# COSRX The Vitamin C 13 serum 20ml

Revitalize a lackluster surface mantle and fade early hyperpigmentation marks with COSRX The Vitamin C 13 Serum 20ml : Vitamin C 13, a gentle yet highly stable antioxidant concentrate formulated for daily skin tone standardization. Calibrated at an optimal 13% concentration of pure Ascorbic Acid, this introductory brightening fluid sweeps away sallow undertones, addresses sun damage, and minimizes early fine dry lines without triggering the peeling or stinging associated with higher-strength treatments. Its silky, lightweight delivery fluid integrates seamlessly into your daily architecture—leaving a dull, fatigued, or sensitive combination canvas feeling remarkably supple, smooth, and radiantly luminous.

-   **Target Concerns:** Early Dark Spots & Sun Damage, Dull or Sallow Complexion, Uneven Tone Undercurrents, Early Fine Lines, Loss of Initial Elasticity
-   **Skin Compatibility:** Universal formulation (Specifically optimized for Vitamin C beginners, sensitive skin types, and combination profiles that find maximum-strength clinical serums too intense)
-   **Texture & Finish:** A light, cushiony fluid texture with an effortless, smooth glide. It sinks uniformly into the skin envelope within moments, establishing a comfortable, moisture-locked satin finish with zero heavy grease, sticky residue, or film.
