There seems to be multiple issues and all of them need to have a common reason. Finding a cause is mandatory to treat it effectively. ​​Acne treatment has multiple stages - to control new breakouts, to clear the sequalae (pigmentation and scars) and to prevent a relapse. If you have active acne lesions, it should be controlled on priority basis. ​It also depends on the age of t​​he patient and if planning for marriage or not. Various issues need to be decided before initiating the treatment. The dosage and duration is decided​​ by your dermatologist. You need to be patient with the treatment protocol as it takes months to see initial improvement.
