About Psoriasis

Psoriasis is a chronic auto-immune disorder, that shows itself as a disease of the skin, and sometimes the joints too (Psoriatic Arthritis). Skin cells normally take 3-4 weeks to replicate and to be replaced. However, in Psoriasis sufferers this process occurs within 3 to 6 days, resulting in red, painful, itchy, flakey lesions on the skin.

Psoriasis is known to have a genetic element to it, however there can be many forms of triggers, such as stress, infections, smoking, alcohol or other injury to skin.

There are many types of psoriasis including Guttate, Plaque, Inverse, Pustular, Erythrodermic, Nail and Scalp psoriasis.

In a nutshell, the cells are replaced quickly in psoriasis sufferers due to a problem in the immune system. The immune system is the body’s first line of defence against diseases, helping fight against infection. T-cells are one of the main types of cell used by the immune system. T-cells normally travel through the body to detect and fight things like infections, but in people with psoriasis they start to attack healthy skin cells by mistake. This causes the deepest layer of skin to produce new skin cells more rapidly than usual, which in turn triggers the immune system to produce more T-cells.
