Psoriasis is an autoimmune disease of the skin that predominantly involves scaling and inflammation. Aside from its physical manifestations, psoriasis can also result in debilitating psychological effects for those suffering with it. While conventional medicine typically treats psoriasis from the outside in, the reality is that it is an issue that comes from within, and should be treated from the inside out. Things like your genetics, diet, and environmental influences can all contribute to psoriasis.
