I have had psoriasis for over 30 years now. The only consistent thing that makes it go into regression is getting a lot of sun in the late spring / summer. Unfortunately I live in a northern state, so over half of the year I do not get UVB from the sun and my psoriasis starts coming back in the mid-late fall. I have tried Vitamin D supplements but they don't seem to work for me. Even at high dosages.
