Azelaic acid

Azelaic acid is a clinically proven, multitasking active widely used in dermatology and cosmetics for brightening, acne control, and reducing inflammation. Naturally derived from grains such as barley and wheat and produced by Malassezia yeast on the skin, it is both biocompatible and highly effective.

Key Cosmetic and Dermatological Benefits

1. Anti-acne / Sebum Control: Antibacterial against Cutibacterium acnes and Staphylococcus epidermidis. Reduces keratin buildup, preventing clogged pores and comedones.

2. Brightening & Anti-pigmentation: Inhibits tyrosinase, reducing melanin production. Gradually fades melasma, dark spots, and post-acne marks.

3. Anti-inflammatory: Calms redness and irritation, effective for rosacea-prone or sensitive skin.

4. Texture Refinement: Smooths skin and improves clarity without harsh exfoliation.

   Formulation Guidelines
   Typical Use Level: 5–10% (cosmetic); 15–20% (dermatological)
   Solubility: Insoluble in water; soluble in glycols (e.g., propylene glycol, butylene glycol)
   Phase: Dissolve in glycol phase before emulsification
   pH Range: 4.0–5.5 (optimal balance between activity and stability)
   Texture: Best suited for creams or gels (not watery serums)
   Compatibility: Works well with niacinamide, panthenol, allantoin, and salicylic acid (in low concentrations)
   Avoid Mixing With: Strong acids (like glycolic or lactic acid above 5%) — may destabilize or irritate skin.
   Safety Profile
   Non-toxic and non-comedogenic. May cause mild tingling or dryness at higher concentrations. Patch testing is recommended for sensitive skin.
