TikTok Skincare Videos Lack Basic Safety Warnings, Study Finds

The viral obsession with "glass skin" has swept across social media, urging young users to chase that ideal of clear, smooth, and deeply hydrated complexions. But a fresh investigation suggests you might want to pause before trusting what you see on TikTok. Researchers from the European Academy of Dermatology and Venereology combed through Korean skincare content on the platform and found alarming gaps in safety.

Their analysis of 38 videos revealed that nearly 95 per cent contained at least one misleading claim. "What surprised us most was how consistently basic safety information was absent," said lead author Dr Maria Lúcia Paysano. She pointed out that only a single video mentioned the risk of irritation, while just two addressed sun protection. None warned about contact dermatitis risks or advised seeing a doctor.

The team created a dedicated TikTok account to sidestep algorithmic bias before hunting for these specific videos. They scrutinized each clip for dermatological advice, checking quality and reliability. The results were stark: 84 per cent of the content ignored different skin types entirely. Another 45 per cent pushed dangerous combinations of active ingredients without proper warnings, and 32 per cent promised instant results that simply do not exist in biology.

Not a single video was produced by a dermatologist. Instead, 82 per cent came from influencers, 11 per cent from beauty brands, and eight per cent from other content creators. "Our findings show a clear gap between the popularity of this content and the quality of the information provided," Dr Paysano noted. She warned that following these routines without personalized guidance could lead to irritation, over-exfoliation, acne flares, or damage to the skin barrier, especially when multiple active ingredients are mixed together.

Chemical exfoliants containing alpha-hydroxy acids or beta-hydroxy acids were the most common culprits, showing up in 34 per cent of cases. The Daily Mail reached out to the researchers for more details on the specific videos assessed, but the core message remains clear: social media advice often lacks medical oversight.

In response, a TikTok spokesperson told the Daily Mail that drawing conclusions from just 38 videos on a platform with over 100 million daily posts is deeply flawed methodology. "The facts are that we proactively remove harmful health misinformation," they stated. The company also highlighted their partnerships with fact-checkers and public health authorities to connect communities with reliable medical content.

A separate investigation has pulled back the curtain on how viral beauty hacks are hurting real people's skin. Researchers looked at 94 patients who walked into clinics with brand new or suddenly worsened skin problems after trusting advice found online. The most common culprits were chemical exfoliants packed with alpha-hydroxy acids (AHAs) or beta-hydroxy acids (BHAs). These products showed up in 34 per cent of all the bad cases. Following close behind were over-the-counter retinoids, which appeared in 27 per cent of incidents, vitamin C serums at 14 per cent, and niacinamide-containing products at 11 per cent.

The trouble isn't just that people are buying these items; it is how they are stacking them up. Nearly half, or 48 per cent, of the patients admitted to starting a completely new skincare regimen from scratch. Even worse, 63 per cent were trying to use more than three active ingredients at once. Dr Ouissal Hormi, who led this second study, noted that the real danger lay in how complex these routines became. 'Many patients were reproducing complex skincare routines involving several active ingredients simultaneously, often based on advice from non-medical influencers,' she said.

The physical toll was severe for many participants. Irritant contact dermatitis topped the list of reactions at 42 per cent. Acne followed in second place with 28 per cent of cases. Other issues included rosacea or rosacea-like dermatitis affecting 12 per cent, post-inflammatory hyperpigmentation hitting 11 per cent, and superficial chemical burns occurring in 7 per cent of patients. 'Combining several active ingredients can place excessive stress on the skin barrier since some have overlapping irritant effects,' Dr Hormi explained.

Before anyone throws their favorite products into the trash, it is important to get one thing straight: Korean skincare itself is not the villain here. The blame falls squarely on generic, one-size-fits-all routines pushed by social media algorithms. 'Viral' does not automatically mean safe, validated, or right for everyone,' Dr Hormi warned with directness. Dr Paysano added a final warning shot for consumers scrolling through feeds: 'Consumers should be cautious of content promising instant or universal results.'

If you already have a skin condition and start itching or burning after trying something new, stop immediately and see a dermatologist. Professionals also have work to do. Instead of ignoring these online trends, doctors can step in to make sure the information floating around is accurate and easy to understand. 'Anyone with an existing skin condition who develops irritation or is unsure whether a routine is appropriate for them should seek advice from a dermatologist,' Dr Paysano said.
