The Ordinary Niacinamide 10% + Zinc 1%

The Ordinary Niacinamide 10% + Zinc 1% is one of the brand’s best-known serums, pairing a high 10% concentration of niacinamide (vitamin B3) with zinc PCA in a lightweight, water-based formula. Together they help balance visible oiliness, reduce the look of blemishes and enlarged pores, and improve overall skin clarity and texture for a smoother, more even-looking complexion. It suits oily, combination and blemish-prone skin, and is a practical daily step for anyone struggling with shine in warm, humid weather. Apply a few drops to the face morning and evening after cleansing and before heavier creams. Avoid using in the same routine as vitamin C (L-ascorbic acid). If you notice tingling or redness, reduce frequency; patch test before first use and avoid the eyes. Order at Reginah.com for 24-hour delivery.
