Psoriasis is a recurring autoimmune disorder characterized by red, flaky patches on the skin.

Even though it affects your skin, psoriasis actually begins deep inside your body in your immune system.

It comes from your T cells, a type of white blood cell. T cells are designed to protect the body from infection and disease. When these cells mistakenly become active and set off other immune responses, it can lead to psoriasis symptoms.

Even though there’s no cure, many treatments exist to ease the symptoms of psoriasis.
