A powerful brightening serum formulated with Niacinamide, Tranexamic Acid, Glutathione, Alpha-Arbutin, Vitamin C Derivatives, and Panthenol to visibly fade dark spots, improve uneven skin tone, deeply hydrate, and reveal a radiant, glass-skin complexion.


Product Description

Transform dull, uneven skin with the Numbuzin No.5+ Vitamin Concentrated Serum, one of Korea's bestselling brightening serums designed to target dark spots, post-acne marks, and hyperpigmentation while improving overall skin radiance.

Its advanced brightening formula combines Niacinamide, Tranexamic Acid, Alpha-Arbutin, Glutathione, and multiple Vitamin C derivatives to visibly reduce discoloration and promote a clearer, more even complexion. Panthenol, Ceramide NP, and Hyaluronic Acid help strengthen the skin barrier and deliver long-lasting hydration, while Bifida Ferment Lysate and antioxidant-rich botanical extracts help maintain healthy, resilient skin.

Despite its potent brightening ingredients, the serum has a lightweight, fast-absorbing texture that layers comfortably under other skincare products without feeling sticky. With regular use, skin appears brighter, smoother, more hydrated, and noticeably more radiant.
