The Therapy of exosomes It is based on the use of small extracellular vesicles that cells naturally release to communicate with each other. These vesicles contain proteins, lipids and genetic material, and can serve as biological messengers to transmit signals to other cells, stimulating regeneration processes, tissue repair or immune modulation.
On their social networks, Juliana Awada He shared images of his rejuvenating treatment with this technique. As is customary, the former First Lady uploaded photographs of her with an outstanding look to her profile, posing inside a space at the cosmetic clinic. The wife of Mauricio Macri He usually has extensive activity in virtuality, a few months ago he shared a reel presenting his own line of wines. But, in this particular case, her Instagram post focused on aesthetic health.
According to several specialists, among its alleged advantages, exosome therapy would avoid the risks associated with cell transplants, such as inadvertent tumor formation or immunological rejection. Furthermore, its action can be relatively fast and less invasive. These organisms, being derived from mesenchymal stem cells, have been shown to promote tissue regeneration, promote collagen production, accelerate healing, reduce inflammation and improve skin quality, firmness, hydration and tone.
However, experts warn that exosome therapy remains experimental and lacks established regulation. In particular, the US Food and Drug Administration (FDA) states that currently there is no approved exosome-based product for medical or cosmetic use. Unregulated use carries significant risks, including the possibility that exosomes from diseased cells stimulate unwanted cell growth.
Until now, the successes reported are mainly anecdotal or based on preliminary studies: improvements in healing, skin quality, recovery after injuries or aesthetic treatments, and promising results in tissue regeneration. But specialists agree that “there is no guarantee of permanent results” and that it should be interpreted as an experimental therapy with potential. The lack of standardization in its production makes it difficult to guarantee consistent efficacy between treatments.
A work published in January in the journal “Molecular Cancer” highlighted that exosomes can serve as “drug delivery vehicles” with “high biocompatibility and low immunogenicity”, ideal for concentrating treatments on tumor cells while minimizing off-target adverse effects. Likewise, in a preclinical study of periodontal regeneration collected in 2025, derivatives of mesenchymal stem cells were shown to improve bone and tissue markers, suggesting that they could promote dental and bone recovery.
A team from CONICET, through the firm ExoMas, reported in April of this year that exosomes released by brain stem cells managed to “increase the survival of neurons with signs of Parkinson’s” in cellular models, which opens a possible way to treat neurodegenerative diseases. Furthermore, in immunopathologies, a recent experiment with “engineered” exosomes reduced liver inflammation in a mouse model of autoimmune hepatitis, partially restoring immune tolerance.
In conclusion, exosome therapy is consolidated as a promising frontier of modern medicine. But, so far, its achievements—although auspicious—come mostly from preclinical studies or early phases, which implies that it is still an experimental option.
