Crafted with a potent 13% pure Vitamin C formulation, this serum is tailor-made to address aging signs and dark spots effectively. Its key ingredient, Ascorbic Acid, diligently boosts collagen production, brightens dull skin, and evens out skin tone, leaving behind a radiant, firm, and spot-free complexion. Enriched with Super Vitamin E, which boasts 50 times more antioxidants than Tocopherol, it offers protection against environmental stressors and premature aging caused by free radicals. To mitigate any potential side effects, the COSRX The Vitamin C 13 Serum  is infused with Allantoin and Hyaluronic Acid, ensuring effective skin hydration and soothing any potential irritations.

Suitable for all skin types but ideal for those already familiar with Vitamin.
