What can cause psoriasis?

ANSWER

Psoriasis is an autoimmune disorder that can run in families. Your skin cells grow too quickly and pile up into bumps and thick scaly patches called plaques.

You’re more likely to get psoriasis if your blood relatives also have it. That’s because certain genes play a role in who gets the condition.

But you can get psoriasis even if you don’t have any of the genes linked to it. Scientists believe things in the environment may be another key contributor to psoriasis.
