Psoriasis is a persistent inflammatory skin disorder that affects up to 3% of the population. It typically presents with deep red bumps and patches with an overlying thick white or silvery scale.

Psoriasis is generally thought to be a genetic disease that is triggered by environmental factors such as trauma to the skin, infection, and certain medications. These lead to an autoimmune attack on the skin. Psoriasis can also affect the nail as well as joints (psoriatic arthritis) and has now even been linked to other diseases (comorbidities) such as: diabetes, heart disease, hypertension, and even cancer.

Because it tends to be a chronic lifelong disease with variable courses, it is important to be evaluated and managed by a board-certified dermatologist. While psoriasis cannot be cured, there has been remarkable progress in its treatment in recent years. There are now many treatments to help clear the disease and maintain control, and to restore quality of life.
