NYX Fill & Fluff vs NYX Lip IV

Both products have solid safety scores (Fill & Fluff 81; Lip IV 79), with no specific safety incidents provided in the data. Practical safety considerations differ by area: for Fill & Fluff, keep use to the brow area and be careful around the eyes; smudging could be inconvenient if it migrates. For Lip IV, use as directed on lips and stop use if it causes discomfort; it’s also worth noting that a scent/taste is mentioned by reviewers, which some sensitive users may prefer to avoid. Patch testing can be a sensible step for anyone prone to irritation.

Comfort favors NYX Lip IV (88) over NYX Fill & Fluff (84), mainly because lip comfort is central to Lip IV’s user feedback. Reviews often describe Lip IV as silky, smooth, and hydrating, with less stickiness after it settles. Fill & Fluff is also described as smooth and easy to glide on, but comfort issues are more tied to wear behavior (smudging/fading) and occasional brush-end problems than to the feel during application.

NYX Fill & Fluff rates slightly easier to use (89 vs 86). The pencil format plus paddle brush makes it straightforward to fill, shape, and then blend without needing separate tools, and buyers repeatedly call it easy and natural-looking. NYX Lip IV is also simple—apply with the wand for shine, blot for more stain effect—but shade unpredictability can add friction if you’re trying to get a very specific lip color outcome on the first try.

Application quality is strong for both, with NYX Lip IV slightly ahead (89 vs 86). Lip IV reviews often highlight a smooth, even layer and a well-shaped applicator that helps define edges. Fill & Fluff gets consistent praise for gliding on and adding fullness; however, some users mention the pencil can become blunt after a few uses, which may reduce precision and change the application experience over time.

Shade options and matching favor NYX Fill & Fluff (shade range score 87) over NYX Lip IV (74). For brows, buyers often mention that the color looks natural and matches well, which is important for keeping brows believable. For Lip IV, multiple reviews note that shades can appear different than expected versus online swatches and photos, sometimes pulling more red/pink/brown than anticipated. If you want the highest chance of a predictable match on the first try, Fill & Fluff looks safer based on the data.

Finish quality is a clear win for NYX Lip IV (90 vs 83). Lip IV is designed specifically for an “instant wet shine” look, and reviews frequently call out high shine and a smooth finish that can be worn glossy or blotted down. Fill & Fluff’s finish is more about brow realism—soft definition rather than shine—and it scores well, but it’s not meant to create a dramatic finish effect in the same way a lip gloss-stain does.

Longevity strongly favors NYX Lip IV (82) over NYX Fill & Fluff (67). Lip IV reviews often mention lasting for hours and leaving a tint that fades evenly, though eating can reduce wear. Fill & Fluff has more mixed wear feedback: some customers say it stays all day, but others report it doesn’t last long, smudges easily, and isn’t water/sweat resistant. If your routine demands minimal touch-ups, Lip IV is the more dependable option based on the scores.

Scent is mainly a factor for NYX Lip IV (scent score 74). Reviews mention a faint coconut-like smell/taste that many find subtle and not lingering. NYX Fill & Fluff has a low scent score (50), but the provided reviews don’t focus on fragrance; the bigger day-to-day issues are wear and occasional brush-end durability. If you prefer minimal scent in lip products, Lip IV’s coconut note is worth considering.

Build quality is scored the same for both (68), but the real-world implications differ. For NYX Fill & Fluff, build issues show up as the brush attachment coming loose for some users. For NYX Lip IV, the build is mostly about the wand and closure; the reviews provided are more positive on the applicator than negative. If you’re hard on products or toss makeup into a bag, Lip IV’s higher durability score suggests fewer practical problems.

Durability favors NYX Lip IV (80 vs 66). Fill & Fluff’s lower score lines up with reports of the brush end falling off and wear-related issues like smudging, which can reduce how reliably it performs over time. Lip IV appears more stable day-to-day in the provided data, with fewer complaints about the package holding up and more emphasis on consistent wear and comfort. For a product you want to keep in a purse or travel kit, Lip IV looks like the safer bet.

Personalization is fairly close (Fill & Fluff 83; Lip IV 80), but the type of personalization differs. Fill & Fluff benefits from stronger shade range scoring, which helps users match brow tone more precisely. Lip IV offers multiple saturated shades and can be worn in different ways (full gloss vs blotted stain), which adds flexibility in finish and intensity. If you want the most reliable match, Fill & Fluff leads; if you want multiple looks from one lip product, Lip IV is more versatile in wear style.

Ingredient quality is a tie on score (72 for both), and the provided data is stronger for Lip IV than for Fill & Fluff. Lip IV’s listing mentions a vegan formula and highlights ingredients like Magnesium, Vitamin B12, antioxidants, and coconut water, but the full INCI list isn’t provided here, so it’s hard to assess formula sensitivity risks in detail. Fill & Fluff is described mainly by texture and function (smooth, waxy pomade) without a detailed ingredient list in the provided information. If ingredients are a deciding factor, you’d need the full ingredient lists for a more meaningful comparison.

Packaging quality favors NYX Lip IV (78 vs 73). Lip IV’s tube/bottle format and wand are frequently mentioned positively, especially the applicator shape and how much product it holds. Fill & Fluff’s packaging is functional, but there are repeated mentions that the brush end can fall off, which affects daily usability and can be frustrating for travel or handbags.

Value is close, with NYX Fill & Fluff slightly ahead on score (86 vs 85). Fill & Fluff is repeatedly described as good value, and its very high customer satisfaction suggests many buyers feel it performs well for the price—especially for easy, natural-looking brows. Lip IV is also viewed as a strong buy because it can function as both a gloss and a stain-like tint, potentially reducing the need for multiple products. The trade-off is practical: Fill & Fluff may need more touch-ups due to lower longevity, while Lip IV may require more careful shade selection due to swatch mismatch complaints.

Brand trust is strong for both NYX products, with a small edge to NYX Fill & Fluff (84 vs 81). Both listings include cruelty-free positioning acknowledged by PETA, and both products have large review counts that suggest wide usage. The difference here is minor; in practice, shoppers are more likely to decide based on performance factors like longevity (Lip IV) or shade range and brow usability (Fill & Fluff).

Customer satisfaction is higher for NYX Fill & Fluff (91) than NYX Lip IV (87). Fill & Fluff also has a higher average star rating (4.6/5) with 9,934 reviews, with recurring praise for natural-looking brows, smooth glide, and ease of use. Lip IV still performs well with 4.3/5 across 11,794 reviews, and buyers often love the shine, hydration, and stain effect. The most consistent negative theme for Lip IV is shade accuracy, while Fill & Fluff’s key negatives are smudging/fading and occasional brush/packaging issues.

Claim support slightly favors NYX Lip IV (83 vs 80). Lip IV’s key claims—wet shine, stain effect over time, and hydration—are broadly echoed in reviews describing glossy finish, comfortable feel, and lasting tint, although “12HR hydration” remains hard to verify from user comments alone. Fill & Fluff’s claims around filling, defining, and fluffing are supported by frequent feedback about fullness and natural results, but durability-related complaints (smudging and limited water/sweat resistance) can undermine “all day” expectations for some users.

Ethical transparency is stronger for NYX Fill & Fluff on score (88 vs 78). Both product listings include cruelty-free positioning acknowledged by PETA, and Lip IV also states a vegan formula. Beyond those points, the provided data doesn’t include deeper details (such as ingredient sourcing or packaging sustainability), so comparisons should be kept to what’s explicitly stated.
