Exosome treatment in Singapore uses preparations of nanoscale cell-derived vesicles, applied to the skin after laser or microneedling or used on the scalp, as one part of a skin-quality or hair plan. This guide explains what exosomes are, how they are used in practice, and where the evidence and the regulatory position currently stand.
| Exosome preparations | PRP | Polynucleotides (e.g. Rejuran) | |
|---|---|---|---|
| What it is | Manufactured cell-derived vesicles | Concentrated platelets from your own blood | DNA-derived fragments |
| How used here | Topically after laser or microneedling; scalp | Not offered here (elsewhere: injected or applied after microneedling) | Injected as a skin booster |
| Evidence | Early, mostly small studies | More established, mixed results | Growing, mostly small studies |

Exosome treatment: quick answers
Do exosomes help acne scars?
Not on their own. Exosomes are used here as a topical step straight after fractional laser or RF microneedling, where small studies suggest they may support recovery. The scar itself is treated by the procedure chosen for its type, such as resurfacing, subcision or TCA CROSS. Exosomes are an adjunct to that plan, not a scar treatment.
What are exosome products made from?
Cosmetic exosome products are derived from stem-cell culture, plants or other sources and supplied as topical serums. Products differ in what the vesicles carry and how they are made, and commercial preparations are not yet standardised. Ask any clinic what the product is derived from and whether it is being applied or injected.
Are exosomes the same as polynucleotides or PDRN?
No. Exosomes are manufactured cell-derived vesicles, used here topically after laser or microneedling or on the scalp. Polynucleotides are DNA-derived fragments, injected as a skin booster. Both are discussed for skin quality, but they are different materials with different evidence, and one does not replace the other.
Is exosome treatment allowed in Singapore?
Exosome preparations are used topically here, applied to skin after laser or microneedling or to the scalp. Injected exosome products are a different regulatory question; this practice uses them topically.
Are exosomes better than PRP?
They are different. PRP comes from your own blood; exosome products are manufactured preparations of cell-derived vesicles. Comparative evidence is limited, and both are used as part of a wider plan rather than alone.
What can exosome treatment not do?
It does not lift sagging skin, replace volume or treat active disease on its own. It is used to support skin quality or the scalp alongside other treatments.
- What exosomes are
- Nanoscale extracellular vesicles carrying growth factors, cytokines and microRNA between cells
- Skin uses
- Post-laser recovery, photodamaged skin, texture and fine lines
- Hair use
- Topical application after laser or microneedling as one part of a hair loss protocol, alongside laser and medical treatment
- Exosomes vs PRP
- PRP comes from your own blood; exosomes are cell-derived vesicles from donor sources
- Not stem cells
- Exosomes contain no living cells and cannot divide
- Evidence
- Promising but early; products are not yet standardised and long-term data are limited
What Are Exosomes?
Exosomes are extracellular vesicles — nanoscale packages secreted by cells — that carry bioactive cargo including growth factors, cytokines, microRNA and signalling molecules. They function as intercellular messengers that modulate inflammation, tissue repair and regeneration.
Exosomes for Skin Rejuvenation
Applied to the skin after laser or microneedling, exosome preparations are proposed to support fibroblast activity, collagen synthesis, angiogenesis and skin regeneration. Applications include: post-laser recovery acceleration, photodamaged skin improvement, skin texture and luminosity enhancement, and fine line reduction.
“Both aim to deliver growth factors to target tissue. PRP uses the patient's own blood-derived platelets; exosomes use cell-derived vesicles from allogenic sources.”
Dr Sin YongOn exosomes versus PRP
Exosomes for Hair Loss
Topical exosome preparations applied to the scalp after laser are proposed to deliver growth-factor signals to hair follicles; the evidence is early. Dr Sin Yong applies exosomes topically after laser as a component of both male and female hair loss protocols — alongside Luminescence Laser and medical treatment.
Exosomes vs. PRP
Both aim to deliver growth factors to target tissue. PRP uses the patient's own blood-derived platelets; exosomes use cell-derived vesicles from allogenic sources. Exosome preparations do not depend on the patient's own blood, so they avoid PRP's person-to-person variation; however, commercial products are not yet standardised and head-to-head evidence is limited.
Safety
Dr Sin Yong uses only regulated, clinically validated exosome preparations from established manufacturers. Exosome therapy is still an emerging field without the long-term safety record of established treatments, which is why the source and regulatory status of the preparation matter.

Frequently Asked Questions
Exosomes are nano-sized vesicles carrying growth factors and proteins. Applied to skin, they are proposed to support skin regeneration and hair follicle activity; injection is not part of this practice.
The number and spacing of treatments are planned individually after assessment, depending on whether the aim is skin quality or hair, and on how the skin or scalp responds. Progress is reviewed before any further treatment.
Exosome preparations vary in source, from human cell-derived to plant-derived, and long-term safety data are still limited, so the choice of product matters. Dr Sin Yong uses clinically validated exosome products, including Derive Serum (exosome scalp topical) in his regenerative protocols.
Yes — exosomes are often used after laser or microneedling, where early studies suggest they may support post-treatment recovery and collagen remodelling.
No. Exosomes are tiny vesicles released by cells, including stem cells, but they contain no nucleus and no living cells, so they cannot divide or grow into tissue. They act as messengers, carrying growth factors and signalling molecules that influence how the receiving cells behave.
It depends on how the exosomes are delivered. Applied after a laser or microneedling, the recovery is essentially that of the laser or microneedling itself. Injection is not offered here; published reports of injected use describe short-lived redness, swelling or bruising at injection sites.
Early clinical studies report improvements in hair density and thickness, but most are small and use different products and protocols, so the evidence is promising rather than settled. Dr Sin Yong applies exosomes topically as one component of a hair loss plan, alongside laser and medical treatment, after the cause has been diagnosed.
Exosome treatment is usually deferred in pregnancy and breastfeeding, and it is not given over active skin infection or inflammation at the treatment site. Because the preparations carry growth factors, a history of cancer or a significant immune condition should be discussed with the doctor beforehand. Suitability is confirmed at consultation.
At this practice, applied, never injected. Exosome preparations are nanoscale cell-derived vesicles carrying growth factors and signalling molecules. In Singapore they are not approved for injection, so they are used topically, usually straight after RF microneedling or fractional laser while the skin barrier is open, or on the scalp within a hair loss plan. The evidence is early and mostly from small studies; exosomes support other treatments rather than replacing them. Details on exosome therapy.
No. Exosome products are not registered injectables in Singapore and are used topically, applied immediately after a fractional laser or RF microneedling session while the channels are open. Any clinic offering injected exosomes is outside the regulatory position described on this page.
Small split-face studies suggest shorter redness and recovery when a topical exosome product is applied straight after fractional resurfacing. That is the use here: recovery support as an adjunct, not a treatment on its own.
Not on the evidence available; the data are small case series of adjunct use. Hair loss is treated with medical therapy and, where follicles remain, Regenera Activa or H2LT; see hair loss and restoration.
