The full review.
There is a specific moment in beauty culture when a product stops being a product and becomes a behavior. For Summer Fridays’ Lip Butter Balm, that moment arrived somewhere around 2022, when TikTok transformed a simple flavored lip balm into something people collected, displayed, and made content about the way previous generations did with MAC lipsticks or Clinique Black Honey. One Lip Butter Balm reportedly sold every eight seconds at peak velocity. People didn’t just have one — they had Vanilla in their purse, Iced Coffee in their desk drawer, and Pink Sugar in their gym bag.
This matters because the product’s cultural impact substantially outpaces its formulation complexity, and understanding that gap is key to understanding whether it’s worth your $24. Let’s be clear about what’s in the tube: shea butter, murumuru seed butter, a cocktail of synthetic waxes and polymers for structure, sodium hyaluronate for humectant hydration, vitamin E for antioxidant protection, and vanillin for the signature sweet scent. It’s a well-made lip balm. It is not a revolutionary formulation.
What Summer Fridays did get right — genuinely right — is the textural experience. The Lip Butter Balm feels different from both traditional waxy balms and thin lip oils. It has a thick, cushiony density that melts on contact with warm lips, leaving a buttery coating that’s plush without being heavy. The curved applicator tip on the squeeze tube makes application feel intentional and precise rather than the slapdash finger-dip of a pot balm. These are design decisions, not ingredient innovations, and they matter enormously in a category where the physical experience of applying the product is half the value.
The murumuru seed butter deserves specific credit here. While shea butter provides the occlusive backbone, murumuru — a Brazilian palm seed butter rich in lauric and myristic fatty acids — contributes the smooth, non-waxy glide that distinguishes this from grittier natural balms. It’s the ingredient responsible for that satisfying slip, and it works beautifully alongside the polymer system that gives the balm its structure without making it feel plasticky.
Sodium hyaluronate is the ingredient that earns this the ‘skincare’ descriptor in ‘skincare lip balm.’ Applied beneath the occlusive butter layers, it draws ambient moisture to the lip surface, providing active hydration rather than just passive sealing. The result is a temporary plumping effect — lips look fuller and smoother immediately after application. Whether this represents a meaningful advance over any well-formulated lip balm with good humectants is debatable, but the inclusion is thoughtful and it does what it claims.
The honest performance picture: this balm delivers about 1-2 hours of glossy, hydrated perfection. The shine fades first, leaving a more matte butter layer that persists somewhat longer. Eating or drinking resets the clock entirely. If you’re expecting the kind of stain-like longevity that some lip tints offer, this will disappoint — it’s fundamentally a treatment balm with a cosmetic finish, not a long-wear lip color. The tinted variants (Pink Sugar, Cherry, Iced Coffee) offer a whisper of color that’s flattering but too sheer to replace any actual lip product.
As an overnight lip mask, the Lip Butter Balm genuinely excels. A thick layer applied before bed creates a sustained occlusive barrier that prevents the transepidermal water loss that causes morning lip dryness. After two to three nights of consistent use, chronically chapped lips show noticeable improvement. This may be its best use case — the one that most justifies the ‘treatment’ positioning.
The packaging deserves both praise and critique. The aluminum tube is sleek, recyclable, and compact enough for any bag. The curved tip is a smart design touch. But the tube itself can be stiff when new, requiring uncomfortable squeezing force, and multiple users report leaking issues — product oozing from around the cap after pressure changes (flights, gym bags) or in warm weather. For a brand built around travel and on-the-go convenience, this is an ironic weak point.
The flavor and shade range is the product’s most commercially savvy element. Vanilla, Iced Coffee, Pink Sugar, Brown Sugar, Cherry, Hot Cocoa — these aren’t just flavors, they’re moods. Summer Fridays understood that lip balm in the social media era is an expressive purchase, and the dessert-beverage naming convention encourages collecting rather than committing to one. The limited editions create FOMO-driven urgency that keeps the product culturally relevant season after season.
