Unveil brighter, more radiant skin with COSRX The Vitamin C 13 Serum, a potent formulation designed to illuminate your complexion. Infused with 13% pure ascorbic acid (vitamin C), this serum works diligently to fade dark spots, even out skin tone, and enhance overall skin luminosity. Experience the transformative power of vitamin C as it revitalizes your skin, leaving it with a youthful glow and a smoother texture. Say hello to a more radiant complexion with COSRX The Vitamin C 13 Serum.




  • Brightening Efficacy: With a potent concentration of 13% pure ascorbic acid, this serum effectively targets hyperpigmentation, dark spots, and uneven skin tone, revealing a brighter and more luminous complexion.
  • Antioxidant Protection: Vitamin C, renowned for its antioxidant properties, helps to neutralize free radicals and protect the skin against environmental stressors, resulting in a healthier and more youthful appearance.
  • Skin Renewal: By promoting collagen synthesis, this serum aids in skin renewal and regeneration, improving skin texture and reducing the appearance of fine lines and wrinkles.




  • Gradual Introduction: Start by using the serum every other day to allow your skin to acclimate to the potent vitamin C formulation. Once tolerance is established, you can gradually increase usage to daily application.
  • Sun Protection: Vitamin C can increase the skin’s sensitivity to the sun. Therefore, it’s essential to apply a broad-spectrum sunscreen with a high SPF during the day to protect your skin from sun damage.
  • Minimalist Formulation: COSRX The Vitamin C 13 Serum is formulated with minimal ingredients to ensure maximum efficacy and minimize the risk of irritation, making it suitable for most skin types.




  • Preparation: Start with cleansed and toned skin.
  • Application: Dispense a small amount of the serum onto your fingertips.
  • Gentle Patting: Gently pat the serum onto your face and neck, avoiding the delicate eye area.
  • Follow with Skincare: Allow the serum to absorb fully before proceeding with your moisturizer and other skincare products.
