As Europe grapples with unprecedented heatwaves, a concerning trend has taken root online: a wave of misinformation suggesting that sunscreen is harmful rather than protective against skin cancer. Influencers and podcasters are advocating for the abandonment of this essential skincare product, but experts are vehemently debunking these claims, reaffirming the vital role sunscreen plays in safeguarding our health.
The Rise of Misinformation
With temperatures soaring, social media has become a breeding ground for dubious assertions concerning sunscreen. One viral claim suggests that while sunlight enhances Vitamin D production—which is believed to combat cancer—sunscreen is filled with harmful chemicals that allegedly increase cancer risks. Another voice in this discourse states, “Even if you wash your face, sunscreen stays on your skin and increases your chances of getting cancer.” However, experts assert that these statements lack scientific backing and are alarmingly misleading.
The hashtag #antispf has made headlines for being banned on TikTok since 2025, yet similar sentiments persist across various platforms, sustaining a conspiracy theory that resurfaces every summer. Central to this theory is a flawed narrative: as sunscreen usage has surged since the 1940s, so too have skin cancer rates. But experts clarify that correlation does not imply causation.
Expert Insights on Skin Cancer Trends
According to Cancer Research UK, the incidence of melanoma—a particularly aggressive form of skin cancer—has escalated by over 164 per cent in the UK since the early 1990s, with a 26 per cent increase in the last decade alone. This surge is attributed to multiple factors, including a growing and ageing population, heightened awareness of melanoma, and advancements in detection technologies.
John Dombrowski, a cosmetic chemist from the United States, remarked, “It’s the perfect example of correlation not equating to causation.” He emphasised that an uptick in cancer cases does not stem from sunscreen but rather from a myriad of societal and environmental changes.
Misapplication and Misunderstanding
Professor Anthony Young, an expert in dermatology at King’s College London, pointed out a critical issue: many people misuse sunscreens. Often, individuals apply insufficient amounts, leading to inadequate protection and a false sense of security. Research indicates that those who regularly use sunscreen can still experience sunburn, not due to the product itself but rather because it hasn’t been applied correctly.
The NHS recommends that adults should use six to eight teaspoons of sunscreen to adequately cover the body. It should be applied generously to all exposed skin 30 minutes before sun exposure and reapplied every two hours, or immediately after swimming or sweating.
The Reality of Sunscreen Regulations
The concern over sunscreen’s chemical constituents fuels the ongoing debate. The Melanoma Research Alliance reported that 59 per cent of Americans express anxiety about the ingredients in sunscreen. Yet, Dombrowski reassures that the presence of chemicals does not inherently render a product dangerous. “Everything with mass is a chemical. Air, your chair, your blankets—it’s all a chemical,” he explained.
Sunscreen is regulated differently across various countries. In the United States, it is classified as an over-the-counter drug overseen by the Food and Drug Administration (FDA), requiring rigorous testing before it can reach consumers. In the UK, sunscreens generally fall under cosmetic regulations, which also mandate stringent safety and efficacy tests.
Addressing Misinformation on Social Media
TikTok has not commented specifically on the misinformation surrounding sunscreen, but it has reiterated its commitment to community guidelines that prohibit misleading content. The platform recently established a clinician-creator network in the UK, featuring NHS-qualified professionals to help counteract harmful narratives and educate the public on health matters.
Despite the steps taken by social media platforms, the barrage of misleading information persists. It remains crucial for individuals to consult reputable sources, especially regarding health-related topics.
For anyone observing unusual skin changes, Cancer Research UK offers resources for identifying concerning symptoms, encouraging individuals to consult their GP for advice.
Why it Matters
The propagation of false claims about sunscreen during a health crisis not only endangers individual well-being but also undermines public health efforts aimed at reducing skin cancer rates. In a climate where misinformation can spread rapidly, it is imperative to rely on scientific evidence and expert advice. Protecting our skin with sunscreen is not merely a recommendation; it is a critical step toward safeguarding our health against the dangerous effects of UV radiation.
