Microscopic cells are the body’s building blocks. It takes about 100 trillion of them to make up one adult.
Like all other cells, skin cells are constantly being replaced. Roughly 30,000 to 40,000 dead skin cells flake off invisibly every minute. They have to make way for an equal number of fresh ones the body is producing. In fact, about 28 days from now, you will have a completely new skin! But when these dead layers pile up and don’t shed, they create calluses, warts, and thick white skin flakes of psoriasis (suh-RI-uh-sis).
