Dermal filler injections pose serious risks when administered by untrained individuals or when food and drug administration (FDA) guidelines are not adhered to. This issue may potentially be compounded by a growing reliance on social media platforms for health information.
Our objective was to analyze the quality of health information in videos published on dermal filler on TikTok.
We searched three hashtags, #filler (2.4 billion views), #dermalfiller (132.8 million views), and #fillersinjection (137.0 million views) and assessed the top videos returned by TikTok's algorithm that met inclusion criteria. The quality of health information was evaluated using the DISCERN instrument, a validated tool that uses a 1 to 5 scale to assess consumer health information.
Videos received a mean DISCERN score of 1.64 (SD 0.33), indicating significantly low quality. 7% of the videos promoted non‐FDA‐approved uses of filler. Notably, videos posted by physician assistants or physicians received the highest mean scores (1.92 and 1.72) as well as videos categorized as educational (1.99).
This study analyzed the quality of TikTok's most popular dermal filler videos, revealing they are of significantly poor quality. Notably, videos posted by physician assistants or physicians, and those categorized as educational, demonstrated the highest quality. Dermatologists must acknowledge the prevalence of low‐quality TikTok content on dermal fillers and recognize their crucial role in educating patients to mitigate misinformation.
