When available, we show information about how well a treatment works with 100 faces. If 100 people take a treatment, the number of green smiley faces shows how many had excellent improvement of their psoriasis. Excellent improvement means the severity of their psoriasis got better by 75% or more. With each group of faces you’ll see a statement of how many people saw improvement and how many weeks of treatment it took. In the example here, 73 of the 100 faces are green and 27 are black. 73 out of 100 people experienced excellent improvement.
