During this time other cells are produced in the skin depth, and they gradually rise to the surface within 30 days, arriving just in time to replace cells that are ready to fall.

Our immune system reacts to a stimulus in case of psoriasis. These stimuli may include prolonged stress or infection or severe disease. Our body begins to push young cells to the surface faster than It should have normally. In fact, they come to the surface in a few days instead of a month what would have normally. Because the new cells arrive so quickly, the cells already existing on the surface do not have time to die and fall by themselves. So, produces a mixture of these cells, characterized by dry skin and the appearances of red spots disorder known as psoriasis.
