Hi Dear , .As per your query you have problem of inflammatory hyperpigmentation. . Well your doctor has prescribed right medicine . Kojivt cream contain kojic acid cream which is very effective and safe for long term use and azelaic acid is also very good . I would suggest you to wash your face twice a day with cold water and exfoliate your skin with non comedogenic exfoliant to remove the dead skin . Also apply vitamin E oil before going to bedt at night . If condition doesn t get better in a month then again consult dermatologist . Doctor may recommend laser therapy or chemical eeling . Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
