A recent study from the University of Alberta reveals that TikTok videos promoting misinformation about sunscreen are receiving the highest engagement, despite being a small fraction of the content. The study, published in the journal PLOS Digital Health, analyzed nearly 1,000 TikTok videos under popular sunscreen-related hashtags. It found that while 87% of the videos promoted sunscreen use, the 6% containing misinformation garnered more likes, comments, and shares.
The misinformation includes claims that sunscreen is toxic, causes cancer, or blocks health benefits. Alessandro Marcon, the study's lead author, noted that these videos often mention potential hormone disruption, cancer-causing agents, and microplastics in sunscreens. Dr. Anthony Rossi from Memorial Sloan Kettering Cancer Center emphasized the importance of correcting these falsehoods, stating, "Sunscreen does actually help and using it is not going to cause skin cancer or lead to vitamin D deficiency."
The study highlights a troubling trend where misleading content on TikTok resonates more with audiences, particularly among younger users. Dr. Marisa Garshick from MDCS Dermatology pointed out that social media is a significant source of skincare misinformation, contributing to rising skin cancer rates globally. She advises people to choose a sunscreen they will consistently use, whether chemical or mineral-based.
The research underscores the need for caution when consuming health information on social media. Marcon urged users to be wary of content that evokes extreme emotions or promotes fringe ideas. As sunscreen misinformation continues to spread, dermatologists like Dr. Molly Hales stress the importance of daily sunscreen use to protect against skin cancer.
