…However not simply any sunscreen.
By now, you’ve probably heard that many sunscreens include many chemical compounds which might be poisonous to oceanic ecosystems, particularly coral reefs. Scientists have been sounding this alarm since 2008.2
And but, we will’t simply cease carrying sunscreen. Everyone knows it’s essential to guard us from the solar’s dangerous UV rays that may trigger sunburns, pores and skin most cancers and different kinds of pores and skin injury. But when the chemical compounds in sure sunscreens are hurting marine ecosystems, the query additionally begs to be requested: How protected is that this sunscreen for people?

What Do ‘Reef Protected’ and ‘Reef Pleasant’ Labels Imply?
TL;DR: “Reef protected” and “reef pleasant” language on sunscreen merchandise could be one other instance of greenwashing — a misleading advertising and marketing tactic that manufacturers use to come back throughout as extra eco-friendly.
The meant which means of those labels is self-explanatory: “This product shouldn’t be dangerous to coral reefs.” The issue is that there’s no regulation with regards to reef-safe labels.
“There’s no universally acknowledged definition of what’s ‘reef protected.’ So what reef protected means to me versus what it’d imply to a Fortune 500 firm, or a advertising and marketing firm, may be very completely different,” mentioned Autumn Blum, formulator and CEO at Stream2Sea.
Usually, what a sunscreen firm is saying with a “reef protected” label is that the product doesn’t include oxybenzone or octinoxate — two substances which have been acknowledged as dangerous to each people and marine life. However analysis reveals these aren’t the one dangerous chemical compounds present in sunscreens.
“As a substitute of utilizing oxybenzone and octinoxate, they merely changed it with avobenzone and octocrylene, which are actually being proven to be equally or, in some circumstances, much more dangerous than the preliminary,” mentioned Blum. “The absence of two poisonous chemical compounds doesn’t make it ‘protected,’ proper? However who’s it to resolve that?”
Sunscreen’s Unfavorable Impact On Aquatic Ecosystems
Scientists discovered that many private care merchandise, like sunscreen, negatively affect marine techniques again in 2008 after a coral bleaching occasion.3 A number of locations, together with Hawaii and Key West, Florida, have banned sure reef-harming sunscreens, however new information reveals that it’s nonetheless a really actual concern.
As an illustration, greater than 90% of the Nice Barrier Reef — that’s 654 reefs — skilled some form of bleaching throughout the 2021-2022 Australian summer season. Whereas bleaching isn’t solely attributable to dangerous chemical compounds — local weather change and ocean warming play the largest roles — they will actually worsen the difficulty. And researchers are actively learning extra environmental impacts of sunscreen substances, with outcomes anticipated to be launched someday in 2022.4
Coral reefs are a significant a part of the ocean ecosystem and an enormous draw for tourism, so it is sensible that “reef pleasant” is the time period sunscreen corporations are going with. However corals aren’t the one species in danger. Sunscreen chemical compounds can even negatively have an effect on dolphins, fish, inexperienced algae, mussels and sea urchins.5

Whereas most scientists are researching the adverse affect on marine life, newer research have additionally proven that energetic chemical compounds in sunscreen are additionally harming freshwater ecosystems like lakes and rivers.6
And aquatic species aren’t the one ones in danger.
“I feel there’s a actual concern with human well being as effectively,” mentioned Rebecca Hamilton, Co-CEO of Badger, an natural skincare firm.
How Sunscreen Can Be Poisonous for People
TL;DR: Analysis reveals that sunscreens include poisonous chemical compounds which have been linked to pores and skin reactions in addition to cancers and beginning and reproductive defects.
Sunscreen is a double-edged sword. It’s filled with substances confirmed to guard our pores and skin from damaging UV rays, however at what price? The desk beneath outlines a few of the human considerations for eight widespread sunscreen substances authorised by the U.S. Meals and Drug Administration (FDA).
Widespread Sunscreen Ingredient | FDA Categorized as Protected and Efficient? | Potential Dangers for People* |
Oxybenzone | No | Allergic pores and skin reactions; breast most cancers; hormonal disruptor; irregular beginning patterns; endometriosis |
Octinoxate | No | Hormonal disruptor affecting the metabolic system, thyroid, androgen and progesterone signaling; allergic reactions |
Homosalate | No | Hormonal disruptor; produces poisonous breakdown byproducts over time |
Octisalate | No | Allergic contact dermatitis; potential hormonal disruptor |
Octocrylene | No | Excessive charges of pores and skin allergy symptoms; usually contaminated with carcinogen benzophenone |
Avobenzone | No | Hormonal disruptor; allergic reactions |
Titanium dioxide | Sure | Presumably carcinogenic if inhaled (spray and powder merchandise needs to be prevented) |
Zinc Oxide | Sure | Presumably carcinogenic if inhaled (spray and powder merchandise needs to be prevented) |

