I've Been Diving for 22 Years—These Are the 8 Best Reef-safe Sunscreens I've Tried
I was 13 the first time I saw a coral reef. The endless blue of the ocean gave way to an explosion of color unlike anything I'd seen before. Colorful schools of fish moved around vibrant corals while the sun shone through, glittering like a stained glass window set aflame by the sun. In the 22 years since that moment, I've been fortunate enough to go snorkeling and diving all over the world, from the cold waters of Jeju Island in Korea to the warmth of the Indian Ocean in Seychelles and numerous places in the Caribbean.
Although coral reefs are still magical, there is an uncomfortable truth anyone who knows the ocean has to painfully acknowledge: Corals are dying. According to the National Park Service, swimmers leech an estimated 4,000 to 6,000 tons of sunscreen into the ocean every year, and sunscreen has been linked to coral bleaching—a phenomenon wherein coral loses its vibrant pigment and turns white over time, becoming weak and susceptible to starvation and death.
It's been a long time since I've seen a truly thriving reef; even the one I visited in middle school is mostly bleached now. Though we may not individually have the power to reverse climate change, there are smaller—albeit very significant—actions that we can take, like switching to reef-safe sunscreens. Since terms like 'reef-safe' are unregulated, consumers should look out for specific ingredients when choosing an eco-conscious sunscreen, especially oxybenzone and octinoxate. Now banned in places like Hawaii, Mexico, and Aruba, these ingredients aren't just harmful for marine life, but have also been linked to hormone disruption in humans. Other toxic ingredients to avoid include non-nano-sized zinc or titanium, parabens, and triclosan.
To keep coral reefs as healthy as possible while diving, I've tested out several reef-safe sunscreens. Keep scrolling for eight travel-friendly, reef-safe sunscreens I recommend that are perfectly sized for stowing in your carry-on luggage.
Thrive's Mineral Face SPF is the only reef-safe facial sunscreen I found that was able to replace my regular one. The formula states that it's made for sensitive skin, and it delivers on its promise. It's lightweight and soothing for my rosacea and acne-prone face. It also leaves no white cast. As a bonus, all Thrive products are plastic negative, meaning that the company recovers more plastic from the ocean than it uses to package its products. My only qualm with it is that the SPF is lower than I would like, and that the body sunscreen is too large to pack in a carry-on.
Since it costs nearly $30 for 2 ounces, I wouldn't use this product when I'm at the beach and need to reapply sunscreen around the clock. Instead, I'd use this for daily life and SPF touch-ups, and opt for longer-lasting options when I plan to be outside in the sun all day. It's important to remember that using reef-safe sunscreen is still important for protecting aquatic environments, even if you're not near the ocean—harmful chemicals from non-reef-safe sunscreens can seep into local water sources when you shower.
SurfDurt Mineral SPF is now one of my favorite facial sunscreens, especially because of its impressively short list of 10 ingredients, including organic cocoa butter, organic coconut oil, and natural iron oxide pigment. There is nothing on the list that I don't recognize, so I feel comfortable diving while wearing it, knowing I'm not harming the very reefs that I'm swimming next to.
I've also found that this product is perfect for kids. My three-year-old niece, who usually hates putting on sunscreen, loves it so much to the point where I have to tell her to save some for later. Since it's not a messy, runny liquid, she's able to put it on herself, making the SPF application process feel more like a game than an annoying pre-pool requirement. Since I have mixed skin, this sunscreen is a bit too greasy for me to use every day. But when I made my brother, another sunscreen hater, try it, he said that it worked well for his dry skin.
I love that you don't have to ever worry about the sunscreen spilling all over your suitcase or purse, and that you can reuse the cool bamboo and tin packaging to pack things like jewelry and pills once you're run out of product. If you've never used tin sunscreen before, try it out for yourself; you'll probably end up appreciating how nice and smooth it feels without leaving your hands gooey or greasy.
Hawaiian-based Kokua Sun Care contains natural, locally-grown ingredients like spirulina, noni, flower extracts, and seed oils; however, its formula also includes chemical ingredients. Despite being the most expensive sunscreen on the list, its texture isn't very smooth, so you'll have to thoroughly rub it in. That said, it has a high SPF, and it doesn't leave a white cast or have a strong smell, which are two factors that I believe justify the high price.
For the packaging, the company uses bio-based sugar cane that is chemically identical to polyethylene, making it easy to recycle. Because sugar cane absorbs more CO2 while growing than the amount that is released when making the packaging, this is considered a carbon-negative packaging solution, giving this sunscreen option bonus points for eco-friendliness.
