Who's At Risk
Psoriasis is common; approximately 1 or 2 in 100 people in the US are affected. It can be seen in anyone of any age but is very rare in infants and more common in teens and adults. Psoriasis is also more common in whites than African Americans. Psoriasis affects men and women fairly equally, with women tending to start showing signs at a younger age than men.
