Psoriasis Overview

Psoriasis is a chronic, non-contagious skin condition that affects about two percent of the population. While the cause is unknown, psoriasis is linked in some way to the immune system. Skin cells reproduce markedly fast with buildups resulting in scaly red patches. These can be seen typically in the knees, elbows, groin and scalp.

Mild cases of psoriasis start with dry, small patches on the skin. In more severe cases, reddened thick scaly patches may cover the whole body.

Although psoriasis is a non-curable condition, sufferers may experience long remission periods, especially in warmer climates where they have more exposure to sunlight.

There are four main types of psoriasis that a patient can be diagnosed with.
