Should I do microneedling again?

I was on Accutane last year and my derm recommended microneeding for my scars and pie. I got my first session 2 weeks ago (?) And ive noticed its gotten darker. Before I could only see the pie after I showered or if I was very warm because my cheeks would blush and the red spots were noticeable. Now its just brown spots even if my cheeks aren't flushed. I know one session wont do much should I go for the second session? (Maybe with prp this time) Also my face is a little more textured than before. (Before anyone asks no i was not in the sun I had it done on a friday and saturday and sunday I didnt go out at all just Monday when I drove to work which is a ten minute drive and I work indoors.)
