NYX Liquid Suede Sandstorm vs NYX Mechanical Eye Pencil Always Onyx

Both products are intended for use on sensitive facial areas (lips and eyes). Scores favor the Mechanical Eye Pencil for safety (74) versus Liquid Suede (68), but neither dataset includes clinical safety testing details. For the eyeliner, use extra care near the waterline, avoid sharing, and replace if the tip breaks or becomes rough; reviewers also mention breakage and staining of surfaces from broken pieces. For the liquid lipstick, dryness and flaking are common comfort-related concerns—consider lip prep and discontinue use if irritation occurs.

Always follow label directions, keep products capped, and avoid use on broken/irritated skin.

Comfort is a key difference. The Mechanical Eye Pencil scores 88, and reviews consistently describe a soft, smooth glide without tugging. Liquid Suede scores 62; while many find it creamy at first, multiple reviews and the aggregated summary mention dryness or flaking over longer wear. If you dislike the “tight” feel of matte liquid lips, the pencil is likely the more comfortable daily staple.

The Mechanical Eye Pencil is the clear winner for ease of use (93 vs 84). The retractable design removes sharpening and makes touch-ups straightforward. Liquid Suede still scores well—application is generally described as smooth—but liquid matte lips can require more precision around the lip line and some waiting time for the formula to set before you talk, eat, or drink.

Application scores favor the Mechanical Eye Pencil (91) over Liquid Suede (85). Reviews for the pencil repeatedly mention effortless glide and strong pigment in a swipe, which supports quick, controlled placement. The lipstick also applies smoothly and opaquely for many users, but liquid formulas can be more sensitive to layering and can show dryness as they set, which may make the application feel less forgiving if lips aren’t prepped.

Skin compatibility scores favor the Mechanical Eye Pencil (78) over the Liquid Suede lipstick (58). For the lipstick, reviews and the comfort score suggest some users experience dryness or flaking, which can make wear feel less forgiving on already-dry lips. The eyeliner’s creamy texture is often described as smooth and comfortable, though longevity and smudging vary, and some users describe it as “greasy.” As always with products used on sensitive areas (lips/eyes), consider patch testing and stop use if irritation occurs.

Both lines score well for shade range, with the Mechanical Eye Pencil slightly ahead (84 vs 82). Liquid Suede is positioned as available in multiple velvety-soft shades, and reviews mention owning several colours with strong payoff. The Mechanical Eye Pencil is also described as available in natural to bright shades, with reviewers referencing multiple shades. For this comparison specifically, Sandstorm is a nude lip shade, while Always Onyx is a classic black—so the “best” shade choice depends on whether you’re shopping for an everyday nude lip or a staple black liner.

Finish quality is close: Liquid Suede scores 86 and the Mechanical Eye Pencil scores 85. The lipstick is meant to dry down to a striking matte finish, and many reviewers like the matte look, though dryness/flaking can affect how smooth it looks later in the day. The pencil’s “finish” is more about how cleanly the line lays down: reviews frequently note smooth glide and strong pigment, with mixed reports on whether it stays crisp or smudges.

Liquid Suede leads on longevity score (80) compared with the Mechanical Eye Pencil (72). Many lipstick reviewers describe it lasting most of the day, including through drinking, but some mention transfer, smudging, or wear-off when eating. For the eyeliner, some users report all-day wear and minimal smudging, while others say it wears off quickly or smudges easily. If you need the most consistent “set and forget” wear, neither is perfect based on reviews—but the lipstick rates stronger on paper.

Build quality is primarily relevant for the Mechanical Eye Pencil because it’s a mechanical tool format. It scores 62 and has repeated buyer mentions of the pencil breaking easily, which can create mess and wasted product. Liquid Suede doesn’t have a build-quality score in the dataset, but its packaging is a standard liquid lip tube with a doe-foot style application implied by category; the main issues reported are formula-related (dryness/transfer) rather than hardware failure.

