On Earth, our dead skin flakes simply fall to the ground. That's not the case in the low-gravity conditions aboard the International Space Station. The skin particles just float around, which is what prompts astronauts to change clothes in front of a filter inlet that sucks it up. Calluses fall off feet too, because there are no hard impacts when taking steps in low gravity to keep the dead skin of calluses on feet.
