I want to figure out the right direction regarding whether getting acne treatment is the right thing to do.

I try to take good care of my skin, but for the past few years, this cycle has repeated itself: just when I think my acne has subsided, it flares up again. I've tried washing my face thoroughly and cutting down on irritating foods, but nothing has improved, so I've come to the conclusion that I need to address the root cause with an acne treatment.

I’ve heard that there are lasers used in acne treatments that work directly on the sebaceous glands to help reduce recurrence. I would like to ask if I can expect these treatments to be effective even in cases of recurring acne like mine. I am also curious whether it is possible to receive treatment while inflammatory acne is active, or if I should wait until it has subsided somewhat.
