A group of young mice were sent to live aboard the ISS for 91 days, and we learned from their missions for months to follow. Apparently, at least for mice, weightlessness may lead to thinner skin and more hair growth. Excessive hair growth usually thickens the skin of mice, but the "astromice" showed the opposite. This may apply to humans too. A study on astronauts in the 1990s found that humans tended to suffer many minor skin injuries while spending prolonged periods in space.
