Best SPF Lip Balms of 2025

Lip Balms with Broad Spectrum SPF to protect you in the sun

August 6th, 2025
Home > Gear Reviews > Sun Protection

As people who are outdoors year round, we at Treeline Review know that sun protection is essential. We wear our face and body sunscreens, our UPF-rated sun protective shirts, pants, and water wear, and you know we’re wearing hats with good coverage. But did you know that it’s also incredibly important to protect your lips from sun damage? 

The skin of your lips is thinner and more fragile than the skin on the rest of your body—and because it lacks oil glands, it’s especially vulnerable to dryness and damage (including sunburn!). While you may already be a fan of moisturizing lip balms, you may or may not know that sun protection for the lips is also essential. 

Prolonged exposure to UVA and UVB rays increases the risk of skin cancer (which, yes, you absolutely can get on your lips). Sun damage can also lead to actinic cheilitis, a precancerous condition marked by rough, scaly patches on the lips. Over time, UV damage can also break down the skin barrier, leading to discoloration and premature aging around the mouth. That’s where SPF lip balms come in.

Unfortunately, not all SPF lip balms are created equal, and as we searched for data, it was tough to find good information. We found that the recommendations currently out there are sparse and geared mostly toward people looking for lip makeup containing SPF. So we did what we always do: applied science and rigorous testing to the problem! 

We evaluated more than 17 of the top SPF lip balms on the market for wearability, longevity, moisturizing/drying qualities, taste, smell, meltiness, pocket-sized packaging, and other characteristics. After this absolute battery of tests (including testing them through different activities, wearing them for weeks, and leaving them for days in a hot car in July), we have some thoughts on the best SPF lip balms for most people.

*Note: As described below, the American Academy of Dermatology Association has the same recommendations for SPF lip balms as they do for all sunscreens: you should always be using SPF 30 and above. With this in mind, we only tested lip balms with a rating of SPF 30 or higher.

The Winners

Best overall SPF lip balm: Aquaphor Lip Repair Stick + Sunscreen

Aquaphor Lip Repair Stick + Sunscreen

SPF rating: 30
Key ingredients: Avobenzone (3%), Homosalate (9%), Octisalate (4.5%), Octocrylene (9%)
Price: $5.50/stick on Amazon
What we liked: Neutral scent and flavor, hydrating, non-shiny, didn’t melt in our pocket, didn’t melt in the car
What we didn’t like: Bulky packaging, not the cheapest (though not too expensive), some testers had to reapply frequently, not vegan

Aquaphor Lip Repair Stick + Sunscreen was the landslide favorite SPF lip balm in Treeline Review user testing. We wrapped each lip balm in blue tape so our seven testers of different skin tones, levels of hairiness, and scent preferences wouldn't know the brand of lip balms they were testing. The Aquaphor came out on top for nearly everyone. It’s hydrating without feeling heavy, looks non-shiny, and has the waxy texture you’d expect of a typical lip balm. It has no added fragrance or color, and it doesn’t taste overwhelmingly of chemicals. It’s not the absolute cheapest of SPF lip balms, but it’s certainly on the more affordable side. There's a lot to love with this lip balm and the best SPF lip balm is the one that you'll use.

Aquaphor Lip Repair Stick + Sunscreen

This lip balm survived two days in a hot car (90+ degrees inside) without melting or even noticeably sweating. Online reviews agree: across many retailers and review sites, Aquaphor Lip Repair Stick + Sunscreen is one of the most frequently-recommended SPF lip products out there. 

The biggest drawback we found was the product’s longevity, with the lip balm rubbing or washing off relatively easily. While the packaging is slightly bulkier than we’d prefer, this wasn’t a dealbreaker, as it was still among many testers’ top picks. As one tester noted, Aquaphor Lip Repair Stick + Sunscreen is “slightly fancier than a basic lip balm,” and we appreciate its straightforward, affordable effectiveness.


Best affordable SPF lip balm: Blistex Five Star Lip Protection SPF 30

Blistex Five Star Lip Protection SPF 30

SPF rating: 30
Key ingredients: Avobenzone (3%), Homosalate (15%), Octisalate (5%)
Price: $2.44/stick on Amazon
What we liked: Affordability, non-drying, neutral taste, minimal scent
What we didn’t like: Not great longevity, not particularly hydrating, application not as smooth as some others, not vegan

If you’re someone who needs a tube of SPF lip balm in every bag and drawer, Blistex Five Star Lip Protection SPF 30 is the one for you. It’s one of the most affordable SPF lip balms on the market, and unlike many similarly priced products, it doesn’t smell terrible or taste overwhelmingly of chemicals.

