JUMISO Niacinamide Dark Spot Correcting Serum 20% — 1.35 fl oz lightweight water-gel, brightening & anti-discoloration

JUMISO 20% Niacinamide Dark Spot Correcting Serum is a high-strength water-gel treatment designed to reduce the appearance of dark spots, even skin tone, and refine texture while layering smoothly under makeup.

This lightweight, fragrance-free serum combines 20% niacinamide with tranexamic acid, glutathione, and hexylresorcinol to address multiple causes of visible discoloration. The formula also includes a triple Centella complex to calm the skin and a silky water-gel base that absorbs quickly without pilling. It’s made in Korea, vegan and cruelty-free, and formulated for daily skin-cycle use when introduced gradually.

How does this serum target stubborn dark spots and uneven tone?

The serum uses a multi-step melanin defense approach: niacinamide helps reduce melanin transfer to the skin surface, tranexamic acid calms discoloration pathways, and brightening actives like glutathione and hexylresorcinol improve overall radiance. These ingredients work together to address both post-blemish marks and longer-standing hyperpigmentation.

• 20% niacinamide to inhibit melanin surfacing
• Tranexamic acid to support reduction of discoloration
• Glutathione + hexylresorcinol for enhanced brightening
• Targets post-blemish marks, sun spots, and dullness

Will the formula feel heavy or interfere with makeup and sunscreen?

No — the serum is a fast-absorbing water-gel that leaves a glass-skin finish without sticky residue. It’s formulated to layer smoothly under sunscreen and makeup, resisting pilling so your morning routine stays intact.

• Silky water-gel texture absorbs in seconds
• Non-sticky, no pilling under makeup or sunscreen
• Helps minimize the look of enlarged pores and shine

Is this high-strength product suitable for sensitive or reactive skin?

Although it contains a high concentration of niacinamide, the serum includes a Triple Centella Complex to soothe and support the skin barrier. Dermatologist-tested for daily use when introduced gradually, the product is designed to reduce irritation risk compared with bare high-strength actives.

• Triple Centella Complex calms visible redness
• Dermatologist-tested and fragrance-free
• Recommended gradual introduction to minimize sensitivity

How should I add this serum into my skincare routine safely?

Start slowly: use the serum 2–3 nights per week in weeks 1–2, progress to nightly by week 3, and eventually use AM and PM once adapted (always with morning SPF 30+). Avoid combining it in the same routine with retinol, high-strength vitamin C, or AHA/BHA — alternate nights instead.

• Week 1–2: 2–3 nights weekly after toner
• Week 3+: nightly, then AM/PM once tolerated
• Do not layer in the same routine with retinol or strong acids
• Pairs well with hydrating toners and panthenol serums from JUMISO

Who is this for: This serum is aimed at people who want a targeted, science-forward brightening treatment for dark spots, post-blemish marks, and dull texture without heavy or sticky residues. It suits those willing to introduce a potent active gradually, users seeking a product compatible with makeup and sunscreen layering, and anyone preferring vegan, fragrance-free, dermatologist-tested skincare made in Korea.
