A recent study published in PLOS Digital Health has shed light on a concerning trend within social media: content promoting sunscreen misinformation on TikTok tends to generate significantly higher user engagement than evidence-backed advice. Researchers analyzed 971 videos related to sunscreen and found that while the vast majority of creators advocate for its use, a small subset of videos—just 16 out of the sample size—actively discouraged sunscreen usage or questioned its safety. Despite their scarcity, these posts often receive disproportionate amounts of likes, comments, and shares compared to their fact-based counterparts, highlighting an algorithmic tendency to prioritize provocative, contrarian content over standard medical guidance.
Experts suggest this phenomenon is a byproduct of how social media platforms function, noting that inflammatory claims are inherently more likely to trigger discussion and debate. Paul Banwell, a U.K.-based cosmetic surgeon and skin health expert, notes that when individuals claim sunscreen is toxic or unnecessary, they are effectively challenging long-accepted medical advice. This creates a “clickbait” effect where misinformation thrives because it strikes a provocative tone, often overshadowing the drier, more repetitive health messaging provided by dermatologists and medical organizations. Consequently, even a small volume of misleading information can gain enough visibility to confuse the public and sow doubt regarding established safety standards.
The impact of this misinformation is of particular concern to health professionals, as the potential consequences of skipping sun protection are severe. Banwell emphasizes that the framing of sunscreen in online discourse is often too narrow, focusing predominantly on aesthetic benefits such as anti-aging, wrinkle prevention, and the mitigation of pigmentation. While these are valid reasons to use sunscreen, they often fail to communicate the primary medical imperative: the prevention of skin cancer. Because younger audiences often view sunscreen purely as a beauty product, they may erroneously conclude that because they aren’t worried about wrinkles, they do not need sun protection.
Addressing this knowledge gap requires a shift in how sun-safe habits are promoted. Banwell advocates for a more comprehensive narrative that treats sun protection as a foundational pillar of general health rather than a niche beauty trend. By emphasizing that sunscreen is the primary defense against long-term ultraviolet (UV) damage—which is a leading cause of skin cancer—influencers and health experts can provide a more compelling, life-saving reason for users to incorporate it into their daily routines. The goal is to move the conversation from “avoiding aging” to “securing lifelong skin health,” a shift that could better resonate with the younger demographics that frequent TikTok.
The study underscores a critical need for influencers, brands, and medical professionals to step up their efforts in providing accessible and engaging health education. Because young people are increasingly turning to TikTok as a primary source for health tips, creators hold significant influence—and with that influence comes a professional responsibility. Banwell argues that sun safety should be instilled as a lifelong habit, similar to brushing one’s teeth, starting from childhood to mitigate the cumulative effects of sun exposure. By making evidence-based routines more visible and attractive, the medical community can begin to counteract the influence of viral myths that discourage necessary health practices.
Ultimately, the findings serve as a reminder that the digital age requires a higher degree of media literacy, particularly regarding health advice. TikTok’s spokesperson has stated that the platform prohibits health-related misinformation, yet the study suggests that the moderation of nuanced medical claims remains a challenge. Until platforms can effectively distinguish between healthy skepticism and dangerous medical myths, consumers must remain vigilant. Sunscreen, as experts point out, is not about living in fear of the outdoors; it is about enjoying the sun safely. By separating fact from fiction and prioritizing long-term health over viral vanity, the public can better protect themselves against the very real risks of skin cancer.
