Know the causes

What causes psoriasis?

The exact cause of psoriasis is unknown but is most likely caused by an autoimmune response. More specifically, one key cell is a type of white blood cell called a T lymphocyte or T cell. Normally, T cells travel throughout the body to detect and fight off foreign substances, such as viruses or bacteria. If you have psoriasis, however, the T cells attack healthy skin cells by mistake, as if to heal a wound or to fight an infection. Psoriasis is not infectious or cancerous.

Steroids and other anti-inflammatory drugs applied to skin (topical) are for mild to moderate cases and as combination therapy for more severe cases.

Other treatments include salicylic acid in mineral oil (removes plaques), PUVA (psoralen and exposure to ultraviolet light A[UVA]), immunosuppressant drugs (e.g. methotrexate, isotretinoin), antihistamines (for itching) and antibiotics (for secondary bacterial infections).
