A recent observational study presented at the European Academy of Dermatology and Venereology Congress 2026 raises concerns about skincare routines influenced by social media platforms like TikTok. The study monitored 94 dermatology patients over 12 months who reported new or worsening skin conditions after using makeup or skincare products promoted online.

The most prevalent issue identified was irritant contact dermatitis, affecting 42% of the participants. Nearly 30% experienced acne or exacerbations of existing acne, while 12% reported flares of rosacea or rosacea-like dermatitis. Additionally, over 10% experienced hyperpigmentation following skin inflammation, and 7% had superficial chemical burns.
Around 35% of patients had adverse reactions linked to chemical exfoliants containing alpha-hydroxy acids (AHA) or beta-hydroxy acids (BHA). Skin inflammation was associated with over-the-counter retinoid products in 27% of cases, and high-concentration vitamin C serums contributed to inflammation in 14% of patients. Niacinamide was linked to 11% of incidents.
The study also noted that 63% of the patients used more than three active ingredients in their skincare routines, with 14% engaging in complex, multi-step routines that combined various active ingredients, often leading to skin irritation. Despite 36% reporting a history of acne and 18% having rosacea, 35% had no prior skin issues.
Interestingly, nearly half of the participants admitted their skincare routines were heavily influenced by social media. Dermatologists expressed concern about the rise of such trends, advocating for caution when following beauty advice from non-experts. Dr. Ife J. Rodney, founding director of Eternal Dermatology + Aesthetics in Maryland, emphasized that many social media influencers lack the scientific knowledge necessary to provide medical guidance.
Another study published in 2025 in the journal *Pediatrics* highlighted the potential risks of popular products featured online. An analysis of videos from beauty content creators under 18 showed that each regimen had an average of six products, with the most-viewed videos containing up to 21 potentially irritating ingredients.
Dermatologists caution against layering products without understanding their active components, as this can inadvertently increase potency and lead to skin irritation. Dr. Cindy Wassef from Premier Health Associates in New Jersey advises consumers to be discerning about online recommendations, noting that many are paid advertisements that may omit crucial information about risks and side effects.
Dr. Joshua Zeichner from Mount Sinai Hospital in New York City also warned that many social media posts prioritize engagement over sound medical advice, often promoting complex regimes not suitable for all skin types.
Despite the risks, dermatologists encourage patients to engage with social media content critically. Dr. Zeichner noted that while he personally benefits from social media, it is essential to verify information with a dermatologist. Dr. Rodney suggested that if any social media product sparks interest, it should be discussed with a skincare professional, especially for those with acne-prone skin or sensitivities.
Caution is also advised with potent ingredients such as exfoliating acids and retinoids. Dr. Wassef recommended introducing new products gradually, ideally one at a time every one to two weeks, to monitor for irritation and avoid overwhelming the skin. Consulting with a dermatologist before making significant changes to one's skincare routine can help mitigate potential issues.
