ReBellaXO is an exosome allograft derived from Wharton's Jelly MSCs and processed at a cGMP facility. Exosomes and other Extracellular Vesicles (EVs) are isolated from their parent cells and concentrated to produce the Exosomal Product. Exosomes are three times smaller than stem cells, which allows them to be used with small gauge needles and not lyse. They are a great cell free regenerative product option for all of your aesthetic procedure needs!