Blistex Five Star Lip Protection SPF 30

Overall the experience of this product is…nothing special. Testing notes included words like “standard,” “basic,” and, my favorite, “uneventful.” The smell is vaguely sweet but not too strong, and most people found the taste neutral. 

The lip feel is the waxy texture of a typical drugstore lip balm. It’s not really hydrating, but neither is it drying. It did not get squishy in our pockets over the course of the day. It did not melt after many hours in a hot car. It was no one’s favorite, but it was not polarizing, and no one hated it! For an absolutely average and incredibly cost-effective SPF lip balm experience, Blistex Five Star Lip Protection SPF 30 is your best bet.


Best mineral SPF lip balm: TiZO Lip Protection SPF 45

TiZO Lip Protection SPF 45

SPF rating: 45
Key ingredients: Zinc Oxide 5.5% Titanium Dioxide 4%
Price: $11.50/stick on Amazon
What we liked: Very slight tint but no white cast, moisturizing, pleasant lightweight texture, pocket- sized, not much fragrance
What we didn’t like: Mixed feelings on longevity, slight chemical taste, sweated a bit after several hours in a hot car, on the expensive side

Mineral SPF lip balms–those using only zinc oxide and/or titanium dioxide as their active ingredients–are, like all mineral sunscreens, hard to make completely clear. Many of the mineral SPF lip balms we tried left a white cast, but Tizo Lip Protection SPF 45 had the least white cast of all the mineral products we tried. Though it looks light brown in the tube, it applies with a slight but not particularly noticeable tint, even on darker skin tones. One tester described it as “natural-looking.”

TiZO Lip Protection SPF 45

Tizo Lip Protection SPF 45 does have a slight fresh scent, which some testers found citrusy and others minty. Overall, the smell was very subtle, and most people found it to have a neutral taste, though some thought it tasted chemical-y. Online reviews across retail sites, too, find Tizo Lip Protection to be effective, neutral-tasting, and moisturizing. We also liked that this is a pocket-sized tube, about the size of an original Chapstick. 

The biggest drawback noted in testing was the product’s longevity, with several testers noting that it didn’t seem to last too long on the lips, particularly after drinking water. It sweated a bit of oily liquid after several hours in a hot car, though it didn’t melt. 

Some online customer reviewers also dislike the fact that it contains aluminum-based compounds, which have not been proven to have negative health effects but around which there is a great deal of discourse and currently-active research. If this is an issue for you, our runner-up mineral SPF lip balm, Burt’s Bees SPF 30 Lip Balm, has a slightly greater white cast and more noticeable scent but no aluminum. 


Best liquid/gel SPF lip balm: Cay Skin Isle Lip Balm SPF 30

Cay Skin Isle Lip Balm SPF 30

SPF rating: 30
Key ingredients: Avobenzone (3%), Octisalate (5%), Octocrylene (10%)
Price: $16.00/tube on Amazon
What we liked: Pleasant smell, hydrating, doesn’t taste chemical-y, stays on longest of liquid-type balms, doesn’t melt
What we didn’t like: Looks shiny, can feel sticky/heavy

Treeline testers’ favorite liquid or gel-type lip balm was Cay Skin Isle Lip Balm SPF 30. We were using the clear version, although it also comes in multiple shades if that’s your preference. All tints have a flavor described as “vanilla brown sugar” which smelled like…chocolate? Vanilla? Either way, it didn’t taste like sunscreen, which we appreciated. The majority of other liquid-type SPF lip balms we tried tasted strongly of chemicals. 

Many people love the smooth application and glowy finish of liquid lip balms and the fact that these won’t melt when you keep them in your hot car/pocket/pack.

Cay Skin Isle Lip Balm SPF 30

Liquid lip balms–that is, ones that you squeeze out of a tube rather than apply from a stick–are polarizing. The gel-like liquid formula makes some people feel like they don’t last as long, and the shiny finish of many of these products can be off-putting if that’s not what you’re expecting. 

In our testing, most liquid-type lip balms tended to have poor longevity, with the more lightweight products feeling like they dissolved immediately when we drank water. Cay Skin had the best longevity of the liquid-type lip balms we tried, largely because it felt thicker and stickier than competitors. We wore it on a 4-hour bike ride and despite frequently drinking water from a bike water bottle, it stayed in place.

