5 months po, is it normal to still have big red raised scars around areolas? Like my nipples have "slid off" somewhat? (Photo)

Your scars are excessive and it sounds like you are doing many of the usual things to improve them.  Your plastic surgeon should be able to offer you some additional treatments, such as intra-lesional steroids, which can speed your scar maturation.

I know it isn't fun, but
scars take a long time to mature and finalize. I would tell you to give
it a year before making any decisions on revisions etc. In the meantime,
there are some scar products and strategies like using paper tape to improve
things (sounds like you've tried them all). I typically like to do those in the first three months instead of
after though. Father Time is your friend. Try not to focus on how
they look now- instead, focus on how much better your contour is. I wish
there was a magic cure or something more to tell you.
