Try organic grass-fed beef or bison whipped tallow. Also called face & body butter tallow. No added oils. It doesn't smell. Little goes a long ways. Can be applied everywhere. It help the psoriasis itch as well as help the healing of the psoriasis patches for me. Excellence moisturizer too. I apply when needed. It softens & lighten the psoriasis patches for me also. I usually use it at night.
Best place to order is Esty. I hope this helps.

If it's moist during the active days, wash with Lume cleanser & add Lume cream deodorant & let dry. And use the tallow at night. You can use the cream deodorant everywhere, too.

Just Google Lume Deodorant.

I hope this helps you.
