I have just been given a home use LED mask for my birthday. Instructions are strange.
The instructions say that anyone with thyroid disease or taking thyroid medicine should not use it. Can this be right? I take 100mcg thyroxine per day as I had my thyroid removed 13 years ago. How would i be at risk if I use it? I thought LED light was safe. Would appreciate any medical advice re this issue. Many thanks in advance, Alison
