Many astronauts return from space complain of skin problems. European and American space Agency decided to look into this issue and asked scientists to examine how space travel affects the skin. It turned out that the outer layer of skin astronaut loses 20% of the thickness after spaceflight.

To the conclusion reached by Professor Karsten Koenig from the Department of Biophotonics and laser technology of the University of Saarland in Germany. The Professor studied the skin of the three astronauts before and after spaceflight by a method of multiphoton tomography and showed a high production of collagen, the effect of aging in the lower layer of the skin, the reduction of the upper layer by 20%, Reuters reports.

having identified the problem, scientists are going to continue to study further, to prevent the effect of reducing the skin in long-term human expeditions to Mars, which will take a year or two time. Because the reduction of the epidermis 20% occurred in just 6 months the astronauts in orbit.
