Overview
- A University of Alberta study published June 18 examined 971 of the most-viewed TikTok videos under five sunscreen hashtags and found the sample had amassed billions of views.
- About 86.8% of the videos promoted sunscreen while roughly 6% raised health-related critiques, but those critique videos earned significantly higher likes, shares, and comments than promotion-only posts.
- Only 1.5% of videos claimed sunscreen ingredients cause long-term harm and 1.2% suggested sunscreen prevents vitamin D, showing that specific false claims are rare yet highly engaging.
- Researchers and dermatologists warn that TikTok’s attention-driven algorithms favor contrarian, fear-based content and note that most promotional posts emphasize cosmetic benefits rather than cancer prevention, with only about 6% mentioning reduced skin-cancer risk.
- Regulatory context is shifting with the FDA’s June 9 approval of bemotrizinol for OTC sunscreens, and public-health groups are urging stronger platform moderation and clearer, targeted education to protect younger users.
