What is Psoriasis?
Psoriasis is a chronic and reoccurring skin disease that produces red, scaly, well defined patches affecting any part of the skin on your body.
It is only an acceleration of the usual replacement processes of the skin. Normally a skin cell matures in 21 to 28 days during its passage to the surface where a constant invisible shedding of dead cells, as scales, takes place. Psoriatic cells, however, are believed to turn over in two to three days and in such profusion that even live cells reach the surface and accumulate with the dead cells in visible layers. Psoriasis affects both sexes equally. It may appear for the first time at any age, although it is more likely to appear between the ages of 11 and 45.
Types Of Psoriasis

Causes Of Psoriasis
Psoriasis may be one of the oldest recorded skin conditions.It appears, however, that a genetic tendency needs to be triggered off by such things as injury, throat infection,sunburns, certain drugs and physical and emotional stress. Recent research has identified genes that may lead some people to be more susceptible to psoriasis, but some people who are genetically predisposed may never develop the condition.
Treatment of Psoriasis
- Keeping the skin soft and moist is helpful. Apply heavy moisturizers after bathing.
- Do not use cosmetics or soaps.
- Avoid itching that can cause bleeding or excessive irritation.
- Anthralin is an effective treatment for many cases of psoriasis.
- Use a humidifier in the home.
- Protect against skin injuries and skin infections.
- Bathing in hot water may help reduce scaling.
Topical treatment : The main topical treatments are corticosteroids, vitamin D-3 derivatives, coal tar, anthralin, or retinoids. There isn’t one topical drug that is best for all people with psoriasis. Because each drug has specific adverse effects, it is common to rotate them. Sometimes drugs are combined with other drugs to make a preparation that is more helpful than an individual topical medication.
Phototherapy : The ultraviolet (UV) light from the sun slows the production of skin cells and reduces inflammation. Sunlight helps reduce psoriasis symptoms in some people. If psoriasis is widespread, as defined by more patches than can easily be counted, then artificial light therapy may be used.
