What is an exosome injection, and does it work?
An exosome is a very small packet released by a cell. The International Society for Extracellular Vesicles defines the wider group, extracellular vesicles, as particles released from cells, wrapped in a fat-based membrane, that cannot replicate on their own. The Society also recommends the plain term "extracellular vesicle", because "exosome" is used inconsistently and can mislead. A product sold under the word is therefore not one standard thing, and what is in a vial depends on its source and how it was made.
Researchers are studying these particles in many fields, and that work is early. Research interest is not the same as an established treatment. The clinic's own position, and what it does and does not offer, is set out on the page about why we do not offer exosomes.
What have regulators said about exosome products?
The US FDA has said that there are currently no FDA-approved exosome products. In December 2019 it reported multiple cases of serious adverse events in patients in Nebraska who had been treated with unapproved products marketed as containing exosomes. It also says exosomes used to treat diseases in humans are regulated as drugs and biological products that need approval before sale. Its 2020 consumer alert adds a list of conditions for which no such product has been approved, and the list includes macular degeneration and blindness.
For Malaysia, no statement specific to exosome injections from the National Pharmaceutical Regulatory Agency (NPRA) or the Ministry of Health was found while preparing this article. What does exist is the NPRA's guideline for cell and gene therapy products (second edition, September 2025). It lists extracellular vesicles among the products outside that framework, and says products for cosmetic or anti-aging purposes in that framework are not allowed unless they have a medicinal purpose backed by clinical studies. It does not say that exosome injections are approved, and it does not say that they are prohibited. Whether a particular product is registered is therefore a question to put to whoever is selling it, and the answer is a registration number that can be searched, as the last section explains.
A search of the registers on 13 October 2026 makes the point concrete. The NPRA product search (QUEST3+) found no registered medicine with "exosome" in its name, and the Medical Device Authority register found no registered device. The same NPRA search found 226 notified cosmetics with "exosome" in the name: creams, serums and similar products. A cosmetic is made to be applied to the outside of the body, so a cosmetic is not a product to inject.
Can an injection under the eye reach and repair the retina?
The retina is a thin, light-sensitive layer lining the back inside the eye, as the US National Eye Institute describes it. An injection under the eye goes into the skin and the tissue beneath it, outside the eyeball. The sources checked for this article show no evidence that an injection there treats retinal disease. The FDA lists macular degeneration and blindness among the conditions for which no exosome product has been approved.
A claim that an injection will travel to another organ and repair it is a claim that needs evidence, and it is fair to ask for that evidence in writing. Blurred vision has many causes, and an eye specialist can examine the retina directly. Any change in vision is a reason to see an eye specialist, and a sudden change is a reason to go to an emergency department.
Who may inject you in Malaysia?
The Ministry of Health's guideline on aesthetic medical practice says aesthetic medical procedures are performed by a registered medical practitioner who holds a Letter of Credentialing and Privileging (LCP), as set out in who can perform aesthetic procedures in Malaysia. In a written parliamentary reply reported in November 2024, the Health Minister said invasive aesthetic procedures may be done only at facilities registered under the Private Healthcare Facilities and Services Act 1998, and only by registered doctors with an LCP.
A doctor who is registered in another country is not automatically allowed to practise here. The Malaysian Medical Council says practitioners must register with it to practise medicine in Malaysia. Under section 16 of the Medical Act 1971 it can issue a temporary practising certificate to a foreign registered practitioner, for not more than three months, for teaching, research, post-graduate courses, fellowship training or clinical attachment. The application is made by a fully registered local practitioner who supervises, at an address listed on that practitioner's practising certificate. A patient can ask to see the certificate and the arrangement.
When the name on the door and the activity do not match
A premises can call itself a clinic, a centre or a wellness space. The law looks at what is done there. The Ministry of Health received 352 complaints about complications of aesthetic procedures at unregistered premises between 2023 and September 2024, and the Minister said the Ministry has never allowed aesthetic procedures at beauty centres. The regulation guide above makes the practical point: the useful question is who will hold the needle, and whether that person is the registered doctor who assessed you, whatever the place calls itself.
Most people who ask these questions are doing the right thing. Asking is the check.
Three checks before anyone injects you
- The premises. Ask to see the registration certificate under the Private Healthcare Facilities and Services Act 1998 and check that it is for this address.
- The person. Search the doctor on the Malaysian Medical Council register for full registration and a current practising certificate, then find the same name on the Ministry of Health aesthetic registry and read which procedures the LCP lists. Ask who will do the injection. For a visiting doctor, ask to see the temporary practising certificate. How to check an aesthetic doctor in Malaysia goes through each register.
- The product. Ask for the name, the maker and the registration number, and search the number on the matching register. An injectable medicine carries a MAL number, and a device is listed on the Medical Device Authority register. A number on a register does not show that the box in your hand is genuine, so read the entry against the box. How to check if a product is KKM approved explains which register applies. A product with no number, or a number that returns nothing, is unverified.
If any one of the three cannot be answered, that is a reason to pause, whatever the treatment is called. Ask what the plan would be without the injection, and what the evidence says for your particular concern.
If you have already had an injection like this
Keep the product name, any batch details, the date, the place and the name of the person who did it, along with receipts and dated photographs. Contact the person who treated you and say what has changed. Pain, swelling or redness that is spreading, or any change in vision, needs a doctor's assessment the same day, and a sudden change in vision needs an emergency department. If the problem concerns your eyesight, an eye specialist should examine the eye.
The article on what to do when something goes wrong after an aesthetic treatment sets out the urgent signs, what to keep and which body handles which complaint. This article is general information and is not medical or legal advice.