Badger sunscreen is dermatologist-approved, and it's not hard to see why. The product is fairly lightweight and doesn't leave a white cast, which means you can reapply it multiple times without overwhelming your skin. It wins bonus points for its high SPF and relatively low price.
The brand's facial sunscreen is great as well, and it doesn't make my sensitive skin react. I could definitely see this becoming my to-go product for daily protection if I couldn't shell out $30 for the Thrive restock. I use the tin version in order to reduce plastic waste, but the company has a tube sunscreen with 50 percent recycled plastic packaging, and all products are made in solar-powered facilities within the U.S.
The thing I love the most about Raw Elements' SPF is that you can recognize everything on the ingredient list. Besides non-nano zinc oxide, you'll find ingredients like sunflower, organic beeswax, mango, green tea leaf extract, rosemary, and coffee. This gives the product a strong smell, but it's not a chemical one, so I actually prefer its scent to that of most 'regular' sunscreens.
Other positives are that it doesn't leave a white cast, and that it feels nourishing, especially if you have dry skin. While the product is supposed to be used on both the body and face, my sensitive face immediately started itching when I put it on. The rest of my body reacts well to it, though, so I'd recommend this as an affordable body sunscreen made with natural ingredients.
Besides having the coolest logo out of all the sunscreens on this list, Raw Love SPF earns points for being the smoothest tin sunscreen I've ever tried. Its ingredient list is short and mostly made up of organic ingredients, like coconut oil and shea butter, and it has a fresh, minty smell. This Maui-based brand was founded by a marine biologist, which explains its commitment and dedication to keeping things natural and healthy for both humans and sea life.
Unfortunately for me, this product is a bit too oily to put daily on my mixed-type skin, though Amazon reviews claim it works well with other skin types—some people even use it as a makeup primer. While the product's consistency is fantastic, it only comes in a 2-ounce or 4-ounce packaging, so if you need to keep it TSA-friendly, you'll have to opt for the smaller of the two. There is a minimal white cast that wasn't very noticeable on my pale skin, though it might be more obvious on darker skin tones.
Stream2Sea's sunscreen is not greasy and doesn't make my rosacea flare up—this alone immediately earned it a spot on this list. I also like that the product is biodegradable and packaged in recycled materials. The only downside is that it leaves a noticeable white cast, even after rubbing intensely. If this is a non-negotiable for you, I've found that the tinned balm version doesn't have this issue, so I'll certainly be making it my go-to for dive days when I mostly reapply to my hands and face.
Besides foregoing the use of harmful chemicals, the company claims to have developed a sunscreen product that actually helps corals—aptly named Coral Care—by providing nutrients that naturally exist in sea water, though this study is still being peer reviewed. Although the Coral Care sunscreen line isn't available on Amazon yet, you can purchase it on Stream2Sea's website.
While Blue Lizard's products are Hawaiian Act 104-compliant—meaning that they contain no octinoxate or oxybenzone—they do have more chemical ingredients than the other options on this list. Still, this sunscreen has a high SPF, works well for sensitive skin, and beats out the competition in terms of affordability. It was also the only reef-safe sunscreen that I could find at my local drugstore, making it more easily accessible than brands that you have to order online.
It is worth noting that it rubs clear when you first put it on, but then turns slightly white when you go into the water. Overall, I'd keep this as a last-minute or low-budget option for when you can't get any of the other recommended sunscreens—and despite this shortcoming, I'd definitely still choose it over products made with chemicals that are harming the ocean.

