Numbuzin No.5 Vitamin Concentrated Serum - 30 ml

Numbuzin No.5 Vitamin Concentrated Serum pairs 5% Niacinamide and 4% Tranexamic Acid with Alpha-Arbutin and Glutathione to gently fade stubborn pigmentation and promote a more even-looking complexion. This nutrient-rich Korean serum offers concentrated brightening care for dull, uneven and pigmented skin with four targeted brightening agents.

Brightening ingredients can support a more luminous complexion in complementary ways, which is why this formula combines multiple proven skincare actives rather than relying on a single vitamin. Soothing Saccharum Officinarum (Sugarcane) Extract, Curcuma Longa (Turmeric) Root Extract and Tremella Fuciformis (Mushroom) Extract help balance the intensive formula with gentle care.
