Being extremely sensitive to further injury and iritation, how do I wash myself?

The skin's been getting a bit flakey and there's a thin layer of dead skin, and I worry it might be reducing the effectiveness of my medication. I've tried picking and gently scraping it off with a nail, and even gone surgical with a pair of tweezers, but it keeps causing more irritation that pops up painfully hours later. I'd use soap, but if it sticks to the skin then I have to rub it off and that causes issues too. I was thinking maybe there's some sort of topical solution that i could just leave on and it would lift up all the dead skin somehow so I could gently rinse it off, but I guess that's a bit hopeful.
