The Ordinary Niacinamide 10% + Zinc 1% Smoothing Serum

Improve the appearance of oily, congested and uneven-looking skin with The Ordinary Niacinamide 10% + Zinc 1% Serum. This lightweight, water-based formula is designed to support smoother, brighter and more balanced-looking skin. The formula combines a high 10% concentration of niacinamide, also known as vitamin B3, with 1% zinc PCA. Niacinamide helps improve the appearance of enlarged pores, uneven texture and dullness while supporting the skin’s natural moisture barrier. Zinc PCA helps balance visible shine and excess sebum. Suitable for blemish-prone skin, the serum helps reduce signs of congestion without using abrasive exfoliating particles. Its lightweight texture layers easily with other water-based skincare products and can be used in both morning and evening routines. Apply a few drops to the face after cleansing and before heavier moisturizers, creams or oils. Use only on unbroken skin and patch test before regular application. The Ordinary recommends using direct or indirect vitamin C products in a separate routine.
