Vitamin B3 (Niacinamide)

Niacinamide, also known as vitamin B3, is a versatile, water-soluble active widely used in cosmetic formulations for its barrier-supportive, brightening, and complexion-balancing benefits. It helps strengthen the skin’s moisture barrier by supporting ceramide production, improving hydration and reducing the look of dryness and sensitivity over time. Niacinamide is also valued for helping visibly refine pores, regulate the appearance of excess oil, and improve the look of uneven tone, dullness, and post-blemish marks, promoting a clearer, more even-looking complexion. With additional antioxidant-supportive and soothing properties, it is well-suited to anti-aging, clarifying, and “radiance” concepts across many skin types, including sensitive and blemish-prone. Commonly found in serums, moisturizers, toners, masks, eye products, and targeted treatments, Niacinamide is typically used at low to moderate levels and formulated with attention to pH and overall system compatibility for optimal tolerance and performance.
