The Ordinary Niacinamide 10% + Zinc 1% is a potent serum designed to control excess oil production and target blemishes for those with acne-prone skin. Formulated with a high concentration of niacinamide (vitamin B3) and zinc, this serum works synergistically to regulate sebum production, reduce inflammation, and minimize the appearance of pores. Niacinamide helps to improve the skin's barrier function, enhance moisture retention, and brighten the complexion, while zinc aids in calming irritated skin and promoting healing. The lightweight, non-greasy texture of the serum absorbs quickly into the skin, leaving it feeling balanced and refreshed.
