Niacinamide (Vitamin B3) Powder

Niacinamide, also known as Vitamin B3, is one of the most well-researched actives in modern skincare science. It works by supporting the skin's natural barrier, regulating sebum production, and inhibiting the transfer of melanin to skin cells — which is why it's a go-to ingredient for formulators targeting uneven tone, enlarged pores, and sensitivity.

What It Does in a Formula

• Brightening: Reduces the appearance of dark spots and hyperpigmentation by interrupting melanin transfer at the cellular level
• Pore-refining: Regulates sebum and visibly minimizes pore size with consistent use
• Barrier support: Boosts ceramide synthesis, strengthening the skin's moisture barrier
• Anti-inflammatory: Calms redness and irritation, making it suitable for sensitive and acne-prone skin types
• Antioxidant activity: Helps protect skin cells from oxidative stress

Formulation Guidelines

• Use level: 2–10% — start at 2–5% for general use; 5–10% for targeted brightening or pore-refining formulas
• Phase: Water phase — dissolve at room temperature or below 40°C
• pH range: Most effective and stable between pH 5.5–7.5
• Compatible with: Hyaluronic acid, peptides, AHAs, BHAs, retinoids, and most antioxidants
• Note: At concentrations above 5%, a small percentage of users may experience temporary flushing. This is a known reaction and not harmful, but worth noting in your product documentation.
