Azelaic Acid (Cosmetic Grade)

Azelaic Acid (Cosmetic Grade) is one of the most versatile and dermatologist-loved skincare actives. Let’s break it down clearly:

🔹 Azelaic Acid

• A naturally occurring dicarboxylic acid found in grains (barley, wheat, rye) and produced by yeast that lives on normal skin.
• For cosmetics, it’s usually lab-synthesized for purity and stability.
• Appears as a white crystalline powder.
• Widely used in dermatology and skincare formulations for acne, pigmentation, and rosacea.

🔹 Key Properties & Benefits

1. Anti-Acne

• Antibacterial → kills acne-causing bacteria (Cutibacterium acnes).
• Keratin-regulating → prevents clogged pores & blackheads.
• Reduces inflammation → calms red, angry breakouts.

2. Brightening & Pigmentation Control

• Inhibits tyrosinase, the enzyme that makes melanin (skin pigment).
• Helps fade dark spots, melasma, and post-acne marks.

3. Rosacea & Sensitive Skin

• Anti-inflammatory → reduces redness and swelling.
• Less irritating than many other actives (like retinoids or high-strength AHAs).

4. Anti-Aging Support

• Promotes cell turnover → smoother, more even-toned skin.
• Protects against free radical damage.

🔹 Cosmetic & Skincare Uses

• Serums & creams → for acne, pigmentation, and redness.
• Spot treatments → to target stubborn blemishes or dark spots.
• Brightening masks → combined with niacinamide or vitamin C.
• Gentle exfoliants → as an alternative to stronger acids.

🔹 Usage Guidelines

• Typical cosmetic concentration: 5% – 10% (gentle, OTC cosmetic level).
• Medical/dermatological formulations: up to 20% (prescription strength).
• Solubility: poorly water-soluble → usually suspended in emulsions, creams, or gels.
• Works well with niacinamide, hyaluronic acid, and antioxidants.
• Avoid layering with strong acids (AHA, BHA) or high-strength retinoids in the same routine (can irritate).

🔹 Safety & Considerations

• Generally safe for all skin types, even sensitive.
• Mild tingling or dryness may occur at first use.
• Always recommend a patch test.
• Pregnancy-safe (often recommended by dermatologists for acne/melasma during pregnancy).

🔹 Storage

• Store in a cool, dry place, away from direct light.
• Keep the container airtight to prevent degradation.
