Does your idea of the perfect vacation center around days spent at the beach? If so, we assume ahigh-coverage sunscreen is an essential part of your beachside beauty routine. That being said, the face sunscreen you use in your daily beauty routine isn't/shouldn't be the same one you bring to Hawaii. The reason? The chemicals in your SPF can rinse off and affect the ecosystems where you swim. That’s why Hawaii became the first state in the U.S. to ban the sale of sunscreen containing the coral-harming chemicals oxybenzone and octinoxate in 2018. Since then, reef-safe sunscreens have become increasingly popular, with seemingly endless brands entering the space.

With so many reef-friendly sunscreens available, it can be hard to know which ones work the best (for you and the environment, that is). To save you from sifting through thousands of reviews, we tested the 24 most popular reef-safe sunscreens. We paid attention to everything from texture and residual cast to water resistance and fragrance. In doing so, we narrowed down the best reef- safe sunscreens for both people and corals.

What We Love: Since it’s developed for kids, this sunscreen is incredibly gentle. 

What We Don't Love: Because this isn’t noncomedogenic, it can clog pores.

The Pipette Mineral Sunscreen outperformed the competition with its ultra-gentle, fragrance-free formula that quickly sinks into skin, doesn’t leave a white cast, and doesn’t transfer onto clothes. “This sunscreen applies very smoothly because of the consistency, and it’s easy to blend into the skin,” our tester shares. “It feels very lightweight on my skin, and there’s absolutely no white cast upon application, nor any pilling.” In addition to sinking seamlessly into skin, we found that this reef-safe sunscreen left skin looking semi-matte without making it feel dry. 

While the SPF isn’t marketed as being water resistant, we found that when splashed with water, it doesn’t run. Still, per the American Academy of Dermatology’s sunscreen guidelines, it’s best to reapply after taking a dip to ensure you’re fully protected for hours to come. Just be aware that it isn’t noncomedogenic, so there is a small possibility that it can clog pores even though it feels nearly weightless.

Type: Mineral | SPF Level: 50 | Water-Resistant: Yes | Active Ingredients: Zinc oxide, squalane, glycerin | Size: 4 oz 

What We Love: It absorbs quickly into the skin without leaving a white cast. 

What We Don't Love: It gets a bit sticky once wet, and it has a strong lemony scent.

Hello Bello Mineral SPF 50+ Sunscreen is another product formulated for children that adults can most definitely benefit from. In addition to being dermatologist tested, clinically tested, and hypoallergenic, this sunscreen has a fabulous consistency that sinks quickly and fully into skin. “It doesn’t feel greasy or overly thick and doesn't leave a white cast on my skin,” shares our tester. While it initially glides onto skin, we found that it does become a bit sticky when wet, but that feeling subsides pretty quickly.

One thing to keep in mind: This SPF is formulated without synthetic fragrances but it definitely has a scent. “This sunscreen has a strong, lemony scent. It's not terribly overwhelming, but it is fairly strong,” our tester admits. “It would be nice if the manufacturer forewarned shoppers on the tube that it’s scented.”

Type: Mineral | SPF Level: 50 | Water-Resistant: Yes, up to 80 minutes | Active Ingredients: Zinc oxide, oat oil | Size: 3 oz 

What We Love: A little bit of this soothing sunscreen goes a long way. 

What We Don't Love: The very wet consistency could be a recipe for a mess.

Biossance Squalane + Zinc Sheer Mineral Sunscreen has a very thin texture—so much so that it’s quite runny and takes pretty much zero effort to squeeze out of the tube. The consistency, while a potential leaking/mess hazard, is what makes this sunscreen absorb so well into skin. Even when our tester used a tablespoon of the SPF (instead of the recommended teaspoon), she found that there was no white cast. “I’m very impressed with its ability to absorb into my skin,” she admits.

The absorbability and lack of white cast aren’t the only reasons this sunscreen stands out: Made with water lily and sugarcane-derived squalane, it also deeply hydrates skin and provides a cooling effect, so it can double as post-sun care if you spend too much time soaking up the rays or forget to reapply.

Type: Mineral | SPF Level: 30 | Water-Resistant: No | Active Ingredients: Zinc oxide, ecotin, butterfly ginger extract | Size: 1.7 oz 

What We Love: This body SPF is easy to travel with given its TSA-friendly size. 

What We Don't Love: The light orange scent may not be for everyone.

In our testing, we found Suntegrity Skincare Natural Mineral Body Sunscreen to work best for full-body protection because of its mineral-based formula that spreads like a dream, and the convenient, travel-friendly packaging. “This sunscreen blends nicely into my skin—it’s not dry, nor oily—it feels so smooth that I can’t even tell I'm wearing sunscreen,” our tester shares.

