I have had dry skin spots for at least 15 years. Tried a lot of prescription creams and herbals. I got rid of most but there is one the size of a quarter on my leg that was bad. Recently I tried toothpaste on it; I think it is working since it is down to the size of a dime now and hardly visible. Anyone know about this? I like the Iodine reference; will get some - back to what our ancestors used - maybe it will help with spots on hand if toothpaste doesn't correct it.
