Living in space could thin our skin

It is not bizarre to say aging in space is an entirely different experience than aging on Earth. Bones lose density and muscles atrophy. Yet, how does living inside the International Space Station, traveling at speeds more than 32,000 kilometers per hour, actually affect the skin? Researchers in Germany found that spending time in space makes the skin thinner, Reuters reports. They used a high-resolution skin imaging technique known as tomography to study recently returned astronauts. The technology allows them to look into the skin with a resolution a thousand times better than ultrasound. Astronauts also demonstrated strong production of collagen, a protein fiber that provides strength and elasticity to the skin. Although they do not have any explanation yet as to why their skin goes through these changes, ongoing research could be instrumental to preparing astronauts for longer missions.
