Jumiso Niacinamide 10% Serum 40ml

10% Niacinamide Targets Sebum, Pores, and Tone All at Once

A high-potency serum that addresses excess sebum, enlarged pores, and dull skin tone in one bottle. Formulated with 10% niacinamide, a vitamin B3 derivative, it helps regulate sebum production and inhibits melanin synthesis to target hyperpigmentation such as dark spots and melasma. The watery texture absorbs quickly without any sticky residue, even at this concentration, and the formula is free from artificial colorants and fragrances, making it gentle enough for sensitive skin.

Visible Improvements After 2 Weeks of Use

In a clinical study with 20 participants, the following improvements were observed after 2 weeks of use.

• 47.9% improvement in sebum (oil)
• 23.49% improvement in temporary pore area
• Visible improvement in dark spots and melasma within the skin

Completed sensitive skin irritation testing, making it suitable for daily morning and evening use.

Brightening Complex and Pore-Refining Actives

Beyond niacinamide, the formula includes tranexamic acid (targets dark spots and melasma), and glutathione (inhibits melanin production) to help even out skin tone. Zinc PCA and lemon myrtle leaf extract control excess sebum, while succinic acid smooths uneven texture. Recommended for those with visible pores due to excess sebum production, or anyone looking to improve overall skin tone and texture. When using in the morning, always finish with a sunscreen of SPF 30 or higher.

After toner, before essence and cream

Use your niacinamide serum right after toner, once your skin texture is prepped and balanced. Let the serum absorb fully, then seal it in with your moisturizer or cream so the active ingredients can work their way into skin. If you're layering multiple treatment serums, go from lightest to richest: watery serum → essence → cream.

Morning and evening use

Designed for daily care, this serum fits seamlessly into both your AM and PM routines. If you apply it in the morning, always follow with SPF 30 or higher to protect the efficacy of the niacinamide and shield your skin throughout the day.

Dispense sparingly and press in gently

Thanks to its watery texture, 2–3 drops are enough to cover your entire face. Warm the serum between your palms, dot it onto both cheeks, forehead, and chin, then smooth outward from the center of your face. Finish by gently pressing your palms over your skin to help it sink in without any sticky residue.

Pairing by skin concern

• For excess sebum and visible pores, layer this serum over a lightweight hydrating toner, then lock it in with an oil-free moisture gel.
• For dull complexion and dark spots, alternate with a vitamin C serum by time of day. Try vitamin C in the morning and niacinamide at night to support your brightening routine.
• For refining skin texture, use a gentle exfoliator 1–2 times a week, then maintain that smoothness with this serum daily.

Storage and usage notes

This formula is free from artificial colorants, so prolonged exposure to heat or direct sunlight may cause the color to fade slightly — but the quality remains unaffected. If you notice white powder around the bottle opening, that's a natural occurrence with high-concentration formulas and nothing to worry about. Because this is a potent niacinamide serum, those with sensitive skin may want to start by using it only in the evening and monitor how their skin responds.