Although the Cay is on the expensive side, we found ourselves needing to reapply it less frequently than other liquid-type lip balms, which made it feel like a better value.

In short, this product is a liquid/gel that you apply by squeezing it out of a tube–and of that category of lip balm, it was our favorite. It has a distinct sweet scent, a relatively neutral flavor, and a shiny finish. Its thick, sticky consistency made it more moisturizing and longer-wearing than comparable products. If you’re someone who appreciates a thicker, more persistent liquid lip balm and you like (or at least don’t mind) shiny lips, this is a great SPF lip balm to try.


Best reef-safe SPF lip balm for days in the water: Badger Mineral Sunscreen Face Stick SPF 35

Badger Mineral Sunscreen Face Stick SPF 35

SPF rating: 35
Key ingredients: Non-nano Zinc Oxide 22.5%
Price: $10.99/stick on Amazon
What we liked: Reef-safe, neutral scent and flavor, hydrating, excellent longevity & water resistance, dual purpose lips/face stick
What we didn’t like: Stick is larger than most lip balms, white cast, on the expensive side

Whether we’re boating, paddleboarding, surfing, or swimming, when it comes to days on and/or in the water, longevity and water resistance are essential in our sun protection. We also want a product that we’re sure won’t cause harm to freshwater or saltwater wildlife. That’s why our favorite SPF lip balm for days on the water is Badger Mineral Sunscreen Face Stick SPF 35.

Badger Mineral Sunscreen Face Stick SPF 35

Badger is a brand that makes several products we love for their short, reef-safe ingredient lists (plus being a woman-owned brand, B-corp, and made in the USA). The Badger Mineral Sunscreen Face Stick SPF 35 contains only zinc oxide, extra virgin olive oil, beeswax, cocoa butter, shea butter, and sunflower Vitamin E (most of these are certified organic and non-GMO). It’s moisturizing, long lasting, water resistant, and although it does leave a bit of a white cast, it’s much less noticeable than many other mineral SPF products. While it has no added fragrance, it has a slight neutral scent that didn’t bother most people.

While the size of this tube is larger than we typically want for an SPF lip balm, we appreciate that the larger size means we can use this sunscreen on our cheeks, nose, ears, and the rest of the face as needed (we also like this product for SPF reapplication during hikes and snow sports). Remember, if you’re swimming or sweating, you need to reapply at least every 80 minutes!


Other SPF Lip Balms We Tested

Overall Honorable Mention SPF lip balm: Panama Jack Sunscreen Lip Balm SPF 45

Panama Jack Sunscreen Lip Balm SPF 45

SPF rating: 45
Key ingredients: Avobenzone (3%), Homosalate (3%), Octinoxate (7.5%), Octisalate (5%) 
Price: $4.23/stick on Amazon

Panama Jack Sunscreen Lip Balm SPF 45 is an extremely popular product that gets stellar reviews across online retailers. We tried the vanilla flavor, and we liked it best of the flavored SPF lip balms we tried. The taste and smell were pretty mild, the taste wasn’t chemical-y, and the product was hydrating without being shiny or heavy. It’s also an extremely affordable pick, around $4 when you buy a 4-pack.

Panama Jack Sunscreen Lip Balm SPF 45

However, it is flavored, which is generally more polarizing than non-flavored products. It also contains octinoxate, which early research suggests could have hormone disrupting effects, and we don’t love that even if it’s not a conclusive medical recommendation at the moment. Overall, though, this is a pleasant and extremely well-liked product across the internet, and it’s our runner-up for best SPF lip balm.


Mineral Honorable Mention SPF lip balm: Burt’s Bees SPF 30 Lip Balm

Burt’s Bees SPF 30 Lip Balm

SPF rating: 30
Key ingredients: Zinc oxide 12%
Price: $4.33/stick on Amazon

Burt’s Bees SPF 30 Lip Balm was a close runner-up for Best Mineral SPF Lip Balm. It’s the #2 bestselling SPF lip balm on Amazon, it’s half the price of Tizo, and its white cast is barely more noticeable than our winner. It feels a bit thicker than Tizo when applied, but some testers liked the slightly weightier feel. While it wasn’t a universal favorite in our testing–the Tropic Like It’s Hot flavor was popular, the other flavors less so–it was pretty well-liked overall, and definitely a product we’d recommend if you want a more affordable mineral SPF lip balm.

Burt’s Bees SPF 30 Lip Balm

Mineral lip balms like Burt’s Bees SPF 30 Lip Balm, TiZO Lip Protection SPF 45, and Badger Mineral Sunscreen Face Stick SPF 35 are all good choices for kids.

