COSRX's eye patches

COSRX built its reputation on the Advanced Snail 96 Mucin Power Essence — a no-frills product that became a holy-grail recommendation in dermatologist communities. The brand’s 2024-2026 expansion has centered on PDRN, with the new 5-PDRN Complex line (toner, serum, cream, eye patches) launching on US Amazon in spring 2026.
