I've painted Iodine on various parts of the body, and it fades at various rates. Some it might take 1-3 hours (like on arms or legs), others up to 24 hours (like fatty areas). Today, I spilled some from the bottle and decided not to waste the spill, so just wiped it up with the palms of my hands. It's almost gone now after 5 minutes, many of those minutes without the palms exposed much to the air. Has anyone noticed the palms absorbing quicker? I wouldn't have thought I was that Iodine deprived, since I'm taking 1/4 tsp. twice a day, and have been sporadically doing it for over a year now, but maybe my body is that desperate for it.
