No.5 Vitamin Concentrated Serum

Numbuzin No.5 Vitamin Concentrated Serum is a powerful brightening formula designed to improve skin tone clarity and enhance overall radiance. The serum combines niacinamide, tranexamic acid, alpha arbutin, and two forms of vitamin C to help reduce dullness and support a more even looking complexion.

Glutathione provides antioxidant support, while panthenol and sodium hyaluronate deliver deep hydration for a smooth and comfortable skin feel. Ceramide NP helps reinforce the skin barrier, beta glucan soothes and calms the skin, and adenosine adds visible anti aging support. The lightweight texture absorbs quickly, making it suitable for daily use to achieve brighter, refined, and more luminous skin.
