As some of you may know, I believe that iodides can be a culprit in exacerbating acne.  What I didn't know is that it is probably more of a "bromide detox" from iodides than iodides causing acne.  I found a comment on a blog that I found fascinating that I'll post here:

"The elements bromide, chlorine and floride are all part of a group called “halides” and iodine is one of them, too. Our body loves iodine and every cell needs it. But bromide and the other halides that are similar in structure to iodine can get into the cell receptor sites that are supposed to be for iodine and sort of clog them up and the body starts having problems.

When you take a large dose of iodine the extra iodine goes around the body and starts kicking out the bromide that has gotten into the receptor sites and you get a detox reaction. Guess what one of the detox symptoms is? The “acne” that you are talking about!!! That is just the body throwing off the excess bromide and other crap. I got this symptom along with others like achy, mild headache, stinky underarms!

The various symptoms including the acne went away after a few weeks (I got the pimples sort of on my neck or my scalp or back or random places, including a few on my face.) The way to reduce the symptoms is to take a special sea salt and mix it in water and drink it and the chloride in the sea salt binds with the bromide and then it leaves the body when you pee. People think the iodine is “causing acne” but it really was the body just getting rid of bromide and other things it does not need."
