Is there a procedure to clear up acne marks on the back?

As summer approaches, I want to wear backless clothes, but I can't because of the acne scars remaining on my back. The patchy hyperpigmentation left behind where my severe acne used to be is unsightly. I've tried using body scrubs and whitening products at home, but they haven't improved easily, so I am looking into dermatological treatments. Can back acne scars be treated with a laser? I am curious if the procedure interferes with daily life, and how many sessions are typically required to clear up. I would appreciate advice from those with experience.
