Quick Answer
Exosome treatment is a regenerative aesthetic procedure in which extracellular vesicles measuring 30–150 nanometres — derived from stem cells — are applied to the skin or scalp. These nano-sized vesicles carry growth factors, cytokines, and mRNA, triggering repair and renewal processes in target cells. Treatment is delivered in 3–6 sessions, with the first noticeable results seen within 4–8 weeks; each session takes approximately 30–45 minutes. Please contact us for current pricing information.

What Is an Exosome?
Exosomes are extracellular vesicles secreted by all cells, enclosed within a double-layered lipid membrane. Their size ranges from 30 to 150 nanometres — making them approximately 1,000 times smaller than the diameter of a human hair.
Key characteristics of exosomes:
- They are paracrine signal carriers — they act as "messengers" in intercellular communication
- They contain bioactive molecules — they carry proteins, lipids, mRNA, and microRNA
- They reprogramme target cells — they can alter the behaviour of the receiving cell
- They are tolerated by the immune system — as vesicles rather than cells, the risk of rejection is low
- They can cross the blood-brain barrier — their nano size allows them to traverse tissue barriers
A simple analogy: Think of exosomes as "cargo packages" sent between cells. Each package contains instructions (mRNA) telling the recipient cell what to do, tools (proteins), and energy sources (lipids).
Contents of Exosomes
| Component | Function | Significance in Aesthetics |
|---|---|---|
| Growth factors (EGF, FGF, VEGF, TGF-β) | Cell proliferation and differentiation | Increases collagen synthesis |
| Cytokines | Immune response regulation | Provides anti-inflammatory effect |
| mRNA | Protein synthesis instruction | Initiates new protein production in the target cell |
| MicroRNA (miRNA) | Gene expression regulation | Can silence ageing-related genes |
| Proteins (CD9, CD63, CD81) | Cell recognition and fusion | Specific binding to the target cell |
| Lipids | Membrane integrity | Maintains vesicle stability |

How Does Exosome Treatment Work?
Unlike conventional treatments, exosome therapy works through a paracrine signalling mechanism. This process occurs in three phases:
1. Binding to the Target Cell
Exosomes bind to the membrane of the target cell via tetraspanin proteins (CD9, CD63, CD81) on their surface. This binding is specific, analogous to a key-and-lock mechanism.
2. Content Transfer
Once binding occurs, the exosome delivers its contents (growth factors, cytokines, mRNA) into the cytoplasm of the target cell. This transfer alters the cell's existing biological programme.
3. Cellular Response
Following the transfer, the following changes are triggered in the target cell:
- Collagen type I and type III synthesis increases (the foundation of skin elasticity)
- Fibroblast proliferation accelerates
- Glycosaminoglycan (including hyaluronic acid) production rises
- Angiogenesis (new vessel formation) is stimulated
- Anti-inflammatory cytokines are released
A split-face clinical study published in the Journal of Investigative Dermatology in 2025 reported that adipose mesenchymal stem cell-derived exosomes produced improvement in photoaged skin comparable to PRP, with histological confirmation of increases in collagen I and glycosaminoglycans.

Exosome Sources: Stem Cell-Derived or Plant-Derived?
The market offers exosome products from various sources. Source selection directly affects treatment efficacy.
Stem Cell-Derived Exosomes vs. Plant-Derived Exosomes
| Feature | Stem Cell-Derived | Plant-Derived |
|---|---|---|
| Source | Human mesenchymal stem cells (MSC) | Aloe vera, lemon, ginger, etc. |
| Growth factor content | High (EGF, FGF, VEGF, TGF-β) | Low or absent |
| mRNA transfer | Yes — compatible with human cells | Limited — cross-species incompatibility |
| Level of clinical evidence | Moderate–high (RCT studies available) | Low (mostly in vitro) |
| Paracrine effect | Strong | Weak |
| Price | High | Low–moderate |
| Regulation | Under strict oversight | Classified as cosmetic |
| Recommended use | Medical aesthetic procedures | Supportive skincare |
Expert note: For clinical-grade skin rejuvenation and hair treatment, stem cell-derived exosomes should be preferred. Plant-derived exosomes may be used as supportive agents in cosmetic skincare products but cannot substitute medical procedures.

