Overview : What is Psoriasis?

Psoriasis is a common autoimmune disease with no cure. It is a condition in which the skin cells build up and start to form scales and itchy dry patches which leave the skin inflamed. There are visible signs of inflammation in the body such as raised plaques and scales on the skin. People suffering from psoriasis tend to go through cycles, experience flaring for a few weeks, and then it subsides for a while. The flaring up of skin is because of the overactive immune system that speeds up the growth of skin cells. On one hand, where the normal skin cells completely grow and shed off in a month, with psoriasis, on the other hand, the skin cells do this in a span of 3-4 days, and so instead of shedding, the skin cells start to pile up on the surface of the skin.
