Exosomes are, without doubt, the buzzword of the moment in aesthetics. Search the term on social media and you’ll find glowing before and after photos, bold promises of “stem cell regeneration”, and “exosome facials” advertised at anything from a couple of hundred pounds to well over £500 a session, often as an add-on to microneedling or laser.
Some of that excitement is justified, because the science behind exosomes is genuinely interesting. Some of it is marketing running well ahead of the evidence, and some of it, frankly, is happening outside the law. So let me explain what exosomes actually are, what the research does and doesn’t show, what is legal in the UK, and how to tell a sensible treatment from a risky one.
What Is Exosome Therapy — And Why Is Everyone Talking About It?
What Are Exosomes?
Exosomes are tiny bubbles, far too small to see even under an ordinary microscope, that cells release to communicate with one another. Think of them as the body’s text messages. Each one carries a small parcel of proteins, growth factors, lipids and genetic material, and when it reaches a neighbouring cell, it delivers instructions: repair this, calm that inflammation down, make more collagen.
That signalling role is exactly why the aesthetics world is so interested. Rather than adding something to the skin, as a filler does, the idea is to send the skin’s own cells a message to behave more youthfully. It’s the same broad principle behind treatments I’ve used for years, such as PRP and polynucleotides, just working through a different messenger.
Why Is Everyone Talking About Them?
Partly because the results patients see after exosome treatment can be lovely: calmer, smoother, more even skin, and noticeably faster recovery after procedures like microneedling and laser. Partly because the word itself sounds futuristic and slightly miraculous, which social media adores. And partly because exosomes have been heavily promoted in Korea and the United States, and the trend has travelled here, as these things always do.
The trouble is that “exosome” has become a label rather than a product. It’s used to describe everything from a well made, lab produced topical serum to an unregulated vial of human derived material imported from goodness knows where. Those are not remotely the same thing, and patients are rarely told the difference.
What Does The Evidence Actually Say?
The early research is encouraging. Small studies of exosomes combined with microneedling suggest improvements in texture, fine lines, pigmentation, hydration and acne scarring, and there is promising work in hair thinning too. I’ve seen genuinely good results in clinic, particularly in skin that’s reactive or slow to heal.
But the studies are still small, the products vary enormously, and long term data is thin. Reviews published this year describe the approach as promising while calling for larger, longer and better controlled trials. So when I see exosomes advertised as a “miracle” or a replacement for everything else, I roll my eyes. They’re a useful addition to a good treatment plan, not a magic wand.
The Part Nobody Tells You: What’s Legal In The UK
This is where I’ll probably upset a few people in my own industry. The MHRA, our medicines regulator, treats injected exosomes as medicinal products, and no injectable exosome product has a UK marketing authorisation. In plain English, injecting exosomes into the skin, under the skin or into a vein for aesthetic purposes is not lawful in this country. Exosomes derived from human tissue, often sold as “stem cell exosomes from donor tissue” or umbilical cord material, are not permitted for cosmetic use at all.
Despite this, injected and human derived exosome treatments are still being advertised in the UK, often as a premium “luxury upgrade”, and patient safety organisations such as Save Face have issued public warnings about them. The concern is a practical one. With an unregulated product, neither the patient nor the practitioner can be certain what is in the vial, how it was made or whether it is sterile. In the United States, where no exosome product is approved either, the FDA has warned about serious adverse events, including infections, linked to unapproved exosome products. That is exactly the kind of risk regulation exists to prevent.
My view is simple. If a clinic can’t tell you exactly where its exosomes come from, how they’re applied and show you the product documentation, don’t let them near your face.
Exosome Treatment At Our Clinic
In clinic, I use exosomes topically, never injected, and only products from non-human sources with proper documentation behind them. They’re applied to the skin immediately after microneedling or certain laser treatments, when tiny channels in the skin allow them to reach the layers where they can do their work.
I find exosome treatment particularly useful for:
- Dull, tired or uneven skin that needs a genuine boost in texture and radiance
- Fine lines and early laxity, as part of a wider collagen building plan
- Acne scarring, alongside microneedling
- Faster recovery after resurfacing, with less redness and a shorter pink stage
- Sensitive or reactive skin that tolerates more aggressive treatments poorly
Most patients need a course of three sessions, around four weeks apart. Downtime is usually 24 to 48 hours of mild redness, often less than with microneedling alone. Results build gradually, typically showing from four to six weeks as the skin repairs and renews itself.
Exosomes Versus Polynucleotides And PRP
I’m often asked which is “best”, and my honest answer is that it depends on your skin. Polynucleotides have a stronger evidence base and remain my first choice for thin, sun damaged skin and under eye concerns. PRP uses your own blood, which some patients love and others find off putting. Exosomes sit comfortably alongside both, and are my go to when someone wants faster healing and a real improvement in skin quality from a microneedling course. They complement each other rather than compete.
Questions To Ask Before You Book
- Where does the exosome product come from? Human derived is a firm no.
- Will it be applied to the skin or injected? Injected is another firm no.
- Can you show me the product documentation?
- Who is carrying out the treatment, and are they medically qualified?
- What results can I realistically expect, and over what timescale?
A confident, specific answer to each of these is a good sign. Vague reassurance is not.
Is Exosome Therapy Worth It?
For the right patient, done properly and legally, yes. It’s one of the more exciting additions to regenerative skincare, and I’ve been pleased with what I’ve seen in clinic. But it deserves to be treated as a genuine medical treatment, not a social media trend, and chosen because it suits your skin rather than because it’s fashionable this month.
If you’re curious about exosome treatment, or you’re simply not sure whether it’s right for you, do get in touch with the clinic to book a consultation. We’ll look at your skin together and work out whether exosomes, or something else entirely, will genuinely give you the result you’re hoping for.
