Will there be a difference after just one pore laser treatment?

I am looking into laser treatments because I am concerned about the pores around my nose and cheeks, and my biggest question is how many sessions are typically required. I understand that the pores won't disappear completely with just one treatment, but deciding on multiple sessions right from the start feels a bit overwhelming.

I would like to try it once first to see if it suits my skin and what the recovery period is like before proceeding with additional treatments.

With pore laser treatment, can I expect to see a slight improvement in skin texture even after the first session? Or am I wondering if I need to receive a certain number of sessions to judge any changes?

Can the required number of sessions differ for areas with high sebum production, like the nose, and for areas like the cheeks where pores are visible due to skin texture? I would like to be informed of a realistic estimated number of sessions and intervals during the consultation.
