Azelaic Acid competitively inhibits tyrosinase activity, effectively reducing melanin production and providing significant whitening and spot-fading effects. Its unique mechanism targets hyperpigmentation at the cellular level without causing skin irritation.
Works through multiple pathways: reduces filamentous keratin synthesis, prevents follicular hyperkeratinization, inhibits reactive oxygen species, provides anti-inflammatory benefits, and directly kills surface and follicular bacteria including P. acnes.
Our specialized milling process ensures 95% of particles pass 5μm, providing superior skin penetration, even distribution in formulations, and enhanced bioavailability compared to standard azelaic acid powders.
Beyond its primary functions, azelaic acid improves skin moisturizing capacity and elasticity, making it suitable for sensitive skin and long-term use in daily skincare regimens.
Azelaic Acid has limited solubility in water (approximately 2.4 g/L at 20°C) but is soluble in alcohol and other organic solvents. Determine optimal solvent system based on your formulation requirements.
Recommended usage levels: 0.1-20.0% depending on application. For cosmetic products, 5-15% is typical; for pharmaceutical applications, up to 20% may be used under medical guidance.
Formulate within pH range 4.0-6.0 for optimal stability and efficacy. The compound maintains activity across this range while being compatible with skin physiology.
Utilize the ultrafine particle size for easy dispersion. Incorporate during water phase with adequate mixing to ensure homogeneous distribution throughout the formulation.
Test compatibility with other active ingredients, particularly when combining with Natural Antioxidants or other brightening agents for synergistic effects.
Whitening Products: Creams, serums, and essences targeting melasma, post-inflammatory hyperpigmentation, age spots, and uneven skin tone. Effective for all skin types including sensitive skin.
Acne Treatments: Face washes, spot treatments, and leave-on products for mild to moderate acne. Helps control sebum production and prevent future breakouts.
Multi-functional Formulations: Combined treatments addressing both acne and hyperpigmentation concerns in single products.
Used in prescription and OTC topical preparations for acne vulgaris, rosacea, and hyperpigmentation disorders. Clinical studies support its efficacy at concentrations of 15-20% for various dermatological conditions.
Ideal for clinical skincare formulations, professional peels, and dermatological preparations where controlled concentration and purity are essential for treatment efficacy and safety.
