About 4.5 million adults in the United States have psoriasis,1 a chronic, often uncomfortable and disfiguring disease
typically lasting more than 30 years. Approximately half a million individuals
find the disease a substantial problem in everyday life. Fewer than half of
those affected by psoriasis find their treatment highly satisfactory.1
