Mechanisms That Trigger Psoriasis
Usually, a victim of psoriasis first notices a small sore somewhere on the body, a sore that doesn’t heal. It just seems to get worse and begins to spread. More sores then erupt in different areas. Some of the sores remain small or eventually disappear, but in most instances, they get worse as time goes on, and the patient begins to seek relief. There are occasions when the first signs of the disease appear after an injury or an abrasion of the skin. The damaged area does not heal properly and psoriatic lesions begin to develop along the site of the injury. This is known as the Koebner phenomenon. Vigorous scrubbing, scratching, or picking at the area only makes it worse. Low humidity, systemically administered drugs, and severe emotional stress can also be triggering factors preceding the first outbreak of the disease. Even using a loofah sponge instead of a soft cloth or just your hands while showering can irritate the skin to the point of severe inflammation. There are many cases in which a pregnant woman with psoriasis seemingly improves during the gestation period. However, the disease usually returns after she delivers. The fact is that the body is prone to being psoriatic long before the first signs of the disease appear, because internal pollution, the major causative factor of the disease, first affects the body on the inside.

"Even a slight or mild sunburn can cause irritation of the skin and trigger a psoriasis flare", notes Beto, now the executive president of research for the National Multiple Sclerosis Society. This is called the Koebner response, which is caused by injury to the skin.
