Answer: There is no "cure" for psoriasis, just maintainance. One guy came into my work to get some more revlon tinted cream for his son, he said that worked good for him. But revlon no longer makes the cream stick he wanted, so he got the liquid, and I don't know how that worked out cause the guy never came back.A guy I work with uses vaseline with shea butter, but he still looks all flakey.
