Exosomes are nano-sized extracellular vesicles — tiny biological messengers secreted by cells — that carry proteins, lipids, and genetic material (including microRNA and mRNA) between cells. In aesthetics, exosome preparations derived from stem cells (typically plant-derived or human mesenchymal stem cells) are applied topically or injected to deliver billions of these cellular signals directly to the skin, dramatically accelerating repair, reducing inflammation, and stimulating collagen production.
Exosome therapy represents the cutting edge of regenerative aesthetics. Unlike PRP (which uses your own blood), exosome preparations are manufactured products with a standardised, concentrated dose of growth factors and signalling molecules. They are most commonly used after procedures such as microneedling, laser resurfacing, or Morpheus8 to accelerate healing and enhance results.
Exosomes are not yet regulated as a standalone treatment in England and the evidence base, while promising, is still emerging. The quality of exosome products varies significantly between manufacturers. Ensure your practitioner uses a reputable, well-characterised exosome product and can explain the source, concentration, and storage requirements.
The exosome market is largely unregulated, and product quality varies enormously. Some products marketed as "exosomes" contain very few actual exosomes. Ensure your practitioner uses a product with published evidence of its exosome concentration and biological activity. As with all injectables, there is a risk of infection and allergic reaction.
| Region | Topical (with microneedling) | Injectable |
|---|---|---|
| London | £300–£600 | £400–£800 |
| South East | £250–£500 | £350–£700 |
| Midlands | £200–£400 | £300–£600 |
| North West | £200–£400 | £300–£600 |
| Yorkshire | £180–£380 | £280–£550 |
Ask your practitioner specifically which exosome product they use, the source of the exosomes, and the evidence base for the product. Be cautious of clinics offering exosome treatments at very low prices, as this may indicate a low-quality product.
