What Is Niacinamide?
Niacinamide is the active form of Vitamin B3, a water-soluble nutrient your skin uses to support its own repair processes. In skincare, it's valued for being genuinely multi-tasking: it supports the skin barrier, helps regulate oil production, and visibly improves the look of uneven tone and enlarged pores.
Because it's naturally occurring in skin cells, niacinamide is generally very well tolerated, which is why it appears across ASI's hydration-focused formulas rather than being reserved for a single targeted treatment.
