True story: my mom has plaque psoriasis and I was starting to develop symptoms as well (the condition seems to be heritable). I saw a dermatologist about it, and she prescribed a particular cream as well as doing 15 mins of UV therapy every day on the affected areas (knees and elbows were the worst). I wasn't the best at following medical advice at the time, but the cream helped some. About a year and a half ago, I started taking vitamin D after my doctor told me I was slightly deficient. Within two months, there was no indication of plaques on my knees or elbows, and the little nodules that would appear on my palmar surfaces on my hands and feet became much less frequent. I am convinced that supplementing vitamin D was much more effective than any cream, and definitely less obnoxious than holding my knees and elbows to the sun at an open window on a sunny day. When I get outside frequently, I notice that basically all of my symptoms go away. Long story short, take your vitamin D! Consult a doctor and don't take too much, since it's fat soluble and can build up to toxic levels in your system; also, since it is fat soluble, make sure your diet has enough good fats to help absorb it (guacamole and olive oil are two of my favorite supplementary foods with vitamin D).
