Traditional Pencil Eyeliner: The Accessible Foundation
What it is

For many, the traditional pencil eyeliner serves as their initial foray into the realm of eye makeup. Its inherent control, without demanding absolute precision, makes it a perennial favorite, often retained long after initial experimentation. These pencils are typically firmer, offering a forgiving application that allows for gradual intensity rather than an immediate, stark line.
Rose Siard, a respected makeup artist, highlights the versatility of this classic: "A traditional pencil is usually a little firmer and more forgiving, which makes it great for beginners or anyone who wants soft definition without committing to a super-sharp line." Siard’s personal preference leans towards the Make Up For Ever Artist Color Pencil for its rich pigmentation, blendability, and the control it offers without harshness.
Unlike softer formulas like kohl or gel, traditional pencils possess a slight resistance, enabling a more controlled buildup of color. Christian Briceno, a Los Angeles-based makeup artist, elaborates on this advantage: "I like that resistance because it lets me apply the definition gradually rather than deposit a heavy line all at once." This controlled application results in a softer, more diffused finish compared to the high-impact appearance of liquid liners, even with deep, dark shades.
Uses
The traditional pencil eyeliner is a veritable workhorse in any makeup kit. It excels at providing everyday lash line definition, subtly filling in the spaces between lashes, softly elongating the outer corners of the eyes, and serving as the initial layer for a smoky eye look.

Steve Kassajikian, makeup artist and director of global artistry at Urban Decay, notes its blendability: "While it is smudge-capable, you just need to be a bit quicker to do so, as it will dry down to lock into place." This ability to blend before setting makes it ideal for creating softer transitions.
Siard frequently employs these pencils for preliminary sketching of winged liner shapes, offering a less committal starting point. Briceno reaches for them when a subtle, effortless definition is desired, avoiding a heavily drawn-on appearance. He also finds them particularly effective on textured eyelids, where the ability to build and soften the line offers greater flexibility than fast-drying formulas.
Pro Tips
A common pitfall for beginners is attempting to draw a single, unbroken line from the inner to the outer corner. Siard offers a crucial piece of advice: "My biggest tip is to use short strokes instead of trying to draw one perfect line." This technique ensures a more even application and allows for adjustments.
For a natural lash-enhancing effect, Briceno suggests pressing the pencil directly into the lash roots rather than applying it above the lash line. He advises concentrating the deepest pigment at the outer third of the eye and gradually lightening the pressure as one moves inward.

Both artists agree that a pencil that feels too sharp can be softened by swatching it on the back of the hand before application. Briceno endorses the Mineral Fusion Eye Pencil for its balance of smoothness and control, stating, "You still get precision without the pencil scratching or catching."
Kohl and Kajal: The Masters of Smoke and Depth
What it is
Evolving from ancient Egyptian and South Asian traditions, kohl and kajal eyeliners offer a richer, softer pigment compared to their traditional pencil counterparts. They are the go-to choice for achieving a smokier, more dramatic effect. "Kohl is richer, softer, and more generous with pigment," explains Briceno. "It is designed to move, which is why it creates that smoked, slightly lived-in effect so well."
Kohl and kajal pencils, with ‘kajal’ being the Hindustani term for ‘kohl,’ are inherently designed for intentional smudging. Tiesha Williams, a Los Angeles-based makeup artist, emphasizes their utility: "If you want to do a smoky eye, this would be your best bet." Their blendable, creamy texture is what makes them perfect for achieving a blurred, diffused eyeliner look, but it also necessitates a gentler application.
It is important to note that modern cosmetic products marketed as "kohl" or "kajal" in Western markets do not contain actual kohl, which has been banned due to concerns over heavy metal content. Cosmetic chemist Kelly Dobos clarifies, "Actual kohl is banned because of high heavy metal levels, and it’s unsafe in the eye area. But the use as a marketing term ‘kohl’ is okay as long as no actual kohl is used." These formulations are designed to mimic the characteristic smudge and softness of traditional kohl, offering a safe and effective alternative.

