DESCRIPTION

Revitalise your complexion with COSRX The Vitamin C 13 Serum, a gentle yet effective brightening treatment designed for daily use. This potent serum features a 13% concentration of pure Vitamin C (Ascorbic Acid) to target dullness, uneven skin tone, and early signs of ageing without the irritation often associated with higher-strength formulas.

Key Benefits & Features:
  • 13% Pure Vitamin C: Works to fade stubborn dark spots, acne scars, and freckles while enhancing overall skin radiance.
  • Super Vitamin E (Tocotrienol): Boasts up to 50x more antioxidant power than standard Vitamin E, helping to neutralise free radicals and protect against environmental damage.
  • Triple Hydration & Soothing: Infused with Hyaluronic Acid, Allantoin, and Panthenol to lock in moisture and alleviate redness, ensuring a soft and smooth complexion.
  • Pore Refining: Helps minimise the appearance of enlarged pores and refines skin texture for a more polished look.
  • Sensitive Skin Friendly: Dermatologically tested and found to be non-irritating, making it a perfect beginner Vitamin C for those with reactive skin.
  • Lightweight & Non-Sticky: Features a watery, fast-absorbing texture that is lighter and more refreshing than the stronger Vitamin C 23% version.
  • Clinically Proven Results: Clinical tests showed a 3.94% improvement in skin brightness after just four weeks of consistent use.

Size: 20 ml

How to use

  1. Prep: After cleansing and toning, apply 2–3 drops onto the face and neck.
  2. Absorb: Gently massage or pat into the skin, starting from the centre and working outward.
  3. Layer: Follow with your favourite moisturiser. If used in the morning, always finish with SPF 30+ to protect the skin from UV-induced sensitivity.
  4. Storage: Store in the refrigerator after opening to maintain the stability of the pure Vitamin C and prevent oxidation.