At $24 for half an ounce, the Lip Butter Balm sits at a premium for its ingredient simplicity. The core formula — butters, waxes, polymers, a single humectant — is something that could be replicated at a lower price point. What you’re paying for is the specific textural execution, the applicator design, the shade curation, and yes, the brand cachet. For committed fans who use this daily and reapply multiple times, the per-use cost adds up. The mini sets offer a more economical entry point for sampling shades.
Summer Fridays’ Lip Butter Balm is a product that’s easier to enjoy than to justify on ingredient merits alone. It feels wonderful, looks beautiful on the lips for an hour or two, and has earned its cultural moment through smart design and shrewd flavor marketing. Whether that’s worth $24 depends on how much you value the experience of application versus the technical sophistication of what’s inside the tube.

The science.
The Science
The Lip Butter Balm uses a simple humectant-occlusive system for lip tissue. Lip skin differs from facial skin: it lacks sebaceous glands, has a thinner stratum corneum, and has higher transepidermal water loss (TEWL). Research in the International Journal of Cosmetic Science shows that lip products combining humectant and occlusive ingredients reduce TEWL better than either approach alone.
Sodium hyaluronate — the low-molecular-weight salt form of hyaluronic acid — acts as the humectant layer to bind water at the lip surface. Studies show topical sodium hyaluronate improves skin hydration and temporarily reduces fine line appearance through tissue plumping, making lips look smoother and fuller.
Shea butter and murumuru seed butter provide the occlusive layer. Shea butter (Butyrospermum parkii) contains about 60% oleic and stearic fatty acids and shows anti-inflammatory properties in vitro due to its cinnamic acid esters and lupeol content. Murumuru butter (Astrocaryum murumuru) has about 47% lauric acid and about 25% myristic acid, which creates a smooth, spreadable texture and strong occlusive properties. This combination builds a lipid barrier that slows moisture evaporation while sodium hyaluronate draws moisture from the environment.
Tocopherol (vitamin E) works as an antioxidant to protect lip tissue from UV-induced free radical damage and as a stabilizer to prevent the natural butters from oxidative rancidity.
Dermatologist Perspective
Dermatologists often recommend occlusive lip balms for patients with chronic cheilitis (dry, cracked lips); the shea-murumuru butter combination in this formula provides effective barrier function. Board-certified dermatologists note that sodium hyaluronate differentiates this from simpler petroleum-based balms, though its benefit in a leave-on lip product depends on environmental humidity. Dermatologists frequently favor butter-based formulas like this one because they lack common lip irritants — menthol, camphor, phenol, and salicylic acid — which appear in many drugstore lip balms and can worsen dryness. For patients with contact dermatitis on the lips, dermatologists may flag vanillin and BHT as potential sensitizers requiring patch-testing.
Where it fits in your routine.
Squeeze a small amount from the tube and glide the curved applicator across lips. For daytime, one thin layer gives a glossy, hydrated finish — reapply every 1-2 hours or after eating and drinking. For overnight lip treatment, apply a thick layer as your last step before bed and leave it on while you sleep. Layer it over lip liner for a tinted, glossy look. Store at room temperature to keep the texture right — refrigeration makes it too stiff, and heat causes leaking.
At $24 for 0.5 ounces, the Lip Butter Balm sits at the high end of the lip balm market. The ingredient list — butters, waxes, one humectant, vitamin E — works like formulas costing a third as much. The premium comes from the texture, the applicator design, and the collectible shade curation. The mini sets ($28-32 for four 0.16 oz tubes) lower the entry price for sampling. Daily users reapply 3-4 times, so one tube lasts 2-3 months. This makes the monthly cost around $8-12 — reasonable for a daily beauty product, but not a bargain. Summer Fridays is an established indie brand, but the formula lacks the clinical weight to justify a true prestige price.
Choose this if you want a thick daily lip balm that hydrates and leaves a glossy finish. It works well for lip balm collectors, frequent travelers needing a compact multitasker, and people with dry lips from air-conditioned environments.
Budget-conscious shoppers who find $24 too high for a simple lip balm formula. Users wanting long-lasting lip color—the tints are too sheer to replace a lipstick or tinted balm. People sensitive to vanillin, BHT, or synthetic waxes should patch-test first.
Product details.