Uses
Kohl and kajal pencils are best suited for looks that do not require a sharp, defined edge. They are ideal for creating smudged wings, dramatic smoky eyes, or even applying a wash of color across the lid. When applied between the upper lashes, they can create the illusion of fuller lashes without an obvious line.
Unlike liquid liners that define precise edges, kohl and kajal create a diffused dimension. Briceno finds the Victoria Beckham Beauty Satin Kajal Liner particularly effective for achieving a "sensual rather than precise" eye look, offering ample time for shaping and smoking without feeling greasy or unstable.
Pro Tips
Due to their soft, creamy texture, a gentle touch is paramount when using kohl and kajal. Williams advises, "Be gentle when using kohl because the creamy, buttery texture makes it delicate and easy to break during application." She often favors the Black Radiance Eye Appeal Blending Kohl for its integrated smudger, which simplifies achieving a smoldering effect.

Intensity should be built up gradually, starting from the outer corner where depth is most desired, and blending inward. Applying too much product across the entire eye at once can compromise control. For the waterline, Briceno suggests applying one layer, allowing the eye to blink and transfer pigment naturally, before adding more for a subtle, diffused look.
Gel Pencil Eyeliner: The Versatile Hybrid
What it is
Gel pencil eyeliners represent a significant advancement, bridging the gap between traditional pencils and liquid liners. They offer the user-friendly application of a pencil with the enhanced payoff and longevity typically associated with gel formulas. "A gel pencil gives you the ease of a pencil with more payoff and wear time," says Siard. "It usually glides on creamier, then sets, so you get a little playtime before it locks in."
Steve Kassajikian notes their adaptability: "Gels are more versatile as, unlike liquid, they don’t require as steady a hand and can be blurred and smudged or sharp and graphic." He also points out their generally waterproof nature. While they possess a softness akin to kohl and kajal, gel pencils are formulated to set and hold their shape once blended, offering superior staying power.
Uses

Gel pencils are truly multi-taskers, ideal for any definition that needs to endure. Williams highlights their reliability for demanding applications like bridal makeup or on-screen performances. "These are great for those waterproof-necessary moments," she states.
They are particularly effective for tightlining, defining the waterline, creating long-lasting smoky eyes, and adding intense definition along the lash line. Briceno also champions gel pencils for introducing color, noting that shades like navy, bronze, aubergine, or forest green can be seamlessly integrated into the lash line for a sophisticated, almost neutral effect.
Pro Tips
The key to mastering gel pencils lies in working efficiently due to their setting time. "Work in small sections. Gel pencils can set quickly, so line, blend, then move on," advises Siard. For a softer finish, immediate blending with a small brush before the formula dries is recommended. Siard finds the Urban Decay 24/7 Liquid Stick Retractable Liner particularly user-friendly due to its built-in brush, which aids in application and blending. For sharper wings, a precise liner brush can be used to refine the edges.
For extended wear on the waterline, Briceno suggests blotting away excess moisture with a clean cotton swab before application to ensure even pigment transfer and longevity. He recommends the Lancôme Drama Liqui-Pencil for its strong pigment and suitability for the waterline and outer lashes, providing definition without harshness.

Gel and Cream Pots: The Pinnacle of Precision and Customization
What it is
Gel and cream pot eyeliners are celebrated for their creamy, highly pigmented formulas that glide on smoothly, allowing for precise application with a brush. Brenda Orduno, a makeup artist and senior product developer at Beauty Creations Cosmetics, describes them as delivering "the clean, bold finish of a liquid formula, but because it’s so creamy and you apply it with a brush, you have more control over the shape, thickness, and intensity."
The requirement of a separate brush might seem daunting, but it is precisely this element that grants unparalleled customization. "A gel pot is great when you want control," Siard emphasizes. "You’re applying it with a brush, so you can decide if you want a tight line, a clean wing, or something more dramatic."
Uses
This formula is arguably the most versatile, suitable for classic wings, cat eyes, tightlining, graphic designs, and even smoky eyes. Briceno explains, "With a gel pot, the brush controls the line’s personality. I can use the same product for almost invisible definition between the lashes, a polished wing, or something much more graphic. It has more body than liquid, so it is easier to place and correct, yet it still produces a cleaner, more saturated result than most pencils."

