Plastic surgeons at New York-Presbyterian/Weill Cornell Medical Center have turned the sunless tanning spray into an ‘internal Band-Aid’ that can seal the gaps that surgery leaves behind. It turns out the sugar-based molecules that turn you brown can be combined with a chemical to create a sticky gel bandage to help medical wounds heal better. The gel, composed of polyethylene glycol and a polycarbonate of dihydroxyacetone, is durable enough to stick to tissue, but also water soluble, so it won’t hang around forever.
