JUMISO 20% Niacinamide Dark Spot Serum – 40ml

JUMISO 20% Niacinamide Dark Spot Serum visibly fades dark spots, minimises pores and delivers a glass skin finish through the most potent brightening triple-active formula in Korean skincare — 20% niacinamide, tranexamic acid and glutathione working simultaneously on every mechanism of hyperpigmentation.

Dark spots are stubborn because most brightening serums only address one of the three pathways that create them. Melanin is produced, transferred to skin cells and accumulates visibly — three separate biological steps, each requiring a different active ingredient to interrupt. A vitamin C serum targets melanin production alone. A niacinamide serum at standard concentration interrupts melanin transfer alone. A single-active brightening formula is fighting one mechanism while the other two continue unchecked. The dark spot fades partially. Returns. Fades again. Returns again. The cycle is not a product failure — it is a formula architecture failure.

JUMISO 20% Niacinamide Dark Spot Serum interrupts all three pathways simultaneously — 20% niacinamide at one of the highest concentrations available in Korean consumer skincare, tranexamic acid targeting melanin synthesis at the source and glutathione addressing the oxidative activity that accelerates pigmentation — in a centella-soothed formula gentle enough for sensitive skin. 20% niacinamide is the concentration that clinical K-beauty has established as genuinely effective for visible dark spot reduction and pore minimisation — not the 5% or 10% that most standard brightening serums use to justify a niacinamide claim without delivering a niacinamide result. Delivered by JUMISO — the Seoul-based brand founded on the principle that real visible results are the only results worth formulating for.

What you get:

• 20% niacinamide — at twice the concentration of most leading niacinamide serums, visibly interrupting melanin transfer from melanocytes to keratinocytes, minimising pore appearance, regulating sebum production and producing progressive tone evenness across the full face with consistent daily use
• Tranexamic acid — the gold standard hyperpigmentation active that works independently of niacinamide by inhibiting the plasmin-activated pathway that triggers excess melanin synthesis, making it particularly effective against stubborn melasma and sun-induced pigmentation that resists standard brightening formulas
• Glutathione — the master cellular antioxidant that visibly supports overall skin tone brightness by neutralising the oxidative activity that drives melanin overproduction and accumulation, addressing the third dimension of pigmentation that niacinamide and tranexamic acid alone cannot reach
• Centella asiatica soothing complex — the K-beauty hero botanical that allows this formula's high-concentration active profile to be used by sensitive skin without the redness, irritation or barrier disruption that 20% niacinamide would typically produce without adequate calming support
• Glass skin finish — the visible surface refinement from combined pore minimisation, tone evenness and sebum control that produces the smooth, poreless, luminous complexion that defines Korean glass skin

The triple-active mechanism is what makes this formula categorically different from single-ingredient brightening serums — niacinamide stops melanin transfer, tranexamic acid stops melanin production and glutathione stops the oxidative trigger that activates both processes. Remove all three simultaneously and the pigmentation cycle has nowhere to continue. The dark spots already present fade progressively. New ones form significantly more slowly. The skin tone evenness that results is comprehensive rather than partial — visible in photographs within four to six weeks of consistent daily use.

This is for the woman whose dark spots, melasma or post-inflammatory pigmentation have resisted every single-active brightening serum she has tried — who needs the triple-mechanism formula that addresses production, transfer and oxidative activation simultaneously, in a sensitive-skin-safe formula that delivers 20% niacinamide without the irritation that concentration typically produces.
