Exosome Therapy
In medical aesthetics, exosome therapy refers to using preparations of exosomes — nanoscale vesicles released by cells that carry signaling proteins, lipids, and RNA — most often applied to the skin to support recovery and calm redness after a resurfacing or microneedling procedure. It is an emerging and still evidence-limited category, and no exosome product is approved by the U.S. FDA for this use.

Overview
Exosomes are tiny vesicles that cells use to send signals to one another. Skincare and clinic products that contain or claim to contain them are typically used as a topical step during skin management — most commonly right after microneedling or laser treatment — with the goal of supporting barrier repair, easing post-procedure redness, and improving overall skin comfort. They are usually presented as an add-on to a procedure rather than a standalone treatment.
What exosome preparations can realistically do is still being studied, and marketing often runs ahead of the evidence. They are not a proven substitute for the medical treatment of a skin disease, and they differ from injectable options such as platelet-rich plasma or skin boosters, which are their own separate topics. Any promise of dramatic rejuvenation, guaranteed results, or a fixed number of days to “new skin” should be treated with caution.
How it works
The idea behind exosome therapy is that these vesicles carry molecular signals — proteins, lipids, and short strands of RNA — that may influence how surrounding skin cells behave, for example by dampening inflammation or supporting repair. Because vesicles are relatively large and healthy skin is built to keep such things out, products are generally applied when the barrier is temporarily open, such as immediately after microneedling or laser, or with a delivery device.
