Complications management training, what it should actually contain

Last reviewed: 30 July 2026.

Who wrote this: Aurelia Institute trains healthcare professionals in medical aesthetics, so we have a commercial interest in this subject. We are not currently running courses and hold no awarding organisation approval. This page is a guide, not a course for sale, and it is not clinical advice. For management protocols, work from the published guidance named at the foot of this page and from your own clinical judgment.

There is no definition of complications training in UK aesthetics. No body sets its content, no examination confirms you can do it, and the phrase covers everything from an afternoon of being made genuinely uncomfortable to a slide deck and a certificate.

That matters more here than in any other part of this sector, because complications training is the only training where the thing you are learning has a clock attached. Vascular occlusion managed within minutes usually resolves. The same event managed within hours often does not.

This page sets out what serious complications training contains, what you need in place before you treat anyone, and where the published guidance actually lives.

The short version

Question	Answer
Is complications training required?	No law requires it. Insurers increasingly do, and some will not cover filler without it.
Is there a standard syllabus?	No. Content varies enormously between providers.
Where is the authoritative guidance?	The ACE Group and CMAC publish the guidelines UK practitioners work from.
What must I have on the premises?	Hyaluronidase, adrenaline, a written protocol, and the phone numbers below.
Is hyaluronidase prescription-only?	Yes. So the prescribing arrangement applies to your emergency drug too.
How often should I refresh?	Skills decay. Treat it as recurring rather than a one-off certificate.

Why this training is different

Most aesthetic training teaches you to produce a result. Complications training teaches you to recognise something going wrong and act before a window closes.

The recognition half is harder than people expect, because the early signs are not dramatic. Pain out of proportion to the procedure. Skin that looks pale, mottled or dusky. A patient who says the area feels tight or wrong. These are quiet signals, they appear while you are still holding a syringe and thinking about the next injection, and the natural response is to reassure rather than to stop.

Training that does not rehearse that moment has not prepared you for it.

What a serious course contains

Scenario work you have to speak through. A trainer describes a patient and you say aloud, in order, what you would do starting now. Not what the textbook says. What you would do, in your room, with the kit you actually own. Good trainers push back: if you say you would call for help, they ask who, and what happens on a Tuesday when that person is not in.

Recognition taught as pattern rather than as a list. Photographs and video of real events at the point they were still recoverable, not just the dramatic end stage that appears in lecture slides.

Anatomy revisited by risk rather than by region. Which vessels sit under which injection point, and why the glabella and nose carry a different order of consequence because of their connection to the retinal circulation.

The conversation. Telling a patient something has gone wrong is a skill people avoid practising, which is exactly why it belongs in the room. Patients told early, plainly and without defensiveness usually stay with you through treatment. Patients who sense they are being managed leave and complain.

Your own protocol, written on the day. The most useful thing you can leave with is a single page specific to your clinic, with your drugs, your locations and your numbers on it.

What you need before you inject anyone

This is the part that separates preparation from intention, and almost no course page lists it.

Item	Why
Hyaluronidase, multiple vials, in date, on site	The treatment for hyaluronic acid occlusion. Ordering it afterwards is not a plan.
Adrenaline, and knowing when to use it	Hyaluronidase itself can cause anaphylaxis.
A written emergency protocol, visible	You will not compose one while a patient is deteriorating.
Direct route to ophthalmology emergency services	Visual symptoms are a same-hour emergency.
Location of your nearest hyperbaric oxygen facility	Referenced in published guidance for severe cases. Find it now, not then.
A colleague you can ring	The single most useful item on this list.

Two of those catch people out.

Hyaluronidase is a prescription-only medicine. Everything true of botulinum toxin prescribing is true of it, which means a non-prescriber needs a route to obtaining it that does not depend on finding someone at seven on a Friday evening. Settle that with your prescriber in advance and write down what you agreed. Our guide to working with a prescriber covers the arrangement.

And whoever answers your phone needs briefing. A receptionist taking a message from a patient describing white skin or changed vision is a delay you cannot afford. That call goes through immediately, wherever you are. Write it down and put it by the phone.

Where the actual guidance lives

UK practitioners work from two sources, and knowing they exist puts you ahead of a fair number of people practising.

The Aesthetic Complications Expert Group, usually called the ACE Group, publishes guidance on managing adverse events including impending necrosis. Their material is the reference point most UK training and most insurers expect you to be working from.

The Complications in Medical Aesthetics Collaborative, CMAC, publishes peer-reviewed guidelines including work on the safe use of hyaluronidase and the management of hyaluronic acid filler-induced vascular occlusion. The modified high-dose pulsed approach that appears in current UK practice comes from this literature.

