Cosrx The Vitamin C 23 Anti-Aging Serum is designed to counteract the first signs of skin aging, fade acne scars, brighten the complexion, moisturize the skin, and provide a fresh-looking glow. Its key ingredients include vitamin C, vitamin E, allantoin & hyaluronic acid. 23% pure vitamin C (Ascorbic Acid) offers antioxidant activity, helps brighten the skin by reducing blemishes and blocking melanin synthesis caused by UV rays, and works to reduce wrinkles and enhance skin elasticity. Super vitamin E (Tocotrienol) is a form of vitamin E known for its high antioxidant activity, which is reportedly 50 times higher than tocopherol (another form of vitamin E). It can help stimulate collagen production, which is important for maintaining skin's firmness and elasticity. Hyaluronic acid is a well-known moisturizing ingredient that can retain and attract water, thereby helping the skin maintain hydration and suppleness. Allantoin is known for its soothing and irritation-relieving properties. It can help calm the skin and reduce redness or discomfort. The serum is described as hypoallergenic, which means it's formulated to minimize the risk of causing allergic reactions. Overall, Cosrx The Vitamin C 23 Anti-Aging Serum appears to be aimed at providing a range of benefits including antioxidant protection, skin brightening, hydration, and addressing early signs of aging.
