Medicube TXA Niacinamide 15 Serum

Medicube TXA Niacinamide 15 Serum - 30ml

The Medicube TXA Niacinamide 15 Serum is a high-concentration brightening serum that combines 15% Niacinamide with Tranexamic Acid (TXA) to create one of the most potent yet well-tolerated brightening formulations available in Korean skincare. This serum is designed for those dealing with stubborn hyperpigmentation, melasma, post-acne marks, and generalised skin dullness.

Niacinamide at 15% concentration is among the highest available in a daily-use serum format. At this level, it inhibits melanin transfer from melanocytes to keratinocytes, visibly reducing dark spots and uneven tone with continued use. Niacinamide also strengthens the skin barrier, regulates sebum production, and reduces the appearance of enlarged pores, making it effective across multiple skin concerns simultaneously.

Tranexamic Acid (TXA) works through a complementary brightening mechanism by blocking the signalling between UV radiation and melanin synthesis, making it particularly effective against sun-triggered pigmentation and melasma. TXA is notable for its exceptional tolerance even in high-sensitivity skin types, and it is increasingly used in dermatological practice for treating persistent discolouration resistant to other brightening agents.

The combination of these two ingredients targets brightening through two distinct biological pathways, producing faster and more comprehensive results than either ingredient used alone. Clinically tested for safety and efficacy across all skin types.

How to Use

Apply three to four drops to cleansed, toned skin after essence or toner. Allow to absorb fully before applying moisturiser. Use morning and evening. Apply SPF50+ daily to maximise brightening results and prevent further pigmentation.
