The real question is not how they flattened it. It is whether the skin will keep building the same scar. A keloid is excess collagen that doesn't know when to stop so cryotherapy can shrink it in minutes and still leave the same genetic tendency in place. Facial keloid come back often because the area is under constant movement and tension. That is why a freeze in the bathroom looks only the first round.
Most women leave the hospital never having seen what childbirth actually does to the pelvic floor. Ligaments stretch, organs drop, and a problem that is mechanical gets treated like a secret. A pessary is not a last resort. It is often the simplest way to restore support without surgery, and animations like this should be in every prenatal class instead of something people find at midnight on X.
