RF Microneedling. How many days after the treatment collagen starts building and scars starts to lift up? (Photos)

I had 2 sessions of RF Micro needling treatment with a 40 days Gap in between for 2 days after each treatment my scars looked lift up and i felt good and after that my scars went to where they were before And also i see a significant amount difference in scars during mornings and the same old depressed scars in the evenings or after i am tired. So is there any chance that my scars will show any improvement and if so how many treatments should i undergo and expect good results in how many Mths?