Exosome Treatment vs. PRP: A Comprehensive Comparison
| Criterion | Exosome Treatment | PRP Treatment |
|---|---|---|
| Source | Stem cell exosomes produced in a laboratory | Platelet concentrate derived from the patient's own blood |
| Growth factor concentration | Very high and standardised | Variable (dependent on the patient's blood values) |
| Blood draw required | No | Yes (10–20 mL of blood drawn) |
| Procedure duration | 30–45 minutes | 45–60 minutes (including centrifugation) |
| Number of sessions | 3–4 sessions (every 4–6 weeks) | 3–6 sessions (every 2–4 weeks) |
| Time to first results | 2–4 weeks | 4–6 weeks |
| Peak effect | 3–6 months | 6–12 months |
| Allergic reaction risk | Very low | None (autologous material) |
| Standardisation | High (controlled production) | Low (varies by individual) |
| Level of scientific evidence | Emerging (RCT studies increasing) | Strong (decades of data) |
| Combined use | Can be combined with PRP | Can be combined with exosomes |
Clinical findings: According to a 2025 investigator-blinded split-face study, exosome and PRP treatments produced similar levels of improvement in wrinkles, pigmentation, erythema, tissue texture, and overall skin appearance. The advantage of exosomes is that they offer a shorter procedure time since no blood draw or centrifugation is required.

| Contents | Bioactive vesicles (growth factors, mRNA) | Vitamin cocktails, hyaluronic acid, antioxidants |
| Depth of effect | Cellular-level tissue renewal | Nutritional and hydration support |
| Collagen production | Direct stimulation (fibroblast activation) | Indirect support |
| Session frequency | Every 4–6 weeks, 3–4 sessions | Every 2–4 weeks, 4–10 sessions |
| Duration of effect | 6–12 months | 3–6 months |
| Side effects | Minimal (mild redness) | Mild redness, bruising |
---
Exosome Treatment vs. Youth Vaccine (PDRN/Polynucleotide)
| Criterion | Exosome Treatment | Youth Vaccine (Salmon DNA, PDRN) |
|---|---|---|
| Mechanism of action | Cell renewal via paracrine signalling | DNA repair and polymerase activation |
| Source | Stem cell exosomes | Salmon fish DNA (polynucleotides) |
| Collagen synthesis | Strong stimulation | Moderate stimulation |
| Anti-ageing effect | Cellular-level rejuvenation | Tissue repair and hydration |
| Application method | Microneedling, mesogun, topical | Intradermal injection |
| Number of sessions | 3–4 sessions | 3–4 sessions |
| Combined use | Can be combined with youth vaccine | Can be combined with exosomes |
Expert recommendation: Since exosome treatment and the youth vaccine work through different mechanisms, they can be used together in combined protocols. This combination achieves both cellular renewal and DNA repair, creating a synergistic effect.

Exosome Treatment for Hair Loss
Exosome treatment shows promising results in the treatment of androgenetic alopecia (hereditary hair loss) and telogen effluvium (stress-related shedding).
Mechanism of Action on Hair
- Activates dermal papilla cells — stimulates the growth centre of the hair follicle
- Extends the anagen phase — increases the active growth duration of hair
- Activates the Wnt/β-catenin pathway — the key signal for hair follicle renewal
- Improves scalp microcirculation — increases blood flow via VEGF
- Reduces inflammation — slows follicular miniaturisation
Expected Results in Hair Treatment
- First 2–4 weeks: Noticeable reduction in hair shedding
- 4–8 weeks: Thickening of existing hair shafts
- 2–3 months: Start of new hair growth
- 4–6 months: Noticeable increase in hair volume
A systematic review (PMC, 2025) found that exosome treatment demonstrated efficacy in hair loss comparable to minoxidil and PRP, though larger-scale randomised controlled trials are needed.

How Is Exosome Treatment Applied?
Exosome treatment can be delivered via three different application methods:
1. Microneedling + Exosomes (Most Common Method)
Application steps:
- The treatment area is cleansed and disinfected
- Topical anaesthetic cream is applied (20–30 minutes waiting time)
- Micro-channels are created in the skin using a dermapen or microneedling device
- Exosome solution is applied over the micro-channels
- Exosomes penetrate the deeper dermis through the micro-channels
- Treatment is completed with a soothing mask
Advantage: The controlled micro-injury created by microneedling increases exosome absorption by 300–400% and also provides its own collagen induction benefit.
2. Mesogun Injection
- Exosome solution is injected intradermally using a mesotherapy gun (mesogun)
- Injection depth is adjusted between 0.5 and 2 mm
- Provides more controlled dosage and distribution
- Frequently the preferred method for hair treatment
3. Topical Application
- Applied topically to open channels after laser or microneedling
- Topical application alone is less effective due to limited penetration
- Generally used as an adjunct to other methods
---
How Many Sessions Are Required?
The treatment protocol varies according to the area being treated and the severity of the concern:
| Indication | Recommended Sessions | Session Interval | Maintenance Treatment |
|---|---|---|---|
| Mild skin rejuvenation | 3 sessions | Every 4 weeks | 1–2 sessions per year |
| Moderate–advanced ageing signs | 4–6 sessions | Every 4–6 weeks | 1 session every 6 months |
| Acne scars | 4–6 sessions | Every 4 weeks | As needed |
| Hair loss (mild) | 3–4 sessions | Every 4 weeks | 1 session every 6 months |
| Hair loss (moderate–advanced) | 5–6 sessions | Every 3–4 weeks | 1 session every 3–4 months |
| Scar treatment | 4–6 sessions | Every 4–6 weeks | As needed |

