This is about Dry Skin and the Immune Response connection.
I am a caregiver and have suffered with chronic P for 37 ointment filled years. I have four sons and one of them is seriously ill with P.
The doctor prescribed a very mild steriod in White Petrolatum and Mineral Oil for my son who is at about 50%.
This combination proved to be an effective WhiteOut. Stops flaking right now. The difficulty is that my son wanted nothing to do with steriods in the doctors mix. Decided to make it myself. It worked well but the mix is so wet that I wanted to sort out how to make a day treatment.
I started at: www.vaseline.com
What I found here is that dry skin -- with or without P. -- creates a significant logical immune response.

This is the best information that I have ever seen about what is going on with my skin. My original goal was to figure out a day cream so I moved on to collecting more information on occulsives and humectants at:
I googled vaseline psorasis and with interest read:
This is where I found out that I was using too much Vaseline.
Also about opening the pores with water.
My son suffers from "I don't want to do this every day". I think we have all been there at one point or another. I started doing this exact routine with him. The excellent news: 37 years later this is causing both of us to go into remission.
The best that I can figure is that in the case of P. eliminating the triggers that are firing the immune response in the first place is the best we are going to do for now.
When the medical teams can sort out a fix that has no side effects we will all be pleased. In the meantime: stay wet twice a day and get well like us.
