Hang in there you will heal yourself. At some point you will be looking back at this part of your life with new eyes. Your just in the midst of it right now that is why it seems a bit dark.
Are you doing vit c daily? Have you tried MSM? Are you having enough BM's per day? Sometimes silica helps w/ skin stuff (like Biosil or ionic silica. Also sometimes putting a couple of teaspoons of apple cider vinegar in water and drinking 3 times per day cleans the blood and helps with acne. Some people on this forum have found that zinc helped them. Infrared saunas (this personally helped me w/ acne)
Also when I first tried Iodine in the form of lugol's, kelp and plain potassium Iodide pills I broke out even worse and I had to stop. I had to take a different route an easier one . So I took Iosol which gave me some detox symptoms ut very managable, then found magnascent- I used these two for several months and did at one point 50 drops of iosol and magnascent and had months of managable detox. Then I recently (a couple of weeks ago) revisited potassium iodide(KI) and I now can handle it w/ out the throat closing and major acne- this is huge for me I thought I would never be able to handle KI.
I see you have done a lot of cleansing. I have as well. All of the cleansing especially after to many liver cleanses I really broke out. I later realized I was a depleated person depleating my limited reserves even more and putting major stress on my adrenals. It was to much I lost to many minerals. Your body requires
mineral/nutrients to neutralize toxins. Once again i wasn't able follow the majority. Listening to my body became king not a protocol or what others did. The protocols served as guidance but for what ever reason rarely worked with my body.
Sorry for so many questions and suggestions but like many things in the body acne can result for many different reasons (adrenal issues, gut stuff, emotional, allergies, lung...) But at least we know some things are certain. Like if your major elimination channels are blocked like the kidneys and colon the body will naturally eliminate through the skin so you don't reabsorb toxins. In chinese medicine the lungs open to the skin.
You also might need to take a break from Iodine perhaps the detox is heavy for you now.
I also experienced acne for the last nine years and finally my skin for the first time is starting to look healty and have minimal acne. I know it sucks but
once you get to the other side of misery its a gift.
