Are Scars Fungal in Nature?

From a Iodine product review on Amazon

Heard from a friend that iodine is good for reducing/eliminating scars. I have a bad scar from a burn a year ago on my arm. About 3 1/2 weeks after applying some on the scar with a Q-tip it is gone! My scar was about the size of a dime. It’s amazing. I was kinda worried about it but the iodine took great care of it.
