On TikTok, the anti-sunscreen brigade goes robust, with influencers spreading misinformation and preying on fears. Their uneducated two cents sound somewhat like this: “Sunscreen causes most cancers;” “Your pores and skin wants vitamin D from the solar;” and “You may get ample SPF from a well-balanced food plan.” That innately flawed line of considering is straight-up unsuitable, and—understandably—makes dermatologists, significantly those that are on the frontlines of skin-care social media themselves, irate.
Whereas in an ideal world, social media can be absent of such misinformation, that is not actuality. What may be is equipping your self with information to guard your self and scroll safely.
Dermatologists take concern with sunscreen misinformation on-line
“As a dermatologist, I’m more and more annoyed and saddened by these conspiracy theories,” says Lindsey Zubritsky, MD, a board-certified dermatologist with greater than 500,000 followers on Instagram and greater than 1 million on TikTok.
In August, Dr. Zubritsky posted a video titled “Details About Tanning That Will Alter Your Mind Chemistry” wherein she defined that any kind of solar tan is proof of DNA harm and that our pores and skin solely will get darker when it’s uncovered to UV rays as a result of it’s attempting to guard itself towards additional hurt. Whereas a lot of the feedback on the video supported her knowledgeable opinion, one particular person really mentioned, “The solar actually offers life to every thing on Earth. Many sunscreens have been confirmed to trigger most cancers.”
However as any dermatologist—together with Dr. Zubritsky—will let you know, that is categorically false. Particularly as a result of not sporting sunscreen places you at a a lot increased threat for growing most cancers than any SPF product in the marketplace ever may (extra on that under).
“I see, diagnose, and deal with pores and skin cancers—together with lethal melanomas—every day,” says Dr. Zubritsky. She provides that nearly each single pores and skin most cancers she’s identified has been straight associated to solar publicity, and empirical information parallels these anecdotal figures.

One in 5 People will develop pores and skin most cancers of their lifetime, and research have proven that roughly 86 p.c of melanomas might be attributed to solar publicity2, significantly the ultraviolet radiation from the solar. That quantity jumps as much as 90 p.c when speaking about nonmelanoma pores and skin cancers, that are extra frequent. (For reference, genetic predisposition, radiation, and smoking are just a few of the causes that make up that different 10 to 14 p.c, says Dr. Zubritzky.)
Mamina Turegano, MD, a board-certified dermatologist with greater than 300,000 followers on Instagram and upwards of 1 million on TikTok, equally takes concern with sunscreen conspiracy theories and misinformation on-line. “It’s very regarding as a result of the people who find themselves saying this stuff haven’t got expertise treating sufferers or treating pores and skin most cancers,” says Dr. Turegano. “They don’t seem to be seeing the ramifications of not sporting sunscreen. When individuals who aren’t certified say that sunscreen is ‘inflicting most cancers’ …they’re inflicting extra hurt.”
Like Dr. Zubritsky, Dr. Turegano has taken it upon herself to fight the sunscreen misinformation floating round on social media. In Could, she re-posted a video she’d made in 2022 wherein she urged individuals to not be afraid of SPF. She additionally inspired her followers to take further solar protecting measures, like sporting a big hat and utilizing sun shades. And somebody nonetheless commented, “Some sunscreens are dangerous for you as nicely. Watch out what you utilize.”Sadly, this isn’t the one tidbit of misinformation on the web. There are just a few of those conspiracy theories within the zeitgeist—so let’s unpack them with three board-certified dermatologists.
SPF conspiracy theories that dermatologists are begging you to cease believing (and what’s really true)
1. Chemical SPF causes most cancers
SPF—the primary ingredient in sunscreen—prevents most cancers. It’s actually so simple as that. Massive our bodies of scientific analysis1 have confirmed that it protects our pores and skin from the solar’s dangerous, cancer-causing UV rays, and definitively doesn’t trigger most cancers.
“For many who declare that the chemical compounds in sunscreen itself are enjoying a task in inflicting pores and skin cancers, I’d counter that there isn’t any medical proof that sunscreen causes most cancers,” says Deanne Mraz Robinson, MD, board-certified dermatologist and assistant scientific professor of dermatology at Yale.
So why are influencers saying that it does? For starters, there’s the widespread villification of chemical compounds. Over the previous decade, the rise of fresh magnificence has induced individuals to query the well being impacts of sure “poisonous” components, and that mindset has made its means into the sunscreen dialog.
A misguided total worry of chemical compounds has made some customers hesitant to make use of chemical sunscreen formulation (versus mineral sunscreens) that include blockers like avobenzone, homosalate, octinoxate, and oxybenzone that sink into your pores and skin to soak up ultraviolet rays and convert them to warmth. When a small 2019 research3 performed by the Meals and Drug Administration (FDA) on 24 members discovered that as these components sink into our pores and skin, additionally they sink into our bloodstream at ranges increased than the brink the company set again in 2016, it understandably raised some alarm bells. Nevertheless, the company was fast to say, “These outcomes don’t imply that the components are unsafe,” and urged individuals to proceed to put on sunscreen.
“Persons are petrified of the phrase ‘chemical,’ however there’s not sufficient proof for the FDA or dermatologists to say you could’t use chemical sunscreens now,” says Dr. Turegano.
