JUMISO 20% Niacinamide Dark Spot Serum 2-Pack — Tranexamic Acid + Glutathione, Fast-Absorbing Brightening & Pore-Refining Duo

JUMISO 20% Niacinamide Dark Spot Serum 2-Pack is a high-strength brightening serum duo that blends 20% niacinamide with tranexamic acid and glutathione to help even skin tone, reduce visible dark spots, and refine pores.

This value set includes two 1.35 fl oz (40 ml) bottles of a fast-absorbing water-gel serum formulated for daily use. The triple-active blend targets discoloration at multiple levels while supporting a comfortable skin barrier with Centella extracts, making it wearable under sunscreen and makeup. Designed in Korea and formulated fragrance-free, the serum aims to deliver a clarified, smoother finish often described as a glass skin look.

How will this serum affect dark spots and uneven tone?

The combination of 20% niacinamide, tranexamic acid (TXA), and glutathione works on several pathways linked to pigmentation and post-acne marks. Niacinamide helps reduce the transfer of pigment to skin cells, TXA addresses discoloration-related processes, and glutathione contributes antioxidant support—together they help the complexion appear more uniform with consistent use.

• 20% niacinamide concentration for pigment control and barrier support
• Tranexamic acid to reduce recurrent discoloration signals
• Glutathione for antioxidant brightening assistance
• Clinical data showing measurable improvements in skin clarity in 2 weeks

Will this serum work for oily or enlarged pores?

Yes—its lightweight, non-greasy water-gel texture absorbs quickly and helps smooth surface texture while controlling shine. The formula is tuned to refine the look of enlarged pores and reduce the appearance of rough, orange-peel skin, creating a more even canvas for makeup or a bare-glow finish.

• Silky finish that minimizes visible pore size
• Oil-control properties to reduce midday shine
• Improves surface texture for a smoother complexion
• Layers under sunscreen and makeup without pilling

Is this safe for sensitive or reactive skin?

Although the serum contains a high concentration of niacinamide, the formula includes a Triple Centella Complex to help soothe and support the skin barrier. The product is fragrance-free, vegan, and cruelty-free, and is formulated to minimize irritation while maintaining potency—however, patch testing is recommended for those with known sensitivities.

• Triple Centella Complex calms visible redness and discomfort
• Fragrance-free and quick-absorbing for reduced irritation risk
• Non-sticky, non-pilling texture suitable under layers
• Patch test advised for very reactive skin

How long does one pack last and why buy the 2-pack?

Each bottle contains 40 ml (1.35 fl oz), with the 2-pack providing about 3–4 months of daily use depending on amount applied. The two-bottle set offers a cost-effective way to maintain consistency—key for seeing brightening results—and is convenient for travel or sharing with a partner.

• Two full-size bottles for multi-month supply
• Economical choice for consistent daily use
• Travel-ready second bottle or sharing option
• Made in Korea, vegan and cruelty-free

Who is this for: This serum set is aimed at people seeking to reduce the look of dark spots, post-breakout marks, and uneven tone while refining pores and controlling shine. It suits anyone wanting a potent brightening step in their routine that layers well under sunscreen and makeup—especially those comfortable introducing high-strength actives with a soothing supporting formula. If you have very sensitive skin or are using other strong exfoliants or topical prescriptions, consult a dermatologist before adding a high-concentration active serum.
