The Niacinamide 10% + Zinc 1% serum by The Ordinary is a skincare solution formulated to improve skin texture and tone. This lightweight, fast-absorbing serum features a high concentration of Niacinamide (Vitamin B3) to help regulate sebum production and reduce skin shine. The inclusion of 1% Zinc helps minimize the appearance of enlarged pores and addresses skin blemishes. Designed for daily use, this product is suitable for various skin types, including sensitive skin. To apply, place a few drops onto clean, dry skin once or twice daily, avoiding the eye and mouth areas. As Niacinamide can increase sensitivity to sunlight, it is recommended to use sunscreen during the day. This serum is available in a 30ml size and serves as a functional addition to a regular skincare routine for those managing oily or uneven skin.
