“Millions of people in the U.S. and around the world experience psoriasis and psoriatic arthritis, and there is no cure, yet.

Psoriasis can appear at any age, but often has two peaks of onset. The first is between 20 – 30 years of age and the second between 50 – 60 years of age. [11]

Psoriatic arthritis usually develops between the ages of 30 and 50, but can develop at any age.

The National Psoriasis Foundation defines mild psoriasis as affecting less than 3 percent of the body; 3 percent to 10 percent is considered moderate; more than 10 percent is considered severe. For most individuals, your hand is about the same as 1 percent of the skin surface.

However, the severity of psoriasis is also measured by how psoriasis affects a person’s quality of life. Nearly one-quarter of people with psoriasis have cases that are considered moderate to severe.”