“There is no such thing as a medical proof that sunscreen causes most cancers.”—Deanne Mraz Robinson, MD
Moreover, a latest (voluntary) recall of sunscreens containing a cancer-causing contaminant referred to as benzene helped fire up misinformation. Importantly, although, “this contaminant is simply that: a contaminant. It was not, and isn’t, meant to be in sunscreens,” says Dr. Zubritsky.
In different phrases, nobody is placing benzene in sunscreen—it is one thing that may develop in a method throughout manufacturing (FWIW, it’s additionally been discovered as a contaminant in different magnificence and grooming merchandise, together with deodorants, dry shampoos, and foot sprays). What’s extra, benzene has solely been linked to leukemia in excessive ranges of publicity—which might require a complete lot greater than the hint quantities that have been discovered within the recalled sunscreen. And, oh yeah: The contaminated sunscreens have been taken off the market as quickly because the benzene was found.
And but, anti-SPF wellness influencers have taken this info at face worth, glossed over the details, and wrongly concluded that “sunscreen causes most cancers” with out studying the positive print. As Dr. Turegano places it, they’re basically “throwing the newborn out with the bathwater”—and, satirically, placing themselves at the next threat of growing most cancers by braving the solar unprotected.
Additionally? Should you are a type of individuals who feels fear on the utterance of the phrase “chemical,” no matter it not being linked to cancer-causing components in SPF, that’s okay—you have got different solar protecting choices. “If anybody is anxious with chemical-based SPFs, I’d recommend that they swap over to a mineral SPF,” says Dr. Mraz Robinson. A majority of these formulation use mineral solar blockers like zinc oxide and titanium dioxide, which sit on prime of the pores and skin (as an alternative of being absorbed into it) and replicate UV rays, so there is not any concern about components making their means into your bloodstream.
2. Direct daylight is sweet in your pores and skin.
Permit us to be unequivocal: There may be no quantity of direct daylight that’s good in your pores and skin. “In medication, there’s not quite a bit we will say 100%—however we all know that the solar at all times will increase threat of pores and skin most cancers and causes DNA harm,” says Dr. Turegano.
“Tanning is our physique’s response to this harm—it creates extra melanin as a protecting measure to scale back additional harm,” Dr. Zubritsky provides. Although there’s actually one thing to be mentioned in regards to the confidence you get whenever you’re sun-kissed, dermatologists are emphatic that sun-soaking is simply not well worth the threat.
3. Sunscreen blocks your pores and skin from getting vitamin D.
“The reality is that so as to get ample vitamin D by means of daylight, we solely want a couple of minutes of publicity to the solar just a few occasions every week,” says Dr. Zubritsky. She provides that there are a number of the explanation why sunscreen doesn’t result in a vitamin D deficiency.
“First, nobody applies sunscreen precisely as directed—even dermatologists,” she says, nodding to the truth that you want a whole shot-glass value of SPF to cowl your entire physique, and only a few persons are really utilizing that a lot or re-applying on the really helpful two hours. “Second, sunscreen just isn’t 100% protecting towards UV rays. An SPF of 30 solely blocks round 97 p.c of UV rays and permits about 3 p.c to penetrate our pores and skin.” Put merely, our pores and skin continues to be in a position to soak up vitamin D when sporting sunscreen.
That mentioned, for those who are vitamin D poor—or really feel such as you want an additional enhance—there are methods to introduce the nutrient into your physique with out baking within the solar. “The vast majority of the inhabitants can keep wholesome vitamin D ranges with a balanced food plan of vitamin D-fortified meals [like egg yolks and salmon] in addition to taking dietary dietary supplements,” Dr. Mraz Robinson.
4. You may get ample solar safety out of your food plan.
That is most likely the trickiest SPF conspiracy principle as a result of it virtually is sensible. It’s true that there are meals that enhance your inner SPF5, like tomatoes, candy potatoes, and spinach. What’s unfaithful, nevertheless, is that they supply sufficient solar safety in and of themselves. As an illustration, there are of us who declare that consuming raspberry seed oil is basically the identical as sporting sunscreen as a result of the liquid is a good antioxidant.
Whereas it’s true that raspberry seed oil gives some solar safety4, no meals can take the place of a correct sunscreen. “None of this stuff are going to be environment friendly sufficient to interchange sunscreen,” emphasizes Dr. Turegano. “We don’t have standardized numbers on this, so we will’t make suggestions on consuming a specific amount. Even when there have been, although, it wouldn’t be sufficient.”
The way to discern between bona fide SPF recommendation and conspiracies
On the threat of oversimplifying, if an influencer is saying that you just don’t want solar safety, that your physique can produce it naturally, or that sunscreen causes most cancers, it’s protected to say that’s a conspiracy principle.
One other good tip for understanding the distinction between the reality and a lie is trusting dermatologists and never unaccredited skinfluencers—regardless of how charming they’re. “Should you ever have any questions concerning SPF, converse to your dermatologist,” recommends Dr. Zubritsky. “We spend [so much time] coaching; understanding and studying medical literature and research.”
Should you don’t have entry to a dermatologist, although, there’s nonetheless a wealth of credible details about sunscreen out there on-line. Dr. Turegano and Dr. Zubritsky recommend consulting the American Academy of Dermatology, which has tons of evidence-based, digestible info. Should you’re extra academically inclined, you may additionally think about sifting by means of scientific articles on PubMed, the place you may search for biomedical and life sciences literature written by precise consultants.
And as for me—a well-being journalist who offers the truth is, not pseudoscience—I’ll be telling these so-called “skinfluencers” to take their misinformed recommendation and shove it the place the solar don’t shine.
