JUMISO 10% Niacinamide Dark Spot Serum — TXA + Glutathione, 1.35 fl oz Water-Gel for Even Tone & No-Pill Layering

JUMISO 10% Niacinamide Dark Spot Serum is a lightweight water-gel that combines 10% niacinamide with tranexamic acid and glutathione to help even skin tone and reduce the appearance of dark spots while layering smoothly under makeup.

This serum blends a clinically studied 10% niacinamide concentration with tranexamic acid (TXA) and antioxidant glutathione in a quick-absorbing, non-sticky water-gel. Formulated with hyaluronic acid for hydration and a Triple Centella Complex to soothe, the texture is designed to avoid pilling so it can be worn under sunscreen and makeup every morning. It’s 100% vegan, cruelty-free, fragrance-free, and made in Korea—intended as a daily brightening step suitable for beginners and sensitive skin.

How does this serum help reduce dark spots and uneven tone?

The formula targets multiple pathways that contribute to discoloration: niacinamide helps regulate pigment transfer, TXA addresses persistent hyperpigmentation mechanisms, and glutathione offers antioxidant support to brighten the complexion. Using them together offers broader action than a single-ingredient product.

• 10% niacinamide to visibly improve skin clarity and tone.
• Tranexamic acid to reduce the look of stubborn dark marks.
• Glutathione acts as an antioxidant to support brighter-looking skin.
• Hyaluronic acid for lightweight hydration and smoother texture.

Will this serum pill under sunscreen or makeup?

No—its water-gel vehicle is formulated to absorb quickly without tackiness or gluey residue. That means it layers well under SPF, foundation, and primer without flaking or balling up, creating a smooth base for morning routines.

• Fast-absorbing water-gel texture reduces stickiness.
• Designed specifically to prevent pilling under other products.
• Leaves a dewy, non-greasy finish ideal for makeup application.

How gentle is this for beginners and sensitive skin?

Even at a 10% niacinamide strength, the serum is formulated to be beginner-friendly and calming. The Triple Centella Complex (Asiaticoside, Madecassic Acid, Asiatic Acid) soothes the appearance of redness and supports barrier comfort, making it appropriate for those who experienced irritation with stronger actives.

• Centella extracts to calm visible redness and sensitivity.
• Fragrance-free and moderate active concentration for gradual results.
• Clinical-use feedback showed measurable clarity and redness improvements.

How and when should I use this serum in my routine?

Use 2–3 drops after cleansing in the morning and evening. In the AM, follow with a moisturizer and broad-spectrum SPF; the lightweight formula is ideal under makeup. For more intensive night-time brightening, pair mornings with this 10% formula and a higher-concentration niacinamide serum at night as recommended by the brand.

• Apply 2–3 drops to clean skin AM and PM.
• Always follow with sunscreen in the morning.
• Layer under foundation or moisturizer without pilling.

Who is this for: This serum is aimed at anyone seeking an effective, easy-to-layer brightening step—beginners to niacinamide, people with post-acne marks or uneven tone, and those who need a non-pilling base for makeup. It’s also suitable for sensitive skin types looking for a gentle, multi-ingredient approach to dark spot care without fragrance or heavy oils.
