★What are the safe and compliant concentration limits of Azelaic Acid Powder for cosmetic products?
EU: Up to 10% concentration is allowed for cosmetic products; concentrations exceeding 10% are classified as medicinal products and require drug licensing.
USA (FDA): Up to 10% for over-the-counter cosmetic products; 15%-20% concentrations are classified as prescription-only for treating acne and rosacea.
China, South Korea, Japan: Typically 1%-10% for cosmetic formulations, aligned with global cosmetic safety standards and local regulations.
★What cosmetic formulations are suitable for adding Azelaic Acid Powder?
Serums (water-based or oil-based): Use solubilizers like PEG-400 or propylene glycol to ensure even dispersion and clarity; ideal for brightening and acne-prone skin lines.
Creams & Lotions: Disperse Azelaic Acid in polar ester oils (e.g., caprylic/capric triglyceride, isononyl isononanoate) instead of ordinary mineral oil or silicone oil to avoid precipitation and ensure stability.
Gels: Create suspensions to evenly disperse Azelaic Acid, suitable for targeted acne treatment (e.g., spot treatments).
Sensitive Skin Products: Formulate with mild excipients (e.g., panthenol, hyaluronic acid, ceramides) to enhance skin compatibility, as Azelaic Acid itself is low-irritation and suitable for sensitive skin types.
★What ingredients can Azelaic Acid Powder be combined with?
Niacinamide
It strengthens the skin barrier, reduces redness and inflammation, and amplifies azelaic acid’s brightening and anti-acne effects while lowering irritation risk.
Hyaluronic Acid

Salicylic Acid (BHA)
Unclogs pores, exfoliates dead skin efficiently, and jointly fights inflammatory acne, blackheads and comedones.
Panthenol (Vitamin B5)
Soothes irritation, repairs damaged skin barrier, and improves tolerance to azelaic acid.
Tranexamic Acid
