Why Anti-Sunscreen Content Is Going Viral on TikTok

Researchers found 87% of nearly 1,000 videos promoted sunscreen use, but misinformation drew the most engagement on TikTok.

  • On Thursday, a University of Alberta study published in PLOS Digital Health found that TikTok videos containing sunscreen misinformation generate significantly higher audience engagement than those promoting the product.
  • While 86.8% of analyzed content promoted sunscreen, the 6% containing health-related critiques—such as claims that products cause cancer or block vitamin D—consistently received more likes, shares, and comments.
  • Young people disproportionately rely on TikTok for health information, even as skin cancer rates soar; Alessandro Marcon, a research associate at the University of Alberta's Health Law Institute, warned that misinformation ranged from "sunburns aren't dangerous" to toxicity claims.
  • Dr. Melanie Palm, a board-certified dermatologist and cosmetic surgeon at Art of Skin MD, argues experts must simplify cancer prevention messaging to compete with the "outsized viral potential" of misleading content.
  • Regulators recently approved bemotrizinol, the first new sunscreen ingredient in more than 20 years, providing new options; experts say plain-language communication remains the most effective tool to counteract social media myths.