We are deliberately not reproducing dosing here. Protocols are revised, they depend on the presentation, and a paraphrase on a training provider’s website is the wrong place to learn them. Read the source, keep a current copy with your emergency kit, and check whether it has been updated when you renew your insurance.

Recognition, in the order it usually happens

Framed as what training should equip you to notice, rather than as a protocol.

During injection. Pain that is disproportionate. Blanching that does not refill. Resistance that feels different. The correct response is to stop, not to finish the syringe.

Minutes to hours. Persistent blanching, then a dusky or mottled pattern following a vascular territory rather than the shape of your injection. Increasing rather than settling pain.

Hours to days. Livedo pattern, blistering, and eventually necrosis if untreated. By this stage you are managing damage rather than preventing it.

Any visual symptom, at any point. Blurring, field loss, pain behind the eye, or a patient saying something is wrong with their sight. This is the emergency with the shortest window and the worst outcome, and it needs immediate escalation rather than observation.

The thing to internalise is that the treatable window is at the top of that list and the reason people miss it is that the top of the list is undramatic.

Delayed complications, which get less attention

Not everything happens on the day, and courses focused on occlusion sometimes skip the rest.

Delayed onset nodules can appear months after treatment, and distinguishing an inflammatory nodule from infection or biofilm changes what you do about it. Late-onset swelling has been associated with immune triggers including illness and vaccination. Granuloma formation is uncommon but real.

The practical implication is record keeping. A patient presenting eighteen months later with a nodule is a problem you can only solve if you know what product, which batch and which plane. That is the argument for recording batch numbers that people find tedious until the first time they need one.

Insurance, and why this is effectively compulsory

No UK law requires complications training. Insurers have made it close to mandatory anyway.

Most now ask whether you hold separate complications training, whether you keep hyaluronidase, and whether you have a documented protocol. Some will not write filler cover without it. If you are budgeting for training, treat complications as a required line rather than an optional extra, because the alternative is being trained and uninsurable.

Insurers also generally want notification of circumstances that might give rise to a claim, not only of actual claims. Ring them earlier than feels necessary. Late notification is a common reason cover gets disputed.

Refreshing

A drill you do once and never revisit decays quickly, and confidence decays more slowly than competence, which is the dangerous combination.

There is no mandated interval. What is worth doing is rehearsing the scenario aloud periodically with whoever you work with, keeping your protocol current, checking your hyaluronidase expiry on a schedule rather than when you need it, and booking a refresh when the last one stops feeling recent.

Ask any provider whether they give you the scenarios to take away and whether you can bring a real case back to them later. Providers who say yes are selling something more useful than a certificate.

What to check before booking

1. Will you run scenarios out loud, in front of someone who pushes back?
2. Is recognition taught from real cases at the recoverable stage?
3. Does the course cover delayed complications, or only acute occlusion?
4. Do you leave with a written protocol specific to your own setup?
5. Which published guidance does the course work from, and is it current?
6. Is there any post-course route to ask about a real patient?
7. Does your insurer accept this specific provider?

Where you can train

Complications training runs across the UK, and it is worth travelling for. This is the one course where a small group and a trainer willing to press you matters more than convenience.

Training and local information by city: London, Manchester, Birmingham, Leeds, Glasgow, Edinburgh, Bristol, Liverpool, Cardiff, Newcastle.

Frequently asked questions

Is complications training legally required in the UK?

No law requires it. Insurers increasingly do, and some will not provide dermal filler cover without evidence of it, which makes it effectively necessary for most practitioners.

What is vascular occlusion?

Filler entering or compressing a blood vessel so that blood supply to the tissue is interrupted. Untreated it leads to tissue death, and where the vessels connect to the retinal circulation it can affect vision.

What do I need on the premises before injecting filler?

Hyaluronidase in date and in sufficient quantity, adrenaline in case of anaphylaxis to the hyaluronidase, a written emergency protocol, a direct route to ophthalmology emergency services, and the location of your nearest hyperbaric oxygen facility.

Is hyaluronidase a prescription-only medicine?

Yes. A non-prescriber needs an arrangement that makes it available in an emergency rather than one that depends on reaching a prescriber at short notice.

Which guidance should I be working from?

The ACE Group publishes UK guidance on managing adverse events including impending necrosis. CMAC publishes peer-reviewed guidelines on hyaluronidase use and vascular occlusion management. Keep a current copy with your emergency kit.

How often should I refresh complications training?

No interval is mandated. Skills decay, so treat it as recurring, keep your protocol current, and rehearse scenarios with colleagues between formal courses.

Does a foundation course cover complications adequately?

It should introduce recognition and management, and that is not the same as making the response automatic. Separate complications training is the standard expectation and increasingly an insurance condition.

Does Aurelia Institute run complications courses?

Not at present, and we hold no awarding organisation approval. This page exists as a guide.
