Raised Area on Face after Microneedling.

I had microneedling done for 2nd time exactly 3 weeks ago. The doc went a to 2mm and went quite hard either side of my nose along my smile lines. For 1 week I had what can only be described as red dry flaky skin/scabs in this area, which fell off. My worry is that the area where the largest scab/patch of dry skin was now is a little raised compared to the surrounding area. It has been 3 weeks Should I be concerned or is this particular area of the face is quite sensitive and still healing?