The creamy texture allows for blending before the product sets, making it an excellent choice for those who desire precision but also the flexibility to adjust their look. Orduno points out that the formulation enables the creation of ultra-thin lines at the inner corners, gradual thickening towards the outer edges, or even use as a base for eyeshadow.
Pro Tips
Orduno advocates for applying gel liner in "short, thin strokes for a smoother, more precise line," rather than attempting a single, perfect stroke. Overloading the brush with product should be avoided, as this can lead to dragging, skipping, or an overly thick line. Briceno advises coating both sides of the brush, removing excess, and ensuring the bristles form a clean edge before application.
Proper storage is critical to maintain the formula’s integrity. "Keep the cap closed as much as possible so it doesn’t dry out," urges Siard. She, along with many Allure editors, favors the Jones Road Gel Liner for its quality. Briceno suggests decanting small amounts onto a palette and immediately sealing the jar to preserve the texture. Orduno also stresses the importance of cleaning brushes after each use for hygiene and optimal application.
Felt-Tip Liquid Eyeliner: The Marker for Sharpness
What it is

Felt-tip liquid eyeliners function much like markers, providing a firm applicator that facilitates the creation of clean, precise lines. "It’s great for crisp lines, quick wings, and anyone who likes a more structured look," says Siard, who highly recommends the Stila Stay All Day Waterproof Liquid Eye Liner for its ease in achieving various line thicknesses and wing shapes. Briceno enthusiastically echoes this recommendation.
Compared to liquid liners with brush applicators, felt-tip pens offer a more straightforward and stable application due to the less flexible tip. This firmness is advantageous for achieving sharp lines, particularly for those new to winged liner. However, Briceno notes a potential drawback: "It creates a consistent line very well, but it may not move as gracefully over folds or textured skin as individual brush bristles."
Uses
Felt-tip liquid liners are the ideal choice for classic winged liner, cat eyes, and any look demanding sharp, defined upper lash definition where a polished, intentional appearance is desired. Briceno highlights the precision of the tip for small corrections, such as filling in gaps between lashes or refining the outer edge of a wing. It is also well-suited for meticulously filling in graphic liner designs.
Pro Tips

Patience is key when applying winged liner. Siard advises against stretching the eye excessively during application, as the shape can alter once the lid is relaxed. "Don’t stretch the eye too much because the shape can change once you let go," she cautions. This advice is particularly relevant as skin elasticity naturally decreases over time.
Briceno describes his technique: "I establish the direction of the wing while the eye is open and looking straight ahead, then connect it back to the lashes. The shape should respond to the actual eye, not to an angle imagined while the lid is closed."
He also recommends using the side of the felt tip for the majority of the lash line, reserving the point for fine details and the wing’s tail. This method ensures a smoother, more consistent application. The Lisa Eldridge Kitten Flick Liquid Eyeliner is a favored product for its precision and ability to create fine, sharp lines.
Brush-Tip Liquid Eyeliner: The Artist’s Canvas
What it is
Brush-tip liquid eyeliner offers the most artistic and potentially the most challenging application. Its flexible bristles allow for a wide range of effects, from ultra-fine inner corner lines to dramatic, graphic wings. "A liquid brush liner is more expressive than a felt tip because the bristles respond directly to pressure," Briceno explains.

While this flexibility enables elegant tapering and fine detail, it also means that hand tremors or hesitations are more readily apparent. Unlike the consistent line produced by a felt tip, a brush liner requires a more nuanced control, behaving much like a tiny paintbrush.
Uses
This formula is the preferred choice for looks demanding bold color payoff and intricate precision, according to Orduno. It is ideal for statement wings, emphasized inner corners, and avant-garde graphic designs where the eyeliner is the focal point of the look.
Kassajikian acknowledges its potent pigment but notes it may not be the most forgiving for beginners or for creating smoky effects. "The formula will dry down, so it doesn’t leave much room for mistakes and isn’t suggested for smudging," he advises. Briceno, however, finds the MAC Liquidlast 24-Hour Waterproof Liner excellent for maintaining crispness and longevity, particularly for creating elongated, tapering wings, as the bristles naturally converge to a finer point with reduced pressure.
Pro Tips

Mastering brush-tip liquid liner rewards patience and a relaxed grip. Briceno suggests anchoring the elbow and allowing the brush to guide the application, rather than gripping too tightly, which can amplify hand movements. "Holding the applicator too tightly makes every small movement of the hand more visible," he notes.
He recommends mapping the desired shape with small marks while the eyes are open and relaxed, then connecting them, ensuring the liner follows the natural eye contour. "I would rather build it gradually on a relaxed eye," he states.
Orduno also advises building the line with small strokes and allowing each layer to dry completely before adding more to prevent smudging. Maintaining the cap tightly closed when not in use is crucial to prevent the liquid from drying out. Kassajikian offers a technique for thickening a wing: starting from the outermost point of the pre-drawn line and connecting it back to the mid-eyelid.
