The video below demonstrates the skin cell gun which actually allows you to spray a new coat of skin onto your body. The technique involves taking adult stem cells from the patient, then spraying them onto the wound where they differentiate into skin cells. Since it is quite fast the risk of infection plummets, its quick, doesn’t leave scarring and doesn’t hurt. Unfortunately this only works with second-degree wounds so far, it has to be applied immediately after the burn and still remains an experimental procedure. RenovaCare, Inc. currently owns the technology.
