Psoriasis is a complicated disease that is not well understood even though it’s been described in medical books for more than 100 years and has affected celebrities such as Kim Kardashian and LeAnn Rimes.

But your dermatologist must determine which types you have, since medications vary depending on the kind of psoriasis.
