Is it possible for acne to reappear if the precautions are not followed after a treatment?

I've heard a lot about how important aftercare is after acne treatment, so I'm worried about it.

I'm wondering if my acne could get worse again if I don't properly follow the precautions after the procedure.

I would like to know when I can resume things like drinking or exercising after getting an acne treatment, and I am also curious about how long I should avoid behaviors that irritate the skin.

I'm worried that the effects might wear off if I just go about my daily life without thinking. I would appreciate it if you could share your experiences on whether there is a big difference between when I manage it well and when I don't!!
