There’s a trendy new cure-all in town—you might have seen ads pop up on social media or read rave reviews in beauty magazines. Exosomes are being touted as a miraculous treatment for hair loss, aging skin, acne, eczema, pain conditions, long covid, and even neurological diseases like Parkinson’s and Alzheimer’s. That’s, of course, if you can afford the price tag—which can stretch to thousands of dollars.
“They’re magic!” claims one YouTube review. One US clinic exhorts: “Unlock the fountain of youth with exosome therapy.” “All aspects of skin health improve with exosome therapy,” states one UK clinic’s website, adding that “this is as cutting-edge as it gets.” Exosome particles could be used to treat “any inflammatory disease you could think about, which is almost all of them,” the founder of an exosome company says in a video on YouTube.
But there’s a big problem with these big promises: We don’t fully understand how exosomes work—or what they even really are.
It’s not clear why exosomes are taking off now. “It’s not as though there’s an overwhelming amount of safety and efficacy data,” says Turner. “I think it might be more of a buzz kind of phenomenon. This seems to be kind of a moment for exosomes.”
