JUMISO Niacinamide Brightening Serum — 10% Niacinamide, TXA & Glutathione, Lightweight Water-Gel 1.35 fl oz

This daily-use serum blends a clinical-strength 10% niacinamide dose with complementary brighteners—Tranexamic Acid (TXA) and Glutathione—plus skin-soothing Centella extracts. The fast-absorbing water-gel texture hydrates with hyaluronic acid and layers cleanly under sunscreen and makeup without pilling, making it easy to slot into AM routines. Formulated in Korea, it’s fragrance-free, vegan, and created to be approachable for niacinamide newcomers and sensitive skin types.

How will this serum change my daily AM routine?

Use 2–3 drops after cleansing and before moisturizer and SPF. The non-tacky water-gel absorbs quickly so you can apply sunscreen and makeup without delays or product clumping.

• Applies smoothly under SPF and foundation
• Dries quickly with a dewy, non-greasy finish
• Suggested AM application for daytime brightening
• Pairs with a PM treatment for intensified results

What active ingredients are inside and what do they do?

The formula centers on 10% niacinamide for barrier support and tone improvement, while Tranexamic Acid and Glutathione target discoloration and uneven patches. Hyaluronic acid hydrates, and a Triple Centella complex soothes reactive or sensitive skin.

• 10% Niacinamide — evens skin texture and sebum control
• Tranexamic Acid (TXA) — helps reduce the look of dark spots
• Glutathione — antioxidant support for brighter appearance
• Triple Centella Complex — calms and supports the skin barrier

Is this serum suitable for sensitive or beginner users?

Yes. The formulation emphasizes gentle brightening and barrier-calming ingredients to minimize irritation for those new to niacinamide or with sensitive skin. Clinical data linked to the product shows measurable improvements in clarity and redness within two weeks for many participants, though individual responses vary.

• Designed for first-time niacinamide users
• Fragrance-free and vegan to reduce potential irritants
• Includes soothing Centella derivatives to ease sensitivity
• Start slowly (every other day) if you have very reactive skin

How quickly will I see changes and how should I pair it with other products?

Visible improvements in clarity and redness were observed in study participants after two weeks, though results vary by individual. For balanced day-and-night care, use this 10% serum in the morning as a non-pilling base and complement with a stronger nighttime treatment if needed.

• Clinical study reported measurable clarity and redness improvement at 2 weeks
• Recommended AM use; always follow with SPF in the morning
• Pair with JUMISO 20% Niacinamide Serum at night for intensified results
• Apply 2–3 drops; avoid mixing with strong actives without patch testing

Who is this for? This serum is aimed at anyone wanting a practical, non-sticky brightening step in their morning routine: people dealing with dark spots, uneven tone, post-blemish marks, mild redness, or those new to niacinamide who need a gentle, fast-absorbing formula. It’s also well suited to users who need a reliable makeup base that won’t pill under sunscreen or foundation. As always, patch test if you have a history of sensitivities or use multiple actives.
