95% of Korean Skincare TikTok Videos Contain Misleading Claims
A new study presented at the 2026 EADV Congress found that nearly 95% of viral TikTok videos about Korean skincare and the 'glass skin' trend contained at least one potentially misleading claim. The research analyzed 38 videos identified from five Korean skincare search terms in May 2026, using a neutral account to minimize algorithmic bias. Among the findings, 84% of videos failed to account for different skin types, 45% promoted excessive combinations of active ingredients without safety recommendations, and 32% promised immediate results. Only one video mentioned the risk of irritation, two addressed sun protection, and none mentioned contact dermatitis or recommended consulting a dermatologist. All videos were rated as unreliable, and no video cited external sources. The majority of the content (82%) was created by non-physician influencers, with 11% from beauty brands and 8% from other beauty content creators. The researchers emphasize that while Korean skincare itself is not problematic, the lack of safety information in viral routines poses a risk of skin damage.
This study highlights significant misinformation in social media marketing, which can influence consumer trust and advertising practices within the beauty industry, but it is not directly about ad technology or marketing technology.

Study: 95% of Korean Skincare TikTok Videos Mislead
A study presented at the EADV Congress 2026 analyzed 38 viral TikTok videos about Korean skincare and 'glass skin' routines. It found that almost 95% contained at least one misleading claim, 84% failed to account for different skin types, 45% promoted excessive active ingredient combinations without safety guidance, and 32% promised instant results. Safety information was scarce: only one video mentioned irritation risk, two addressed sun protection, and none mentioned contact dermatitis or recommended consulting a dermatologist. Nearly 82% of videos were by non-physician influencers, with none by dermatologists. The study underscores a significant gap between content popularity and dermatological quality, urging consumer caution when following social media skincare advice.
K‑Beauty Boom: Why Korean Skincare Is Going Global
Korean skincare (K‑Beauty) has become a global commercial force driven by the broader "Hallyu" (Korean Wave), state-backed soft‑power, fast R&D cycles, omnichannel retail experiences and celebrity/influencer marketing. South Korea rose to the world’s No. 2 cosmetics exporter with $11.4 billion in exports in 2025. Agencies like Jung von Matt Hangang, retailers such as Olive Young, Sephora, Rossmann and dm, and startups (e.g., Yepoda, Tirtir) are shaping international expansion via pop‑ups, product placement in K‑dramas, celebrity endorsements and localized product strategies. German retailers are launching their own K‑inspired lines (Rossmann’s Isana K‑line produced in South Korea; dm’s Balea “Inspired by Korean Skincare” developed in Europe), prompting debate about authenticity and quality standards.
Meta Bans TikTok Ads on Its Platforms in Multiple Regions
Meta has banned advertising for TikTok on its platforms (Instagram, Facebook, WhatsApp) in several countries, including the USA, Japan, Vietnam, Canada, Egypt, Indonesia, and Thailand. This action, confirmed by Meta spokesperson Chris Sgro, prevents both ByteDance and third-party advertisers from promoting TikTok within Meta's ecosystem. The ban is seen as a competitive move amidst escalating rivalry between Meta, ByteDance, and YouTube. It may also be linked to Meta's recent $16.7 billion settlement with US states over youth safety, which includes conditions that require competitors like TikTok and YouTube to implement similar protective measures, suggesting a strategic pressure tactic to ensure they share the cost and responsibility of child safety initiatives.
