Psoriasis

Psoriasis is a chronic, immune-mediated disease that results from the overproduction of skin cells, resulting in their accumulation on the surface of the skin, which causes red, scaly plaques that may itch and bleed. It is estimated that approximately 7.5 million Americans and nearly 3 percent of the world's population are living with psoriasis and nearly one-quarter of those people have cases that are considered moderate to severe.

What is Psoriasis?

Psoriasis represents a chronic inflammatory skin condition with a complex pathophysiology and significant genetic background.
