I have had psoriasis for many many years and have tried so many treatments. I have found an over the counter ointment that has really helped me and I have stubborn psoriasis which does not always respond to other medications. Either they work for a while but come back within months or they do not work at all. I saw an ad for an over the counter product and decided that I had nothing to lose. The product is called MG217 and it worked for me. It is an ointment with a slight ordor but I am very satisified with the results and what to pass this information to anyone interested.
