Topical Human Mesenchymal Stem Cell-Derived Exosomes for Acceleration of Wound Healing Following Tissue Trauma and Aesthetic Procedures: A Case Series

Background: In the aesthetics practice, measures to accelerate wound healing and minimize downtime following procedures have been largely restricted to topical serums and platelet-rich plasma (PRP), which can have varying levels of success. Here, the authors present a case series of patients treated in clinical practice with cell-free exosomes derived from human placental mesenchymal stem cells (Exovex, Exocelbio, Doylestown, PA). Topical administration of exosomes after either aesthetic treatment or traumatic injury (a dog bite) had a marked effect on healing. Effects were assessed visually, and case-study images are shared. Individuals demonstrated significantly accelerated recovery and wound healing within hours to days, depending on the procedure. Patients who had undergone the same aesthetic procedure prior without exosomes reported satisfaction with reductions in pain, swelling, redness, and post-procedure downtime. No adverse events were reported by patients after treatment. Together, these case series suggest that exosome treatment can accelerate wound healing safely and effectively and support topical use in an office-based setting. These findings also highlight the need for more formal evaluation of the effects of exosomes on wound healing in reducing aesthetic procedure recovery times for surgical and non-surgical interventions.
