LID? Pre RAI? (New to the lingo here, sorry)
When I was on a generic of Synthroid, I broke out in something much worse than acne....it was more like boils and went from all over my face in areas where I have never in my entire life broken out, but mainly around my mouth and chin all the way around the back of my neck and up into my hair. I stopped taking the Synthroid and started taking herbal thyroid boosters and not only did my skin immediately clear up but my hair started growing back and was WAY softer AND I dropped about 35 pounds with not a whole lot of effort.
Really? Acne is affected by synthroid? By generics, too? Mine isn't bad, but I'm constantly getting a new outbreak somewhere.
I find that the higher the levels of my Synthroid the worse my acne. In fact the best my skin has looked in YEARS was when I was on the LID (pre-RAI) and my TSH was 76+.
