Type Should You Start With?
If you are new to eyeliner, start with a soft pencil in your dominant hand. Its forgiveness — smudge it if the line is imperfect, blend it with a brush or fingertip — makes the learning curve gentle. Once you're comfortable with placement, move to a gel pencil for crisper lines and longer wear, then a felt-tip liner for wings. Save a brush-applicator liquid liner until you have the hand steadiness to control it.

Frequently asked questions
What is the longest-lasting type of eyeliner?
Pot gel eyeliner, applied with an angled brush over an eyeshadow primer, consistently delivers the longest wear — commonly 12–16 hours without significant fading or transfer. Liquid liners with waterproof film-forming polymers are close behind. Pencil eyeliner, especially softer formulas, fades and smudges the fastest — typically 4–8 hours without a setting spray or primer.
Is kohl eyeliner safe?
It depends on the specific formulation. Traditional kohl (also sold as kajal, surma, al-kahl) contains lead sulfide or other lead salts — not an approved color additive in US cosmetics, and a documented public health hazard, particularly for children. The FDA has import alerts for these products. Western cosmetics labeled as 'kohl-inspired' or 'kohl-look' typically use iron oxides instead and are safe. Always check the ingredient list rather than relying on the marketing name.
Can I use any eyeliner on the waterline?
Not all formulas are designed for waterline (inner lash margin) use. Liquid liners with free-flowing brushes can run directly into the eye and cause significant irritation — avoid them on the waterline. Pencils and gel pencils are the standard choice for waterline application. Research confirms that any eyeliner applied to the inner waterline migrates onto the tear film more readily than liner placed on the outer lash-line skin, so minimize waterline application if you have dry eyes, contact lenses, or meibomian gland issues.
How often should I replace eyeliner?
Liquid and gel liner (both pot and tube formats) should be replaced every 3–6 months after opening — the aqueous base is hospitable to bacterial growth, and proximity to the eye makes contamination a real risk. Pencil eyeliners last longer (up to 1–2 years) because the product is dry and each sharpening exposes a clean surface, but discard sooner if you notice any off smell, texture change, or unusual eye irritation after use.
What is the difference between a gel liner and a gel pencil?
The formula is substantially the same — both are creamy, pigment-rich gel formulations. The difference is the applicator. Pot gel requires a separate angled brush and allows you to control line weight, shape, and thickness with precision. A gel pencil (or retractable gel liner) is self-contained — convenient, faster, and easier for everyday use, but with slightly less control than a brush-applied pot gel. Makeup artists commonly use pot gel; everyday wearers often prefer the convenience of a gel pencil.
Which eyeliner is best for beginners?
A soft, creamy pencil liner or a felt-tip liner. Pencil liner is forgiving — mistakes smudge away, and the familiar grip of a pencil makes control easier. A felt-tip liner gives liquid-liner precision without the skill requirement of a loose brush. Both are significantly less demanding than a brush-applicator liquid liner, which requires consistent pressure and hand steadiness to produce an even line.
