COSRX The Vitamin C 23 Serum 20ml

COSRX – The Vitamin C 23 Serum 20 ml High-dose brightening serum with 23% pure L-ascorbic acid powder: smoothes fine lines, visibly lightens stubborn pigment spots and provides powerful antioxidant protection – for a clear, even glow in just a few weeks. Maximum vitamin C boost – 23% pharmaceutically pure vitamin C stimulates collagen synthesis, reduces hyperpigmentation and protects against light-induced skin aging. Stabilized with vitamin E & tocotrienols – synergistic antioxidants preserve effectiveness, neutralize free radicals and extend shelf life. Moisture & Soothing – Panthenol, Sodium Hyaluronate and Betaine provide water, plump up dryness lines and reduce initial tingling. Silky, fast-absorbing texture – oily-light lotion spreads effortlessly and doesn't pill under SPF or makeup. pH ≈ 3.0 for optimal effectiveness – low pH environment promotes the absorption of ascorbic acid without severely irritating the skin. Clean & cruelty-free – free from fragrances, alcohol, parabens, and mineral oil; in a light-protected amber glass bottle. In the evening (or in the morning if you have robust skin), apply 2-3 drops to your face and neck and pat in gently. Follow with moisturizer; always apply broad-spectrum sunscreen during the day. For sensitive skin, introduce slowly (2 times per week). To keep fresh, store in a cool, dark place – preferably in the refrigerator.
