How to check an injector is safe: a practical UK guide

This is the piece we would want a friend to read before booking anywhere, including with us.

The regulatory position in the UK is not what most people assume. While prescription-only medicines require a prescriber, a substantial amount of aesthetic practice — including some injectable work — can legally be performed by someone with minimal training. The industry has been moving towards tighter regulation for years, but the responsibility to check currently sits with you.

Check the register — it takes one minute

Ask for the practitioner's full name and professional registration. Then check it yourself on the relevant public register:

All are free, public and searchable by name. A legitimate practitioner expects this question and will not be offended by it. Hesitation or vagueness in answering is itself the answer.

The prescribing question

For botulinum toxin, the prescriber must consult with you personally before the medicine is prescribed. Remote prescribing — a prescriber signing off patients they have never assessed — is not acceptable practice and has been the subject of repeated regulatory warnings.

Fair question: "Who prescribes, and will I meet them?" If the prescriber is someone who never appears, that is a problem regardless of how good the injector is.

Insurance and complications

Ask two things:

1. "Are you insured specifically for this treatment?" — general clinic insurance does not necessarily cover every procedure.
2. "What is your complications pathway?" — a real answer names a person, a timeframe and a plan. For hyaluronic acid filler, it should include immediate access to hyaluronidase, the enzyme that dissolves it in an emergency.

Vascular occlusion — filler entering a blood vessel — is the emergency that matters. It is rare, it is time-critical, and the difference between a good outcome and tissue loss is whether the person treating you recognises it immediately and has the reversal agent to hand. Ask.

The warning signs

• Treatment on the day of first contact, with no prior consultation, for a prescription medicine.
• Pressure or urgency — a discount expiring today, a "last slot", a price only available if you book now.
• Treatment in a non-clinical setting — a home, a hotel room, a party. Sterility and emergency response both require an appropriate space.
• Refusal to name the product or show you the vial and batch.
• No medical history taken, or a form you sign without anyone reading it.
• Before-and-after photos that are not their own work, or that are obviously filtered.
• No mention of risk. Every treatment has some. A practitioner who does not discuss it is either inexperienced or not being straight with you.
• Prices well below the market. Product is a real cost. Substantially cheaper usually means diluted product, inexperienced hands, or both.

What good looks like

• A consultation that happens before, not during, treatment.
• A practitioner who says no to something — a dose, an area, a timeline.
• Named products, shown to you, opened in front of you.
• A written aftercare sheet and a way to reach someone that evening.
• A review appointment offered without you asking.
• Prices published in advance.

On before-and-after photographs

Useful, but read them carefully. Check the lighting is the same in both. Check the angle and the expression match. Check for makeup differences. Ask whether the photographs are the practitioner's own work and how long after treatment the "after" was taken.

A clinic showing consistent, unspectacular, well-lit results is usually more trustworthy than one showing dramatic transformations.

If something goes wrong

1. Contact the treating clinic first and immediately. Most complications are time-sensitive.
2. If you cannot reach them or are not taken seriously, seek independent medical help — A&E for anything acute such as sudden severe pain, blanching skin or visual disturbance.
3. Complications from a registered professional can be raised with their regulator.
4. Keep photographs, dates, and any product information you were given.

The single best test

Ask what they would refuse to do. A practitioner with a real answer — a dose they will not exceed, an area they will not treat, a patient they would turn away — has standards. One who says they can do whatever you would like has told you something important.