In addition to being super comfortable, we found that this SPF, while not marketed as water-resistant, does maintain its coverage in the presence of water. “This sunscreen seems to repel the water, making it roll off of my skin,” our tester adds, noting that spritzing her SPF-covered skin didn’t cause the product to run or drip.

Type: Mineral | SPF Level: 30 | Water-Resistant: No | Active Ingredients: Zinc oxide, aloe leaf juice | Size: 3 oz 

What We Love: It absorbs quickly and dries down for a smooth, silky, hydrated finish. 

What We Don't Love: It smells a bit like rubber.

The Blue Lizard Sensitive Mineral Sunscreen with Zinc Oxide 50+ is beloved for its fast-absorbing formula that leaves skin feeling hydrated and smooth. “It absorbs very quickly with minimal rubbing on my end,” our tester says. “It honestly took less time than some of my regular lotions.”

In addition to absorbing quickly, this sunscreen, which is infused with castor oil and vitamin E, doesn’t leave a white cast behind. Instead, it makes skin look (and feel) dewy and hydrated. “It was almost like a body oil feel and effect, but not in a bad way,” our tester explains. What’s more, we found that the lightweight lotion stands its ground against water. The only thing that could make this SPF better, according to our tester, is if it had a more delightful scent.

Type: Mineral | SPF Level: 50+ | Water-Resistant: Yes, up to 80 minutes | Active Ingredients: Titanium dioxide, zinc oxide, vitamin E | Size: 5 oz

What We Love: It’s formulated for kids, so you know it's on the gentler side.

What We Don't Love: It feels a bit sticky, and it's not water-resistant. 

California Baby Super Sensitive SPF 30 Lotion is a fan favorite for children and adults alike. According to our tester, the formula, which is infused with organic and sustainably grown ingredients, blends in easily despite feeling a bit sticky fresh out of the tube. While it doesn’t dry down for an unnoticeable feel, she says that the creamy paste feels similar to applying a heavy moisturizer, so it’s not distracting or uncomfortable. Instead, it makes skin feel shielded. 

That said, the formula doesn’t fully hold its ground in the presence of water. While it doesn’t drip and run, our tester found that, once wet, it does feel more slippery and transfer more.

Type: Mineral | SPF Level: 30 | Water-Resistant: No | Active Ingredients: Titanium dioxide, coconut oil, squalane | Size: 1.8 oz

What We Love: The formula is very smooth, which makes it spread easily.

What We Don't Love: It’s not water-resistant despite claiming to be.

Reef Repair Reef Safe Sunscreen SPF 30+ might not look like the highest quality SPF, but inside the tube you’ll find a lighter-weight reef-safe sunscreen that feels considerably better than most of its competitors. “The consistency is really smooth—it spreads easily compared to other reef-safe sunscreens I've tried and absorbs almost immediately without a white cast,” our tester says.

On the downside, this SPF smells…different. “It smells a little like a plastic beach ball—but only if you get really close to the skin,” our tester clarifies. “I imagine if I really lathered my whole body the scent might be slightly stronger and could potentially be unpleasant, but that's just a conjecture.”

Type: Mineral | SPF Level: 30+ | Water-Resistant: Yes, up to 80 minutes  | Active Ingredients: Zinc oxide, raspberry seed and coconut oils | Size: 1.7 oz

What We Love: It blends in effortlessly, absorbs quickly, and feels comfortable on the skin. 

What We Don't Love: It comes out of the tube a bit chalky.

Maui Naturals Surfer Honey All Natural Sunscreen first caught our attention due to its retro packaging, but it retained interest when we realized just how well it works. “This sunscreen applies really smoothly, and the texture is pleasant to rub across my skin,” our tester says—though she points out that it feels a bit chalky and looks grayish-purple out of the tube. “I’m impressed with how easily this sunscreen spreads,” she adds. “This absorbs quite quickly and doesn’t require much rubbing to get it to lose its white cast.”

Best of all, this water-resistant, reef-safe sunscreen, which smells like an orange creamsicle, lives up to its claims. “I was impressed with how water-resistant it is,” our tester marvels. “When I rubbed the water around on my arm, it did not seem to dissolve the sunscreen and rather just made the water bead on top of it.”

Type: Mineral | SPF Level: 30+ | Water-Resistant: Yes, up to 80 minutes  | Active Ingredients: Zinc oxide, aloe leave juice | Size: 3 oz

What We Love: This tropical-scented sunscreen will transport you to an island with every application. 

