Just thought I'd drop a message on here. I suffered with psoriasis and excema for around the last 15 years of my life. I would apply the creams daily. It started just on my elbows and behind my knees but it eventually progressed to pustular psoriasis on my feet.
I have a lot of ceoliac disease in my family, so i had been trying for a long time to cut out gluten to combat my psoriasis. I had been to see a private doctor who said I would have the disease for life and would never get rid of it.
It seems that cutting out dairy has healed my psoriasis almost fully. Its only been a week or 2 of massively cutting down my dairy intake, and my psoriasis is essentially healed. If you've tried lots of other things but not giving up dairy, definitely give it a go.
