Medicube TXA Niacinamide 15% Serum is a high-performance Korean brightening serum that targets dark spots, uneven skin tone, and rough texture with a powerful triple-action formula. With 15% combined active concentration — 10% niacinamide and 5% tranexamic acid — this is one of the most potent brightening serums in K-beauty.
Tranexamic acid works at the deepest level to block melanin transfer, niacinamide brightens and controls oil at the surface, and arbutin gently fades existing dark spots. Together they deliver visible results: clearer, brighter, more even-toned skin that glows. Enriched with 10 types of hyaluronic acid and peptides, your skin stays hydrated and plump while the actives do their work.

- After cleansing and applying toner, squeeze a generous amount onto your fingertips.
- Apply directly to dark spots and areas of uneven tone, or spread across your entire face.
- Gently pat with your fingertips until fully absorbed.

- Always apply sunscreen in the morning — brightening actives increase sun sensitivity.
