Product Overview

The Too Faced Killer Liner 36-Hour Waterproof Gel Eyeliner Pencil is formulated to deliver ultra-smooth, razor-sharp lines that stay put for up to 36 hours. Housed in a slim pencil design, this liner glides effortlessly along the lash line for precise application, whether you’re creating a classic wing, tightlining the waterline, or crafting a smoky eye. The gel-based formula is non-flaking and transfer-resistant, promising a bold look that won’t smudge, run, or fade over long wear.

The Too Faced Killer Liner comes in an elegant slimline pencil format, weighing in at just 0.04 oz (1.13 g) of product. While this size aligns with typical mid-range gel-pencils on the market, some users have flagged the amount as modest given the recommended 36-hour usage. The product is designed to be sharpened with either the dual-blade sharpener included in Too Faced sets or a high-quality metal pencil sharpener. This sharpening method allows users to maintain a precise tip for clean lines but introduces an ongoing maintenance requirement that some find cumbersome.

The formula itself blends ultra-fine gel pigments with a waterproof resin base. When applied, the liner sets quickly to a transfer-resistant finish that withstands humidity, heat, and even minor eye watering. Practical tests by beauty enthusiasts confirm that the liner can hold up through day-to-night events, including workouts and long office hours. To remove, most consumers rely on an oil-based makeup remover, such as Clinique’s “Take the Day Off,” which effectively dissolves the product with minimal tugging. Overall, the product promises a high-performance, long-lasting result, especially appealing to those seeking a low-maintenance yet durable eyeliner solution.

Packaging-wise, the liner sports Too Faced’s signature black-and-gold aesthetic, with a twist-on cap that clicks into place to seal in moisture. Priced at a premium level relative to drugstore alternatives, the liner retails around $24 per unit. When you calculate cost-per-ounce, it falls in line with mid- to high-end competitors. Many users justify the price by praising the luxurious feel and performance, while budget-conscious shoppers may equilibrate cost against product quantity and potential sharpening waste. Too Faced also releases limited-edition color runs and holiday sets, which may drive occasional sales spikes and gift appeal.

In use, the liner performs best when the product is freshly sharpened. Users report that allowing the pencil to rest upright in a cool, dry place between uses can help maintain its creamy texture, reducing breakage during sharpening. Conversely, exposure to extreme temperatures—such as leaving the pencil in a hot car—can cause the gel core to soften excessively, leading to crumbling or smearing. This sensitivity to environmental factors is common among gel-based liners, and proper storage can mitigate most issues. Overall, as a precision tool in the beauty arsenal, the Too Faced Killer Liner merges high-pigment formulation with a sturdy, travel-friendly design, albeit with a small learning curve around maintenance.

Too Faced Killer Liner Review: Honest Findings

Since its launch, the Too Faced Killer Liner has garnered thousands of reviews on Amazon, culminating in an average rating of approximately 4.3 out of 5 stars. Beauty influencers and everyday consumers alike have tested the liner in diverse scenarios—high heat, humid climates, gym sessions, and all-day work shifts. While the majority of feedback leans heavily positive, a subset of users report specific pain points that impact the overall satisfaction level. By examining the full spectrum of feedback ranging from glowing endorsements to critical observations, one can derive a well-rounded perspective on this much-discussed product.

On the positive side, rich pigmentation and smudge-proof longevity consistently emerge as standout attributes. Nearly all high-star reviews mention that the product “stays on forever,” with some users happily reporting 12 to 16 hours of wear without budging. Those who appreciate bold, defined eyeliner looks—such as precise wings or intense waterline applications—find the gel-pencil formula particularly effective at delivering a crisp line. Even on oily skin types, a light setting of translucent powder over the liner can further extend wear, though many users forgo this step entirely and still report impressive resilience.

Conversely, sharpening challenges and limited product length represent recurring headaches for certain buyers. Unlike twist-up or mechanical liners, the Killer Liner requires manual sharpening to maintain its fine point. This process, while straightforward, can lead to wood waste and product breakage if not handled carefully. A notable share of negative reviews lament the “tiny amount” of usable liner and the absence of an extendable mechanism. Users have experimented with different sharpeners—ranging from standard metal cosmetic sharpeners to German-engineered models—to find the ideal tool, but this trial-and-error can be off-putting for casual makeup wearers.

Another dimension relates to vendor reliability and color accuracy. Multiple customers received shades that did not align with the official listing images—such as receiving a beige “Cashmere” when expecting a true black or a muddy red-brown “Caramel” instead of rich “Espresso.” These inconsistencies often arise when purchasing from third-party vendors rather than official Too Faced storefronts, fueling rumors about counterfeit products and packaging errors. However, no widespread reports of counterfeit toxicity or safety hazards have surfaced, suggesting that the majority of products in circulation are authentic.

Finally, the rumor mill around the Killer Liner has touched on its allegedly minuscule nib size and the idea that Too Faced intentionally supplies less product per pencil. While some reviewers argue that the liner’s survival of the 36-hour wear test necessitates only a small amount per application, others feel shortchanged by the composition-to-price ratio. Despite these murmurs, there is no formal evidence of deceptive sizing or safety issues—only a mix of user expectations and personal preferences shaping the narrative.

