The Ordinary Niacinamide 10% + Zinc 1% is a water-based serum formulated to address the appearance of blemishes, congestion, and uneven skin texture. This product combines two well-known active ingredients: niacinamide, a form of vitamin B3, and zinc PCA, a mineral salt. The serum is designed for daily use on blemish-prone skin, focusing on balancing sebum production and supporting a smoother skin surface.

Niacinamide at a 10% concentration helps to visibly regulate oil activity and minimize the appearance of enlarged pores, while also contributing to a more even skin tone over time. The addition of zinc PCA at 1% works in conjunction with niacinamide to further support pore clarity and reduce the look of excess shine. This formula is water-based, lightweight, and absorbs quickly without leaving a greasy residue, making it suitable for combination to oily skin types.

The serum is free from oil, alcohol, and fragrances, which helps reduce the risk of irritation for sensitive or reactive skin. It fits into a simple skincare routine, typically applied after toning and before moisturizing. As with all The Ordinary products, the pricing remains accessible, offering a straightforward solution without unnecessary additives. The packaging is minimal and functional, emphasizing the brand’s focus on efficacy over aesthetics.

Users are advised to perform a patch test before first use and to introduce the product gradually if new to active ingredients. Because individual skin responses may vary, consistent application over several weeks is recommended to assess visible changes in texture and clarity. This serum is not intended to treat medical conditions, but rather to support the daily management of blemish-prone skin through targeted ingredient levels.
