Analysis of the content of YouTube videos discussing acne, psoriasis, and anti-aging skincare in Arabic.

An increasing number of patients turn to YouTube for medical information, driving the growth of research on medical video content, including in dermatology. The objective was to analyze the content of YouTube videos discussing acne, psoriasis, or anti-aging skincare in Arabic. This infodemiological study analyzed the most viewed videos on these topics. A usefulness score was created to compare "useful" and "not useful" videos, along with assessments of global quality and reliability. Among the 98 most viewed videos, 75 were analyzed. Non-professionals produced 53.33%. Median scores for quality (2/5), reliability (1/5), and usefulness (4/19) were low. Most videos (78.67%) were "not useful," while 21.33% were "useful," with the latter showing significantly higher quality and reliability. In conclusion, most videos present shortcomings both in terms of quality and reliability. Videos from professional sources are far fewer in number and less popular.
