How often should I micro-needle at home for best results? Is it normal for skin to look worse the day after and then tighten up?

I've had success with home micro-needling using .5 mm under and above my eyes (up near brow, not on lid) and 1.0 mm on chest and neck and follow with non-acidic serums. I use the .5 every other day and the 1.0 about every 4th day. Off days, I use Renova. I am thrilled with the results which include skin tightening and softening of lines. Am I allowing sufficient time between rolling? Oddly, my skin is pretty saggy and puffy the next day but great by the second day. This happens each time.
