Debunking the “Glass Skin” Trend: Misleading Claims in 95% of Korean Skincare TikTok Videos
If you’ve been captivated by the viral “glass skin” trend on TikTok, dermatologists advise caution. A groundbreaking study presented at the European Academy of Dermatology and Venereology (EADV) Congress 2026 in Vienna, Austria has unveiled that nearly 95% of viral TikTok videos promoting Korean skincare and the “glass skin” trend harbor at least one potentially misleading claim. Moreover, these videos are largely devoid of essential safety information.
The researchers scrutinized 38 top-performing videos with a neutral TikTok account in May 2026 to minimize algorithmic bias. The results were startling: 84% of videos failed to account for different skin types, 45% advocated for combining multiple active ingredients without sufficient safety warnings, and 32% guaranteed immediate results. Only one video highlighted the risk of skin irritation, and none suggested consulting a dermatologist.
A related study at the same congress recorded real-world repercussions: 94 patients developed new or worsened skin conditions — including irritant contact dermatitis, acne flares, rosacea, and even superficial chemical burns — after adhering to social media-endorsed skincare routines. Chemical exfoliants (AHAs/BHAs) were implicated in 34% of cases, trailed by OTC retinoids (27%) and vitamin C products (14%).
“The most shocking revelation was the consistent absence of basic safety information,” stated lead author Dr. Maria Lúcia Paysano. Experts emphasize that the problem lies not with Korean skincare itself, but with the unregulated, one-size-fits-all manner in which its principles are disseminated to millions of viewers without any clinical oversight.
