New Study Uncovers Deceptive Claims in Viral TikTok Skincare Videos
In a revealing new study presented at the European Academy of Dermatology and Venereology (EADV) Congress 2026, researchers have discovered that nearly 95% of viral TikTok videos featuring Korean skincare routines and the much-coveted 'glass skin' trend are laden with misleading claims. This phenomenon, which showcases a pursuit for clear, smooth, and deeply hydrated skin, has become a global sensation, particularly on platforms like TikTok where skincare routines reach millions. However, the safety and accuracy of the information presented in these videos have largely gone unexamined.
Conducted in May 2026, this study is among the first of its kind to scrutinize the claims made in popular skincare videos. Researchers utilized a neutral account without an interaction history to minimize algorithmic bias while reviewing the most-watched videos linked to five specific Korean skincare search terms. After filtering out irrelevant content, a total of 38 videos were evaluated based on dermatological claims, safety information, and reliability, utilizing established quality assessment scales.
The results were alarming: almost 95% of the videos contained at least one deceptive claim, with 84% failing to consider various skin types. Additionally, 45% excessively praised ingredient combinations without appropriate safety advisories, and 32% promised immediate results that are unrealistic.
Dr. Maria Lúcia Paysano, the lead author of the study, expressed her surprise at the systematic absence of fundamental safety information in these videos. "Only one of the 38 videos mentioned the risk of irritation, while just two addressed the importance of sun protection. None discussed contact dermatitis risk or advised consulting a dermatologist," she stated.
Alarmingly, all examined videos were categorized as either unreliable or only somewhat reliable, with none referencing external sources or studies. Interestingly, about 82% of the content was produced by non-medical influencers, 11% by beauty brands, and only 8% by other beauty creators, highlighting a significant lack of professional oversight.
Dr. Paysano remarked on the stark contrast between the widespread popularity of such content and the quality of information being disseminated. "Following these routines without tailored advice can lead to irritations, excessive exfoliation, acne breakouts, or damaged skin barriers—especially when multiple active ingredients are combined inappropriately."
The researchers emphasized that Korean skincare itself is not problematic. Rather, the issue lies in how these skincare principles—like gentle cleansing, hydration, and barrier protection—are transformed into widely adopted viral trends on social media, often devoid of essential safety information.
"Consumers should be wary of content that promises immediate or universal results," adds Dr. Paysano, urging a cautious approach to viral beauty trends. As these claims proliferate across social media platforms, it becomes increasingly crucial for viewers to critically evaluate the content they consume.
