My whole body suffers from dry skin every winter.

My skin is so dry that I always dread the arrival of the season when the cold winds start blowing. I am bothered by dead skin cells not only on my face but also on the backs of my hands, stomach, and especially on my heels. Even though I apply cream generously and frequently, they flake off and turn white within just a few hours. Because my makeup looks cakey, I often cover my face completely with a scarf or muffler. The worst part is the dead skin on my heels. It builds up so thickly that I've even tried filing it off with a stone, and I've tried every cream and scrub that's supposed to be good, but nothing works. When my heels touch my clothes, that area leaves white stains, looking like chalk. I really want to know how to deal with dead skin cells...
