ELI5: What happens when external scar tissue is wounded a second time? How many times could the same area theoretically re-heal, and what would be the consequences apart from appearance?

It'll just keep scarring in different ways. It'll continue to re-heal unless you contract some kind of illness that prevents your body from healing. There's no real consequence, either. Your body will just keep working until something stops it from working.
