   Is psoriasis an autoimmune disease?

   • Based on research developments in the past few years, psoriasis has generally been classified as an autoimmune disease. This means that your immune system cells, called T cells, mistakenly attack your own skin cells as foreign invaders. This causes your skin cells to rapidly multiply, leading to the characteristic psoriasis skin lesions.

   How long does psoriasis take to grow?

   • In people who are considered healthy, new skin cells normally travel from deep within the skin to the surface of the skin in about a month. The process is called cell turnover. If you have psoriasis, new skin cells rise to the surface within days. The rapid cell turnover leads to thick patches of skin. What Causes Psoriasis Autoimmune Disease?
