From what I can gather the article is about Iodine tincture which you would expect to evaporate quickly because of the alcohol, Colloidal Silver which they say evaporates more quickly for some reason and KI. I do not see Lugol's tested. They say, "Colloidal Iodine evaporates somewhat more quickly than tincture of iodine; Lugol’s solution is more stable than either of them." Is there a study that test's Lugol's on human skin?
