A pencil eyeliner should be easy to control, stay where you put it, and avoid turning your morning routine into a sharpening project. The Maybelline Unstoppable Mechanical Eyeliner Pencil targets those needs with a waterproof, smudge-resistant formula, a twist-up mechanical design, and claimed wear of up to 24 hours. The Onyx version reviewed here is a 0.01 oz black pencil that works especially well for simple lash-line definition. Its main tradeoff is that buyers who want a large shade range, an ultra-fine liquid-style wing, or a specifically waterline-focused pencil have better alternatives.
Quick Verdict
Rating: 8/10, Recommended with caveats
Best For: Everyday users who want an affordable mechanical pencil with waterproof, smudge-resistant wear and no separate sharpener.
Bottom Line: Maybelline Unstoppable combines easy pencil control with up to 24-hour wear and a retractable mechanical format. It is less compelling if you want dozens of colors, a very fine liquid-style line, or a pencil specifically marketed for waterline use.

What Is the Maybelline Unstoppable Eyeliner?
Maybelline Unstoppable is a retractable mechanical eyeliner pencil designed to give you pencil-style control without requiring a separate sharpener. You can twist the product up for application and back down after use. Maybelline describes the formula as waterproof and smudge-resistant, with color designed to stay true for up to 24 hours.
The reviewed Amazon variant is 10 Onyx, a black shade in a 0.01 oz pencil. Maybelline currently lists five shades across the Unstoppable range: Onyx, Cinnabar, Pewter, Sapphire, and Espresso. That is enough choice for basic black, brown, gray, blue, and warmer-toned looks, although shoppers who enjoy a broad range of bright or metallic colors may find the selection limited.

Who Should Buy It?
Best For
- You want a simple pencil eyeliner for daily lash-line definition.
- You prefer a retractable format that does not require a separate sharpener.
- You want waterproof, smudge-resistant wear in a familiar drugstore-priced product.
Skip If
- You want a very thin liquid-style wing or graphic liner effect.
- You need a much larger selection of bright, metallic, or unusual shades.
- You specifically want a liner whose official directions recommend waterline application.
Mechanical Design and Application Control
The mechanical format is one of Unstoppable’s strongest practical features. Instead of sharpening away product or carrying a cosmetic sharpener, you twist the pencil up when you need more liner. Maybelline says the pencil swivels up and down so the point remains ready for application.
A pencil also gives you more physical feedback than many liquid applicators. That can make it easier to keep the tip close to your lashes, build the line gradually, or soften small mistakes before the formula fully settles.
The tradeoff is precision. A mechanical pencil tip will generally create a thicker and softer-looking line than a very fine felt-tip or brush-tip liquid liner. If your main goal is an extremely thin flick, a liquid format may suit you better.
Waterproof and Smudge-Resistant Wear
Maybelline markets Unstoppable as both waterproof and smudge-resistant, with wear of up to 24 hours. That makes it more appropriate for long workdays, events, humid conditions, and other situations where an ordinary soft pencil might transfer or fade sooner.
The 24-hour figure should be treated as a maximum brand wear claim, not a guarantee that every person will get identical results. Eyelid oil, skincare products, eye rubbing, humidity, and how much liner you apply can all affect how makeup behaves during the day.
If your lids become oily, applying liner to clean, dry skin and avoiding rich cream directly along the lash line can give the formula a better surface to grip.
Shade Range and Everyday Versatility
Maybelline currently lists five Unstoppable shades: Onyx, Cinnabar, Pewter, Sapphire, and Espresso. Onyx gives you the classic black definition reviewed here, while Espresso offers a softer brown option. Pewter and Sapphire give you alternatives when you want something less traditional.
The range covers common everyday looks but is modest compared with eyeliner collections that offer dozens of colors and multiple finishes. If color experimentation is your priority, that limited range is one of the clearest reasons to compare alternatives.
How to Apply Maybelline Unstoppable Eyeliner
Start with clean, dry eyelids. Twist up only enough product to expose a usable point, then begin near the inner corner of your upper eyelid and move along the lash line toward the outer corner. Maybelline’s directions specifically recommend drawing along the upper lash line.
For better control, use several short strokes instead of trying to create the entire line in one movement. You can keep pressure light for subtle definition or build the line gradually for a stronger look.
- Make sure your eyelid and lash line are dry.
- Twist up a small amount of eyeliner.
- Place the tip close to the roots of your lashes.
- Draw in short strokes from the inner area toward the outer corner.
- Build a second pass only where you want more depth.
- Twist the pencil down after application before replacing the cap.
Pro Tip: Expose only a short section of the mechanical tip while applying. You get better control and put less sideways pressure on the pencil than you would with a long section twisted out.
Eye Safety, Sensitive Eyes, and Ingredients
Maybelline states that Unstoppable is ophthalmologist tested and suitable for sensitive eyes and contact-lens wearers. That is useful if you normally pay close attention to eye-area compatibility, but it does not mean every individual will tolerate every cosmetic ingredient.
The current ingredient list published by Maybelline includes ingredients such as isododecane, beeswax, carnauba wax, dimethicone-related ingredients, trimethylsiloxysilicate, tocopherol, silica, aloe extract, and pigments that can vary by shade. Cosmetic formulas can change, so check your package if you have a known ingredient sensitivity.
