Dermatologists Warn 'Glass Skin' Routines Behind Skin Flares

New EADV Congress 2026 research reported by Allure and KCRA links viral, multi-step skincare routines to dermatitis, acne and rosacea flares.

The viral look meets the derm office

The pursuit of the ultra-dewy, poreless complexion dubbed "glass skin" — a Korean beauty trend amplified by Kylie Jenner and Hailey Bieber that surged in late 2025 into 2026, per Google Trends data cited by KCRA — is now landing patients in dermatology clinics. KCRA, carrying CNN's reporting, tells the story of Greta Costioli, once known as the "glass skin girl" on TikTok, who layered toners, serums and essences until she was applying seven layers of hydrating toner. She says the routine initially earned compliments, but she kept "compromising my skin barrier," producing small red bumps that grew more aggressive until she cut her steps back.

Why experts call this a surprise problem

The surprise is not that skincare can irritate — it is how consistently viral content omits the risks. KCRA reports that research presented September 29 at the European Academy of Dermatology and Venereology (EADV) Congress 2026 found nearly 95% of the most viral glass skin videos contained misleading claims. Of 38 videos assessed, KCRA says only one mentioned irritation risk, two addressed sun protection, none mentioned contact dermatitis risk or advised consulting a dermatologist — and none were produced by dermatologists. Co-lead author Dr. Maria Lúcia Paysano, a dermatology resident in Brazil, told KCRA she was "surprised by how consistent" the information gaps were.

The numbers behind the irritation

Allure reports a separate small observational study presented at EADV Congress 2026 followed 94 dermatology patients for 12 months who developed new or aggravated skin conditions after using products promoted on social media. According to Allure, irritant contact dermatitis appeared in 42% of patients, nearly 30% developed or had worsening acne, and 12% had rosacea flares; 7% experienced superficial chemical burns. Allure notes nearly 35% of reactions were tied to AHA or BHA chemical exfoliants, retinoid products were linked in 27% of cases, and 63% of patients used more than three active ingredients — though the study was small.

How to chase the glow safely

Both outlets say the answer is not abandoning skincare content but vetting it. "You can pursue the glow while taking care of the skin beneath it," Dr. Mona Gohara told KCRA, recommending a pause on scrubs, exfoliating acids and retinoids if the barrier is damaged, plus a gentle cleanser, barrier repair cream and sunscreen. KCRA says Dr. Jane Yoo favors a simple four-step routine: cleanser, one active, moisturizer and SPF. Allure's experts add practical guardrails — Dr. Cindy Wassef advises adding no more than one new product every one to two weeks, and Dr. Zeichner suggests running trending products past a dermatologist first.
