Psoriasis causes the skin cells to grow too quickly. Ordinarily, skin cells grow and flake off in four-week cycles. When someone has psoriasis, this process can occur in days instead of weeks. This causes thick patches, called plaques to form.
According to the National Psoriasis Foundation, there are five different forms of psoriasis, which include:
Plaque psoriasis: Presents as red patches.
Guttate: This type of psoriasis looks like small red spots on the skin.
Inverse: Presents as red lesions within the folds of the body.
Pustular: Contains pustules surrounded by red skin.
Erythrodermic: Shows itself as exfoliation and hot redness.
There are several triggers that may intensify the symptoms of psoriasis. Common triggers include, stress, certain medicines, and the hot Arizona sun (among other possible weather conditions).
Available treatments for psoriasis range from creams and ointments, to prescription medicines and other medical treatments. The purpose of psoriasis treatment is to reduce inflammation by slowing the rapid growth of skin cells. Steroid based creams are one example of a treatment used to relieve itching and reduce inflammation. This occurs by blocking the production of more cells.
