Cosrx The Vitamin C 13 Serum 20ml

The Cosrx The Vitamin C 13 Serum is designed as a gentle, entry-level Vitamin C treatment. It is particularly popular for those who find high-concentration serums (like 20% or 23%) too irritating but still want the brightening and anti-aging benefits of pure Vitamin C. 

Key Benefits

The serum focuses on three main areas: brightening, hydration, and texture refinement.

Brightens & Evens Tone: The 13% pure Vitamin C helps fade hyperpigmentation, acne scars, and dark spots by inhibiting melanin production. 

Antioxidant Protection: It protects skin from environmental stressors like UV rays and pollution, which helps prevent premature aging. 

Deep Hydration: Unlike some drying Vitamin C serums, this formula includes Hyaluronic Acid to plump the skin and maintain moisture. 

Refines Texture: Clinical trials showed a 20% improvement in skin roughness after 4 weeks, helping to smooth out the skin’s surface. 

Pore Care: It has been shown to reduce pore volume and area, making skin look more refined.
