Hence, read the complete article to know the Psoriasis causes.

What Causes Psoriasis?

We know that our body produces new skin cells in the deepest layer of the skin. These gradually move up through the layers of the skin. When they reach the outermost level, they will die and peel off. It takes around takes around three to four weeks to undergo this process for normal people. But for the people with psoriasis, it takes about 3 to 7 days only. The skin cells may multiply upto 10 times faster than a normal person. Hence, the cells that are not fully developed build up rapidly on the surface of the skin and causes patches on the skin. Psoriasis appears as red or pink small scaly bumps that merge into plaques of raised skin. The exact cause of psoriasis is not entirely known. But scientists believe that psoriasis is the result of several factors, including genetics, environmental factors, and the immune system.

It causes our skin cells to multiply quickly and to accumulate on the surface of the skin. These excess skin cells will create thick, scaly patches called plaques. Plaques most often develop on the Elbows, Knees, Scalp, Palms of the Hand, Lower back, and soles of the feet. More specifically, one key cell is a type of white blood cell called a T lymphocyte or T cell. Usually, T cells travel throughout the body to detect and fight off foreign substances, such as viruses or bacteria. If you have psoriasis, however, the T cells attack healthy skin cells by mistake, as if to heal a wound or to fight an infection.
