Explainer / What is exosome therapy – and how does it work? The new beauty trend promises radiant skin, voluminous hair and reduced inflammation, but more research still needs to be done

- Exosomes are microscopic vesicles within our cells that are said to offer regenerative benefits and promote collagen production when used in cosmetic treatments – ideal for anti-ageing treatments
- It’s still emerging for now, but exosome therapy could stimulate cellular regeneration in the skin and scalp to create a youthful complexion and thick, healthy hair
Exosomes are taking over beauty studios and clinics around the world, with the tiny, nano-sized particles gaining popularity for their remarkable regenerative and anti-inflammatory properties.
But what exactly are exosomes – and how do these therapies work?
What are exosomes?

Exosomes are microscopic vesicles within our cells that are filled with important genetic material; these are released into the surrounding environment to transport vital information between cells. “[Exosomes] play an important role in cellular communication,” says Dr Ahmad Chaudhry, dual board-certified dermatologist at Scandinavian Biolabs. “Exosomes are small vesicles secreted by stem cells and other cell types that contain cargo such as proteins, lipids and nucleic acids.”
“They function like little delivery trucks, transporting these materials from one cell to another and merging with the recipient cells to deliver their cargo. This process can alter the functioning of the receiving cells, which is crucial for cellular communication and health,” adds Nicole Ho, cosmetic chemist and lab manager for Genie Supply.
What are the benefits of exosome therapy?

Exosomes work their magic in skincare through a process called endocytosis, where the target cell consumes the exosome. Once inside, the exosome’s cargo – proteins, lipids and nucleic acids – is released, triggering a cascade of cellular responses.