Frequently Asked Questions (FAQ)
1. Is exosome treatment painful?
Because a topical anaesthetic cream is applied before the procedure, no significant pain is felt during treatment. A mild stinging or tingling sensation may occur. Additional local anaesthesia can be administered for patients with a low pain threshold.
2. Is exosome treatment permanent?
Exosome treatment is not permanent but provides a long-lasting effect. The effect of a single treatment course can last 6–12 months. Results can be maintained with 1–2 maintenance sessions per year. Periodic care is recommended as the natural ageing process continues.
3. What is the key difference between exosome treatment and PRP?
The fundamental difference is the source: PRP is derived from the patient's own blood, whereas exosomes are produced from stem cells in a laboratory setting. Exosomes contain a standardised, high concentration of growth factors, while PRP content varies according to the individual's blood values.
4. When will results be seen after exosome treatment?
Improvements in skin brightness and firmness begin to be noticeable within 1–2 weeks. Collagen renewal and significant rejuvenating effects emerge within 2–4 months. Maximum results are generally assessed at 4–6 months.
5. Can exosome treatment replace a hair transplant?
No, exosome treatment cannot replace a hair transplant. Exosomes strengthen existing hair follicles and thicken thinning hair, but cannot generate new hair growth in completely dead follicles. They can be used as a complementary treatment to accelerate recovery after a hair transplant and to improve graft survival rates.
6. Who should not undergo exosome treatment?
Individuals with an active cancer diagnosis, those who are pregnant or breastfeeding, those with an active skin infection, and individuals under 18 years of age should not undergo exosome treatment. People with autoimmune diseases must obtain specialist approval beforehand.
7. Can exosome treatment and mesotherapy be done together?
Yes, exosome treatment and mesotherapy can be applied together in combined protocols. While mesotherapy provides vitamin and mineral supplementation to the skin, exosomes initiate cellular-level renewal. This combination can create a synergistic effect.
8. Where else on the body can exosome treatment be applied besides the face?
Exosome treatment can be applied to many areas of the body, including the neck, décolletage, backs of the hands, scalp, wound scars, and stretch marks. It is also used in orthopaedic joint treatments.
9. Is exosome treatment safe?
When performed at certified healthcare facilities using traceable, quality-controlled products, exosome treatment is generally considered safe. The risk of serious side effects is low. However, treatments carried out in non-clinical settings or with products of unknown origin can lead to serious complications such as granuloma formation and infection.
10. At what age should exosome treatment be started?
Exosome treatment for preventive purposes can be initiated from the age of 25–30. For visible signs of ageing, patients aged 35 and above represent the most common group. In hair loss treatment, the stage of hair loss is more determining than age.
11. Can you go out in the sun after exosome treatment?
After treatment, it is recommended to avoid direct sunlight for at least 1 week and to use SPF 50+ sunscreen. When combined with microneedling, the skin barrier is temporarily weakened, increasing sensitivity to UV damage.
12. Is exosome treatment covered by insurance?
As exosome treatment is currently classified as an aesthetic procedure, it is not covered by public health insurance or private health insurance. The cost of treatment is borne by the patient.
13. Is there a quality difference among the exosome products used?
Yes, significant quality differences exist. Products manufactured in GMP-certified laboratories with a traceable source and backed by scientific studies should be preferred. The exosome concentration, growth factor profile, and storage conditions of the product directly affect its efficacy.
14. What is the difference between exosome treatment and a youth vaccine (PDRN/polynucleotide)?
Exosome treatment works through cellular reprogramming (paracrine signalling), whereas a youth vaccine (salmon DNA/PDRN) activates DNA repair mechanisms. Because they have different mechanisms of action, they complement each other when used in combination.
