How should I do home care after a dermatological procedure to make the effects last longer?

I remember my skin condition improving quite a bit after getting a simple treatment at a dermatology clinic a while ago, so I'm considering getting it again these days. I definitely remember my skin texture being more even and my makeup applying better compared to when I was just doing home care on my own.

The problem is that my skin felt good right after the procedure, but as time passed, it felt like it was returning to its original state. So, while the procedure itself is important, I think how you care for it afterward is even more crucial.

I usually just use basic cleansing, a hydrating ampoule, and a cream, but I'm not sure if I absolutely need to use a regenerating cream after the procedure, or when I can start exfoliating or using face masks again. I'm worried that if I take care of it incorrectly, the effects might wear off quickly.

How do you members do your home care after the procedure? Please let me know if you have a personal routine to maintain the effects for a long time or any products you make sure to use. Since I spent the money on this, I want to keep the results looking good for a while haha.
