While treatments like Botox and dermal fillers offer visible, short-term results, exosomes work differently—on a cellular level—stimulating the skin’s natural ability to regenerate, repair, and renew itself over time.
This innovative therapy is increasingly being integrated into advanced skincare protocols, offering patients a more biologically integrated, long-term solution to common skin concerns.
What Are Exosomes?
Exosomes are microscopic, membrane-bound vesicles naturally secreted by cells. Think of them as tiny messengers, delivering proteins, RNA, lipids, and other key molecules to help coordinate tissue repair, reduce inflammation, and trigger regeneration.
In aesthetics, exosomes used for clinical treatments are derived from carefully selected biological sources—including bovine colostrum, marine-based sources such as salmon, or plant-based materials. In some countries, human-derived exosomes are also used; however, UK cosmetic regulations currently allow only non-human sources for topical or injectable aesthetic use.
At Fitzrovia Clinic, we use Purasomes, a high-quality exosome product derived from bovine colostrum. Colostrum is naturally rich in growth factors, cytokines, and regenerative compounds, making it an effective and well-tolerated choice for promoting skin healing and renewal.
How Does Exosome Therapy Work?
When applied or injected into the skin, exosomes help rejuvenate tissue from within. They interact directly with skin cells—stimulating collagen production, calming inflammation, and accelerating cellular turnover.
Key benefits include:
- Cellular Regeneration: Promotes the repair of damaged or aged skin
- Collagen Stimulation: Improves skin firmness and elasticity
- Anti-inflammatory Action: Supports recovery and overall skin health
- Improved Tone and Texture: Results in smoother, brighter, more even-toned skin
Exosome therapy can be used alone or combined with microneedling, laser, or RF treatments to enhance results and speed recovery.
Exosomes vs. Polynucleotides: What’s the Difference?
Both exosomes and polynucleotides are powerful tools in regenerative aesthetics—but they work in distinct ways.
| Feature | Exosome Therapy | Polynucleotides |
| Source | Bovine colostrum, marine (e.g. salmon), or plant-based (non-human only in UK) | Extracted from fish sperm (typically salmon or trout) |
| Mechanism | Delivers proteins, lipids, and RNA to stimulate cell repair | Supports DNA and RNA repair to boost regeneration |
| Primary Benefits | Collagen stimulation, reduced inflammation, enhanced skin healing | Improved hydration, elasticity, and texture |
| Best For | Skin laxity, dullness, post-procedure healing | Fine lines, dry or crepey skin, early signs of ageing |
| Downtime | Minimal; mild redness or swelling may occur | Very minimal; occasional mild redness |
| Safety Profile | Excellent when using non-human sources (as per UK regulation) | Very safe and well tolerated |
Why Choose Exosome Therapy?
Exosome therapy is ideal for patients looking for a more holistic and regenerative approach to skincare. Rather than temporarily smoothing or filling, exosomes help restore healthy function to the skin, making it stronger, firmer, and more radiant over time.
It’s particularly beneficial for:
- Skin compromised by sun damage or inflammation
- Post-procedure recovery
- Ageing concerns like thinning or dullness
Conclusion
Exosome therapy is the future of advanced skin regeneration. By harnessing the skin’s innate ability to heal and renew, it offers a natural and effective alternative to more traditional cosmetic procedures.
If you’re curious about whether exosome therapy is right for you, we invite you to book a consultation at Fitzrovia Clinic. Our expert team will guide you through a personalised plan tailored to your skin’s needs—helping you achieve a luminous, healthier complexion with confidence.
