Excema or psoriasis , this has been the question all my life, I have been diagnosed as having one or the other by various doctors since before I can remember. I had other symptoms of it being psoriasis, such as ridging and bubbling in my fingernails, joint pain and swelling, abdominal bloating and digestive problems, and dry eye problems, all of which are considered symptoms of psoriasis, but in my research can also be symptoms of other problems as well, all of which, for me, doesn't matter anymore because I get none of the symptoms since starting to heal myself naturally using good organic produce and supplements.
Eczema will be red and flatter. Psoriasis is thicker and patchy. There are a lot of extra cells produced from the unbalanced cGMP. The extra cells cells flake off and generally have a more silvery appearance.
