Tummy tuck?? Muscle repair?

Any twin mommy’s out there with twinskin? My 1st born was 10lbs and my twins were carried to 38w1d and one was 5.7 lbs and one was 6.14lbs pretty big for twins, anyway I’ve lost all the weight and then some the wrinkly loose skin is very bad and my muscles have at least a 3 finger width gap. They don’t even engage when I try to flex them. I am looking into surgery to repair the muscles and remove the extra skin. Anyone else considering this or have got it done? I’d love some advice from anyone who has gone thru it
