Cosrx The Vitamin C 13 Serum

Product Information

The Vitamin C 13 Serum is a gentle, water-based daily serum designed to brighten skin and improve overall tone without irritation. With a lightweight, fast-absorbing texture, it delivers hydration while working to fade dark spots, blemishes, and uneven pigmentation over time.

Perfect for everyday use, this serum is ideal for anyone looking to achieve a clearer, more radiant complexion without the heaviness or stickiness of stronger vitamin C formulas. It is especially suitable for beginners or those with sensitive skin who want a mild yet effective brightening solution.

Unlike heavier treatments, this formula feels fresh and comfortable on the skin, making it easy to layer into any morning or evening skincare routine. With consistent use, it helps restore natural glow, smooth dull areas, and support a more balanced skin tone.

Think of it as your daily skin vitamin—simple, effective, and gentle enough for regular use.
