Okay, have just tried the iodine thing, 3 times a day for the first two days like you suggested but by the 3rd day my skin was so sore and burning that my family begged me not to do anymore and thank goodness I didn't. After 4 days of watching my skin go very hard and crusty - to the extent that I couldn't open my mouth wide enough to eat! My skin began to crack and flake. It's now almost completely flaked off (in thick scabs I might add) and underneath is the most red raw scarred looking skin. It looks far worse than the rash ever did.
I wish I had never tried this method. I think I may have permanently scarred my face. I want to cry. I 'm hoping with time the redness and the lacerated look of my skin will fade.
DO NOT PUT IODONE ON YOUR FACE!!! IT WILL SCAR YOU.