Mineral lip balms like Burt’s Bees SPF 30 Lip Balm, TiZO Lip Protection SPF 45, and Badger Mineral Sunscreen Face Stick SPF 35 are all good choices for kids. Mineral sunscreen filters like zinc oxide and titanium dioxide are generally gentler and less likely to cause irritation or allergic reactions than chemical filters.


COOLA Organic Liplux Lip Balm SPF 30

SPF rating: 30
Key ingredients: Avobenzone 2.9% Octisalate 4.9% Octocrylene 7.6%
Price: 
$12.00/stick

This SPF lip balm, although at the top of several lists we found online, was only fine. Not markedly better as a lip balm than our winner, Aquaphor. We also disliked the bulky packaging, which has a luxurious heft but which is utterly unnecessary, since the actual balm is just the size of a regular stick of lip balm.

COOLA Organic Liplux Lip Balm SPF 30


Banana Boat Sport Ultra SPF 50 Lip Sunscreen

SPF rating: 50
Key ingredients: Avobenzone 3.0% Homosalate 10.0% Octisalate 5.0% Octocrylene 10.0%
Price: 
$3.25/stick

The Banana Boat Sport Ultra SPF 50 Lip Sunscreen is affordable, but it tastes like chemicals and wasn’t our favorite.

Banana Boat Sport Ultra SPF 50 Lip Sunscreen


Sun Bum SPF 30 Sunscreen Lip Balm 

SPF rating: 30
Key ingredients: Avobenzone 3% Homosalate 10%,Octisalate 5% Octocrylene 8%
Price: 
$3.33/stick

We had mixed feelings on this one. Overall the flavors were polarizing (some liked, some disliked), and as a lip balm it was fine but not better than competitors.

Sun Bum SPF 30 Sunscreen Lip Balm 


Sun Bum SPF 30 Mineral Sunscreen Lip Balm

SPF rating: 30
Key ingredients: Zinc oxide
Price: 
$3.95/stick

Affordable mineral SPF lip balm, and pleasant enough, but tasted a bit chemical-y and had a pretty noticeable white cast.

Sun Bum SPF 30 Mineral Sunscreen Lip Balm


Vacation AriZona Iced Tea SPF 30 Lip Balm

SPF rating: 30
Key ingredients: Avobenzone (3%) Homosalate (5%) Octisalate (3%) Octocrylene (10%)
Price: 
$4.00/stick

Similarly to Sun Bum, these were polarizing, with testers split on flavors. Vacation has some of the best-reviewed flavored SPF lip balms online, and the Mucho Mango flavor was among several testers’ favorites. So not a universal winner for us, but a viable choice if you want to try a flavored lip balm. 

Vacation AriZona Iced Tea SPF 30 Lip Balm


Supergoop! PLAY Lip Balm SPF 30

SPF rating: 30
Key ingredients: Avobenzone (3%) Homosalate (10%) Octocrylene (10%) Octisalate (5%)
Price: 
$12.00/tube

Some testers had neutral experiences with this liquid SPF lip balm, but many thought it was too thin/watery, tasted/smelled chemical-y, and/or changed the color of their lips. It’s also on the expensive side.

Supergoop! PLAY Lip Balm SPF 30


Hello Sunday The One For Your Lips SPF 50 Hydrating Lip Balm

SPF rating: 50
Key ingredients: Octocrylene (9%) Homosalate (7%) Octisalate (5%) Avobenzone (3%)
Price: 
$12.00/tube

This liquid SPF lip balm got mixed reviews from testers, with some liking it quite a bit and others feeling lukewarm. We had a hard time finding it across the internet, though: we bought ours from Sephora, but it looks like the similarly-named product on Amazon has different packaging, and maybe isn’t the same thing? Confusing.

Hello Sunday The One For Your Lips SPF 50 Hydrating Lip Balm


SPF rating: 30
Key ingredients: Titanium Dioxide 7% (Non-Nano), Zinc Oxide 6% (Non-Nano)
Price: 
$5.49/stick

We appreciated this mineral SPF lip balm’s reef -safety, but it left an extreme white cast. Good longevity and water resistance though.

It is worth pointing out that not all Stream2Sea lip balms have a SPF rating. Many of the widely available 2-packs contain the Hydrate version, which is not SPF rated. This 3-pack contains only the SPF version, but many multi-packs contain at least one non-SPF lip balm, so be aware of this before you purchase.