Durability scores favor Liquid Suede (74) over the Mechanical Eye Pencil (60). For the pencil, multiple reviews mention breakage, which can shorten the usable life of each unit (even though it’s a 2-pack). For the lipstick, durability concerns are less about the container breaking and more about how the product wears over time (flaking/transfer). If you’re hard on your makeup bag or press firmly when lining, the pencil may require a lighter hand.

Personalization scores are close: Liquid Suede 80 and the Mechanical Eye Pencil 83. The lipstick line appears to offer many shades and is labeled for all skin tones, letting you choose a nude like Sandstorm or bolder colours. The pencil line also spans natural-to-bright shades and suits users who prefer adjustable intensity (light swipe vs built-up liner) and different placements (lash line, smoky blend). For fit, the biggest personal factor is comfort: the pencil is generally easier for sensitive wearers, while the lipstick may suit those who tolerate matte liquid formulas well.

Ingredient quality scores are solid for both, with the Mechanical Eye Pencil ahead (72) vs Liquid Suede (67). Liquid Suede is described as infused with avocado oil and vitamin E, but reviews still commonly flag dryness, suggesting the matte-wear experience may not feel nourishing for everyone. For the pencil, the data focuses more on performance (creamy, pigmented) than on specific ingredients, so the higher score reflects an overall stronger formula impression rather than detailed ingredient transparency.

If you’re ingredient-sensitive, use the full ingredient list from the packaging/retailer to check for personal triggers, since the provided data does not include complete INCI lists.

Packaging quality scores lean toward the Mechanical Eye Pencil (78) vs Liquid Suede (72), mainly due to dispensing convenience. The twist-up mechanism is simple and travel-friendly, but durability concerns show up in reviews (breakage). The Liquid Suede tube format is straightforward and portable, though the product size is small (4 mL) and some users comment on getting limited amount. If you prioritize sturdiness, neither is perfect—handle the pencil gently and keep the lipstick cap tightly closed.

Both products score excellent value, with the Mechanical Eye Pencil slightly ahead (92) vs Liquid Suede (90). The pencil benefits from a very high review count, strong satisfaction, and the 2-pack format at the listed price. Liquid Suede is also widely seen as a strong budget buy due to pigment and finish quality, but the value can drop if you’re sensitive to drying matte formulas or if you need frequent touch-ups due to transfer.

If you want the most “easy wins per dollar,” the pencil edges it; if you want a matte nude lip specifically, the lipstick still offers strong performance for the price.

Both products come from NYX PROFESSIONAL MAKEUP and score similarly for brand trust (Liquid Suede 82; Mechanical Eye Pencil 84). Reviews suggest many buyers consider NYX a reliable affordable brand, and both items have strong star ratings and high review volume. The difference here is minor—your decision will likely be driven more by product format (liquid lip vs retractable pencil) and the specific drawbacks noted in feedback.

Customer satisfaction favors the Mechanical Eye Pencil (91) over Liquid Suede (88), and it also has a much larger review base (102,739 vs 15,539) with a slightly higher average rating (4.5 vs 4.4). For Liquid Suede, repeat praise centers on matte finish, pigment, and value, while repeat complaints focus on dryness and transfer inconsistency. For the pencil, buyers love the glide and pigment, but longevity and smudge resistance vary, and breakage is a notable theme.

Both products score the same for claim support (79 each). In both cases, the general claims (pigment, smooth glide, ease of use) are supported by many reviews. The more absolute performance claims are where feedback becomes mixed: Liquid Suede is positioned as waterproof and long-wearing, yet some reviewers report smudging, transfer, and dryness; the pencil is described as smudge-proof and long-lasting, but some users report wear-off and smudging and also mention breakage. Overall, the “core performance” claims are well aligned, while “all-day/no-smudge” expectations may depend on individual wear conditions.

Both listings emphasize that NYX PROFESSIONAL MAKEUP is acknowledged by PETA as a cruelty-free brand. Scores are strong for both (Liquid Suede 85; Mechanical Eye Pencil 88). Beyond that cruelty-free positioning, the provided data does not include broader sustainability details (such as recyclable packaging), so it’s best to treat ethical comparisons as limited to what’s stated.
