The Medicube TXA + Niacinamide 15% Serum is a high-potency Korean brightening serum formulated with 5% Tranexamic Acid (TXA), 10% Niacinamide, and 2% Arbutin to visibly fade dark spots, melasma, and post-acne marks. This lightweight, fragrance-free 30ml formula targets stubborn hyperpigmentation while supporting skin barrier health and delivering 72-hour hydration for a clearer, more even, more radiant complexion across all skin types.
Why This Brightening Serum Works
Medicube combines its highest TXA concentration with a clinically supported trio of brightening actives that addresses pigmentation at the source rather than masking it. Tranexamic Acid interrupts excess melanin signaling that drives melasma and post-acne marks, Niacinamide refines pores and strengthens the skin barrier, and Arbutin gently brightens uneven patches for visibly balanced tone. In clinical testing conducted by the Custis Life Science Research Center, the serum boosted radiance by 15.6% after a single use and improved skin texture by 7.5% after one week of consistent use, giving you fast visible feedback alongside steady long-term fading.
Ideal For
This serum suits adults dealing with hyperpigmentation, melasma, post-acne dark spots, or uneven skin tone, particularly those drawn to high-strength Korean skincare formulations. The low-irritation, fragrance-free profile is suitable for all skin types, including sensitive, oily, combination, and acne-prone skin. UAE shoppers exposed to harsh sun and humidity will appreciate the lightweight watery texture and dermatologically tested formula. Patch test on a small area before first use and discontinue if irritation occurs.
