Azelaic acid occurs naturally in animal products and whole grain cereals. It is said to help the skin renew itself rapidly and stops cell buildup that causes clogged pores. Hence, azelaic acid is used in the treatment of acne for it can reduce the formation of blackheads and zits and kill P.acnes bacteria, which causes inflammatory acne. Azelaic acid belongs to the dicarboxylic acid group of medications.
How should Azelaic Acid be used?
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. Use azelaic acid carefully, following instructions printed on the label and getting further clarifications if needed from your doctor or pharmacist. The full benefits can be realized only after at least 4 weeks or more of applications.
The affected areas must be washed and cleansed with mild soap or cleansing lotion and patted dry gently using a soft towel. 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.

Azelaic acid for acne is as effective as other topical creams like tretinoin, topical antibiotics and benzoyl peroxide in treating acne. It is beneficial in treating mild or moderate acne outbreaks by reducing the P.acnes bacteria that attack the skin, keeping pores unclogged and therefore reducing acne outbreaks. Azelaic acid is also said to help in treating dark spots that some patients develop due to the color of their skin. Most people are able to tolerate this medication, even with prolonged use and hence it is widely prescribed as a topical treatment for acne.
