  • By Vickie Le

Published:  Saturday, April 18, 2026

High-end brightening serum JUMISO Niacinamide 20 Serum is well-known for its gentle yet effective skincare approach. Its key ingredient, niacinamide, works to brighten the skin, minimize pores, improve pigmentation, and reduce dark spots, especially when combined with arbutin, vitamin C, tranexamic acid, and plant extracts.

BENEFITS
The JUMISO Niacinamide 20 Serum contains niacinamide (pure vitamin B3), which helps even out skin tone, control excess sebum, refine pores, and leave the skin smooth and healthy. It also helps fade dark spots, melasma, and hyperpigmentation caused by acne or UV exposure.

To enhance brightening effects, the JUMISO Niacinamide 20 Serum combines niacinamide (10% or 20%) with arbutin, vitamin C (ascorbic acid), and tranexamic acid (TXA). This powerful formula promotes cell regeneration, reduces discoloration, and smooths the skin’s surface for a radiant complexion.

Niacinamide (vitamin B3) in the JUMISO Niacinamide 20 Serum not only improves skin tone but also regulates oil production and supports pore tightening, making the skin clearer and more refined.

  • Niacinamide 10%
