JUMISO Niacinamide 20% Dark Spot Serum — 1.35 fl oz, TXA + Glutathione for Even Tone & Pore Refining

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

This lightweight, fast-absorbing serum blends three targeted actives—niacinamide (Vitamin B3), tranexamic acid (TXA) and glutathione—plus a Centella soothing complex to tackle visible discoloration while supporting skin comfort. Formulated for daily AM/PM use, the texture is non-sticky and aims for a smooth, glass-like finish that layers well under moisturizers and makeup.

How does this serum address dark spots and uneven tone?

The formula uses multiple brightening mechanisms so pigment looks more balanced across the face. Niacinamide helps reduce the appearance of blotchiness, TXA works to reduce visible discoloration signaling, and glutathione provides antioxidant support for an overall more luminous look.

• 20% niacinamide for strong tone-correcting action
• Tranexamic acid to target recurrent or stubborn hyperpigmentation
• Glutathione for antioxidant brightening support
• Lightweight base for even application and quick absorption

Will it help minimize pores and control oil for a glass skin finish?

Yes—besides evening tone, the serum aims to refine texture and reduce the appearance of enlarged pores. Its silky finish helps smooth roughness and control excess shine, creating a clearer canvas that reflects light more evenly.

• Formulation designed to reduce orange-peel texture
• Helps visibly shrink pore appearance with regular use
• Controls sebum for a less shiny complexion throughout the day

Is this safe for sensitive or reactive skin?

Although the niacinamide concentration is potent, the formula includes a Triple Centella Complex to soothe and support the skin barrier. The product is dermatologist-tested for daily use, but those new to high-strength actives should introduce it gradually to assess tolerance.

• Centella asiatica extracts soothe visible redness and irritation
• Designed to be comfortable for sensitive skin when introduced slowly
• Non-pilling, non-sticky texture reduces layering friction

How quickly can I expect visible improvement?

Clinical testing reported measurable clarity and redness improvements within weeks, though results vary by individual and skin concerns. Consistent application as part of a daily routine will produce the most reliable outcome.

• Visible changes reported in study participants in about two weeks
• Best results seen with continued, twice-daily application
• Combine with sunscreen in AM to protect treated skin and maintain results

Who is this for: JUMISO 20% Niacinamide Dark Spot Serum is aimed at people wanting a stronger, science-forward brightening step—ideal for those with post-acne marks, general uneven tone, excess shine, or visible texture who can tolerate higher-strength actives. If you have highly reactive or compromised skin, patch-test first and introduce gradually; if safety is a concern, consult a skincare professional before use. For everyone else seeking a concentrated, multi-mechanism serum that layers easily into morning and evening routines, this product provides a potent option to help clarify and refine the complexion.
