Detailed answer

To use azelaic acid for acne scars, start by cleansing the skin and patting it dry. Then, apply a thin layer of azelaic acid gel or cream to the affected areas of the skin once or twice daily, as directed by your dermatologist. Gently massage the product into the skin until it is fully absorbed. It is important to avoid applying azelaic acid to broken or irritated skin. Follow up with a moisturizer and sunscreen during the day, as azelaic acid can make the skin more sensitive to the sun. Consistent use of azelaic acid over a period of several weeks or months can help improve the appearance of acne scars by reducing inflammation, promoting cell turnover, and inhibiting the production of excess melanin.
