COSRX 5 PDRN Hyaluronic Acid Vital Hydrating Hydrogel Mask is an overnight hydrogel face mask designed to support hydration, firming, and a radiant glass-like complexion. This Korean skincare product features a combination of five types of PDRN (polydeoxyribonucleotide) derived from salmon DNA, along with Centella PDRN, to help improve skin texture and resilience. The inclusion of hyaluronic acid provides intense moisture retention, making it suitable for dry or dehydrated skin types. The hydrogel sheet adheres closely to the skin, allowing active ingredients to gradually absorb during overnight use. Its formulation is developed to be gentle, minimizing irritation, and is appropriate for normal, combination, and sensitive skin when used as directed. Each pack contains three individually sealed masks of 34 grams, making it a travel-friendly essential for maintaining a consistent skincare routine. The mask aims to deliver conditioning benefits through the synergy of PDRN complexes and botanical extracts, focusing on enhancing skin firmness without reliance on harsh additives. This product is best suited for individuals seeking a non-sticky, lightweight overnight treatment that supports skin barrier function and a more even tone. As with all skincare, patch testing prior to full application is advisable. The COSRX mask is part of a line known for straightforward, effective formulas that prioritize ingredient transparency and accessible pricing. It can be used as a weekly intensive care step or whenever the skin requires an extra boost of hydration and nourishment during rest.
