Psoriasis is a chronic, noncontagious skin disease resulting from an atypical autoimmune response which leads to accelerated skin growth and the formation of skin lesions. Psoriasis causes skin cells that typically take a month to grow to form in a matter of days. This in turn leads to the buildup of cells on the surface of the skin which then form silvery scales over red, dry, itchy patches called plaques. The most common form of psoriasis (and the focus of this article) is the abovementioned plaque psoriasis, also referred to as psoriasis vulgaris, accounting for 80-90% of psoriatic patients.
