My experience: I CAREFULLY applied Lugols 2 x a day to my scar, every day. Eventually a scab formed over the area after about 2 weeks.
I continued applying Iodine 2 times a day and after about 1 month, the scab became itchy & fell off leaving PERFECT new skin.The only way you can tell there was something there is that the skin area where the kelloid used to be has not yet tanned.
There are many articles on the net using Lugols to get rid of warts, kelloids, scars.
Search Google, "Iodine Kelloids"
