What exosomes are
Exosomes are nano-sized extracellular vesicles, about 30 to 150 nm across. Cells release them as messengers. They carry growth factors, lipids and nucleic acids. They are signalling cargo and are not living cells.
Products may come from human or animal stem-cell culture, or from plant tissue. They vary in source, concentration and stability, so the word exosome does not describe one single product. It is reasonable to ask for the exact product to be named before you agree to anything. This guide is general information, not a personal recommendation.
How exosomes are used here
Exosomes are applied as an adjunct, typically right after a procedure such as RF microneedling, fractional CO2 or pico fractional laser. On scalp plans, they are used within a hair loss protocol. The procedure does the main work. The exosome product is an added layer, and it may be dropped from your plan if it does not help. Products vary, so your quote names the one used. Hair loss needing a diagnosis is assessed before any scalp adjunct.
Exosome treatment Singapore: topical or injected?
| Route | Status here | Why it matters |
|---|---|---|
| Topical after a procedure | Used | The procedure opens a route through the skin |
| Topical on intact skin | Limited value | Large vesicles mostly stay on the surface |
| Injected | Not part of practice here | Injectable use is a different regulatory category, and no injectable exosome product is approved by the Health Sciences Authority |
| Over-the-counter serum on intact skin | Limited value | The same surface barrier applies |
What the evidence says
Human evidence is early. Studies are small, and the products tested differ from one another. Reported benefits relate to the period after a procedure. In small studies, the effect of the adjunct cannot be reliably separated from the effect of the procedure itself. That is a real limit, and it is why exosomes are not presented as a treatment in their own right. A scar or skin result comes from the procedure.
Exosomes for skin and for hair
May be used after fractional laser or RF microneedling to support the recovery period.
Some plans are staged over several visits, depending on the underlying programme.
Scar change comes from the procedure, as our 4D Scar Reconstruction page explains.
Topical scalp exosomes are an adjunct within a hair protocol. They are not a stand-alone cure for pattern hair loss.
This goes to a proper hair protocol or a dermatologist first.
How an exosome step works
Who it may suit
An exosome step may suit you if you are already having fractional laser or RF microneedling. You should accept that evidence is early, want the product named and discussed openly, and have realistic expectations of an adjunct. If you are looking for an injection, a stand-alone effect or a cure for hair loss, this is not a good fit. The consultation decides whether the step is worth adding to your plan.
Who should wait or avoid it
Active infection, inflammation or an open wound in the area.
An active cold sore in the area.
A known allergy to a product component.
Safety data are limited.
Anything that rules out the laser or microneedling also rules out this step.
What it cannot do
It does not take the place of a well-chosen treatment.
It is not an injectable or a stand-alone treatment here.
It cannot cure androgenetic hair loss.
On intact skin, large vesicles mostly stay on the surface.
Risks, sessions and aftercare
Redness, warmth and mild irritation can occur, mainly from the paired procedure. Less common problems are contact or allergic reaction, a flare of an existing condition, or infection. Session numbers depend on your underlying plan. Recovery support may be a single session, while skin-quality programmes are staged, so numbers cannot be given before assessment. No duration of effect can be promised. Progress is reviewed against baseline photographs. Afterwards, follow your procedure aftercare, and avoid touching the area. Avoid make-up and saunas at first, use only the gentle products provided, and avoid scrubs, acids and retinoids until reviewed. Use sunscreen. Contact the clinic the same day for worsening redness, swelling or itching, pus, crusting or fever, worsening pain, a rash or hives. Our complication care page explains what happens next.
How fees are worked out
Fees are not published. They depend on the delivery procedure, the area treated, the exosome product, and whether it forms part of a hair or scalp plan. A written quote with the product named is given after consultation. The consultation also decides whether an adjunct is advised at all.
