Is applying plenty of soothing gel as home care essential after laser treatment? lol

I'm finally making up my mind to go to the dermatologist in a few days to get a pretty intense laser treatment to tighten my pores and erase my scars. I'm already scared because I heard that right after the procedure, your face gets irritated and burns like a burning sweet potato, getting super red. I saw in other people's tips that they really emphasize post-treatment care, like applying a generous amount of cooling and soothing gel like a mask when you get home, just like in the picture! Is it true that I need to do intensive home care after the laser treatment—frequently reapplying moisturizer and regenerating ointment—to get rid of the redness quickly and plump up my skin? I heard that post-treatment regeneration care is just as important as the procedure itself. Besides applying a lot of soothing gel, if anyone knows any other great tips for laser aftercare, please share them with me!
