Although psoriasis is a common condition, it is not as well understood as it should be. Thought to be a disorder of the immune system, the symptoms of psoriasis are caused by an overgrowth of skin cells. The condition presents as thick, scaly patches that can be red or even silvery. The most common form of psoriasis, called plaque psoriasis, most commonly appears on the scalp, elbows, and knees. Treating psoriasis doesn’t need to be complex. The medical professionals at Foothills Dermatology use a blend of the latest, most promising therapies to create results that endure.
