Labia minora tear from childbirth - Can I reverse it? (photo)

I had two children several years ago and I didn't realize why my vagina was in pain at times during intercourse as I was told never to look down there after childbirth and it'll take time to heal. Well fast forward three years after my last kid, I decide to get shave down there for my first time and I can see my labia minora (the right side) is torn all the way in half. That's why it never felt right and my gynecologist told me it looks like the doctor screwed up during labor and snipped it by accident. He said it's more of a pain to fix even with labiaplasty (As it could cause more damage) and only recommended estrogen cream to help with the pain during sex. Is there any way I can reverse this childbirth damage? Is it utterly too late? :(
