Psoriasis 101


Psoriasis is an immune disorder that causes raised, red, scaly patches on the skin.

Psoriasis is not contagious. It is not something you can "catch" or that others can catch from you.

The rash of psoriasis can appear anywhere on the body, but it usually appears on the outside of the elbows, knees or scalp.

Some people report that psoriasis sometimes itches, burns and stings.

The rash of psoriasis is caused by the skin cells growing abnormally fast. This leads to the skin accumulating in thick lesions.

The cause of this rapid skin growth is not known, but the immune system and genetics are important factors. Usually, something triggers psoriasis to flare.

Most people with psoriasis experience their first flare sometime between 15 and 35 years old, but it can develop at any age. About 10-15% of those with psoriasis get it before age 10.
