As Europe grapples with record-breaking temperatures, a troubling trend is emerging on social media: influencers are encouraging people to forgo sunscreen, citing unfounded claims that it contributes to skin cancer. Experts are sounding the alarm, emphasising that the evidence overwhelmingly supports the protective benefits of sunscreen against harmful UV rays.
The Rise of Misconceptions
Amidst soaring temperatures, a wave of misinformation has swept across various social media platforms, with influencers propagating the notion that sunscreen is more harmful than beneficial. One viral claim suggests that while sunlight helps the body produce Vitamin D, the chemicals in sunscreen are toxic and increase cancer risk. “Even if you wash your face, sunscreen stays on your skin and increases your chances of getting cancer,” stated one user, echoing the sentiments of many who are misled by these assertions.
However, experts firmly rebut these claims. John Dombrowski, a cosmetic chemist based in the United States, explained that correlation does not equal causation. The increase in skin cancer rates over the decades cannot be directly linked to the rise in sunscreen use since the 1940s. Instead, he pointed to other factors, including a growing and ageing population, which naturally raises the incidence of cancer.
Understanding the Facts
Data from Cancer Research UK indicates that melanoma rates in the UK have surged more than 164 per cent since the early 1990s, with a 26 per cent increase in the last ten years alone. This rise is attributed to a combination of heightened awareness, improved detection methods, and demographic shifts rather than the use of sunscreen.
Anthony Young, a professor at King’s College London, highlighted a crucial point: many people do not apply sunscreen adequately. “They think they’re protected, but they’re not using enough product,” he noted. The NHS recommends that adults apply between six to eight teaspoons of sunscreen to cover all exposed skin effectively. It should be applied 30 minutes before sun exposure and reapplied every two hours, especially after swimming or sweating.
The Role of Regulation
Concerns about sunscreen ingredients have also been amplified by influencers, some of whom label them as “toxic.” Yet, as Dombrowski pointed out, everything is made up of chemicals, including the air we breathe. Sunscreens are heavily regulated in both the UK and the US, with rigorous safety and efficacy standards in place. In the UK, sunscreen products are classified as cosmetics, while in the US, they are treated as over-the-counter drugs, requiring extensive testing before reaching consumers.
The Impact of Social Media Misinformation
Despite TikTok’s efforts to combat misleading content—such as banning the hashtag #antispf since 2025—misinformation continues to circulate. This has raised concerns about the impact of social media on public health behaviours. TikTok has introduced a clinician-creator network in the UK to promote accurate health information, featuring NHS-qualified professionals with significant followings to counteract harmful narratives.
In light of the ongoing heatwave, it is essential that individuals remain vigilant about their sun protection strategies. Anyone noticing unusual skin changes should consult a healthcare professional promptly.
Why it Matters
The current climate crisis, combined with a surge in misinformation, poses a significant threat to public health. As temperatures rise, the risk of UV exposure and skin cancer becomes more pressing. Educating the public on the importance of sunscreen and dispelling myths is crucial for preventing unnecessary health risks. As misinformation spreads, the role of trusted sources and expert voices is more vital than ever in guiding individuals towards making informed decisions for their well-being.
