Your body is built out of microscopic cells. About 100 trillion of them make up one adult.
Like all other cells, skin cells are always being replaced. Around 30,000 to 40,000 dead skin cells flake off every minute, but we don’t see them. They have to go, because the body is making an equal number of fresh ones. In fact, about 28 days from now, you will have a totally new skin! But sometimes these dead layers pile up and don’t shed. Then they create calluses, warts, and thick white skin flakes of psoriasis (suh-RI-uh-sis).
