Acne treatment has multiple stages - to control new breakouts, to clear the sequalae (pigmentation and scars) and to prevent a relaps​e. ​ So if you have no new acne lesions, then acne scar treatment can be started. Now-a-days many chemical peels also offers realistic promise​ like salicylic acid which is done by a dermatologist. He may also consider lasers or dermabrasion based on type of scars. Drak circles need to be evaluated and targeted specifically. ​​Peels like glycolic acid and lactic acid  ​will help in lightening​. Dermapen in combination with mesotherapy also helps. ​ You may need oral medications. Consult a skin specialist
