There are different ways to achieve a flawless skin after acne and it needs medical interventions. 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. Remember combining treatment modalities help to achieve desired results earlier. Your dermatologist will decide a treatment plan for you after a consultation. Apart from active pharmaceutical medicines, a healthy diet and lifestyle is mandatory to achieve results.
