If there’s one eyeliner technique that can instantly elevate almost any makeup look, it’s waterline eyeliner. This pro-approved technique (also known as “tightlining”) does everything from making natural lashes appear thicker and fuller to subtly enhancing eye shape—and it’s essential for a truly seamless smokey eye. That said, waterline eyeliner can be tricky to master, since it involves lining the inner rim of the eyelid, a delicate area that calls for a gentle, careful approach.

Fortunately, you don’t have to figure it all out yourself. Below, we’ll explain exactly how to apply eyeliner to your waterline, whether you’re after a sultry look or simply want to make your everyday makeup pop. Then, we’ll share some of our top tips for preventing smudging and introduce you to a few of our best eyeliners to line your waterline. Keep scrolling for all of the details.

Upper vs. Lower Waterline: What’s The Difference?

Before we dive into how to use eyeliner on your waterline, it’s helpful to distinguish between lining your upper and lower waterlines, because there is a notable difference.

If you want to make your lashes look thicker, typically, you’ll want to line your upper waterline. This thin strip of skin sits between your lashes and your eyeball, and isn’t really visible most of the time. However, tightlining the upper waterline with a dark eyeliner (either black or brown) can help create the illusion of denser lashes, which complements both natural and glam makeup looks beautifully.

Lower waterline eyeliner is a bit more versatile—and noticeable. You can apply eyeliner here to define your eyes, add a subtle pop of color to your look, or even make your eyes look bigger. The key is to use the right technique and choose the right eyeliner (and color) for your needs.

Is It Safe To Apply Eyeliner To Your Waterline?

It can feel intimidating to put eyeliner so close to your eye, especially if your eyes are sensitive, but doing so is generally safe. That being said, it’s important to use the right type of eyeliner to avoid irritation or discomfort (and to replace your products often). Keep reading to learn more about how to keep your eyes safe when applying waterline eyeliner.

Use a waterline-safe formula

It may seem obvious, but the most important factor when choosing an eyeliner for your waterline is whether it’s gentle enough for such a delicate area. While most eyeliners won’t explicitly say they’re waterline-safe, look for callouts like “ophthalmologist-tested” or “non-irritating,” which generally indicate formulas suitable for use along the inner rim of the eye. Waterproof formulas are also a smart choice, since non-waterproof liners are more likely to smudge, fade, or bleed as the day goes on. Our L’Oréal Paris Infallible Grip Mechanical Gel Liner is a good eyeliner for the waterline, as it’s ophthalmologist-tested, smudge-proof, and suitable for sensitive eyes.

Replace eye products often

Using old or expired eye makeup products can increase your risk of irritation, per the American Academy of Dermatology (AAD). To keep your eyes safe, follow these guidelines:

• Sharpenable pencil eyeliners: Replace annually
• Non-sharpenable pencil and gel eyeliners: Replace every three to six months
• Liquid eyeliners: Replace every three to six months

Additionally, throw away any makeup products that develop a smell, change color or texture, or have visible signs of mold (usually white or gray spots). These are all signs that the product has gone bad and should not be used. And if you’re ever unsure whether a product is safe to use, play it safe and toss it—and consider it an opportunity to indulge in a little retail therapy.

What’s The Best Eyeliner For Your Waterline?

Liquid and traditional pencil eyeliners can be great for defining your lash line, but these formulas aren’t ideal for your waterline. Instead, seek out smooth-gliding gel or cream formulas that apply easily and won’t smudge or transfer throughout the day. If you need more help pinpointing the best eyeliner for your waterline, here are a few tips to keep in mind.

Choose creamy formulas

Classic pencil eyeliners can tug at your skin, which may irritate the delicate waterline area. To minimize the risk of pulling, tugging at, or otherwise damaging your delicate waterline, it’s best to seek out formulas with a softer, creamier texture. We love the L’Oréal Paris Infallible Pro-Last Waterproof Up To 24HR Pencil Eyeliner, which boasts a waterproof formula that glides on easily and delivers up to 24 hours of smudge-proof wear.

Try a gel eyeliner

If you’re wary of using a pencil eyeliner on your waterline, consider reaching for a gel eyeliner instead. These hybrid formulas combine the precision of a pencil liner with the comfort and ease of a more fluid formula, allowing for a comfortable application that generally lasts longer than a standard pencil liner. Keep in mind that gel eyeliners come in both mechanical (twist-up) and sharpenable options—if you don’t have an eyeliner pencil sharpener handy, opt for the former, or snag an eyeliner with a built-in sharpener, like the L’Oréal Paris Infallible Never Fail Eyeliner.

