JUMISO Niacinamide Dark Spot Serum 10% — 1.35 fl oz Water-Gel Brightening, Oil-Control

JUMISO 10% Niacinamide Dark Spot Serum is a lightweight, water-gel formula that brightens uneven tone, minimizes dark spots, and controls oil without pilling under makeup.

This serum combines a beginner-friendly 10% niacinamide with tranexamic acid and glutathione to target post-acne marks and hyperpigmentation while zinc PCA and succinic acid help manage shine and pore texture. The multi-molecular hyaluronic acid blend delivers weightless hydration and a dewy, non-sticky finish designed to layer smoothly under sunscreen and foundation. Dermatologist-tested and fragrance-free, the formula is made in Korea and intended for AM/PM use as part of a daily brightening routine.

How quickly will I notice brighter, more even skin?

Many users report visible changes within a few weeks because the serum targets several pathways that contribute to uneven tone. Clinical testing cited improvements in skin clarity and redness in about two weeks, though individual timelines vary depending on skin type and consistency of use.

• Study-based improvements in clarity and redness within 2 weeks for some participants
• 10% niacinamide helps reduce the appearance of dark spots and discoloration
• Tranexamic acid and glutathione support a brighter, more uniform complexion
• Consistent twice-daily use speeds visible results

Will this serum work under makeup and sunscreen without pilling?

Yes — the water-gel texture absorbs quickly and leaves a smooth, non-sticky finish intended to prevent the common pilling issue with heavier niacinamide serums. It creates a dewy, even base so SPF and foundation lay down without flaking.

• Lightweight, fast-absorbing water-gel formula
• Non-sticky finish suitable as a makeup primer
• Multi-molecular hyaluronic acid adds hydration without heaviness
• Recommended layering order: cleanser → 2–3 drops serum → moisturizer → SPF

Can this help oily, acne-prone, or textured skin?

The formula includes zinc PCA to help control excess sebum and succinic acid to support clearer-looking pores and smoother texture. Those ingredients aim to reduce midday shine and refine the appearance of uneven, orange-peel skin without over-drying, making the serum a good match for oily and combination skin types.

• Zinc PCA helps reduce visible oiliness and shine
• Succinic acid supports pore clarity and texture refinement
• Squalane and a Triple Centella complex soothe reactive or sensitive skin
• Balanced oil control preserves hydration for a glass-skin finish

How do I include this product in my morning and evening routine?

Use 2–3 drops after cleansing and before moisturizer. Apply it in the morning as a non-pilling base under sunscreen and makeup; for more intensive brightening, pair it at night with JUMISO 20% Niacinamide Serum. Always use SPF daily when treating dark spots or uneven tone.

• AM: cleanse → JUMISO 10% Niacinamide → moisturizer → SPF
• PM: cleanse → JUMISO 10% Niacinamide (or layer with JUMISO 20% at night) → moisturizer
• Vegan, cruelty-free, fragrance-free, dermatologist-tested
• Made in Korea; individual results may vary

Who is this for? This serum suits anyone looking to reduce the look of dark spots, post-blemish marks, and uneven tone while keeping shine under control—especially those with oily or combination skin who need a non-pilling base for makeup. It's also a good fit for people with sensitive or reactive skin who want brightening benefits without heavy fragrance or stinging actives. If you need intensive nightly correction, consider pairing this daytime-friendly 10% niacinamide formula with a higher-strength option at night.
