About rf microneedling. How many days after the treatment collagen starts building and scars starts to lift up?

i had rfneedling treatment (25' non insulated) 4 days back , for 2 days my scars looked lift up and i felt good on 4 day scars went to where they were before for now no improvement .. my doc says on the 4th week collagen starts buildiing so is there any chance the my scars will show improvement after a month ie; they will lift up cause my scars became depressed again in just 2 days so m afraid it will remain like this ..
