Suntanner, heal thyself: Exosome therapy may enable better repair of sun, age-damaged skin

In the future, you could be your very own fountain of youth—or at least your own skin repair reservoir. In a proof-of-concept study, researchers from North Carolina State University have shown that exosomes harvested from human skin cells are more effective at repairing sun-damaged skin cells in mice than popular retinol or stem cell-based treatments currently in use. Additionally, the nanometer-sized exosomes can be delivered to the target cells via needle-free injections.
