Azelaic acid for acne is usually used as a topical cream under the brand name ‘Azelex’. ‘Azelex’ cream contains 20% of this azelaic acid.   As a topical gel / jelly or cream, azelaic acid clears lesions, swelling and bumps caused by acne and acne rosacea. The gel or cream is applied directly to affected areas twice a day. For best results, try and apply the medications at the same time every morning and evening.

The full benefits can be realized only after at least 4 weeks or more of applications.

Always avoid cleansers or soaps that contain harsh chemicals, alcohol, tinctures, and astringents, peeling agents or abrasive products. Once cleaned, apply a thin layer of the gel or cream and massage it into the skin. Try not to get the cream into your eyes, mouth or nose and if you do so, wash thoroughly. Bandages or other dressings need not be used and non-comedogenic makeup can be used after the medication has been completely absorbed. Wash your hands thoroughly after each application.
