At this juncture, I would NOT use topical iodine. Wait until the skin is repaired and not inflamed anymore.
At that time, after it's settled down, try topical (Povidone) Iodine before bed. See how that affects your skin. Get to that point, and then return and tell us your findings. We'll be happy to take it to the next level with you!
Are you taking Iodine internally (Lugols/Iodoral)?
