Pregnancy has done wonders for my skin acne prone skin. Any tips to help heal the redness/scars that remain?

I am 36 and have struggled with acne my whole life. I have a few small acne scars and redness that have remained from breakouts. My skin has cleared up so well during pregnancy now I feel I can finally tackle the redness/discoloration. I’m sure it will go haywire again once baby comes due to hormones but hoping to find a few all natural products that might help the redness fade while there’s still no breakouts. So far, I’ve tried rosehip oil but that made me start to breakout so I stopped. Any recommendations?
