I have had this for 7 yrs.  It is a combination of dry skin and stress induced psoriasis.  I found that taking garlic tablets (builds immune system) and B complex vitamins (stress fighter) makes them DISAPPEAR in one day!!  Also a good non allergic moisturizer on patches helps. If I stop the garlic and B vitamins, even "one" day,..it comes right back...Goes to show you: we are what we eat and we have the natural remdies to cure anything right here at our disposal on earth.  Try these home remedies, otherwise the patches literally set up housekeeping forever!!!  Hope this helps.....
