COSRX – The Hyaluronic Acid 3 Serum 20 ml Feather-light moisture serum with 3% low-molecular hyaluronic complex and Hydrium™ Triple Moisture System: instantly replenishes water reserves, visibly plumps up dryness wrinkles and gives a plump “dewy glow” – without any stickiness or greasy film. 3% Low-Molecular Hyaluronic Acid – tiny molecules penetrate deeply, bind up to 1,000 times their weight in water and provide long-lasting, plump hydration. Hydrium™ Triple Moisture – high, medium & low molecular weight hyaluronic acid forms a multi-layered moisture film and prevents transepidermal water loss for 24 hours. Barrier protection & repair – Panthenol, beta-glucan and allantoin soothe redness, repair micro-tears and strengthen the lipid layer against environmental influences. Plumping & Smoothing – Adenosine smoothes fine lines, while trehalose and NMF amino acids improve skin elasticity and leave it silky soft. Feather-light aqua gel texture – absorbs in seconds, does not peel under cream or SPF and is perfect for layering (“7-Skin”). Clean, vegan & non-irritating – alcohol-free, fragrance-free, without parabens, mineral oil or silicones; cruelty-free & dermatologically tested – suitable for all skin types, even very sensitive or oily. In the morning and/or evening after toner, apply 2-3 drops to your face and neck and gently pat in. Then apply moisturizer; always use broad-spectrum sunscreen during the day to maintain the moisturizing effect.