What We Don't Love: The bottle design is prone to leaks.

If you actually prefer a scented sunscreen, you’ll swoon over Hawaiian Tropic Mineral Skin Nourishing Milk SPF 50. Beyond its refreshing coconut scent, which our tester says smells like a pina colada, this SPF has a very thin consistency, which makes it easy to apply. 

“It quickly absorbs into my skin without need for frequent rubbing,” our tester says. Though, she notes that it seems to get darker as it fully dries down, so while it doesn’t initially have a white cast, after 15 minutes, she noticed a slight residue.

Type: Mineral | SPF Level: 50 | Water-Resistant: Yes, up to 80 minutes  | Active Ingredients: Titanium dioxide, papaya fruit extract | Size: 3 oz

What We Love: It’s lightweight, creamy and doesn’t leave a white cast.

What We Don't Love: The stick is quite small and may not last very long.

Not trying to toss a bottle of reef-safe SPF into your bag only for it to leak all over the place? Opt for a stick. Namely, MDSolarSciences Mineral Sunscreen Stick SPF 40. Formulated to be lightweight and creamy, the stick SPF applies beautifully, absorbs quickly, and doesn’t leave a white cast—not even on darker skin tones. 

“When first applying the product, I was worried because it looked like it would leave a white cast, but once I rubbed it in, it absorbed completely and actually left my skin with a nice glowy look,” our tester reveals, noting that most mineral SPFs, in contrast, give off a ghostly look on her darker skin. While the small format makes it easy to toss in any purse for touch-ups, we find that if you apply it regularly, it probably won’t last you more than a month or two.

What to Keep in Mind

  • Scent: Generally speaking, scented skin care products are more likely to cause irritation than their fragrance-free counterparts. When it comes to reef-safe SPF, it’s important to remember that just because a product might say that it’s made without synthetic fragrances doesn’t mean that it won’t have a scent. That’s because some products use essential oils, which in and of themselves have a fragrance. With this in mind, when shopping for reef-safe sunscreen look for fragrance-free and/or unscented formulas, as opposed to eagle-eyeing in on synthetic scents (or a lack thereof).
  • SPF Level: According to the American Academy of Dermatology, using an SPF of level 30 or higher is key to adequately protecting skin against the harmful effects of the sun’s rays. Even with the right SPF level, it’s important to remember that no SPF (not even SPF 100) can fully block out UVB exposure. As such, you should seek shade whenever you can to shield your skin from excessive exposure, and remember to reapply every two hours.
  • Water-Resistance: Even if an SPF claims to be water-resistant, dermatologists recommend reapplying sunscreen after swimming. If you’re just sweating a lot, though, you can probably get away with holding out for the duration of the product’s purposed resistance (which is typically in the 80 minute range). Just because a sunscreen is reef-safe doesn’t make it inherently water-resistant.

Your Questions, Answered

What makes sunscreen reef-safe?

While oxybenzone and octinoxate are popular chemical sunscreen ingredients, they’ve been shown to cause coral bleaching which can obliterate reefs. “When we apply sunscreens containing these ingredients and then swim in waters where there is coral, the sunscreen gets into the water and poisons the coral,” says board-certified dermatologist Dr. Sumayah Jamal of Schweiger Dermatology Group in NYC. Wearing sunscreens without either oxybenzone or octinoxate can help mitigate the problem and help coral reefs thrive.

The easiest way to ensure you’re using reef-safe sunscreen is to choose a formula that’s clearly marketed as such. “Sunscreens with the Protect Land + Sea Certification Seal are considered safe,” Dr. Jamal says.

Is mineral sunscreen reef-safe?

Usually, yes. In fact, mineral sunscreen is often thought to be synonymous with reef-safe SPF. That said, Dr. Jamal says it depends on the exact formulation. “Mineral sunscreens, such as titanium dioxide and zinc oxide, are generally not toxic to coral, however, when they are formulated as nanoparticles they can still damage coral,” she explains. “Micronized or non-nanoparticle mineral screens are best for reef safety.”

Does reef-safe sunscreen affect skin differently?

Reef-safe sunscreen (a.k.a. mineral SPF) operates differently than traditional chemical sunscreen. “Mineral sunscreens work by staying on top of the skin and blocking UV rays by reflecting them to keep from entering the surface,” Dr. Henry says. “By shielding the epidermis from UV absorption, mineral sunscreens are also effective forms of sun protection. They reflect light and do not convert it to heat like chemical sunscreens, thus making them ideal for sensitive skin.”