Do not continue using an eye cosmetic if it causes irritation. Avoid applying eye makeup to an injured, infected, or severely irritated eye, and follow the instructions printed on the package.
Maybelline’s official instructions describe applying Unstoppable along the lash line. They do not specifically instruct you to place this product on the inner waterline, so this review does not recommend assuming that use is intended.
How It Performs in Real Use
For Everyday Makeup
The retractable pencil design fits simple daily routines well. You do not need a brush, pot, or sharpener, and you can build the line in small strokes. Onyx gives you clear black definition without requiring liquid-liner technique.
For Long Workdays or Events
The waterproof and smudge-resistant formula is the main reason to choose Unstoppable over a basic soft cosmetic pencil. Maybelline claims up to 24 hours of wear, although your actual result can vary with skin oils, humidity, and rubbing.
For Beginners
A mechanical pencil can be easier to control than a fluid brush-tip formula because the solid tip lets you work slowly. Short strokes also make it easier to correct the shape before adding more product.
For Travel
The twist-up design means you do not need to pack a sharpener. Keep the cap secure and twist the tip back down after use so the exposed product is protected inside the barrel.
Pros and Cons
Pros
- Waterproof and smudge-resistant formula.
- Maybelline claims up to 24 hours of wear.
- Mechanical twist-up design requires no separate sharpener.
- Officially described as suitable for sensitive eyes and contact-lens wearers.
- Five wearable shades cover several everyday eyeliner looks.
Cons
- Five shades are limiting if you want a broad color collection.
- The pencil format is not as fine as a precision liquid-liner tip.
- Official application directions do not specifically recommend inner-waterline use.
What Buyer Feedback Suggests
Buyer feedback for Unstoppable commonly centers on its smooth application, convenient pencil format, and staying power. At the same time, makeup performance is personal, and some users report more smudging than others. That difference is believable because eyelid oil, skincare, eye shape, humidity, and rubbing can all affect transfer.
The useful takeaway is to buy it for its combination of mechanical convenience and long-wear formula, rather than assuming the same wear time will occur on every skin type.
Is It Worth the Price?
Maybelline Unstoppable sits in the drugstore eyeliner category and offers strong value for the price when your priorities are convenience, waterproof wear, and straightforward lash-line application. The mechanical barrel also saves you from needing a separate sharpener.
You get the most value if black, brown, gray, blue, or a warm-toned shade covers your needs. It is less attractive for buyers who want a huge color range, multiple finishes, or a very fine graphic-liner tip.
How It Compares to Alternatives
If maximum pencil wear and a broader color selection matter more than mechanical convenience, Maybelline Tattoo Studio Sharpenable Longwear Waterproof Gel Eyeliner Pencil is worth comparing. Maybelline markets that formula for up to 36 hours of wear and offers substantially more shades, but it uses a sharpenable pencil format.
NYX Epic Wear Waterproof Eyeliner Stick is another option if color choice is your priority, with a much larger selection of matte and metallic-style colors and a longer claimed wear time. If your main goal is a crisp wing rather than a pencil look, a waterproof felt-tip liquid product such as NYX Epic Ink gives you a more precision-focused applicator. Unstoppable makes the most sense when you want a straightforward mechanical pencil with familiar everyday shades and no sharpening step.
Frequently Asked Questions
Is Maybelline Unstoppable Eyeliner suitable for sensitive eyes?
Maybelline states that Unstoppable is ophthalmologist tested and suitable for sensitive eyes. Individual reactions can still differ, so stop using the product if you develop irritation and check the ingredient list if you have known sensitivities.
Can you wear it with contact lenses?
Yes. Maybelline specifically identifies the eyeliner as suitable for contact-lens wearers. Apply it carefully around the eye and follow normal contact-lens hygiene practices.
Can Maybelline Unstoppable be used on the waterline?
Maybelline’s published Unstoppable directions describe application along the lash line and do not specifically instruct users to apply it to the inner waterline. Follow the packaging directions rather than assuming the product is intended for that use.
Does Maybelline Unstoppable really last 24 hours?
Maybelline advertises the eyeliner for up to 24-hour wear. That is a maximum wear claim, and your actual result can depend on eyelid oil, humidity, skincare products, rubbing, and application technique.
Does the eyeliner need to be sharpened?
No separate sharpener is required. Unstoppable uses a mechanical design that swivels the pencil up and down, which is one of its main convenience advantages over traditional wood pencils.
How do you remove Maybelline Unstoppable Eyeliner?
Maybelline recommends removing the eyeliner with an appropriate eye-makeup remover. Because the formula is waterproof and designed for long wear, use gentle makeup-removal products instead of rubbing the eye area aggressively.
Is Maybelline cruelty-free?
Maybelline currently states that it does not test on animals and uses non-animal methods to evaluate cosmetic safety. Its parent company’s published policy also says an exception could be made if regulatory authorities demanded animal testing for safety or regulatory purposes, so buyers following a strict certification standard should check the latest policy before purchasing.
The Bottom Line
The Maybelline Unstoppable Mechanical Eyeliner Pencil is a solid choice if you want easy pencil control, waterproof and smudge-resistant wear, and a twist-up design that does not need a separate sharpener. Choose it for straightforward everyday definition, but consider another eyeliner if your priorities are a very broad shade range, an ultra-fine liquid-style wing, or specifically documented waterline application.
