COSRX The Vitamin C 13 Serum: Brighten, Hydrate & Fight Early Signs of Aging

Achieve a luminous, youthful complexion with COSRX The Vitamin C 13 Serum, a lightweight K-Beauty formula powered by 13% pure Vitamin C (Ascorbic Acid), Super Vitamin E (Tocotrienol), and Hyaluronic Acid. Designed to boost skin brightness and combat early signs of aging, this serum visibly reduces dark spots, pigmentation, and uneven skin tone while delivering deep moisture to plump fine lines and restore a healthy, radiant glow.

Experience the refreshing sensation as this lightweight, fast-absorbing serum glides onto the skin, instantly hydrating and revitalizing your complexion. With every application, pure Vitamin C and antioxidant-rich botanicals work in harmony to renew skin texture, even tone, and protect against environmental damage — leaving your skin looking brighter, smoother, and visibly younger.

Why Choose COSRX The Vitamin C 13 Serum?

This brightening serum delivers exceptional results with these key benefits:

  • 13% Pure Vitamin C (Ascorbic Acid): Potent brightening agent that fades dark spots, evens skin tone, and stimulates collagen production for a firmer, more youthful complexion.
  • Super Vitamin E (Tocotrienol): A powerful antioxidant that combats skin aging, slows down damage from free radicals, and enhances the efficacy of Vitamin C.
  • Hyaluronic Acid: Delivers deep moisture to the skin, reducing the appearance of fine lines and wrinkles for a plump, dewy, and hydrated complexion.
  • Lightweight K-Beauty Formula: Fast-absorbing, non-greasy texture suitable for all skin types, including sensitive and dry skin.

How to Use

After cleansing and toning, apply a few drops to the face. Gently massage into the skin using fingertips, starting from the center of the face and working outwards for maximum absorption. Follow with moisturizer and SPF in the morning.