Thick, buttery, and cushiony — denser than a typical lip gloss but smoother than a traditional waxy lip balm. The angled tube tip glides on easily and leaves a plush, non-waxy coating on the lips.
The original Vanilla shade has a sweet, subtle vanilla pudding-like scent from vanillin. Each shade variant has its own dessert or beverage-inspired flavor — Cherry, Iced Coffee, Pink Sugar, Brown Sugar, etc. Noticeable but not overwhelming.
Sleek aluminum squeeze tube uses a curved angled applicator tip for precise lip application. Minimalist Summer Fridays aesthetic uses shade-specific pastel colorways. It is recyclable. The design is compact and portable, but some users report the cap sits loosely and the product leaks under pressure.
The first application gives immediate glossy shine and a plump, cushiony feel. The thick texture differs from traditional balms; it is more emollient. The vanilla scent is subtle and pleasant. There is no tingling or adjustment period. You may need to squeeze the tube firmly for the first few uses.

The backstory.
Launched in 2020 as Summer Fridays' second major product after the Jet Lag Mask, the Lip Butter Balm started with a single Vanilla shade and grew into the brand's bestseller. It became a TikTok phenomenon around 2022-2023, with one unit selling every eight seconds at peak velocity. The shade range expanded from one to over ten permanent and limited-edition variants, making it Sephora's top lip product and earning over 2 million platform favorites.
About Summer Fridays
Established Brand (5–20 years)Summer Fridays was co-founded by influencers Marianna Hewitt and Lauren Gores Ireland in 2018. The Lip Butter Balm became the brand's bestseller and one of Sephora's top-selling lip products, reporting one unit sold every eight seconds at peak demand. The brand has Leaping Bunny certification but relies more on consumer reception than clinical research.
Common myths.
The Lip Butter Balm hydrates for the entire day.
The glossy finish and hydration last 1-2 hours before you reapply. Occlusive butters prevent moisture loss during that time, but this topical balm does not change lip tissue — you need consistent reapplication for all-day comfort.
The hyaluronic acid in this balm plumps lips like a filler.
Sodium hyaluronate pulls moisture to the lip surface. It creates a temporary plumping effect via hydration, not volumization. This plumped appearance fades as the product wears off. Any lip balm with good humectants works similarly.
FAQ.
Which Summer Fridays Lip Butter Balm shade is best?
The original Vanilla is the bestselling shade. It is clear with a sweet vanilla scent and fits most people. Pink Sugar offers a sheer pink tint for most skin tones. Iced Coffee and Brown Sugar provide a subtle nude warmth.
Is the Summer Fridays Lip Butter Balm actually hydrating?
Yes — shea butter and murumuru butter create an occlusive moisture barrier, and sodium hyaluronate draws hydration to the lip surface. This effect is temporary and needs reapplication every 1-2 hours. For chronically dry lips, use a thick layer as an overnight lip mask for best results.
Does the Summer Fridays Lip Butter Balm have SPF?
No — the Lip Butter Balm does not contain sun protection. If you need lip SPF, layer a dedicated SPF lip balm underneath before applying the Lip Butter Balm on top for gloss and hydration.
Is the Summer Fridays Lip Butter Balm safe during pregnancy?
The Lip Butter Balm has no retinoids, salicylic acid, or other pregnancy-flagged actives. Third-party skincare resources list it as pregnancy-safe. The formula uses simple butters, waxes, hyaluronic acid, and vitamin E — but consult your physician if you have specific concerns.
Why is my Summer Fridays Lip Butter Balm hard to squeeze?
The thick butter-based formula is stiff when new or stored in cool temperatures. Warm the tube between your hands for 10-15 seconds before squeezing. The product flows easier after a few uses once the tube loosens.
How long does the Summer Fridays Lip Butter Balm last on lips?
The glossy finish lasts 1-2 hours without eating or drinking. The hydrating base layer lasts longer, around 2-3 hours. Reapply after meals. As an overnight mask, a thick layer provides hydration through the night.
Is the Summer Fridays Lip Butter Balm vegan and cruelty-free?
Yes — the Lip Butter Balm is Leaping Bunny certified cruelty-free and contains no animal-derived ingredients. It is also gluten-free. Every shade variant uses a vegan formula.
