Investigating Misinformation in Viral TikTok Skin Care Videos

In a groundbreaking study presented at the 2026 Congress of the European Academy of Dermatology and Venereology, researchers have discovered startling statistics regarding the world of TikTok and Korean skin care. Almost 95% of viral videos relating to Korean skin care and the trend for 'glass skin' were found to contain at least one potentially misleading statement. This revelation underscores significant concerns surrounding the safety and dermatological accuracy of the content that has captivated millions on social media platforms, particularly TikTok.

The concept of 'glass skin' — characterized by a clear, plump, and deeply hydrated complexion — has transformed into a global sensation, with many users seeking to replicate the look through popular routines showcased on platforms like TikTok. However, this study is among the first to critically examine the dermatological soundness and safety of such content.

Conducted in May 2026, the researchers analyzed a selection of the most popular videos derived from five search terms associated with Korean skin care. They adopted a neutral account without prior interactions to mitigate algorithmic bias, ensuring a thorough examination without preconceived notions. After applying exclusion criteria, researchers evaluated 38 videos based on the validity of the dermatological claims, the presence of safety information, and overall quality and reliability. This evaluation utilized the Global Quality Scale alongside a modified version of the DISCERN scale.

The findings from this close examination were alarming. Approximately 95% of the featured videos contained at least one misleading claim. Furthermore, a staggering 84% ignored individual skin type variations, while 45% advocated for the use of excessive combinations of active ingredients without proper safety recommendations. Notably, 32% of the analyses promised immediate results, an assertion prone to skepticism due to the complex nature of skin health.

Dr. Maria Lúcia Paysano, the lead researcher, expressed her surprise at the continual absence of essential safety information within these videos. Only one of the reviewed videos mentioned the risk of irritation, while just two addressed the importance of sun protection. Alarmingly, none of the videos consulted discussed the potential for contact dermatitis or advised viewers to seek professional guidance from a dermatologist.

All analyzed videos were ultimately classified as unreliable or of poor quality. Notably, none referenced external sources or provided citations. Around 82% of the content creators were influencers lacking medical qualifications, 11% were beauty brands, and 8% stemmed from other beauty content creators, with nary a video produced by a certified dermatologist.

The results clearly highlight a disconnect between the immense popularity of such content on platforms like TikTok and the reliability of the information being disseminated. Dr. Paysano cautioned that following these routines without professional guidance can lead to skin irritations, over-exfoliation, acne flare-ups, or disruptions to the skin barrier — especially when multiple active ingredients are used inappropriately.

The essence of the issues at hand is not necessarily the Korean skin care methods but rather how these established practices can be misrepresented or sensationalized into universal viral trends devoid of adequate safety disclaimers. Essential principles of skin care — such as gentle cleansing, proper hydration, and maintaining the skin barrier — can quickly get distorted when the information is shared in a viral format lacking expert context.

Dr. Paysano concluded with a warning, urging consumers to approach content that promises instantaneous and one-size-fits-all results with skepticism. As the trend of Korean skin care continues to dominate social media, it’s imperative to advocate for education based on dermatological science rather than viral popularity.
