High-Strength Brightening Serum for Dark Spots, Pores & Uneven Skin Tone
The JUMISO Niacinamide 20 Serum is a concentrated Korean brightening serum formulated with 20% niacinamide, tranexamic acid (TXA), and glutathione to improve the appearance of dark spots, post-acne marks, hyperpigmentation, and uneven skin tone.
This multi-benefit formula also helps control excess sebum, refine the appearance of enlarged pores, and smooth uneven texture for a clearer, more balanced complexion. A Triple Centella Complex helps soothe visible redness and support the skin barrier, while hyaluronic acid replenishes moisture.
Its lightweight, fast-absorbing texture leaves a comfortable, non-sticky finish. Best suited to experienced users seeking targeted brightening and oil-control care.

FREQUENTLY ASKED QUESTIONS
Is 20% niacinamide too strong for beginners?
This serum is best for experienced niacinamide users. Beginners should start slowly (2–3 times per week) and monitor skin response.
Can I use this serum every day?
Yes. Once your skin adjusts, it can be used daily, but sensitive skin should increase frequency gradually.
Can I use this with vitamin C or retinol?
Yes — but to minimize irritation, it’s best to alternate routines or use vitamin C in the morning and retinol at night.
