What causes and triggers pustular psoriasis?

ANSWER

Psoriasis is an autoimmune disease. Your immune system usually sends white blood cells to fight off disease in your body. But in this case, they attack your own skin by mistake. A few things can trigger psoriasis flares:

A mutation, or change, in a specific gene may make you more likely to get pustular psoriasis. If you have this gene, one of those triggers could set off a flare.

  • Medications, such as steroids
  • Something that irritates your skin, like a topical cream or harsh skincare product
  • Too much sunlight
  • Stress
  • Pregnancy
