The Jumiso Niacinamide 20 Serum is a high-potency, clinical-grade brightening treatment formulated to fade stubborn hyperpigmentation, minimize enlarged “orange peel” pores, and control excess sebum production. Despite its intensive 20% Niacinamide concentration, the serum is uniquely engineered with a specialized stabilization system that completely dissolves the active powder to prevent recrystallization, yielding a zero-irritation index in dermatological patch tests. It features a lightweight, fast-absorbing, and non-sticky texture that leaves a smooth, balanced finish.
