Viral Korean Skincare Trends on TikTok Often Lack Dermatological Safety

Researchers analyzed 38 top-performing videos using neutral search parameters to evaluate the reliability of the global 'glass skin' phenomenon. The findings revealed that 84% of these clips ignored individual skin variations, while nearly half promoted the aggressive layering of active ingredients without warning users of potential side effects. Most concerning to the authors was the systemic lack of safety disclaimers: zero videos mentioned the risk of contact dermatitis, and only two emphasized the necessity of sun protection.

Lead author Dr. Maria Lúcia Paysano noted that all evaluated content was deemed unreliable, with 82% of the videos produced by non-physician influencers. Without professional oversight, these one-size-fits-all routines frequently lead to over-exfoliation, acne flares, and damaged skin barriers. The study underscores that while the core principles of hydration and gentle cleansing remain sound, the viral presentation of these routines on platforms like TikTok obscures the essential need for individualized care.
