Dealing With A Psoriasis Rash

What causes a psoriasis rash is often unknown as is the exact cause of the skin disease itself. A psoriasis rash is often something that comes and goes, and may affect only small areas or may cover large parts of the body. Psoriasis is a very common skin disease, though fortunately most cases are mild, and some who have the disease may not even be aware of it.

Fortunately, a psoriasis rash is treatable, if not curable. Few diseases are curable as long as the cause remains unknown. One cause, though not yet perfectly understood, is believed to be genetic in nature. Psoriasis has in many instances be found to run in families, though if either or both parents have the disease, it does not necessarily mean their children will have it.

The Immune System And The Environment - The immune system is known to play a role, and although the role is also not completely understood, enough is known to make many forms of treatment possible, if not a cure. Under normal circumstances, our skin cells form, live for about 30 days and then slough off, to be replaced by new cells. The immune system produces what are called T-cells which have a nurturing influence on the growth of new skin cells. For reasons still unknown, the immune system may suddenly start producing abnormally large amounts of T-cells, resulting in an abnormally large number of new skin cell forming, which begin piling up on one another, dying off, and as a result causing inflammation which we experience in the form of a psoriasis rash.

Since the immune system plays a role with respect to a psoriasis rash, it's not unusual that the environment can as well. Allergens in the environment can cause the immune system to spring into action, again producing an overabundance of T-cells to protect the skin, and again resulting in an excess of new skin cells, leading to the rash.

Treatment - There are fortunately a number of ways to treat a psoriasis rash effectively, including topical medications, oral medications, ultraviolet light, and one or two home remedies. Most any skin moisturizer will be helpful, sometime in preventing flare ups, at other times relieving itching or discomfort. Corticosteroids and preparations containing vitamin D or salicylic acid are generally effective. Oral medications containing cyclosporine, acitretin, methotraxate, and soriatane are often prescribed. A few of the more common oral medications have potential side effects and may not be appropriate for everyone.

Photo therapy - Ultraviolet light, whether artificial or plain old sunlight is usually very effective in treating a psoriasis rash, and combined with oral or topical medications can often clear up the condition for months at a time. Not unexpectedly, psoriasis flare ups tend to occur more often during the winter months when sunlight is sometimes at a premium. When artificial UV light is used, a certain wavelength may be chosen as being more effective towards dealing with the particular situation. In addition there are UV wavelength which, while benefiting the patient, do not result in sunburn. UV treatments of this type are generally short enough in duration so any possibility of developing skin cancer, which can be caused by UV radiation, is not considered a risk. UV treatment falls under the general category known as photo therapy, and works primarily by killing certain cells known to be the cause of various skin diseases.

A psoriasis rash is a fairly common condition, it is not considered to be a particularly dangerous one, but as it does have cosmetic overtones can cause some people embarrassment and even psychological problems. The lack of a cure is at least somewhat balanced by the wide range of effective treatment available.
