I thought surface use of Iodine (for cystic acne, etc.) stayed purely on the surface. But I'd read elsewhere on the forum that it gets absorbed into the bloodstream like taking drops/tablets orally.

Is there any rough ratio of what it might be? Cystic Acne was one of my lovely side effects from Lithium, and I've started to use Iodine on my shoulders to get rid of them. It's smoothed them out (or in some cases, brought them to the surface) but I've also had stronger detox side effects over the past few days. I've literally just put it together right now, so I wanted to see how I can best balance this for my body.
