Anua PDRN Hyaluronic Acid Capsule 100 Serum Mask is a sheet mask designed to deliver hydration and a dewy, firm-looking complexion. Each sheet is soaked in a serum formulated with salmon-derived PDRN (polydeoxyribonucleotide), hyaluronic acid, and collagen. PDRN is known for its role in supporting skin regeneration and moisture retention, while hyaluronic acid helps attract and lock in water for a plumped appearance. Collagen contributes to maintaining skin’s structural firmness. The mask aims to promote a glass-skin effect—characterized by a smooth, translucent, and luminous surface—without heaviness or stickiness. The capsule-referencing name indicates a concentrated serum texture that adheres closely to the skin during wear. This product is suitable for those seeking intense hydration, especially for dry or dehydrated skin types. It can also benefit skin that feels dull or lacks elasticity, as the ingredients work to improve surface smoothness and radiance. The mask sheet is designed to fit comfortably and release the serum evenly across the face over the recommended wear time. As a Korean skincare offering, it follows a layered approach common in multi-step routines, fitting well before moisturizer or as a standalone treatment step. Each pack contains ten individual masks sealed to maintain freshness and potency. The formula is generally considered gentle, making it appropriate for regular use, but a patch test is advisable for those with sensitive or reactive skin. Consistent use may help maintain a healthy moisture barrier and a more even, glowing complexion. This mask does not claim instant results but rather supports gradual improvement in skin hydration and overall appearance through sustained application.
