How long will professional laser last vs at home IPL?

I’m just about done with an initial 12 week IPL male Brazilian course at home. Results seem good, but I know they are highly temporary.

I am considering follow-ing up with a few in-office laser sessions, and then potentially doing electrolysis for the few grays that likely will remain (electrolysis is not my thing so looking to do as little as possible but open to zapping a few grays if needed)

I know even in-office laser is temporary, but will it at least last longer than the IPL course? Or am I basically wasting my time with that?
