thanks for sharing this aquarian. i have a slight thyroid issue. i have a hyper active thyroid. at the current moment, it is mild, and the doctor does not want to treat it with any medications, as she feels that the medication can fix one problem and make another problem appear, and since its mild, to make sure with another blood test in 3 months, that it hasn't progressed, but my concern is that even though its a mild issue, that this is the cause of my melasma. ah gosh so much to worry about!