Opt for waterproof formulas

To keep your waterline eyeliner looking sharp all day, be sure to use a waterproof formula. Waterproof eyeliner is designed to hold up even if it gets wet, while water-resistant formulas may smudge or bleed if you get caught in the rain or have especially watery eyes. For long-lasting wear that won’t budge no matter what the day throws at you, we recommend the aforementioned L’Oréal Paris Infallible Grip Mechanical Gel Liner, which offers up to 36 hours of smudgeproof, waterproof wear.

How To Tightline Your Upper Waterline

Tightlining (applying eyeliner to your waterline) is a subtle yet powerful way to make your lashes appear thicker and denser. Here’s how to nail the technique in four simple steps.

Step 1: Expose your upper waterline

If you’re wondering how to put eyeliner on your waterline without poking yourself in the eye, we don’t blame you—it can be intimidating if you’ve never done it before. The trick is to expose your waterline before applying your eyeliner so you can get a close look at what you’re doing. Gently lift your upper lid with a clean finger or cotton swab to expose the waterline. This will also help prevent the liner from pulling on the skin and make waterline eyeliner application a lot easier. Alternatively, grab a small hand mirror and look down into it, keeping your head straight. This should allow you to visualize your waterline without having to pull at your eyelid.

Step 2: Prep the area

Before applying waterline eyeliner, use a clean cotton swab or tissue to blot away any excess moisture. A dry surface ensures better product adhesion and reduces the chances of smudging. This step is crucial for ensuring your eyeliner stays put throughout the day.

Step 3: Fill in your waterline

Next, grab your chosen eyeliner (remember: opt for one with a creamy, waterproof formula to ensure a comfortable application and lasting wear). Sharpen the tip, if necessary, then glide the point along the upper waterline. Use short, precise strokes rather than one continuous stroke and maintain even but light pressure on the eyeliner to create a clean, crisp line.

Editor’s tip: You can use any color eyeliner to line your upper waterline, but if your goal is to make your lashes look fuller, opt for a color that closely matches your fringe (or the mascara you plan to use).

Step 4 (optional): Line your upper lash line

For added definition, you can also line your upper lash line, just above where your lashes sit on your lid. Use the same eyeliner or opt for a blendable formula, like the L’Oréal Paris Haute Couleur Kohl Pencil Eyeliner, for a smokey, lived-in feel. Finish with a coat or two of mascara (we love the L’Oréal Paris Paradise Big Deal Buildable Waterproof Mascara) to further enhance your fringe.

How To Apply Eyeliner To Your Lower Waterline

Lower waterline eyeliner can make your eyes appear bigger, enhance your natural eye color, or add a punch of drama to your look, depending on the shade you choose to use. But no matter what you’re going for, the general technique is the same. Here’s how to nail the look.

Step 1: Expose your lower waterline

To access your lower waterline, tilt your chin up slightly and use a clean finger to gently pull down your lower lid. While doing so, keep your eye (and face) relaxed to prevent yourself from tearing up. If you can, try to look slightly upward—this can help keep your eye open, which allows for an easier application.

Step 2: Blot dry

As we mentioned earlier, a dry base is key for long-lasting wear. Use a cotton swab or clean tissue to remove any excess moisture and prepare your waterline for a seamless, even eyeliner application.

Step 3: Fill in your waterline

Next, glide the point of your waterproof liner along the lower waterline, using even, light pressure to create a clean and precise line. If your eyes are sensitive, avoid the inner corner—applying liner here could make your eyes water, which can interfere with your work. Instead, stick close to the lash line and end the line just before your tear duct.

Step 4 (optional): Set with eyeshadow

To enhance the staying power of your waterline eyeliner, lightly dust eyeshadow along your waterline, using a shade that closely matches your liner. This can help “set” your eyeliner (similar to the way setting powder sets foundation) and provide additional defense against smudging and transferring.

Common Waterline Eyeliner Mistakes

The waterline, as we’ve established, is a delicate area—and getting your technique right is the key to minimizing irritation and uneven wear. Here are a few common waterline eyeliner mistakes to avoid when applying your makeup.

