What is psoriasis?

Psoriasis is a common chronic skin condition that is persistent and untreatable. It is cyclical, meaning there might be periods when the symptoms either lessen and even disappear completely or worsen. Different people may experience different degrees of severity.

Why is this happening?

Psoriasis greatly affects the development of skin cells. It brings about the rapid buildup of cells on the skin’s surface, leading to the formation of red patches that are not only dry and scaly, but also very itchy. This condition is normally worse in patients suffering from arthritis.

There is no known cure for psoriasis. However there are medications and therapies that can control it. [note]The type of treatment to be used depends on 3 factors:[/note]

  • The type of psoriasis
  • The areas affected
  • The severity of the infection

Normally, there are 3 approaches used in the treatment of psoriasis. They can all be combined. These include:

Topical treatment

This includes the application of medicines, specifically creams and ointments, to the affected skin area. Topical corticosteroid is the most common medication used. It aids in slowing down skin cells production, hence bringing about less itching and skin inflammation. Vitamin D analogue is another medication that works in the same way.


Phototherapy involves exposing the skin to different types of light. The light can either be natural such as sunlight and UVB, or artificial such as PUVA, which is psoralean combined with UVA. PUVA is normally used in severe cases. Exposure to sunlight helps in alleviating the symptoms.

Oral and injected medicines

If other treatments have not been successful, injections and oral medications can be prescribed in an effort to control cell production. Acitretin and Methotrexate are some of the prescribed medicines that have the ability to slow down the cell growth, hence suppressing the inflammation.
