Psoriasis is NOT a skin condition. It's a calcium issue caused by the buildup of excessive calcium proteins in the wrong places and linked to improper gut bacteria(like pretty much every other autoimmune disease). The reason they build up is because most people take in 6-8 times too much calcium in their diet since everything is fortified with it, but nowhere near enough Magnesium, Vitamin D3 and Vitamin K2 to deal with the calcium. So it goes to places it's not supposed to be...like the soft tissues(lupus, psoriasis, etc), arteries(atherosclerosis), hair follicles(balding), etc. It is manifested through the skin but attempting to cure it by treating the skin is akin to trying clean up dog sh!t off the floor by shoving it under a rug.