Sunscreen Chemical compounds Seep Into the Bloodstream
Research way back to 2008 have discovered traces of sunscreen substances in breast milk and urine samples.7,8 However a 2019 examine printed by the FDA revealed that sunscreen chemical compounds seep into our bloodstreams and may be detected on our pores and skin and in our blood weeks after we apply it.9
When that 2019 examine was printed, the FDA solely labeled two sunscreen substances as “protected and efficient” — titanium dioxide and zinc oxide. As for the others, the administration mentioned the presence of those substances in our blood shouldn’t be essentially a well being hazard, however that it’s positively a excessive sufficient quantity to warrant “additional testing.”10
As Blum factors out, we’re nonetheless ready on that analysis.
“[The FDA] declared that solely titanium dioxide and zinc oxide are typically acknowledged as protected and efficient for people, which is a good begin, proper? So all of these different substances that we’re seeing which might be nonetheless allowed in our sunscreens, the FDA says, ‘We’re not so positive about that, are you able to give us extra information?’ And the [sunscreen] business nonetheless has not given extra information,” Blum instructed EcoWatch.
The FDA did suggest additional information and stricter rules on sunscreen corporations after that 2019 examine was printed. Nevertheless, the 2020 Coronavirus Support, Aid and Financial Safety (CARES) Act reformed the best way the FDA regulates sure over-the-counter merchandise, together with sunscreen, and basically put these plans on maintain.11
Most cancers-Inflicting Chemical compounds Present in Sunscreen
A newer examine from 2021 discovered that the sunscreen ingredient octocrylene degrades into benzophenone, which is a compound suspected to trigger most cancers and intrude with the physique’s hormones.12
That very same yr, we noticed recollects for 5 Johnson & Johnson aerosol sunscreen merchandise that contained the carcinogen benzene.13 The recollects included sure merchandise from many prime manufacturers, together with Coppertone, Banana Boat, Neutrogena and Aveeno.14
Sunscreen Considerations for Pregnant and Nursing Girls
In the meantime, oxybenzone merchandise have been discovered to pose a danger particularly for pregnant and nursing moms.
Research have discovered this chemical within the urine and blood of pregnant ladies in addition to in fetal and umbilical twine blood.15 And girls with medium to excessive ranges of oxybenzone of their urine confirmed a correlation to giving beginning to infants with Hirschsprung’s Illness — a colon situation that makes it tough for infants to go stool.16
Sunscreen Product Information: What To Look For and What To Keep away from
Regardless of the quite a few research which have raised considerations about many of those chemical compounds, nearly all of them are nonetheless FDA-approved sunscreen substances. And sadly, meaning you’ll must put in a bit of additional work to search out merchandise which might be protected for each you and the atmosphere.
“It truly is as much as the buyer to maneuver past what’s on the entrance bundle and flip over the bottle and learn,” Blum mentioned. “It’s important to learn these substances.”
EcoWatch has compiled the next listing of what you need to be avoiding, in response to the EWG and HEL.15,16 Once more, the FDA hasn’t explicitly mentioned any of those sunscreen substances are unsafe, however none of them is classed as “protected and efficient” by the administration.17

