For about ten years I had recurring small skin lesions and sores that required many appointments with a dermatologist and two surgical removals of squamous cell growths, one on the side of my cheek and the other on my left ear. In about May of 2023, I began to take a couple of tablets of kelp each day because I knew that kelp is rich in iodine and that the skin needs iodine to be healthy. (For many years I had refrained from taking iodine in any form because I assumed I did not need it: I had an underactive thyroid and had been taking 88 mcg of levothyroxin with annual T3 and t4 tests for at least twenty years.) After about six weeks, the lesions and sores on my skin disappeared and my skin has remained healthy for the past year. I no longer see a dermatologist. Hope this helps someone.