How Mastercard Helped Blenheim Palace Cut Costs with Reusable Cups
In an era when organizations are discovering that circular economy models can reduce costs and create new revenue streams, forward-thinking businesses are capitalizing on the shift from wasteful linear systems to more profitable circular alternatives. The transition from take-make-dispose models to circular systems represents one of the most profound operational shifts of the 21st century. Those who embrace it may discover competitive advantages. And when implemented thoughtfully, circular economy initiatives can create multiple layers of value that extend far beyond environmental benefits. Circular Innovation Blenheim Palace, a UNESCO World Heritage site in Oxfordshire, England, demonstrates how businesses can implement circular economy initiatives while improving operational efficiency, enhancing visitor experiences, and cutting costs. Two years ago, Blenheim Palace faced a common costly problem; it was spending over $100,000 annually on single-use cups that added to the many single-use cups reaching a landfill or an incinerator every day. Today it's achieved a notable 50% reduction in beverage packaging costs by implementing a deposit return scheme (DRS) with reusable cups, like other reusable cup deposit return schemes, such as in Denmark. 'The transition wasn't merely about sustainability metrics,' says David Green, head of innovation at Blenheim Palace. 'Our reusable cup scheme has significantly cut costs and fundamentally transformed our operations,' reimbursing customers rapidly and conveniently for returning their cups. 'The transition wasn't merely about sustainability metrics,' says David Green, head of innovation at Blenheim Palace. 'Our reusable cup scheme has significantly cut costs and fundamentally transformed our operations,' reimbursing customers rapidly and conveniently for returning their cups. The Mechanics of Circular Success Blenheim Palace's approach is elegant in its simplicity. Visitors pay $2.70 deposits to rent RFID-enabled reusable cups they will later return to reverse-vending machines. Circularity solutions provider re-universe assigns each cup a digital identity for data tracking and tracing throughout its usage. Blenheim Palace collects, washes, and reintroduces the cups into circulation—and visitors get secure, near-instantaneous refunds to their payment cards. 'With return machines streamlining the process,' Green says, 'we're achieving remarkable results that prove sustainable operations can be financially viable, too.' In a 12-month period, Blenheim Palace has cut 1,150 kg of carbon emissions and kept 320,000 single-use cups out of landfills. The Business Case for Circularity 'For circular initiatives to scale, the consumer experience must be seamless,' says Pratik Khowala, Mastercard's global head of transfer solutions. 'Our payments technology enables Blenheim Palace to offer near-instant deposit returns without requiring visitors to download apps or share additional banking information—a critical factor in achieving high participation rates, especially among international visitors.' Beyond environmental benefits, the financial case for this circular system is compelling. Blenheim Palace reports a 50% cost savings during the second year of implementation, including reduced waste management expenses and increased operational efficiencies. Each $2 reusable cup needs only four uses for its cost to break even, versus the $0.35 to $0.67 it spent for each single-use cup. The system also provides valuable data insights that allow continuous optimization—information that was absent from the previous model. 'The metrics we now track go well beyond basic environmental indicators,' Green says. 'We're measuring operational efficiency, visitor satisfaction, and return rates by location. This data allows us to continually refine the system for maximum impact and is leading us to invest more in the program. We're starting with hot cups, but we are planning to expand into cold cups and other packaging soon.' The Visitor Experience 'Visitor feedback has been overwhelmingly positive,' Green says. 'Guests specifically mention the reusable cup program in visitor surveys, noting how it aligns with their own values around environmental stewardship.' This alignment with consumer values represents an increasingly important competitive advantage for organizations across sectors. Retailers, manufacturers, hospitality providers, and service organizations across numerous industries and product categories can adapt these circular economy principles to their specific contexts. 'The technology behind the Blenheim experience can be applied to numerous circular economy initiatives beyond cups—from deposit-based redemption for reusable packaging to product buyback and peer-to-peer resale,' says Khowala. 6 Keys to Successful Implementation Blenheim Palace's initiative reveals six critical factors organizations should consider when they implement their own circular economy programs: 1. Consumer education: Clear communication about the process and its benefits drives participation. 2. Staff training and engagement: Frontline employees must understand the system to support it and encourage consumers to participate. 3. Frictionless user experience: Simplicity in participation—making deposits and returns as easy as possible—is nonnegotiable for high adoption. 4. Inclusivity: Systems must accommodate diverse user needs, including those of international visitors. 5. Optimized incentive structure: Deposit fees must balance motivation for returns without deterring participation. 6. Data-driven management: Real-time data visibility enables continuous improvement and optimization. 5 Strategic Implications for Leaders For executives considering circular economy initiatives, the Blenheim Palace case offers several clear takeaways: 1. Start with high-visibility waste streams: Focus initial circular economy efforts on visible, high-volume waste that resonates with stakeholders. 2. Design for user experience: Prioritize simplicity and convenience in circular systems to drive adoption. 3. Use technology appropriately: Digital tools should reduce friction, not add complexity. 4. Measure multidimensional value: Track environmental, financial, operational, and customer experience metrics. 5. Communicate authentically: Share transparent progress and insights with stakeholders. Organizations that approach circular economy initiatives as strategic opportunities rather than compliance requirements stand to gain significant advantages in operational efficiency, cost reduction, brand perception, and environmental impact. Circularity is not a new idea, but as organizations course-correct away from linear models, the circular economy is presenting new opportunities for businesses. As Blenheim Palace's experience demonstrates, organizations that embrace this transition thoughtfully can achieve positive results across the triple bottom line of people, planet, and profit. 'The most surprising aspect of our journey has been discovering that circular systems often outperform linear ones on pure business metrics,' Green says. 'Sustainability is no longer a trade-off against profitability—increasingly, it's becoming a driver of it.'