It can save you this listing of substances to keep away from for straightforward entry when shopping the sunscreen aisle, however Hamilton suggests an excellent simpler strategy: Simply search for merchandise with fewer, extra pure substances altogether.
“The less complicated the substances, the better it’s to inform,” she mentioned. “As a result of it will get actually sophisticated.”
Beneath are a couple of different merchandise to search for and keep away from.
Keep away from: Sunscreen Sprays
We all know spray sunscreens are well-liked for his or her ease and comfort, however it’s best to keep away from them. Folks utilizing spray sunscreens have a a lot greater danger of sunburn, particularly since most don’t rub the spray in (sure, you’re speculated to).18
However past that, aerosol sunscreens may be damaging to your lungs and to the ecosystems which might be getting drenched by it.
“You’re utilizing all of those chemical substances which have been proven to be dangerous for the atmosphere, and also you’re simply spraying them in all places,” Blum mentioned of aerosol sunscreens. “When you spray it in your physique on a ship, I can scent it 100 yards away. That’s been confirmed.”
In accordance with EWG, the FDA discovered that three of 14 examined sprays wouldn’t meet the administration’s proposed inhalation customary, nevertheless it didn’t reveal which three merchandise failed the take a look at, so it’s finest to only keep away from them altogether.19
Human and environmental hazards apart, Blum additionally factors out that spray sunscreens are a ship proprietor’s worst nightmare, proven to stain and injury vinyl.
Keep away from: Sunscreen Powders
Sunscreen powders, or brush-on sunscreens, have proven effectiveness at stopping UV rays from damaging our cells, however they pose an inhalation menace just like that of spray sunscreens. Particularly for the reason that “protected” sunscreen substances (titanium dioxide and zinc oxide) are harmful in powder kind.
“When titanium is inhaled in a tremendous powder, it behaves in your lungs just like asbestos would. That’s dangerous information — you shouldn’t inhale this stuff,” Blum mentioned.
Keep away from: SPF Above 50+
In case your sunscreen says it has a Solar Safety Issue (SPF) of 100, it’s deceptive.
The FDA tried to ban sunscreen corporations from placing something greater than “SPF 50+” on labels in 2011. Since then, the administration reportedly discovered proof of scientific advantages of sunscreen merchandise as much as SPF 60 and at present recommends 60+ as the utmost labeled worth.20
EWG nonetheless recommends you keep away from merchandise with an SPF label over 50+.

Look For: Mineral Sunscreen
Mineral sunscreens primarily use solely natural substances in addition to the one two sunscreen substances licensed protected and efficient by the FDA. So should you see a mineral sunscreen, it can save you your self the difficulty of getting to recollect all of these lengthy and complicated merchandise that it’s best to keep away from.
Nevertheless, Blum says not all mineral sunscreens are created equal.
“I might solely suggest utilizing a sunscreen product that has non-nano zinc oxide and non-nano titanium dioxide. The rest that’s in there has not been confirmed protected,” she mentioned.
Mineral sunscreens nonetheless need to earn FDA approval for UV effectiveness.
Mineral Vs. Chemical Sunscreen: What’s the Distinction?
“I feel folks will simply need to get familiarized with utilizing a mineral-based sunscreen. It’s a distinct expertise than the chemical sunscreens,” Hamilton instructed EcoWatch. “It requires folks recognizing that, you recognize, to have sunscreen that’s protected for them and protected for the atmosphere, it may be a bit of little bit of a distinct consumer expertise.”
So, what’s so completely different about mineral sunscreens?
Mineral Sunscreens Take Longer to Apply
Chemical sunscreens are straightforward to glob or spray on and rub throughout our our bodies inside seconds, whereas mineral sunscreens require extra time and technique.
“One of the simplest ways to use mineral sunscreen is to take a really small quantity, put it in your face, one other small quantity in your chest, one other small quantity, put it in your shoulders and carry on going,” Blum mentioned. “It’d take an additional minute, perhaps even two to use it correctly. However it’s so effectively value the additional effort [to use] the safer product for you and for the planet.”
Mineral Sunscreens Could Depart a White Solid
Mineral sunscreen principally works by formulating chalky substances into lotion, and that may go away a white sheen or residue on the pores and skin. However Blum and Hamilton each instructed EcoWatch that newer know-how is bettering this problem.
“It’s not fairly just like the previous zinc lifeguard streak in your nostril anymore, nevertheless it’s nonetheless a mineral powder dispersed right into a lotion,” Blum mentioned. “When you tried utilizing a mineral sunscreen 20 years in the past and also you hated it, [know that] know-how has come a good distance.”
Mineral Sunscreens Received’t Break You Out
As a result of they’re filled with zinc oxide, mineral sunscreens are skin-calming and finest for delicate and acne-prone pores and skin.
“With mainstream sunscreens, lots of people will say, ‘I can’t put on sunscreen as a result of it burns my eyes’ or ‘it causes me to interrupt out.’ And usually these are the substances from the chemical compounds,” Blum mentioned.
