A university student who suffered severe facial burns has remarkably healed thanks to what is being called a world-first biological treatment.
On December 2, 2025, 18-year-old Kaitlyn Jeffrey was caught in a fire at the Pi Kappa Alpha frat house at Western University in Canada. The fire was caused after rubbing alcohol had been thrown onto a lit torch. Kaitlyn was one of the five people rushed to the hospital for injuries. She suffered serious burns after her face and hair had been set ablaze.
A new treatment
Usually, treatment for such burns would require a skin graft, but the burn unit at Hamilton Health Services wanted to try something different. While skin grafting is helpful, the end result isn’t always ideal. Skin grafting can be a slow process that ends with scarring and often a patch-like appearance on the patient.
“My vision for Kaitlin was to avoid skin graft surgery to her face and neck at any cost,” said Dr. Marc Jeschke, medical director of the hospital’s regional burn program and vice-president of research and innovation at HHS. “You can do the best graft on the planet, but you won’t return the skin to normal.”
With Kaitlyn’s and her family’s permission, Dr. Jeschke sent an urgent application to Health Canada for a new type of treatment. After Health Canada approved, the doctors proceeded to give Kaitlyn an exosome treatment for her facial burns. The results were a rousing success.
What are exosomes?
Exosomes, or extracellular vesicles (EcVs), are present in almost all cells, tissues, and body fluids. They’re tiny vesicles released naturally by nearly all types of cells, carrying proteins, lipids, and genetic material. They essentially carry these “packages” of material and send signals from one cell to another to regulate their behavior. They’re not only being tested for medical applications like this one, but are a part of a skin care trend as well. While exosomes had been studied for burn research, they haven’t been tested on humans before.
One trillion exosomes were collected and injected into Kaitlyn’s injured areas over the course of two treatments. This helped her cells coordinate in rapidly healing and repairing her facial tissue. The treatments also significantly reduced inflammation.
Astounding healing and new possibilities
After she had healed, Katilyn was amazed and grateful at the result.
“It’s honestly a miracle,” she said. “Being injured in the fire has also had a deep impact on my mental health, and it’s something I’m continuing to deal with. But having such good results, particularly to my face, is helping me move forward.”
Exosomes are still being researched for other potential medicinal applications. They are being tested to see how well they could modulate immune responses and deliver biomarkers. This could help combat cardiovascular disease, neurological disorders, and cancer among other ailments. Time and research will tell whether exosomes can help those patients like they helped Kaitlyn.
