Niacinamide

• Other names: Vitamin B3 ; nicotinamide
  It is one of the most research-backed, multitasking actives in skincare and hair care.
  It supports barrier repair, oil balance, brightening, and anti-aging, and is suitable for all skin types, even sensitive skin.
• INCI name: Niacinamide
• Appearance: White, crystalline powder
• Solubility: Freely soluble in water, glycerin, and ethanol
• pH stability: Best between 5.0–7.0
• Heat stability: Good; therefore avoid prolonged heating above 70 °C

Key Cosmetic Functions

1. Barrier Repair: Stimulates ceramide and free fatty acid synthesis, strengthening the skin’s natural barrier. Reduces transepidermal water loss (TEWL).

2. Brightening & Even Skin Tone: Inhibits melanosome transfer from melanocytes to keratinocytes → fades dark spots and hyperpigmentation.

3. Sebum Regulation: Helps control excess oil production — ideal for oily and acne-prone skin.

4. Anti-aging & Firmness: Boosts collagen production and reduces fine lines.

5. Soothing & Anti-inflammatory: Calms redness, irritation, and supports sensitive skin (rosacea, acne).

6. Antioxidant Protection: Protects against oxidative stress and blue-light damage.

Formulation Guidelines

• Typical use level: 2–5% (up to 10% in clinical formulas)

• Phase :Add to heated water phase
• pH range: 5.0–7.0 (best stability and skin compatibility)
• Compatibility: Works well with panthenol, allantoin, glycerin, hyaluronic acid, zinc PCA
• Avoid Very low pH (below 4.5) — can convert it to niacin, causing redness (“niacin flush”)
