If you read only one page on this site, read this one. Nearly every serious misunderstanding patients have about aesthetic treatment traces back to a single missing distinction: the difference between a medicine and a device, and what each one requires by law.
Two legal categories, two entirely different regimes
Medicines are regulated under the Human Medicines Regulations 2012. Some are available only on prescription. A prescription only medicine may be sold or supplied only in accordance with a prescription given by an appropriate practitioner, and an appropriate practitioner means a doctor, a dentist, or a registered professional holding prescribing rights, such as a nurse independent prescriber or a pharmacist independent prescriber.
Medical devices are regulated under a separate regime overseen by the Medicines and Healthcare products Regulatory Agency. Devices are placed on the market under conformity assessment procedures. There is no prescription concept, and the device regime governs the product rather than who may use it on you.
Botulinum toxin products fall in the first category. Most dermal fillers fall in the second. That single fact produces almost all of the asymmetry patients notice but cannot explain.
| Product type | Regulated as | Prescription required | Registration required to administer |
|---|---|---|---|
| Botulinum toxin products | Prescription only medicine | Yes, for a named patient after assessment | Administration may be on the direction of the prescriber |
| Most dermal fillers | Medical device | No | In most of the UK, none is legally required for an adult |
| Prescription strength topical medicines | Medicine, often prescription only | Yes where prescription only | Supply follows the prescription |
| Laser and light equipment | Device, in respect of the equipment | No | Varies by local authority licensing |
| Injectable products marketed for hydration | Varies by product | Ask which category the specific product falls in | Depends on the category |
Categories depend on the specific product. Ask for the product name and check it rather than reasoning from the treatment name.
What follows for botulinum toxin
Because these products are prescription only medicines, a lawful treatment requires that an appropriate practitioner has assessed you and prescribed for you. It is not enough for a clinic to have a doctor or prescriber somewhere in its structure. The prescription is for a named patient, following an assessment of that patient.
The person who then administers the injection need not be a prescriber. A medicine can be administered by another person acting on the direction of the prescriber. That is ordinary and lawful and happens throughout healthcare. What is not acceptable, and what the professional regulators have addressed directly, is prescribing for someone the prescriber has not assessed. See remote prescribing and why it matters.
So there are two questions rather than one, and most patients ask neither. Who is the prescriber, and when did or will that person assess me.
- Open
- The professional register of whoever is named as your prescriber
gmc-uk.org | nmc.org.uk | pharmacyregulation.org | olr.gdc-uk.org - Type in
- The prescriber's full name and registration number, which you should ask for in writing before the appointment. Then check the entry for a prescribing annotation where the profession requires one.
- A good result looks like
- A current registration, a licence to practise for a doctor or a prescriber annotation for a nurse or pharmacist, and a clinic that tells you plainly when that person will assess you in person.
- An ambiguous result looks like
- A clinic that names no prescriber. A prescriber who will assess you only by video or by form. A prescriber named who turns out not to hold a prescribing annotation. A statement that the prescriber has already prescribed for you before meeting you.
- What it does not prove
- That a prescription was properly written for you. Registration establishes who may prescribe. Only an assessment of you establishes that a prescription for you was properly made.
- Note
- If the treatment is a filler rather than a medicine, there will be no prescriber and that is not a failing. Ask the device questions instead.
What follows for dermal fillers
Because most dermal fillers are devices rather than medicines, there is no prescription, and therefore no prescriber, and therefore none of the protection that a prescribing regime brings. In most of the United Kingdom there is at present no legal requirement that a person injecting a dermal filler into an adult holds any professional registration whatsoever.
This surprises people, and it should be stated without drama and without softening. It is the current law rather than a scandal somebody is concealing, and it is precisely why the licensing power discussed in the England licensing article was legislated for.
The practical consequence for you is that for fillers, every protection you get is one you asked for. Nobody is required to have assessed the injector, the premises or the product on your behalf. This is developed in why fillers are not prescription only.
Other treatments, sorted by the same test
Apply the same question to anything you are offered. Is this a medicine or a device, and if it is a medicine, is it prescription only.
- Prescription strength topical products, including certain retinoids and other agents, are medicines and where they are prescription only they require a prescription following assessment.
- Injectable products marketed for skin hydration or regeneration vary. Some are devices. Some are medicines. Ask which, and ask for the product name so you can check.
- Local anaesthetics may be prescription only or may be available in other classifications depending on the specific product and strength, so the same question applies.
- Energy based treatments such as laser and radiofrequency involve no medicine at all in themselves, so no prescriber is required. Their regulation, where it exists, runs through device rules for the equipment and local authority licensing in some areas.
- Prescription only medicines used off label remain prescription only, and the prescriber remains responsible for the decision.
You do not need to memorise categories. You need one sentence, asked in writing: is the product you propose to use a prescription only medicine, a device, or something else, and what is it called.
Where the medicine came from
There is a further link in the chain that patients rarely ask about and are entitled to. Prescription only medicines reach a clinic through a regulated supply chain. Products obtained outside it are a real problem, and the MHRA has an interest in it.
The question to ask is simple and not aggressive: which named product will be used, and can I see the packaging or the batch number recorded in my notes. A clinic operating properly will not find this odd, because recording product and batch is ordinary practice. This connects to how to check a claim about a product.
Why you will not see toxin advertised by brand
One consequence of prescription only status catches people out. Prescription only medicines may not be advertised to the general public. That is why responsible providers do not advertise botulinum toxin by brand name to the public, and why seeing a brand name used prominently in consumer advertising is a matter you can report. The mechanics of that, and how to report it, are in what an advertising rule breach looks like.
The corollary is useful in the other direction too. A provider who carefully avoids brand names in public material and explains why is demonstrating that they understand the regime they operate in.
- Ask, in writing: is the product a prescription only medicine or a medical device, and what is it called.
- If a medicine, ask for the prescriber's name, registration number and the date they will assess you.
- Check that registration yourself, including any prescribing annotation.
- If a device, ask who will inject, what registration they hold, and what indemnity covers the procedure.
- Ask for the product name and batch number to be recorded in your notes on the day.
The two questions, condensed
For anything injectable, ask two questions in writing and keep the answers.
Is this product a prescription only medicine or a device. If a medicine, who is the prescriber, what is their registration number, and when will they personally assess me. If a device, who is injecting it, what registration do they hold if any, and what indemnity covers it.
Two questions. Everything else on this site is detail hanging off them.
