Abstract
Background With TikTok's rising popularity as a hub for health information dissemination, the quality and nature of such content require assessment. This study investigates the popularity and quality of the top 100 most-liked videos tagged with "#acne" on TikTok. This study aims to examine the engagement and quality of acne-related content on TikTok, assess contributions from diverse sources, including physicians and non-physicians, and guide healthcare professionals in leveraging this platform for public health education. Methodology A cross-sectional analysis of the top 100 most-liked videos tagged with "#acne" on TikTok as of June 7, 2023, was conducted. Parameters assessed included the profession of the creator, gender, specialty, content type, and other observable characteristics. The quality was measured using the DISCERN tool. Results Of the dataset, 38 videos were by physicians and 29 by non-physicians. Physician-created content had higher mean views, likes, comments, shares, and favorites than non-physician-created content. Videos by dermatologists and non-dermatologists received similar engagement. Videos sharing personal experiences achieved the highest DISCERN score. Overall, DISCERN scores were uniformly low across all categories. Conclusions Physicians, especially dermatologists, are trusted sources of acne-related information on TikTok. The study underscores the need for professionals to provide reliable, evidence-based information on such platforms, guiding effective health communication in the digital age.
