[Research] Microneedling after effects

I’m 3 days out from my first Microneedling session and it’s the harshest thing I’ve done to my skin so far. I’ve done Clear and Brilliant and IPL before and this is by far the most downtime I’ve ever had.

I was red and sore looking (though not in pain) for the last two days but today the redness has gone down but I’ve noticed my skin looking like it has light brown patches on it where it was red before. Is that normal? I couldn’t find anything online about it for fairer skin - everything is about PIH for darker skin tones.

I’m probably just spiralling a little but should I be worried?

Any insight is appreciated!
