As Europe grapples with unprecedented heatwave conditions, troubling misinformation surrounding sunscreen use is gaining traction on social media. Influencers and some podcasters are advocating for the abandonment of sunscreen, claiming that it may contribute to skin cancer rather than protect against it. However, experts are quick to highlight that the actual evidence contradicts these assertions, underscoring the importance of sun protection during this record-breaking heat.
Misleading Claims Take Centre Stage
With temperatures soaring across the continent, a wave of misleading claims about sunscreen has emerged online. One viral assertion suggests that the chemicals in sunscreen increase cancer risk, while another erroneously states that sunlight is essential for fighting cancer due to its role in vitamin D production.
Social media platforms are flooded with content promoting these dangerous misconceptions. The hashtag #antispf, which sought to undermine the importance of sunscreen, was banned by TikTok in 2025, yet similar sentiments continue to proliferate across various channels.
John Dombrowski, a cosmetic chemist based in the United States, cautioned against the flawed logic of linking increased skin cancer rates with the widespread use of sunscreen since the 1940s. “Correlation does not equal causation,” he stated, urging the public to separate fact from fiction.
Rising Skin Cancer Rates: What the Data Shows
Statistics from Cancer Research UK reveal a stark increase in melanoma skin cancer cases, with incidence rates rising by over 164 per cent in the UK since the early 1990s. The charity attributes this surge to several factors, including an ageing population and improved detection methods, rather than the use of sunscreen.
“Many people are becoming more aware of melanoma, which naturally leads to more diagnoses,” noted Dombrowski. He emphasised that the rise in awareness and advancements in medical technology play significant roles in these statistics.
In fact, during recent studies, it was found that 59 per cent of Americans expressed concern about the chemicals in sunscreens. These fears, however, are largely unfounded, as the presence of chemicals does not inherently indicate danger. “Everything is a chemical; even the air we breathe,” Dombrowski added, reminding the public of the pervasive nature of chemicals in everyday life.
The Proper Use of Sunscreen: A Crucial Message
Experts emphasise that the effectiveness of sunscreen is often compromised due to improper application. Anthony Young, a professor at King’s College London, explained that incorrect usage leads to inadequate protection and can result in sunburns, further perpetuating misconceptions about sunscreen’s efficacy.
The NHS recommends that adults apply approximately six to eight teaspoons of sunscreen to cover their entire body, ensuring that it is spread evenly across all exposed skin. It should be applied at least 30 minutes prior to sun exposure and reapplied every two hours or immediately after swimming or sweating to maintain optimal protection.
Young highlighted a common pitfall: “Many individuals think they’re protected but are not applying enough product. This leads to a false sense of security and ultimately to more sunburns.”
Regulatory Standards and Safety Measures
In the UK, sunscreens are regulated under strict safety and efficacy guidelines, unlike some countries where they may be classified differently. The rigorous processes involved in bringing a sunscreen to market mean that manufacturers must provide extensive documentation and pass numerous tests to ensure both safety and effectiveness.
Young reiterated the extensive work required to gain approval for sunscreen products, stating, “Getting a sunscreen approved involves a vast amount of work and is subject to stringent testing. It’s not a simple process.”
While TikTok has not commented directly on the misinformation surrounding sunscreen, the platform has implemented community guidelines to combat misleading content that poses significant health risks. In 2024, TikTok introduced a UK clinician-creator network to promote accurate health information, featuring NHS-qualified professionals.
Why it Matters
As misinformation about sunscreen continues to spread during this critical heatwave, it is essential for the public to rely on expert advice rather than unverified social media claims. Sunscreen remains a vital tool in skin cancer prevention, particularly as temperatures rise and sun exposure increases. By understanding the facts and properly using sunscreen, individuals can protect themselves from harmful UV rays and enjoy the summer months safely.
