Oh, I think the iodine. It's wonderful what iodine can do for skin. Aside from the bromide pimples, of course :) Even more specifically, some people will paint Lugol's on skin "things" they want to go away. It can take awhile, but the demise is exactly as you described. Another view of it could be that the detox you've already been through has lightened the load for your liver, which then has capacity to do some cleanup of its own. Still due to what got started with iodine. Congratulations!
