JUMISO 20% Niacinamide Dark Spot Serum with TXA & Glutathione, 1.35 fl oz — Brightening, Pore-Refining

JUMISO 20% Niacinamide Dark Spot Serum is a high-strength brightening serum that combines 20% niacinamide, tranexamic acid, and glutathione to help reduce the look of dark spots, refine pores, and create a glass-skin finish.

This lightweight, fast-absorbing serum pairs potent brighteners with a calming Centella complex so you can use powerful actives without excessive irritation. Formulated for daily AM/PM use (introduce gradually if you’re new to concentrated ingredients), it aims to fade post-acne marks and uneven tone while controlling shine and smoothing texture for a refined, radiant complexion.

How does this serum target dark spots and uneven tone?

The formula uses three complementary brightening actives that work at different steps of the pigmentation process. Niacinamide helps reduce visible discoloration and supports skin barrier function, tranexamic acid targets stubborn hyperpigmentation, and glutathione provides antioxidant brightening support.

• 20% niacinamide to visibly reduce dark spots and improve clarity
• Tranexamic acid (TXA) for targeted control of melanin-related discoloration
• Glutathione for antioxidant support and overall radiance

Will this serum irritate sensitive skin or cause redness?

Although the active levels are high, a triple Centella complex (Asiaticoside, Madecassic Acid, Asiatic Acid) is included to soothe and support a comfortable-feeling skin barrier. The formula is dermatologist-tested and designed for gradual introduction to reduce the risk of sensitivity.

• Soothing Centella components calm the look of redness
• Dermatologist-tested for daily AM/PM use—start slowly if new to strong actives
• Non-sticky, non-pilling finish suitable under moisturizers and makeup

How quickly can I expect to see results and what improvements are typical?

Clinical testing reported visible improvements in skin clarity and redness within two weeks for study participants; individual results vary. The serum is designed to deliver both short-term refinements in texture and longer-term reduction in discoloration with consistent use.

• Noticeable skin clarity improvement reported in clinical testing as soon as two weeks
• Pore-minimizing and oil-control benefits for smoother surface appearance
• Continued use supports gradual fading of post-blemish marks and uneven tone

How should I incorporate this into my routine safely?

Apply a few drops to clean skin once or twice daily depending on tolerance, then follow with moisturizer and sunscreen in the morning. Because of the high niacinamide concentration, begin with alternate-day use if you have sensitive skin and increase frequency as your skin adapts.

• Use after cleansing and before heavier serums or moisturizers
• Start with every-other-day application if sensitive, then increase to daily use
• Always pair with broad-spectrum SPF in daytime routines to protect results

Who this is for: JUMISO 20% Niacinamide Dark Spot Serum is aimed at people seeking a potent brightening step for uneven tone, post-acne marks, and enlarged pores who want a silky, glass-skin finish. It suits those comfortable introducing high-strength actives into their regimen, including individuals with combination or oily skin concerned with shine and texture, and those looking for a dermatologist-tested option with calming Centella support for more sensitive skin types.
