Study Finds 6% of TikTok Sunscreen Videos Drive Outsized Engagement With False Health Claims
3 articles · Updated · Popular Science · Jun 18
Summary
971 top-viewed TikTok videos with 8.7 billion total views showed that sunscreen-critical posts were a small minority, yet they drew more likes, shares and comments than pro-sunscreen content.
86.8% of videos promoted sunscreen use, while 6% raised health criticisms; 1.5% claimed ingredients cause long-term harm and 1.2% said sunscreen blocks vitamin D absorption.
University of Alberta researchers said TikTok creators often framed sunscreen around beauty and skincare rather than cancer prevention, while the platform appeared to reward more conspiratorial claims with higher engagement.
Young users are a key concern: a 2024 Orlando Health study found 1 in 7 adults under 35 believed daily sunscreen was more harmful than direct sun exposure, and 37% of Gen Z said they used sunscreen only when prompted.
The findings land as melanoma deaths in the U.S. were projected above 8,000 in 2025 and as regulators approved bemotrizinol on June 9—the first new FDA-approved sunscreen ingredient in more than 20 years.
As TikTok myths fuel a youth skin cancer surge, can a new FDA-approved ingredient finally win back trust in sunscreen?
Are 'clean' sunscreens truly safer, or a marketing myth hiding risks like microplastics and undisclosed chemical boosters?
If online misinformation is driving a deadly crisis, why aren't social media platforms held accountable for the health advice they amplify?
Sunscreen Misinformation on TikTok: How Viral Myths Are Fueling a Surge in Tanning and Skin Cancer Risk Among Gen Z
Overview
A recent University of Alberta study highlights the widespread problem of sunscreen misinformation on TikTok, warning users to be extremely cautious when seeking health advice online. The study urges people to be skeptical of content that promotes products, stirs up strong emotions like fear, or pushes ideas that do not match scientific consensus. These types of posts can easily spread and influence behavior, making it harder for users to tell the difference between trustworthy and misleading information. The findings stress the importance of critical thinking and relying on evidence-based sources for health decisions.
