Psoriasis is a chronic skin condition which is a cause of an overactive immune system. This results in the rapid build-up of skin cells. Once the cells start building, they cause scaling on the skin’s surface.

Usually, skin cells grow in the deeper layers of the skin and eventually rise to the surface. Later on, they fall off and the process continues. Typically, the life cycle of a skin cell is one month. However, in people suffering from psoriasis since the production of cells is extreme, they do not have the time to fall off. As a result of which the cells start building up.

Psoriatic scales develop as thick, red patches and appear to be whitish-silver in texture. The condition causes inflammation and redness around these scales. Sometimes, these patches will crack and bleed.
