Jumiso Niacinamide 20% Serum 40ml — Maximum Strength Pore and Sebum Control
TheJumiso Niacinamide 20% Serum 40ml is a powerful, focused treatment aimed at transforming congested, oily, and textured skin.3 From the effective K-Beauty brand Jumiso, this serum moves beyond standard formulas to deliver the maximal benefits of Niacinamide for those who need intensive correction.
Niacinamide (Vitamin B3) at a 20% concentration is the hero ingredient.4 This high percentage provides enhanced efficacy compared to lower concentrations, making it exceptionally effective for:
Pore Minimization: It helps normalize the lining of the pore, preventing oil and debris buildup, leading to a visible shrinking of enlarged pores over time.5
Sebum Regulation: It significantly decreases the rate of sebum excretion, minimizing shine and reducing the likelihood of breakouts and blackheads.6
Brightening: It interrupts the process that leads to hyperpigmentation, successfully fading stubborn dark spots and post-acne marks (PIH).7
The formula is further strengthened by Zinc PCA, which offers powerful antibacterial and oil-regulating properties, and Arbutin, which synergizes with Niacinamide to provide a comprehensive attack on dark spots and uneven tone. The lightweight, slightly viscous texture absorbs quickly, delivering these high-potency actives precisely where they are needed without clogging the skin.
Key Benefits
Maximum Potency: Features 20% Niacinamide for targeted, fast-acting results on pores and oil production.
Visibly Shrinks Pores: Helps to refine the appearance of enlarged and stretched pores.
Controls Oil & Acne: Zinc PCA helps regulate sebum and offers antibacterial benefits to calm breakouts.
Fades Dark Spots: Excellent for treating hyperpigmentation, sun damage, and post-acne scarring.
