Neutrophils of white blood cells get divided. These reach the upper layers of skin to guard the body against the invasion of foreign bodies. They result in the formation of pus, and excessive production of the skin cells. These skin cells accumulate to form pustules, sores, raised bumps, lesions with pus, scales, dryness of the skin and redness along with inflammation. They carry on the process of inflammation as a line of defence in response to the immune attack triggered. This is the condition called psoriasis.