• Over-application: Applying too much eyeliner to the waterline can make eyes look smaller or cause the product to transfer and smudge throughout the day. A light hand is key—the goal is to define the eyes without overwhelming them.
• Using the wrong formula: Not all eyeliners are designed for the waterline, and using one that’s too dry, crumbly, or not eye-safe can lead to discomfort or patchy wear. Look for smooth, creamy liners labeled “ophthalmologist-tested” or “safe for sensitive eyes” to ensure a comfortable application and wear.
• Skipping proper prep: Applying eyeliner to a watery or overly moist waterline can cause the product to skip, smear, or wear off quickly. Before lining, gently blot the waterline with a clean cotton swab or tissue to ensure the area is dry, which helps eyeliner apply more smoothly and evenly.
• Aggressively tugging the eyelid: Pulling too hard on the eyelid to expose the waterline can cause irritation and uneven application. Instead, gently tilt your chin up and lightly press the liner into the waterline for more controlled, comfortable results.
• Using too much pressure: Pressing too hard when applying eyeliner to the waterline can irritate the delicate skin and make application uncomfortable. A light, controlled touch allows the liner to glide on more evenly while reducing the risk of redness or discomfort.

Makeup Tips to Keep Waterline Eyeliner From Smearing or Fading

To ensure your waterline eyeliner stays put, a few simple tricks can make a big difference. From prepping your skin to choosing the right formula, these pro tips will help your eyeliner stay crisp, clean, and exactly where you want it all day long.

Prime your lash line

Before applying eyeliner, prep your lash line (not waterline—lash line) with a small amount of eye primer, avoiding the area directly around your tear duct. Eye primer helps create a smooth, oil-free surface that allows your liner to grip better and last longer. Just make sure to let it fully dry before applying your waterline eyeliner for maximum staying power.

Sharpen your pencil before each use

If you’re using a traditional pencil eyeliner to fill in your waterline, sharpen it before applying your liner. This has dual benefits. Sharpening the tip helps remove any debris, oil, or bacteria that may have accumulated on the pencil since your last use, so it’s less likely to irritate your eye area. A freshly sharpened tip also helps you create precise lines, minimizing the risk of uneven color payoff or a messy application.

Avoid touching your eyes

It sounds simple, but it really helps. Try not to rub or touch your eyes during the day. Rubbing can smudge your liner, and even touching your eyes—say, to adjust your contact lenses—can cause your eyes to water, which may make your liner smear or bleed. If your eyes get watery during the day, lightly dab away moisture with a clean tissue instead of rubbing your eyes.

Apply in layers

Instead of doing one heavy swipe of eyeliner, try building up the color in two or three thin layers, waiting a minute or two for the liner to dry between each layer. This method gives the formula time to set between passes and makes it more resistant to smudging.

What Color Eyeliner Works Best For Your Eye Color?

Waterline eyeliner can do more than define your eyes—certain shades can brighten your eyes or make your eye color pop. If you’re looking to enhance your natural features, here’s a quick breakdown of the best eyeliner shades to complement different eye colors.

Blue eyes

Copper, bronze, and navy eyeliners are especially flattering for blue eyes because they create contrast that enhances their natural color. Warm metallics like copper and bronze bring out the richness of blue eyes, while navy adds depth and complements your eyes’ natural cool tone.

Brown eyes

Rich jewel tones like plum, emerald, and deep blue bring out the golden flecks in brown eyes. These colors create a flattering contrast, enhancing your eyes’ depth and vibrancy.

Green eyes

Sultry burgundy and violet tones complement green eyes beautifully. These shades enhance the natural cool and golden tones in the iris, making your eyes pop. See for yourself by swapping your go-to liner look for a subtle pop of burgundy along the upper and lower waterlines.

Hazel eyes

Earthy tones like gold and olive highlight the chameleon-like quality of hazel eyes. They complement the shifting hues in your irises without overwhelming, making your eyes stand out in any lighting.

Editor’s tip: To really play up your eyes, consider swiping on a shadow in a shade similar to your eyeliner. Check out the L’Oréal Paris Paradise Le Shadow Stick lineup, which includes 14 shades to complement a range of eye colors (and makeup preferences).

How To Remove Waterline Eyeliner

Gentle removal is essential for maintaining eye health, especially when removing waterline eyeliner. Start by soaking a cotton pad with micellar water or a gentle, oil-based remover, then press it lightly against your closed eye for a few seconds to help break down the liner. Avoid rubbing or tugging, particularly along the inner rim of the eye, where the skin is most delicate. For precision near the tear duct or along the lash line, use a cotton swab to lift away any remaining product. Finish by rinsing with cool water or following up with a gentle cleanser to leave your eyes clean, calm, and comfortable.
