A remarkable piece of tissue when needed for rhinoplasty , but no, I have not read that it could regenerate. It's purpose is to contain the muscle but its removal has never presented an issue in my experience
It is normal to see a few whitehead or pimples on your nose when the tapes and splint come off - but not months later. No, you have not ruined your nose - but do go see your surgeon, show him and come up with a treatment plan.
