Psoriasis affects various parts of the body from the scalp to the tiny toe, foldings of the skin to the folds in the groin. No area is unleft by its miserable sores and irritation. It can be confined to smaller patches in specific areas or can spread like a red patch all over the body.

But the immune system sends down unusual immune responses. By which the T cells get overactive and divide into more T cells and produce more white blood cells called neutrophils.

These cells surface on the skin, as it is the first line of defense for the body. They form pus, inflammation, excessive cell production, redness, and eventually into pustules and lesions. The blood vessels that are circulating through this area become warm and show up redness.
