Retin a micro 0.08% gel (1 week) and microneedling and prp.

I just started using retin-a micro 0.08% 1 week ago (3x a week), my skin looks lil smoother , ice pik scars look smaller, but i haven't reached the purging phase yet, there is very lil flaking but no irritation , no redness at all... i've microneedling scheduled in 4 days from now. I was wondering if i should stop using retin A micro or postponed microneedling for after purging stage? If purging does happen, i'm afraid it would leave more scars and microneedling won't be any good?