Positive Feedback & Highlights

Among positive reviewers, a consistent theme is the liner’s ability to provide flawless precision. Beauty enthusiasts who typically rely on brush-and-gel formats are pleasantly surprised by how the pencil variant glides smoothly without tugging the delicate skin near the eyes. One verified purchaser commented that this is the “only liner” she needs for dramatic winged looks, lauding its “glassy slick gel pencil” feel. Many credit the formula’s creamy consistency for enabling both a sharp line and easy smudged effects when desired.

Another frequently cited highlight is the vibrant pigmentation. Shades like “Midnight” black and “Espresso” brown receive particular acclaim for depth and richness. Users report that the liner “tattoos your eyes with color,” yielding a bold, defined finish that stands out without appearing harsh. Even paler shades—such as “Cashmere”—are noted to deliver on their muted tone while still providing adequate opacity for a nude, understated look.

Moreover, several users highlight the liner’s versatility for waterline application. One reviewer boldly states this is the “only liner I have found that I can use all around the eye and the water line,” praising its ability to stay intact in areas where lesser formulas budge or smear. This feature makes the Killer Liner particularly attractive for looks that require a bold, defined rim from lash to waterline with a single stroke.

Some devoted fans report that a single pencil can last for months under regular use. One makeup aficionado shared that her liner survived six months of daily wear before reaching the warmer, softer core that requires more careful handling. This extended lifespan—combined with the robust color payoff—adds to the sense that the Killer Liner is an economical pick for those who wear eyeliner frequently.

Ease of removal also earns praise—though it requires a makeup remover. A number of reviewers recommend using an oil-based cleanser or clinical makeup remover to break down the formula swiftly with “minimal tug.” Others appreciate that, in a pinch, a high-quality makeup wipe will suffice, albeit with a bit more friction. This dual advantage—durable wear paired with accessible removal—resonates strongly with those who prefer a low-maintenance routine.

The pencil design also enhances portability. Unlike bulkier gel pots or complicated liquid liners that require brushes, the slim form factor fits into standard makeup bags, pockets, and travel kits, protecting against spills and breakage. Many travelers appreciate the convenience of the twist-on cap and the lack of need for extra tools beyond a compact sharpener, making it a go-to for on-the-go touch-ups and vacations.

Despite the higher price point relative to drugstore brands, many users consider the Too Faced Killer Liner a worthy investment. They compare it favorably to more expensive luxury liners—such as Estee Lauder or MAC gel liners—citing equivalent or superior performance at a fraction of the cost. The general consensus among these satisfied customers is that the price-to-performance ratio delivers solid value for those seeking a reliable, long-lasting eyeliner solution.

Negative Reviews & Rumor Analysis

Although many users champion the Killer Liner, a notable cohort reports frustration with certain design and performance elements. Roughly 15% of reviewers assign 1- or 2-star ratings, pinpointing issues ranging from liner smearing to confusion over usability. By analyzing these critiques and separating fact from rumor, we can better understand the limitations and potential caveats of this popular gel-pencil eyeliner.

A dominant complaint centers on sharpening challenges. Unlike mechanical liners, the Killer Liner demands manual sharpening, which some reviewers describe as a “nightmare.” The soft gel core may crumble or break off during sharpening, leading to wasted product and inconsistent tip shape. Several consumers report investing in high-end sharpeners—such as German-made models—in hopes of reducing waste. Yet, even premium sharpeners sometimes shatter the gel, exacerbating user dissatisfaction.

Tied closely to the sharpening issue is the limited product length. Many buyers feel that the liner’s 0.04 oz quantity translates to a very short pencil, especially once you factor in the gradual consumption through sharpening. Some 1-star reviews go as far as calling the product “completely useless” once the initial nib is gone, lamenting the absence of a twist-up mechanism that would extend usable core length.

Color mismatch errors and third-party vendor inconsistencies form another wedge of negative feedback. Multiple customers report ordering a specific shade—such as jet-black “Midnight” or nude “Cashmere”—only to receive a misrepresented color like pale beige or muddy red-brown. These inaccuracies often stem from unauthorized resellers, not Too Faced itself, but they contribute to swirling rumors of counterfeit or repackaged liners in the marketplace.

Confusion also arises from liner packaging design. A number of users mistakenly believed the pencil housed a hidden twist-up mechanism, similar to other retractable liners. The absence of any visible dial led to bewilderment and frustration, with some customers concluding the liner was defective. YouTube tutorials and user guides have since been updated to clarify that the product is indeed manually sharpened, but the initial misunderstanding has fanned rumors that Too Faced deliberately obscures this detail to mask product limitations.

In contrast to the majority who confirm the liner’s waterproof claims, a subset of users finds it surprisingly prone to smearing and flaking. Complaints include black arching under the lower lash line and visible clumping on the waterline after just a few hours. Some low-star reviewers attribute these issues to environmental factors or improper sharpening leaving uneven edges, while others maintain that the formula simply does not live up to its waterproof promise.

