The treatment is โ€˜spray-onโ€™ skin, created with a postage stamp-sized piece of the patientโ€™s own skin.

It is placed in a battery-powered device the size of a lunchbox in a special solution containing enzymes that make the cells proliferate โ€” within half an hour this creates enough โ€˜spray-onโ€™ skin to cover an adult male torso.

The technology can help burns victims heal without painful skin grafts and without unsightly and uncomfortable scars.

However, itโ€™s not widely available on the NHS.
