Medicube TXA Niacinamide 15 Serum 30ml is a targeted brightening treatment designed to reduce dark spots, pigmentation, and uneven tone. Infused with tranexamic acid (TXA) and 15% niacinamide, it works synergistically to inhibit melanin formation while improving overall radiance and clarity. The serum helps refine pores, strengthen the barrier, and smooth texture for visibly brighter, more balanced skin. Antioxidants and soothing extracts provide additional protection against environmental stress. With regular use, the complexion appears clearer, refined, and glowing. Backed by a 15-year warranty for enduring reliability and satisfaction.
