How to extend the duration of acne treatment?

Hello. I struggled a lot with acne treatment from around May to October of last year. It was very expensive and emotionally draining back then, but I somehow managed to finish the treatment. However, breakouts have started coming back lately, and I am extremely worried. I tried to extend the duration of the effects by getting sebum-suppressing laser treatments regularly, once or twice a month, but it still doesn't seem to be enough. I am debating whether to start treatment again, but is it normal for the effects to be this short-lived? Is there any acne treatment that can extend the duration? I just want to live without worrying about my skin.
