Anua PDRN 100 Hyaluronic Acid Booster Toner is a hydrating face toner formulated for dry skin. It contains salmon DNA, collagen, and PDRN (polydeoxyribonucleotide), which are ingredients often used to support skin moisture retention and texture refinement. The inclusion of hyaluronic acid provides additional hydration, helping the skin maintain a plump and smooth appearance. This toner is designed to be used as a daily step in a Korean skincare routine, applied after cleansing to prepare the skin for subsequent products. The lightweight, watery texture absorbs without leaving a sticky residue. With a volume of 8.45 fluid ounces (250 ml), the product offers multiple weeks of use. It aims to contribute to a glass-skin-like glow by supporting the skin’s natural moisture barrier and improving overall surface smoothness. The formula is suitable for those with dry or dehydrated skin types who want a non-irritating, boosting toner that layers well under moisturizers or serums. As a booster toner, it can also be used for light exfoliation or as a hydrating mist throughout the day, depending on individual preference. The product is part of the Anua skincare line, which focuses on gentle, effective formulations. No artificial fragrances or harsh additives are listed in the ingredient profile, making it appropriate for sensitive skin when patch tested. Regular use may help reduce the look of dryness and flakiness, though results vary by skin condition.
