This is the fact that most reliably surprises people, and it is stated here without hedging because hedging it would be a disservice. It is also the fact that explains why the rest of this site is written the way it is.
The legal position, plainly
Dermal fillers, in the great majority of cases, are regulated as medical devices. The device regime governs how a product is placed on the market. It does not create a prescription, and it does not restrict who may use the product on a patient.
Because there is no prescription, there is no prescriber, and none of the assessment structure described in the prescribing article applies. Because there is no restriction on who may administer, there is at present no general legal requirement in most of the United Kingdom that the person injecting a filler into an adult holds any professional registration at all.
Two important qualifications. First, the position for under 18s in England is different, because the Botulinum Toxin and Cosmetic Fillers (Children) Act 2021 created offences relating to administering fillers to under 18s for cosmetic purposes and to making arrangements for it. That is covered in the under 18s article. Second, a small number of injectable products marketed alongside fillers may be medicines rather than devices, so the category has to be checked product by product rather than assumed.
What follows for you
The consequence is not that filler treatment is unsafe or that practitioners are unqualified. Many are highly qualified statutory registrants with years of experience. The consequence is structural: nothing in the law guarantees it, so you have to establish it.
In a toxin treatment, medicines law forces a chain of accountability into existence whether or not you ask about it. In a filler treatment, no such chain is required. The questions you ask are the only thing creating one.
- Open
- The professional register the injector names, if they name one
gmc-uk.org | nmc.org.uk | olr.gdc-uk.org | hcpc-uk.org | pharmacyregulation.org - Type in
- The injector's full name and registration number. If they tell you they hold no statutory registration, that is a lawful answer for an adult filler treatment in most of the UK, and it is information you are entitled to before deciding.
- A good result looks like
- A current registration on a statutory register, matching the name of the person who will actually inject you, together with a clear answer about indemnity cover for the specific procedure.
- An ambiguous result looks like
- A registration in the name of a colleague rather than the injector. A claim of registration with a body that turns out to be a private training company. A refusal to answer the question.
- What it does not prove
- That the person is trained in filler injecting, because no statutory register records that. It proves professional registration and nothing about aesthetics.
- Note
- For fillers, an absent registration is not unlawful. It is a fact you should have before you consent, not after.
The filler specific questions
Because the standard prescribing questions do not apply, substitute these. Ask in writing.
- What exactly is the product, by full name, and is it a device or a medicine.
- Who will inject it, and do they hold any statutory professional registration, with the number.
- What indemnity insurance covers this specific procedure, and who is the provider.
- Is this product reversible, and if not, what are the options if I am unhappy with the result.
- If a complication needs hyaluronidase, who can prescribe and administer it, and how quickly, including out of hours.
The last of these is worth expanding. Hyaluronidase is an enzyme used to dissolve hyaluronic acid fillers, and it is a prescription only medicine. That produces a situation patients rarely anticipate: the product used to manage a complication from an unregulated device may itself require a prescriber. Asking who can obtain and administer it, and how quickly, is a serious question rather than an obscure one, and the answer tells you a great deal about how the service is set up.
| Protection | Botulinum toxin | Most dermal fillers |
|---|---|---|
| Prescription required | Yes | No |
| Assessment required by medicines law | Yes, by the prescriber | No |
| Named accountable prescriber exists | Yes | No |
| Registration required to administer | Administration on the prescriber's direction | None generally required for adults in most of the UK |
| Public advertising of the product permitted | No, it is a prescription only medicine | Yes, subject to the advertising codes |
| Reversal agent | Effect wears off over time | Hyaluronidase for hyaluronic acid products, which is prescription only |
A framework written by this publication to organise the procedure. It is not a measurement, a guideline or a regulator's classification.
Establishing what is being injected
Because the device regime governs products, product identity matters and is checkable in a way that vague descriptions are not.
Ask for the product name in full, and ask that the name and batch number are recorded in your notes on the day. A clinic that will not tell you what it proposes to inject into your face has told you something. A clinic that records product and batch as a matter of routine is operating the way a clinic should. How to look into a product claim is set out in how to check a claim about a product or device.
Also worth knowing: the MHRA operates the Yellow Card scheme, which receives reports about medicines and also about medical devices, including adverse incidents. If something goes wrong with a device, that reporting route exists and you can use it yourself.
Permanent and semi permanent products
Fillers differ enormously in what they are made of and how long they persist. Hyaluronic acid fillers can generally be dissolved with hyaluronidase. Products of other compositions may not be reversible in the same way, and some are designed to be long lasting or permanent.
This is a question to ask before treatment rather than after, and the wording is simple: is this product reversible, and if I do not like the result or something goes wrong, what specifically can be done. A clear answer, whatever it is, lets you make a decision. A reassuring non answer does not.
Why the law here may change
The gap described in this article is precisely the gap that the licensing power in section 180 of the Health and Care Act 2022 was legislated to allow the government to address in England. Whether regulations have been made and commenced is a question to check at source, and the method for checking it is in the licensing article.
Until a scheme is in force, the position described here is the position. Anyone telling you that fillers are already licensed and regulated in the way medicines are is either mistaken or selling something. The verification is two minutes on legislation.gov.uk and you can do it yourself.
This is not an argument against fillers
It is an argument for asymmetric care. For a toxin treatment, the law has built you a chain of accountability, and your job is to check it exists. For a filler treatment, the law has built you very little, and your job is to build it yourself out of written questions, register checks, indemnity evidence and a clear plan for complications.
People make that effort routinely for far smaller purchases. It is entirely reasonable to make it here.
