TikTok’s Zinc Oxide Overnight Face Mask Trend: Expert Warnings
A viral TikTok trend encourages sleeping with thick zinc oxide cream for calmer, clearer skin by morning. Dermatologists and skincare experts caution that while zinc oxide has anti-inflammatory, antimicrobial, and barrier-supporting properties, overuse can clog pores, trap heat and debris, and disrupt the skin's natural repair. Dr. Zeba Umar and Dr. Maryam Zamani advise using zinc oxide as a short-term, targeted treatment rather than a nightly ritual, especially for oily or acne-prone skin. They recommend alternatives like ceramides, niacinamide, and azelaic acid for daily use.
