About azelaic acid

Azelaic acid is a naturally occurring dicarboxylic acid found in grains like wheat and barley. In dermatology, it’s formulated into creams and gels at concentrations of 15-20% for topical use. Unlike harsher treatments like retinoids or benzoyl peroxide, azelaic acid is gentle, making it suitable for sensitive, rosacea-prone, or darker skin tones.

It exhibits multiple mechanisms: antimicrobial action against Propionibacterium acnes (now Cutibacterium acnes), anti-inflammatory effects by neutralizing free radicals and inhibiting reactive oxygen species (ROS), and tyrosinase inhibition to reduce melanin production and hyperpigmentation. Clinical studies confirm its efficacy in acne vulgaris, papulopustular rosacea, melasma, and even emerging uses like hidradenitis suppurativa and keratosis pilaris.

Key benefits

• Antibacterial: Kills acne bacteria and limits their growth (bacteriostatic and bactericidal).
• Anti-keratinizing: Reduces excess keratin to prevent pore blockages and blackheads.
• Anti-inflammatory: Soothes redness, calms irritation in rosacea, and counters free radicals.
• Depigmenting: Evens skin tone by inhibiting tyrosinase, effective for post-acne marks, melasma, and dark spots.
• Antioxidant: Protects skin from oxidative damage.

Before using azelaic acid

Allergy

Do not use if allergic to azelaic acid or any ingredients in Finacea or Skinoren. Signs of allergy include rash, itching, swelling, or breathing difficulties—seek immediate medical help.

Pregnancy and breastfeeding

Azelaic acid is generally considered safe during pregnancy (Category B) and breastfeeding, with minimal systemic absorption. Consult your doctor before use.

Other medicines

Compatible with most topicals, but avoid combining with strong exfoliants or irritants initially to prevent dryness. Can be used alongside oral antibiotics or hormonal therapies for acne.

How to use azelaic acid

Apply thinly to clean, dry affected areas (face, chest, back) twice daily—morning and evening. Use a pea-sized amount for the face, gently massaging in. Wash hands after application. Cosmetics can be applied after it dries (15-30 minutes).

Improvement in acne may take 4 weeks; full effects in 2-3 months. For rosacea, redness reduces within weeks.

Brands available

• Skinoren 20% Cream: For mild-moderate acne, reduces bacteria, keratin, inflammation, and pigmentation.
• Finacea 15% Gel/Foam: Licensed for rosacea, also used off-label for acne.
• Generics: Available as azelaic acid 15-20% formulations.

Cautions

• Avoid eyes, mouth, mucous membranes—rinse if contact occurs.
• May bleach hair or fabrics; use white towels.
• Not for severe acne or nodules—see a dermatologist.
• Sun protection recommended as it may increase sensitivity.
• Patch test first for sensitive skin.

Side-effects of azelaic acid

Commonly causes mild burning, stinging, itching, dryness, or redness (affects 10-50% initially), resolving in 1-2 weeks as skin adjusts. Rare: severe irritation, allergic reactions, worsening acne (discontinue and consult doctor).

• Mild (transient): Prickling, scaling, erythema.
• Rare: Contact dermatitis, hypopigmentation (temporary lightening, more in dark skin).

No systemic side effects due to low absorption.

If you take too much (overdose)

Overapplication causes excessive local irritation. Rinse with water; symptoms resolve quickly. Seek medical advice if persistent.

Stop taking azelaic acid and tell a doctor

• Signs of allergy: hives, swelling, anaphylaxis.
• Severe irritation or ulceration.
• No improvement after 1 month or worsening.
• Pregnancy/breastfeeding concerns.

Expiry, storage, and disposal

Store below 25-30°C, away from children. Discard after expiry; do not flush—use medicine take-back programs.

How to dispose of azelaic acid safely

Return unused portions to pharmacy or local take-back schemes to prevent environmental contamination.
