A recent observational study presented at the European Academy of Dermatology and Venereology (EADV) Congress 2026 highlights potential risks associated with beauty routines inspired by TikTok. The study followed 94 dermatology patients over a year, revealing that many experienced new or worsened skin conditions linked to social media-promoted products.

Irritant contact dermatitis was the most reported issue, affecting 42% of participants. Nearly 30% developed acne or experienced acne flare-ups, while 12% reported rosacea exacerbations. Additionally, over 10% faced hyperpigmentation post-inflammation, and 7% encountered superficial chemical burns. Chemical exfoliants containing alpha-hydroxy acids (AHA) or beta-hydroxy acids (BHA) were responsible for adverse reactions in about 35% of patients. Retinoid-based products and high-concentration vitamin C serums were implicated in 27% and 14% respectively, whereas niacinamide accounted for 11% of reactions.
The majority of patients, or 63%, used over three active ingredients in their skincare routines, with 14% employing complex multi-step approaches that combined several active ingredients. Close to half of the patients stated their skincare routine was inspired entirely by social media, with skepticism expressed by dermatologists regarding the advice circulated online.
Dr. Ife J. Rodney, founding director of Eternal Dermatology + Aesthetics in Maryland, voiced concerns over the lack of scientific understanding among social media influencers offering beauty advice. A separate 2025 study published in the journal Pediatrics reviewed 100 videos from young beauty content creators and found an average of six products per routine, with some top viewed videos featuring as many as 21 potentially irritating ingredients.
Experts caution that layering multiple products can lead to unintentional excess exposure to active ingredients, which increases the likelihood of irritation. Dr. Cindy Wassef from Premier Health Associates recommends checking the credibility of sources sharing skincare recommendations, as many posts may be commercial and lacking in comprehensive risk assessment.
Dr. Joshua Zeichner from Mount Sinai Hospital added that many social media posts focus on engaging viewers through shock rather than offering scientifically-backed advice. He emphasized that while some ingredients may be beneficial for certain individuals, they might not be suitable for everyone.
Dermatologists advocate for a thoughtful approach to social media skincare recommendations rather than complete avoidance. Dr. Zeichner suggests vetting any information with a dermatologist, especially for those with skin sensitivities or pre-existing conditions. Dr. Rodney encourages patients to consult a dermatologist before trying new products to ensure compatibility with their skin type.
Dr. Wassef warns against introducing multiple new products at once, advising users to start with one new product every one to two weeks, monitoring for irritation signs. Dermatologists stress the importance of professional guidance in navigating skincare to prevent future skin issues.
