I have had good results with iodine painted on moles. From one huge black mole to a barely noticeable light brown mark now. I painted on the iodine at night, after a few weeks I was away on holiday and when I came back was not as regular with the routine but the mole was fading. I stopped for a while and the mole just kept on fading. I will start again now and see if the last bit disappears.
