Niacinamide

Niacinamide is amide derivative of vitamin B3, acting on multi‑layers of skin tissue. It promotes skin lipid‑barrier synthesis, regulates sebum secretion, refines visually enlarged pores, lightens post‑inflammatory pigment marks and improves sallow dull complexion. It helps smooth uneven skin surface texture.

It shows outstanding synergistic effect when compounded with Alpha‑Arbutin, Beta‑Arbutin, Tranexamic Acid, Centella Asiatica Extract and VC‑derivatives for multi‑functional brightening & barrier‑repair compound formulas. Suitable for normal, oily and combination skin types. Avoid extremely low‑pH environment to reduce nicotinic‑acid‑related irritation risk.

• Reinforce skin barrier: boost lipid synthesis, lower transepidermal water‑loss.
• Improve dull & sallow complexion: ameliorate tired yellowish skin tone.
• Sebum‑regulating: balance oily‑skin secretion, visually refine enlarged pores.
• Fade post‑inflammatory marks: lighten acne‑caused hyperpigmentation spots.
• Wide formula compatibility: water‑soluble, match most aqueous cosmetic actives.
• Multi‑benefit mild active, fit daily long‑term skincare for diverse skin types.

Formulation Tip: Recommended cosmetic adding‑amount 2‑5%. Avoid long‑term extremely low‑pH condition to prevent nicotinic‑acid generation. Keep sealed dry storage, guard against moisture‑caking.

Full Manufacturing Steps

1. High‑grade pyridine‑series raw‑material screening, strict impurity monitoring.
2. Amidation directional chemical synthesis reaction for target niacinamide molecule.
3. Multi‑step intermediate purification, remove nicotinic‑acid residual and reaction by‑products.
4. Multi‑times recrystallization refining, strictly control nicotinic‑acid ≤0.1%.
5. Filtration & vacuum low‑temperature drying to get uniform white crystal powder.
6. HPLC full‑item detection: main‑body purity and nicotinic‑acid impurity index.
7. Comprehensive quality inspection & moisture‑proof sealed packaging with unique batch‑code./li>