Stream2Sea Naturally Naked Lip Balm SPF 30


Dermatone Mineral Lip Balm SPF 30

SPF rating: 30
Key ingredients: Zinc oxide (15%)
Price: 
$4.00/stick

This was ok as a mineral SPF lip balm, not too bad of a white cast, but did taste a bit chemical-y. Maybe a runner-up to the runner-up.

Dermatone Mineral Lip Balm SPF 30

For literally any and every other type of SPF lip balm, lip gloss, or other lip product not on this list:

Is it SPF 30+ and protective against UVA/UVB rays? Go ahead and use it. It’ll work. They’re not in this article because they didn’t have as many user experience factors to recommend them, or they’re expensive, or any number of things depending on the person. However, they’re still 100% functional as sunscreen. If you’ll wear them, buy them!


How to choose a SPF lip balm

Our testers put in a lot of work to determine the best SPF lip balms.

Our testers put in a lot of work to determine the best SPF lip balms.

According to the American Academy of Dermatology Association, the general rules of sunscreen also apply to SPF lip balms. Use a product containing SPF 30 or higher. Apply to the whole lip area at least every 2 hours, and more frequently if you’re swimming or sweating (or, since it’s lip balm, eating or drinking).

Also, if you’ve ever felt like lip balms can leave your lips feeling even dryer after a bit, you’re not alone. This is often down to the ingredients–or rather, the combination of ingredients. You may be familiar with chemicals called humectants, which draw in moisture from the air—these are ingredients like glycerin, hyaluronic acid, aloe vera, and propylene glycol. While moisture is a good thing, balms made only with humectants draw in moisture but don’t lock it in, so lips may feel hydrated at first but quickly dry out again. This can lead to a feeling of perpetual dryness and constant reapplication. 

To truly nourish lips, look for formulas that combine humectants with chemicals called occlusives, which seal in the moisture that humectants attract. Occlusives include ingredients like shea butter, cocoa butter, squalane, beeswax, and petrolatum, which create a physical barrier preventing moisture loss. Also, be wary of added fragrances, parabens, or "plumping" ingredients like cinnamon and peppermint, which can irritate lips and worsen dryness, and in rare cases cause allergic reactions.

Pro Tip: if you’re new to SPF lip balms and you’re not sure where to start: We found it interesting that in Treeline Review testing, SPF lip balms from brands known for lip balms were generally preferred over those from brands known for sunscreen (ie. Aquaphor, Blistex, Burt’s Bees, and Cay Skin were better liked overall than Sun Bum, Supergoop, or Banana Boat). Flavored products and liquid lip balm products were more polarizing than their unflavored stick peers. So if you’re looking for an SPF lip balm for the first time, we suggest you look for (1) an SPF product from a company whose lip balms you already enjoy, and/or (2) an SPF lip balm stick without added fragrances or flavors.


FAQ

  • Ultimately everyone’s skin is different, and no single sunscreen product works for everyone. In general, when it comes to sensitive skin, though, we know that customers want both sun protection and a product that won’t cause stinging, irritation, breakouts, drying, flaking, or other negative effects. SPF lip balms that contain chemical filters, fragrances, and other skincare chemicals can cause these types of irritation to sensitive, dryness-prone, and/or eczema-prone skin, especially on the thin skin of the lips. Although there’s no single solution, experts agree that those with sensitive skin should look for:

    • Mineral (i.e., zinc oxide or titanium dioxide) formulas, since chemical filters tend to cause more irritation than their mineral peers 

    • Oil-free and fragrance-free products, since these ingredients can irritate sensitive skin 

    • Ingredients like hyaluronic acid, ceramides, squalane, and/or vitamin E, if dry skin or eczema is an issue

    Among the products reviewed here, TiZO Lip Protection SPF 45, Badger Mineral Sunscreen Face Stick SPF 35, and Burt’s Bees SPF 30 Lip Balm are good mineral SPF lip balms to try. Aquaphor Lip Repair Stick + Sunscreen is a chemical SPF lip balm with no added fragrance or color, so that’s a good option as well.

  • As an outdoor gear review site, we wanted to evaluate SPF lip balms with outdoor activities in mind. Since tinted lip balms, lipsticks, and lip glosses tend to appeal mostly to people who wear makeup, which is often not practical or feasible for outdoor activities, we limited our testing to products that aren’t intended to add color to the lips. However, many people may want a single SPF lip balm for day-to-day use and outdoor recreation, so we did a little research on tinted SPF lip balm for those who prefer it.

