Hi..nix the soap totally...ESPECIALLY the one you're using.
I personally like Clinique DDML for lotion...used it for a very long time. I use Cetaphil cleanser.
But....since you have lots of problems with your skin, consider to use Cliniderm line...I would suggest the cream instead of the lotion...it will soothe, protect and help the rash. Not a lot of stuff in it.
You don't NEED toner considering the fragility of your skin...wait until it's cleared up completely.
