Product Overview

Cosrx The Vitamin C 13 Serum (20ml / 0.67 fl. oz.) is a lightweight daily facial treatment formulated for skin brightening and texture refinement. Made in South Korea, this authentic Korean skin care serum targets blemishes, dark spots, freckles, and uneven skin tone while minimizing the appearance of visible pores. Featuring a gentle 13% pure Vitamin C dose paired with soothing ingredients, it serves as an effective hyaluronic acid serum that delivers hydrating antioxidant care without heavy oils or irritation.

Key Ingredients

  • 13% Pure Vitamin C (Ascorbic Acid): Helps improve discoloration, post-acne spots, and uneven skin tone.
  • Tocotrienol (Super Vitamin E): Delivers up to 50 times greater antioxidant efficacy than standard Tocopherol to protect skin against free radical damage.
  • Hyaluronic Acid & Allantoin: Provides deep moisture retention and helps soothe skin irritation.
  • Brightening & Conditioning Complex: Formulated with Niacinamide, Glutathione, Licorice Root Extract, Panthenol, and Squalane to support smooth texture and a healthy glow.

How to Use

  1. Cleanse your skin thoroughly and apply your favorite toner.
  2. Dispense a few drops of serum onto your face.
  3. Use your fingertips to gently massage and absorb the serum, starting from the inside of the face and working outward towards the edges.

Storage Tip: Pure Vitamin C can oxidize when exposed to light, heat, and air. Store this serum in a cool, dark place or refrigerator after opening to preserve freshness and potency.
