The useful comparison is not which treatment is best. It is what each one physically does, what regulatory status it holds, and how strong the evidence behind it is. On those three axes the options separate clearly.
Microneedling alone and topical actives are the two comparisons most often left out of a consultation, and they are the two that matter most, because one is inside every exosome protocol and the other is better evidenced than anything in the room.
Comparisons in aesthetics usually get made on outcome claims, which is the least reliable basis available. This page compares on three things that can actually be checked: what the treatment physically does, what regulatory status it holds, and how good the evidence is.
The comparison
| Option | What it physically does | UK regulatory status | Evidence base | Best suited to | Visible downtime |
|---|---|---|---|---|---|
| Exosome preparation with microneedling | Delivers a vesicle preparation through channels made by needling | No marketing authorisation for this use | Early, mostly laboratory and animal, small human studies | Skin quality, post procedure recovery, adjunct in hair loss | Two to three days of visible redness |
| Microneedling alone | Controlled micro injury triggering a wound healing and remodelling response | Regulated medical device | Reasonable for texture and some scarring | Texture, pores, some scarring | Two to three days of visible redness |
| Platelet rich plasma | Concentrated platelet fraction from your own blood, injected or applied | No marketing authorisation for these indications | Moderate, small studies, mixed protocols | Hair loss adjunct, skin quality | One to three days, bruising possible |
| Polynucleotides | Purified nucleotide chains injected into the dermis | No marketing authorisation for aesthetic indications | Developing, small and product specific | Skin quality, hydration, increasingly hair | Bumps for hours to a day, bruising possible |
| Topical minoxidil | Prolongs the growth phase of the hair cycle | Licensed in the UK for androgenetic alopecia | Large trial base over decades | Androgenetic alopecia | None, but must be continued indefinitely |
| Prescription retinoid | Increases cell turnover and stimulates dermal collagen | Licensed medicine | Deep and long standing for skin texture and fine lines | Texture, fine lines, tone | Irritation while the skin adjusts |
Microneedling on its own
This is the comparison a consultation is least likely to offer, and the one that matters most, because a microneedling treatment sits inside every exosome protocol. It has an evidence base for improvement in skin texture and in some scarring, it uses a regulated medical device, and it costs less.
If you have never had needling, having it alone first is a defensible plan. You find out how your skin responds, what the downtime is like for you and whether the result is enough, before adding an unquantified and expensive variable. If it is not enough, the conversation about adding something is better informed.
Platelet rich plasma
Blood is drawn, spun to concentrate the platelet fraction, and the resulting plasma is injected or applied after needling. The rationale is the same family of argument: growth factors and signalling molecules encouraging repair.
Its practical advantage is provenance. What is administered came out of your arm twenty minutes earlier, which removes an entire category of question about the vial. Its practical disadvantages are that it requires a blood draw, that content varies with your own physiology and the system used, and that it is not licensed for these indications either. Its published literature is larger than that for exosome preparations and includes randomised work, though it shares the same limitations of small samples and inconsistent protocols.
Polynucleotides
A different category again: purified nucleotide chains, typically injected into the dermis, offered for skin quality and increasingly for hair. The proposed mechanism is a mixture of hydration, a mild stimulatory effect on fibroblasts and a modulating effect on inflammation.
They are usually injected rather than delivered through needling, which changes the practical experience and the risk profile. They are not licensed as medicines for aesthetic indications in the UK. The literature is developing and, as with the rest of this field, is characterised by small studies and product specific results. The point of including them here is that clinics sometimes present one of these categories as the regulated option and another as the unregulated one, and that framing does not survive checking.
Topical actives and the licensed options
The unglamorous comparison, and the one with the best evidence in the room.
For skin
- Daily broad spectrum sunscreen, the best evidenced intervention for skin appearance over time.
- A retinoid, the best evidenced topical for texture and fine lines, available over the counter in lower strengths and by prescription in higher ones.
- Treating any active condition first. Rosacea and acne need managing before a course of needling, not during one.
For hair
- Topical minoxidil, licensed in the UK for androgenetic alopecia and available without prescription.
- Oral finasteride, a prescription only medicine licensed for men in the UK and not licensed for women, which needs a proper prescribing discussion.
- A diagnosis before anything else. Not all hair loss is androgenetic, and several causes need entirely different management.
None of these is being compared here as a rival product. They are the baseline against which any clinic treatment should be measured, and the baseline a clinic has no commercial reason to raise.
Choosing by concern rather than by treatment
| If your main concern is | The usual first choice |
|---|---|
| Overall skin ageing with no routine in place | Sunscreen and a retinoid, consistently, before any clinic treatment is considered |
| Texture and enlarged pores | Microneedling alone is the reasonable first clinic treatment |
| Acne scarring | Assessment by a dermatologist first, since scar type determines the treatment |
| Volume loss or tissue descent | Neither exosomes nor needling. This is a different category of treatment |
| Early androgenetic alopecia | The licensed options first, with a diagnosis established beforehand |
| Advanced hair loss with smooth scalp | Surgical assessment. Medical treatments do not restore lost follicles |
| Sudden or patchy hair loss | Diagnosis before treatment. Several causes need entirely different management |
| Recovery after laser or a peel | A reasonable place to consider a preparation, if the claim and price are modest |
The pattern in that table is worth noticing. For several common concerns the sensible first choice is not a clinic treatment at all, and for hair loss specifically it is a licensed medicine. Exosome therapy appears as a reasonable consideration in a narrow band: skin quality where the foundations are already in place and needling alone has been tried or considered, and post procedure recovery where the claim is modest and the price is proportionate.
Once you have narrowed it down, the cost page gives the 2026 ranges and the consultation checklist gives you the twelve questions to take with you.
Common questions
Exosomes or platelet rich plasma
Both sit outside the licensed medicine route for these indications and both are sold as courses. Platelet rich plasma is prepared from your own blood at the appointment, which removes the question of what is in the vial but introduces variability from your own biology and the preparation system. Exosome preparations are supplied by a third party and cannot be verified by you. Neither has evidence strong enough to declare a winner.
Exosomes or polynucleotides
Polynucleotides are a different category, usually injected rather than applied topically, with their own developing literature. They are not a licensed medicine for aesthetic indications in the UK either. If a clinic presents one as regulated and the other as not, ask them to be specific about what regulatory status each actually holds.
Is microneedling on its own a reasonable choice
It is the comparison most worth taking seriously, because it is the treatment inside every exosome protocol. It has its own evidence base for skin texture, it costs less, and it isolates the variable. Asking a clinic for the price of microneedling alone alongside the combined price is the single most clarifying question on this page.
Where do topical actives fit
At the foundation, before any clinic treatment. Sunscreen and a retinoid have a deeper evidence base for skin appearance than any of the treatments compared here, cost a fraction as much, and work every day. For hair, minoxidil is licensed for androgenetic alopecia and available without prescription. None of these are exciting, which is why they are underrepresented in consultations.
How do I choose
Start from the concern rather than the treatment. Match the concern to what each option physically does, rule out anything whose mechanism does not address it, then compare what is left on regulatory status, evidence quality and total cost including maintenance. The table on this page is arranged to make that possible.
