Best Eye Patches for Dark Circles? COSRX Expands Its Viral 5 PDRN Line with Hydrogel Eye Patches for TikTok’s New Arrivals
Bringing PDRN Into a Targeted Eye Patch Format
Following strong consumer response to its viral 5 PDRN skincare line, COSRX introduces the collection’s revitalizing benefits in a focused under-eye format. Building on the success of its best-selling Peptide Collagen Hydrogel Eye Patch, the newly released 5 PDRN Collagen Vitalizing Hydrogel Eye Patch delivers targeted care designed to visibly target dark circles and dullness.
At the core of the formula is a multi-source PDRN complex featuring five types of PDRN (Polydeoxyribonucleotide). While most PDRN products rely on a single source, commonly salmon-derived PDRN, COSRX incorporates a broader blend, including centella asiatica, green caviar, rice, and lactobacillus. These varied sources are selected for their smaller molecular sizes, supporting enhanced absorption and optimized delivery to the delicate under-eye area.
In addition to the five types of PDRN, the formula enhanced with a brightening complex featuring Niacinamide, Alpha-Arbutin, Vitamin C, and Glutathione, ingredients known to support a more even-looking and radiant tone. Designed as a multi-functional treatment, the hydrogel eye patch helps to:
brighten the appearance of dark circles
smooth the look of fine lines
deliver soothing hydration
