From what I recall watching Daniel's vids, he noted that if he did not get adequate amounts of sun after a couple of days he would get slight buildup. This led me to believe that his exposure to the sun was helping create vitamin D and therefore regulating cell turnover. This would make sense because Psoriasis and eczema sufferers have similar experiences. And even Daniel himself said that on a trip to the Grand Canyon, I believe, his friend's Psoriasis cleared up while being exposed to the sun all day. I personally believe for most of us, EC is related to or shares common traits of psoriasis, eczema and other skin related conditions.
