As holiday season approaches, a study warns against the spread of misinformation about sunscreen on the social network TikTok. While the vast majority of videos encourage sun protection during a city stroll or a beach swim, a handful of contentions argue the opposite—that these products would be dangerous for health or unnecessary. If these posts are few, they provoke far more reactions from internet users than others. At times cautious, at times outraged, or, more seriously, tempted to drop these protections from their summer routine.
Nearly 1,000 videos published on the platform in 2024 about sunscreen were analyzed by a group of researchers, with the Washington Post taking up the story on Saturday, June 20. About 87% of them promoted it, nearly a third recalled the importance of applying it “a sufficient amount”, 42 videos were shared between recommendations and criticisms, and 16 videos prohibited its use. And it was precisely this last category of content that received “many more comments, likes and shares”, note the study’s authors.
False Advice, Real Lies
The most viral TikTok messages claim that sunscreens would be toxic, contain carcinogenic substances, or prevent enjoying the sun’s benefits. Others say it would be better to tan without protection or to use alternatives like beef tallow. “Deceptive and provocative ideas, for example that sunscreen is useless or harmful, incorporate elements of novelty, shock and conspiracy theories that provoke emotions and increase their viral potential”, notes the scientific report.
Fearing the proliferation of these “hoaxes”, health professionals insist in unison that they rest on no scientific basis and that prolonged exposure without protection, which absorbs or reflects ultraviolet rays, greatly increases the risk of skin cancer. In short, “you are harming yourself intentionally”, explains Adam Friedman, professor and head of the dermatology department at George Washington University, who did not participate in the study.
TikTok Calls on Moderators
Experts acknowledge that the sun helps the body produce vitamin D, but that does not justify giving up proper protection. Yet, “some audiences are very attracted to this type of information”, regrets Alessandro Marcon, a researcher at the Health Law Institute of the University of Alberta and co-author of the study.
For its part, TikTok reiterates that its policy bans health misinformation and says it is actively pursuing the implicated content to remove it. The challenge now is to better inform travelers and vacationers, as skin cancers continue to rise.
