The skin gun is real, and it's here to heal.
Dr. Jörg C. Gerlach developed the gun, which uses a patient's own cells to help regenerate a burn victims' skin. The gun, which was conceptually discussed by PopSci in 2008, has been successfully used to treat over a dozen patients over so far, according to the National Geographic video below.
And the recovery time is amazing. The example in the video below shows a somewhat miraculous recovery, curing a second degree burn in just 4 days.
The clip below will also air on National Geographic's Explorer: How to Build a Beating Heart.
WARNING: The video below contains some graphic images of burns that are not necessarily for everyone. We don't suggest watching if you have a weak stomach.
