numbuzin No.5 Glutathione Vitamin Concentrated Serum

Reveal a brighter, more even complexion with this advanced No.5 Glutathione Vitamin Concentrated Serum, expertly formulated to target hyperpigmentation, post-acne marks and uneven skin tone. Powered by a potent blend of Glutathione, Vitamin C, Niacinamide and Tranexamic Acid, this lightweight daily treatment helps visibly fade dark spots while restoring radiance and clarity for healthier-looking skin.

To enhance results, the serum combines brightening actives with soothing and barrier-supporting ingredients, including Panthenol and Ceramides, which help maintain optimal hydration and skin comfort throughout the brightening process.
