Exosomes vs PRP — Which Is Better?
Exosomes or PRP: Which Is Better?
Both approaches aim at the same thing: prompting the skin to repair itself rather than adding an active that acts on it directly. They get there in very different ways, and their regulatory position is also very different.
PRP (platelet-rich plasma)
Category: Autologous blood product
Key Benefit: The patient’s own growth factors, no external material
Blood is drawn, spun in a centrifuge to concentrate the platelets, and reintroduced. The growth factors come from the patient, which removes questions of compatibility — but also means potency varies with the patient’s platelet count, age and health.
Exosomes
Category: Extracellular vesicles
Key Benefit: Consistent signalling cargo, no blood draw
Nanoscale vesicles that carry proteins and RNA between cells. Because they are manufactured to specification rather than harvested from the patient, their cargo is consistent from treatment to treatment and from patient to patient.
What regulations allow
This is where the comparison stops being purely clinical. PRP is an established autologous procedure carried out under the usual clinical supervision. Human and stem-cell-derived exosomes intended for injection are not authorised for aesthetic use, and practitioners should be wary of any offer of injectable human exosomes; if in doubt, check their regulatory status with the AEMPS (Spanish Agency of Medicines and Medical Devices).
Plant-derived exosomes are a different category and are used topically, typically applied immediately after a procedure that has opened channels into the skin: microneedling, RF microneedling or a peel. Every exosome product in the Skymedic range is plant-derived and formulated for topical application.
Head-to-Head Comparison
| Factor | PRP | Exosomes (plant-derived, topical) |
|---|---|---|
| Source | The patient’s own blood | Plant cell culture |
| Preparation | Blood draw and centrifugation in the same visit | None: supplied ready to apply |
| Consistency between sessions | Varies with the patient | Standardised per batch |
| Route | Injected or applied after microneedling | Topical, after the procedure |
| Needles required | Yes, for the draw | No |
| Typical course | 3 sessions, 4–6 weeks apart | Applied with each procedure, plus home use |
| Home continuation | Not possible | Yes, in serum format |
| Regulatory position | Established autologous procedure | Topical plant-derived use permitted; injectable human-derived products are not authorised |
When PRP makes sense
PRP remains a good choice where an autologous approach is specifically wanted, in hair protocols with a long evidence base, and for patients who prefer that nothing foreign is introduced. It requires consultation time, a centrifuge and a practitioner experienced in the draw.
When exosomes make sense
Exosomes suit clinics that want a consistent post-procedure step without adding a blood draw to the appointment, and patients who want to continue the same signalling approach at home between sessions. In practice this is the most common use: applied in clinic straight after microneedling, then continued as a daily serum.
Can you combine them?
Yes, and some protocols do: PRP for the injected component, and topical exosomes at the end of the session, continued at home. They are not competing mechanisms; they occupy different points in the same appointment.
Professional Verdict
PRP and topical exosomes answer different practical questions. PRP is the choice when the patient wants an autologous, injected treatment and the clinic is set up for it. Plant-derived exosomes are the choice when consistency, chair time and a credible at-home continuation matter more. The one thing not to do is treat injectable human-derived exosomes as an available option: they are not.
