The Ordinary Azelaic Acid Suspension 10%

What is in the formula

This product contains 10% azelaic acid in a cream-like suspension. Dimethicone and other silicone ingredients appear in the formula. The US brand page offers 30 ml and 100 ml sizes. Its uneven-tone positioning does not turn it into a diagnosis or a prescription treatment.

Evidence and its limits

A double-blind study in 329 women with melasma compared 20% azelaic acid cream and 4% hydroquinone over 24 weeks, with broad-spectrum sunscreen. That is a different concentration, vehicle and clinical setting from this 10% suspension used for post-breakout marks. The trial cannot establish equivalent results, a success rate or a promised timeline for this product.

Fit in the current routine

The current finder selects it only when the approved post-breakout route and treatment safeguards allow an optional active. It is a single treatment choice, not an extra layer automatically added to vitamin C. The review does not change the finder’s eligibility or high-sun-exposure hold.

What this review cannot establish

Silicone content is a formula observation; we have not tested its feel, pilling or compatibility with a particular sunscreen. This review makes no claim to treat acne, rosacea or melasma and does not equate a cosmetic 10% formula with prescription strengths.

Directions and precautions

The brand advises use on unbroken skin, avoiding eyes and mouth, patch testing and daytime sun protection. If irritation develops, follow its stop-use guidance. Its pairing list advises against combinations including direct acids, direct vitamin C and retinoids; consult the full current brand guidance before combining products.

Always check the current package. A review cannot assess your individual reaction or replace care from a qualified clinician.
