Medicube TXA Niacinamide 15 Serum 30ml

Brighten. Even. Hydrate.

Reveal a more even, radiant-looking complexion with the Medicube TXA Niacinamide 15 Serum, a Korean brightening serum formulated with 10% Niacinamide + 5% Tranexamic Acid (TXA).

This targeted serum is designed for skin concerns such as dark spots, post-blemish marks, uneven skin tone and uneven texture. Medicube combines TXA with Niacinamide and Arbutin to provide comprehensive brightening and complexion-care support.

10% Niacinamide + 5% TXA

Niacinamide helps support a smoother-looking skin texture and more balanced complexion, while Tranexamic Acid is included to target the appearance of uneven pigmentation and dark spots.

Arbutin for Additional Brightening Care

The formula also contains Arbutin, another well-known cosmetic ingredient used in brightening-focused skincare.

Hydration + Barrier Support

Unlike a basic brightening serum, the formula also includes Panthenol, Betaine and a 10-layer Hyaluronic Acid complex, helping provide hydration and a comfortable skin feel. Medicube describes the product as lightweight, low-irritation and fragrance-free.
