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?

You are not going to see significant results with a 0.5 roller at home.  I recommend having a deeper microneedling session done with a doctor and then using that roller to help prolong your results.  At the doctor's office, you face is numbed and the needles can be over 2mm.  I have attached a video.  Hope it helps.Dr. N

We do a significant amount of microneedling in our practice and everyone looks more swollen and red the day or two after and then your skin improves.   We combine all our lasers with microneedling and PRP.  Best, Dr. Emer.

Home microneedling is safe and it does look worse for 24 hours before it gets amazingly better.Dr H Karamanoukian#RealSelf100 Member
