What to do when an aesthetic treatment doesn’t go as planned — from a GP who handles corrective work

By Dr Amber Halliday, MRCGP MBBS BSc (Hons), GP & Aesthetics Doctor · Blue Bird Aesthetics, Worthing · Updated 2026

Aesthetic treatments are more popular than ever, and most of them go well. Patients leave clinic happier than they arrived, results settle as expected, and life carries on. But not every treatment goes as planned. Sometimes the result does not match the expectation. Sometimes there is a complication. Sometimes a patient is left worried, unsure who to turn to, or wondering whether what they are experiencing is normal.

This guide is for those patients. It is a practical, clinically grounded resource for anyone who has had an aesthetic treatment that has not met expectations, anyone researching their options before booking a new treatment, and anyone trying to work out whether what they are experiencing right now needs medical attention. It is not an advert. It is the conversation I have most often in clinic, written down.

As an NHS GP as well as an aesthetics doctor, corrective consultations are a regular part of my work. I see patients who have had treatment elsewhere and come to me for an honest assessment of what has happened, what can be done about it, and whether anything should be done at all. The right answer is sometimes treatment. The right answer is sometimes time. And occasionally, the right answer is referral to a specialist colleague. The honesty matters more than the outcome.

“Most aesthetic treatments go well. When they don’t, knowing where to turn matters enormously. The first instinct should not be panic, and it should not be silence — it should be an honest conversation with a medically qualified clinician who can tell you what you are actually looking at.”

— Dr Amber Halliday, MRCGP MBBS BSc (Hons)

Who This Guide Is For

This guide is for you if you have had an aesthetic treatment that did not turn out as expected, or if something has developed in the weeks or months since. It is also for you if you are researching what to look for, or planning your next treatment and want to choose a safer clinic this time. And it is for anyone who simply wants to understand what aesthetic complications actually look like — rather than the alarmist version on social media.

If you have visual changes, sudden severe pain, or white or purple discolouration of the skin following a recent filler treatment — stop reading. This is a medical emergency. Contact your treating practitioner immediately, and if you cannot reach them, go straight to A&E. Vision-threatening complications from filler are rare but time-critical. The rest of this guide is for non-emergency concerns.

TL;DR — Key Takeaways

Short on time? Here’s the summary:

✓ Complications can occur even with skilled, well-intentioned practitioners. The risk profile depends heavily on the treatment, the practitioner, and the regulatory framework around their work.

✓ A medically qualified clinician — a GP, doctor, or appropriately qualified prescriber — is the right person to assess and manage most aesthetic complications.

✓ Hyaluronidase can dissolve hyaluronic acid (HA) filler in most cases, but not all complications are reversible and it does not work on non-HA fillers such as Sculptra or Radiesse.

✓ Vascular occlusion, where filler enters a blood vessel, is rare but a true medical emergency — visual symptoms, severe pain, or white or purple skin need immediate care.

✓ Anti-wrinkle injection complications (heavy brow, asymmetry, frozen look) are unsettling but typically temporary, resolving as the product wears off in three to four months.

✓ Before any aesthetic treatment, check Save Face, the GMC or NMC register, and whether the practitioner is a prescriber. These checks take five minutes and matter.

✓ Dr Amber Halliday offers calm, considered, commitment-free corrective consultations at Blue Bird Aesthetics, Worthing. No hard sell — honest assessment, evidence-based options.

1. When Aesthetic Treatments Don’t Go to Plan

Aesthetic medicine is a clinical discipline, but it is also a deeply personal one. Two patients with the same anatomy and the same treatment can experience completely different reactions to the result. ‘Going wrong’ in aesthetics covers a much wider spectrum than most patients realise — from frank medical complications at one end, through technical execution issues, all the way to results that are clinically fine but emotionally unsatisfying.

It is worth naming this honestly because the appropriate response is different in each case. A genuine medical complication needs urgent clinical management. A poor technical result needs assessment and considered correction. An emotionally unsatisfying outcome needs a calm conversation about expectations, and sometimes about what the next step should not be. I have all three conversations regularly.

There is also a category that is rarely discussed: results that are not wrong, but are not optimal. Filler that has integrated reasonably well but creates a slightly heavier look than intended. Anti-wrinkle injections that have softened too much rather than too little. These are not complications in the medical sense — but they are still legitimate reasons to seek an assessment, and they are usually correctable.

2. What Can Go Wrong with Dermal Fillers

Dermal fillers are generally safe in skilled hands, but they are medical injections of foreign material into the face, and a range of issues can occur. The risk profile varies significantly by injection site (the lips and tear troughs carry different risks from the cheeks) and, even more importantly, by practitioner qualification.

Overfilling and unnatural results

By far the most common reason patients come to me for corrective consultation. Overfilling can happen gradually — a small addition each year that, after several treatments, has taken the face somewhere it was never meant to go. It can also happen in a single treatment where too much product was placed in too little tissue.

Asymmetry

A degree of underlying facial asymmetry is normal and present in everyone. The aim of good filler treatment is to work with it, not against it. Asymmetry that follows treatment is sometimes a technical issue, sometimes a result of differential settling, and sometimes a reflection of asymmetry that was always there but is now more visible.

