Share information about your product.

COSRX The Vitamin C 13 Serum is the entry point into COSRX's Vitamin C line — gentle enough for sensitive skin and for daily use, where the 23% version is a stronger proposition. Same brightening work on blemishes, dark spots and freckles, at a concentration most skin tolerates from day one.

🎯 What It Does

• Fades dark spots and freckles — works on existing pigmentation with regular use
• Brightens overall tone — lifts dullness for a more even complexion
• Suits sensitive skin — formulated for daily use where higher concentrations sting
• Refines texture — smooths the skin surface over time
• Softens fine lines — supports the collagen work Vitamin C is known for
• Hydrates alongside — does not leave skin tight the way raw Vitamin C can

🔬 Key Ingredients

• Vitamin C 13% — an approachable concentration for daily, sensitive-skin use
