The JUMISO Niacinamide 20 Serum is a high-potency brightening and pore-refining formula that combines 20% niacinamide with tranexamic acid, glutathione, and a Triple Centella Complex to fade pigmentation, regulate excess oil, and calm redness. Its lightweight, water-gel texture absorbs rapidly without stickiness, making it suitable even for sensitive and acne-prone skin seeking a brighter, clearer tone. This serum is also enriched with multiple humectants and soothing botanicals like centella, ivy leaf, peony root, and portulaca, which help support barrier repair and reduce irritation during use.
