Scaly Skin

Went home yesterday to visit my son. Later in the evening, went home to my father's house to clean the house as my sister didn't go there for more than 2 weeks already. Well, my father is not a good cleaner. I took me nearly 3 hours just to sweep& mop the floor, clean the toilet and wipe the furniture in the hall. My father is a PRP patient, so he has scaly skin as photos showed below. That's the amount of peeling off skin in the hall.