Others point out that the waterproof claims make removal overly arduous. Several reviewers describe needing an oil-based remover and multiple cotton pads to clear the liner fully, with residual smudges requiring extra scrubbing. This can potentially lead to ocular irritation or microtears in the skin if performed too vigorously. Although this effect underscores the product’s robust staying power, it also signals a trade-off between lasting wear and user comfort during removal.

Rumors have also circulated online suggesting that Too Faced intentionally supplies a minuscule amount of product to drive repeat purchases. While it’s true that competitors offer twist-up liners with longer barrels and less packaging waste, there is no verified evidence that Too Faced reduces liner quantity beyond standard industry practice. At present, these rumors remain anecdotal, fueled by individual grievances rather than manufacturer admissions or third-party investigations.

No credible reports have emerged tying the Killer Liner to serious safety concerns or adverse eye reactions. A handful of sensitive skin users note mild tugging during removal, but no documented cases of irritation or allergic reactions exceeding typical cosmetic experiences. However, given that some customers struggle with removal and resort to excessive wiping, they may unintentionally stress the delicate eye area, prompting isolated reports of redness or discomfort.

Overall, while the volume of negative feedback is relatively small compared to the glowing endorsements, it highlights critical considerations—particularly around tool compatibility and vendor trustworthiness. Prospective buyers should weigh the high performance potential against the possibility of sharpening frustrations and color inconsistencies, opting to purchase only from reputable sellers and using a compatible sharpener to avoid the most common pitfalls.

Who Should Consider Too Faced Killer Liner?

If you seek an eyeliner that can withstand marathon workdays, travel excursions, or high-intensity workouts, then the Too Faced Killer Liner is a compelling option. Its waterproof formula and bold pigmentation cater specifically to those who refuse to let their makeup falter, making it an excellent choice for event makeup and special-occasion looks.

Makeup artists and beauty influencers who demand razor-sharp definition often turn to gel-based liners for precise application. The Killer Liner’s pencil format allows for direct control and variable line thickness, which suits techniques like tightlining, winged flicks, and graphic eyeliner styles. If you appreciate the tactile feel of a pencil and have experience handling sharpeners, this liner can become a signature tool in your collection.

For those with oily eyelids or who experience midday creasing, this liner stands out as a reliable pick. A light veil of setting powder can further anchor the gel formula, preventing migration into fine lines and under-eye areas. It’s also a solid choice for people who wear contact lenses or have mild eye watering, as the liner’s transfer-resistant finish helps maintain crisp lines without smudging.

Travel enthusiasts also benefit from the pencil form factor. Unlike glass pots prone to spillage or liquid liners that can leak under pressure changes, the slim pencil resists environmental fluctuations when packed properly. Just remember to store it upright and at room temperature to avoid softening in hot conditions.

Even those with sensitive eyes may find the Killer Liner tolerable; a few reviewers with known allergies praised its gentle glide and lack of irritation. Nonetheless, patch testing any new eyeliners is advisable before broad application, especially if you are prone to allergic reactions or eczema around the eye area.

Conversely, casual users or those new to eyeliner may find the maintenance requirements challenging. Manual sharpening introduces variables—such as tip thickness and sharpening waste—that require practice to master. If your daily routine relies on quick, fuss-free application without additional tools, you might prefer twist-up mechanical liners or liquid brushes that need less upkeep.

Budget-conscious shoppers should also consider product longevity versus cost. While many users report a single pencil lasting several months, the initial small quantity and potential for breakage could shorten the lifespan. If you favor a turnkey solution with minimal accessories and clear instructions, alternative formats or drugstore offerings may align better with your preferences.

The liner offers exceptional longevity and color payoff with minor caveats.
Be prepared for sharpening upkeep and ensure authentic purchasing channels.

Conclusion: Final Verdict

After evaluating customer testimonials, performance tests, and rumor debunking, the Too Faced Killer Liner emerges as a strong contender in the long-wear eyeliner category. Its 36-hour waterproof formula really delivers for most users, providing dark, precise lines that resist smudging through heat, humidity, and daily activities. While the manual sharpening method and limited product size introduce a learning curve, these factors do not undermine the liner’s core strengths.

Buyers should exercise caution when ordering from third-party sellers to avoid color mismatches or potential counterfeits. Opt for a quality cosmetic sharpener—preferably metal or German-engineered—to maximize usage and minimize product waste. With these considerations in mind, the Killer Liner represents a valuable addition to any makeup kit, especially when durability and pigment intensity are top priorities.

In conclusion, there are no serious complaints or safety red flags associated with the Too Faced Killer Liner. Rumors about minimal product quantity and hidden twist-up mechanisms are largely unfounded. For those prepared to manage the maintenance aspects, this eyeliner stands up to its marketing claims and surpasses many competitors in the gel-pencil category.

Ultimately, whether you embrace the Killer Liner comes down to your personal makeup habits. If you prize longevity and robust color over instant convenience—or if you’re a beauty pro who enjoys fine-tuning your tools—this pencil liner is well worth the splurge. Otherwise, you may prefer simpler, self-advancing formulas. Either way, the verdict is clear: the Killer Liner lives up to its name for users willing to invest a bit of time in sharpening and color selection.
