Skin Disorders?

I have a skin condition called psoriasis. Are there any tips that I could use from others who may have the same issue or similar issue?
Basically, my entire shave able region has psoriasis, but comes and goes with the seasons(in the summer I have more sunlight which mitigates the symptoms).
If anyone has a technique they could throw my way, I'd surely appreciate it.
Cheers,
Sean

I hear Grandpa's Pine tar works well for various skin conditions.. I have heard of fellows using it to shave.. Maybe even Tea Tree..
