Jumiso Niacinamide 10% Serum 40ml

10% Niacinamide targets excess sebum and visible pores

If excess oil and enlarged pores are your main concerns, this serum deserves your attention. Formulated with 10% niacinamide, it's a brightening functional cosmetic that controls shine while visibly refining pores. The lightweight, watery texture absorbs quickly without any sticky residue, making it easy to layer morning and night. Free from artificial fragrance and colorants, it's gentle enough for sensitive skin.

Clinically proven sebum and pore improvement in just 2 weeks

The results from human application testing speak for themselves.

• 47.9% improvement in sebum (oil)
• 23.4% reduction in temporary pore area
• 19.9% improvement in surface-level dark spots and hyperpigmentation
• 25.8% improvement in deeper dark spots and hyperpigmentation

Skin redness caused by external irritation was calmed by 72.5% after just one use. It has also completed a sensitivity test on sensitive skin, so you can use it with confidence.

A complete formula from brightening to soothing

Beyond niacinamide (sebum control and tone evening), the formula includes tranexamic acid (targets dark spots and hyperpigmentation) and glutathione (inhibits melanin production) to help clarify and brighten the complexion. Zinc PCA and lemon myrtle leaf extract regulate sebum, while succinic acid smooths uneven texture. Centella-derived TECA and triple hyaluronic acid soothe irritated skin while delivering a surge of hydration. Ideal for anyone looking to address excess sebum, visible pores, and a dull complexion all at once.

Use after toner, during the essence or serum step

After cleansing and toning, apply while skin is still slightly damp. With 10% niacinamide, this functional serum works best at the essence stage to help your moisturizer absorb more effectively. If layering with other serums, apply from lightest to richest texture.

A daily serum you can use morning and night

The watery texture makes it easy to use twice a day without feeling heavy. When applying in the morning, always follow with SPF 30 or higher to help prevent UV-induced hyperpigmentation. At night, it works with your skin's natural renewal cycle to help control sebum and support tone-evening.

Apply 2–3 drops and gently press into skin

Dispense 2–3 drops with the dropper and dot onto your forehead, both cheeks, nose, and chin. Use your fingertips to gently press and smooth outward from the center of your face. For areas where pores or excess oil are a concern, like the T-zone, feel free to apply a second layer. It absorbs quickly with a fresh, non-sticky finish, so you can move on to the next step right away.

Recommended pairings by skin concern

• Pores and oil control: Follow a lightweight hydrating toner with this serum, then seal with a low-oil moisture gel
• Dull complexion: Alternate with a vitamin C serum at different times of day to boost brightening results
• Sensitivity from external irritants: The TECA helps soothe, so try pairing with a centella cream

Storage and usage notes

This formula is free from artificial colorants, so prolonged exposure to heat or light may cause slight fading — but quality and efficacy remain unaffected. If you notice white residue around the bottle opening, that's a natural occurrence with high-concentration actives and nothing to worry about. Store in a cool place away from direct sunlight. If redness, itching, or irritation occurs during use, discontinue and consult a dermatologist.
