Sunscreen Misinformation on TikTok Gains Engagement Despite Low Volume

• •86.8% of TikTok videos analyzed promote sunscreen use, while only 6% critique it.
• •Videos containing misinformation about sunscreen receive significantly higher engagement.
• •Misinformation, despite being a minority, can influence public perception and health behaviors.

A recent study published in PLOS Digital Health analyzed 971 TikTok videos related to sunscreen, revealing that while 86.8% promoted sunscreen use, only a small fraction (6%) contained critiques. Notably, videos that discouraged sunscreen use received significantly higher engagement in likes and shares. Experts assert that misleading content, although a minority, can disproportionately influence public perception. Australian science communicator Dr. Michelle Wong emphasized that even subtle misinformation can be persuasive, especially when presented by perceived authorities. The study indicates that the dominant narrative on TikTok supports sunscreen use, but the few critical videos attract more interaction, raising concerns about the impact of misinformation. Overall, the findings suggest that while misinformation is not widespread, its engagement levels warrant attention.
