The Ordinary Niacinamide 10% + Zinc 1%

The Ordinary Niacinamide 10% + Zinc 1% has become a skincare phenomenon, and for good reason. This high-strength vitamin B3 serum targets blemishes, enlarged pores, and uneven skin tone at an incredibly accessible price point. The 10% niacinamide concentration is clinically proven to reduce sebum production and minimize the appearance of pores, while zinc PCA helps regulate oil and calm inflammation. The lightweight, water-based serum absorbs quickly without leaving a sticky residue. Within a few weeks of consistent use, many users notice reduced breakouts, smaller-looking pores, and a more balanced complexion. However, the high concentration can be irritating for sensitive skin, especially when first introduced. The formula can also pill when layered with certain products, particularly silicone-based primers or vitamin C serums. For best results, start slowly (every other day) and apply to clean, dry skin before heavier serums and moisturizers. Despite these minor drawbacks, the incredible value and proven results make this a staple for oily and acne-prone skin.