Sea Resort 2026 Collection
Resort needs to cover a lot of bases, observed Sean Monahan on a walkthrough of Sea's latest offering, and this collection did just that with a selection that ranged from sportswear and workwear separates to velvet party dresses and cargo-pocketed balloon bloomers. The lineup underscored the brand's winning signatures, rather than moved the needle forward, which is a good strategy as the label is growing and expanding across the globe. Just back from a pop-up in Korea, Monahan noted that male K-pop stars are big fans of the sportier pieces from the brand. For resort, these included an embroidered varsity jacket with a striped knit collar, a navy tracksuit with creamy crochet side stripes, and a knit zip-front jacket with a scalloped collar and an inset of figurative lace. Unexpectedly, his co-designer Monica Paolini cut Battenburg lace into a pair or roomy basketball shorts with a matching crop-top of the same material. The same lace was combined with a fine gauge knit to a sexier effect than if it had been paired with something more expected like crepe. Instead of quilting, sampler-style embroidery was used on was used on a rustic, bohemian dress as well as a barn jacket and fluid pants. The '80s touches Paolini has been exploring over the past few seasons were to be found in going-out looks like a jet black velvet dress with slightly puffed sleeves and white bows at the tip of the V-neck, and a corsage on a jacket shown with cropped and side-knitted pants.

Travel Brands Stick With Carbon Capture Firm Despite Layoffs and Setbacks
Carbon capture may be a promising climate solution, but the gap between promise and delivery is growing harder to ignore. Travel companies working with Swiss carbon dioxide removal firm Climeworks told Skift they are sticking with the company, even as it struggles to scale up operations and makes deep job cuts. Climeworks, which built the world's first commercial plant that removes carbon dioxide directly from the air and stores it underground, recently announced it would lay off more than 20% of its workforce. The company cited 'macroeconomic uncertainty and shifting policy priorities.' Climeworks has deals in place with several well-known travel companies, including Lufthansa, SWISS Air, British Airways, and the Adventure Travel Trade Association (ATTA). Swiss Air, part of the Lufthansa Group, was Climeworks' first aviation customer in 2024. The airline has called direct air capture a vital long-term tool for reducing aviation emissions. 'Direct air capture is not only a crucial complementary measure for aviation to achieve its CO₂ targets, but also a highly relevant technology for the future production of Sustainable Aviation Fuel (SAF),' Swiss Air has previously said. Lufthansa signed a multi-year agreement with Climeworks and confirmed to Skift that it has no plans to change course. 'Our partnership with Climeworks is in place since 2024,' a Lufthansa spokesperson said. 'Compensation and innovative processes for filtering CO₂ from the air and storing it form a complementary instrument in the Lufthansa Group's sustainability strategy.' Swiss Air told Skift its agreement runs through 2030 and emphasized that payments are only made once carbon capture credits are delivered. A spokesperson said the company wants to support the scaling of the technology. 'Climeworks is currently the only company in the world that operates Direct Air Capture (DAC) commercially,' it added. British Airways announced a contract with Climeworks in the past for a small amount of carbon removal credits, though it did not respond to Skift's recent request for comment. Previously, the airline said carbon removal was essential to its net-zero plans. 'There is no pathway to net zero for aviation without carbon removals,' Carrie Harris, Director of Sustainability at British Airways, said in September last year. The Adventure Travel Trade Association was one of Climeworks' earlier travel-sector partners. It told Skift it is continuing to work with the company. It supports Climeworks through its 'Tomorrow's Air' program, which offers travelers the option to directly remove CO₂ from the atmosphere. 'A Challenging Time' Climeworks says its carbon capture technology works by sucking co2 out of the air and storing it underground in rocks as stable carbonate minerals. source: climeworks Climeworks, which has raised over $800 million, has captured far less carbon than expected. According to the firm has delivered just 1,100 tonnes of carbon removal so far. That's well below the 380,000 tonnes it has signed deals for. Climeworks did not respond to Skift's request for comment. 'We've always known this journey would be demanding,' CEOs Christoph Gebald and Jan Wurzbacher said in a statement announcing the layoffs. 'Today, we find ourselves navigating a challenging time.' Still, the company is pressing ahead with its Mammoth plant in Iceland, which has a nameplate capacity of 36,000 tonnes of CO₂ per year. But in its first 10 months, it only captured 750 tonnes. Once supply chain emissions were factored in, net removals came to just 105 tonnes, the equivalent of the yearly emissions of about eight Americans. Climeworks' older Orca facility in Iceland was designed for 3,000 tonnes per year, but hasn't hit 1,000 tonnes in any single year since opening in 2021.