    In our research, it was clear that Colorescience Sunforgettable Color Balm SPF 50 was the internet’s favorite tinted SPF lip balm (though it’s on the pricey side). On the more affordable side, MDSolarSciences Tinted Lip Balm SPF 30 also comes in a range of colors and receives excellent reviews (it’s the #3 best-selling lip sunscreen on Amazon). 

    Among the products we tested, Cay Skin Isle Lip Balm SPF 30 comes in a variety of shades, as well as the clear tint reviewed above.

  • Sure, if you want to. The main drawbacks of using face sunscreen or body sunscreen on your lips are experiential: sunscreens meant for your face or body may have ingredients like fragrances, alcohols, or textural elements that may make them unpleasant to use on the lips or cause irritation. They also tend to taste strongly of chemicals. 

    Functionally speaking, since they’re meant for the skin of the body or face, they will offer the same protection but won’t stay on the lips as long, particularly if you’re eating or drinking. So if you’re using lotion sunscreen on your lips, the “every 2 hours or after swimming or sweating” rule isn’t quite the same–make sure you’re re-applying much more frequently.

  • The American Academy of Dermatology recommends everyone use a sunscreen that offers:

    •  Broad spectrum sun protection (i.e., protects against UVA and UVB rays)

    •  SPF 30 or higher

    •  Water resistance

    Buy a sunscreen that meets the requirements above (this info is usually on the front of the bottle). Every single sunscreen we review meets those basic requirements. Once you have it:

    • Apply more than you think you need (most people only use 25-50% of the recommended amount). 

    • Use sunscreen literally every day on every part of your body that will see the sun. 

    • Make sure you’re applying enough and rubbing it in to ensure full coverage.

    • Reapply every two hours when outdoors, and after swimming or sweating. 

    • If you’re going to be outside for a while, wear clothing designed for sun protection and a sun hat. 

    And that’s it. Go forth, apply, and prosper without skin cancer! If you want more fun & helpful facts about sunscreen, please enjoy the AADA’s website and the Skin Cancer Foundation.

How We Researched and Tested

To choose which SPF lip balms to test, we considered:

  • AADA requirements for sunscreens: All of our picks had to offer broad-spectrum UVA/UVB rays protection and SPF 30+. 

  • Price: You can spend $40 on a tube of lip balm (and power to you if you want to), but we wanted these to be more accessible. Everything here is $16 or under.

  • Availability: Readily available at lots of major stores and online. If you can’t grab it on your way to the beach/trail/party, what’s the use?

  • Expert recommendation: Do dermatologists and other skin experts recommend it?

  • User experience: How does it feel on the lips? Is it moisturizing, drying, or irritating? Does it absorb quickly and invisibly, regardless of skin tone? Does it have a major fragrance? Does it taste chemical-y? Will it melt in your pocket/pack/car? Do people like using it? 

Once we’ve compiled an initial list of products to test, we gathered expert input from dermatologists, scientists, doctors and other professionals (the American Academy of Dermatology Association, Environmental Working Group, Haereticus Lab, etc.); professional review sources (like Wirecutter and Consumer Reports); periodicals and informational sites (like Healthline, Men’s Health, Byrdie, AARP, Self, Into the Gloss, and others); user reviews on retail sites (like Amazon, Target, Sephora, REI, etc.); and a group of Treeline Review testers. These fellow testers tried out the products across a range of skin tones, locations, and outdoor activities. 

In addition to long-term testing, heat testing, and other experiments, seven Treeline Review testers blind-tested 16 SPF lip balms, identifying each product only by number. Then, they each received a data sheet for every lip balm where they rated lip balms using the same criteria: 

  • Flavor/scent

  • Hydration/moisturizing

  • How it looks/white cast

  • Water resistance

  • Longevity

  • Packaging

  • Other notes

Testers assigned a numeric value (1-10) for each category and were also encouraged to leave qualitative notes. To test water resistance, each tester applied the lip balm and then took a drink of water. After applying, each tester was provided with face wipes to remove the previous lip balm before applying the next lip balm. 

Testers were chosen to represent a variety of skin tones, skin types, facial hair, and preference for scented products. 

Remember that no sunscreen can completely block damaging UV rays from the sun, especially if misapplied (i.e., you don’t use enough or don’t reapply)! Wear sun-protective hats and clothing if you’re going to be out there for a while. See our guide to the Best Sun Shirts and Best Sun Hats for our recommendations.
