What Is Psoriasis?
Psoriasis is a noncontagious common skin condition that causes rapid skin cell reproduction. This results in red, dry patches of thickened skin usually on the elbows, knees, and scalp. The chronic condition is characterized by raised plaque areas on the skin which may vary from minor localized patches to complete body coverage. It is generally considered a genetic disease thought to be triggered or influenced by environmental factors, such as lifestyle and stress. Psoriasis has been associated with increased risk of cancer, cardiovascular disease and immune disorders.