Lumps, nodules, or product migration

Lumps can appear immediately after treatment (often resolving with massage and time) or months later (typically needing assessment). Migration is the slow drift of product away from where it was placed and is particularly common in the lips and the tear trough region. Both have specific clinical approaches.

Tyndall effect

A bluish or greyish discolouration that occurs when filler is placed too superficially, particularly under the eyes. It is caused by light scattering off the gel and is essentially impossible to massage or wait out — it usually requires hyaluronidase to resolve.

Vascular occlusion

Rare but serious. Vascular occlusion occurs when filler inadvertently enters or compresses a blood vessel, restricting blood supply to the tissue or, in the worst cases, the eye. It requires urgent recognition and treatment with hyaluronidase — which is why having a medical professional involved from the outset matters enormously.

Warning signs of a vascular occlusion

Sudden severe pain during or after injection, skin that turns white or develops a mottled purplish pattern, or any change in vision following filler. These are emergencies. Contact your treating practitioner immediately; if unreachable, go straight to A&E. Tell them this is a possible filler-related arterial occlusion — it changes how it is managed.

Delayed inflammatory reactions are another category worth mentioning briefly — lumps or nodules appearing weeks or months after filler, sometimes triggered by illness, vaccination, or dental work. These need clinical assessment because the management differs from straightforward dissolving.

3. What Can Go Wrong with Anti-Wrinkle Injections

Anti-wrinkle injections — botulinum toxin treatments, the most common of which is Botox — have a different and generally lower risk profile than fillers. The complications that do occur are almost always temporary, because the product wears off naturally over three to four months. This is an important reassurance: even when something has not gone right with anti-wrinkle injections, time is on your side.

Brow ptosis (heavy or dropped brow)

A heavy or asymmetrically dropped brow following treatment, usually because product has affected nearby forehead muscles more than intended. It is unsettling but resolves entirely as the product wears off. In the meantime there are minor strategies (positioning, timing of further treatment) that can help.

Eyelid ptosis

True eyelid drop is rarer but more noticeable, caused by product diffusion to the muscle that lifts the upper eyelid. Like brow ptosis, it resolves with time. Certain eye drops can sometimes provide partial improvement during the recovery period.

Asymmetry

Slight asymmetry in result is common and often correctable with a small top-up at the two-week review (when results have fully settled). More marked asymmetry needs assessment to work out whether to add product, leave it to settle further, or wait it out.

Over-treatment and frozen appearance

Where too much product, or product in too many areas at once, has produced a result that lacks natural expression. This is more often a stylistic issue than a technical one. The correction is patience — the effect softens as the product wears off — and a different conversation about goals before the next treatment.

Unintended spread

Diffusion of product to muscles other than the targeted ones, producing effects such as a heavy upper lip after smile-line treatment, or temporary swallowing or chewing changes. These are uncommon, but worth knowing about and discussing with your practitioner before any treatment near the lower face.

An important reassurance about anti-wrinkle complications

Unlike filler complications, anti-wrinkle complications resolve completely as the product wears off — typically over three to four months. They are temporary, even when they are unpleasant. This does not mean they should be dismissed or ignored — but it does mean that the conversation, when something is not right, is mostly about managing the time until normal function returns.

4. Why Practitioner Qualifications Matter Most When Things Go Wrong

This is the section I would most like every prospective aesthetics patient to read. The single biggest predictor of how a complication is managed — and therefore how it resolves — is the qualifications of the practitioner who is dealing with it.

Who can actually prescribe hyaluronidase?

Hyaluronidase, the medicine used to dissolve hyaluronic acid filler and the first-line treatment for vascular occlusion, is a Prescription-Only Medicine. It must be prescribed by a registered medical prescriber: a doctor, dentist, independent nurse prescriber, independent pharmacist prescriber, or independent paramedic prescriber. A practitioner who is not a prescriber cannot legally hold or prescribe it. They must work alongside a prescribing partner — and that partner may not always be immediately available when a complication occurs.

Clinical training to distinguish normal from abnormal

Not every lump is a complication. Not every red patch is an infection. Distinguishing between normal post-treatment changes and an early complication is genuinely difficult and depends on years of clinical training. A GP or doctor brings the broader medical experience that helps make these calls confidently. This is not a comment on individual practitioners outside medicine — it is a comment on the depth of clinical training underneath the aesthetic qualification.

Emergency management capability

Vascular occlusion is the canonical example, but anaphylaxis to hyaluronidase or to local anaesthetic is also a possibility. The capacity to recognise and respond to a true medical emergency — with the right drugs immediately to hand and the clinical experience to use them — is what separates a safely run aesthetic clinic from a cosmetic one.

5. Hyaluronidase — Dissolving Filler

Hyaluronidase is an enzyme that breaks down hyaluronic acid (HA) filler. It is the most important corrective tool in aesthetic medicine, and it has two distinct roles: the everyday correction of cosmetic concerns, and the emergency management of vascular occlusion. Both are real, and both deserve to be done by a properly qualified clinician.

Hyaluronidase works quickly. Most visible change appears within 24 to 48 hours, with further settling over the following week. It can be used for overcorrection, poor cosmetic result, migration, Tyndall effect, and — in emergencies — vascular occlusion. It carries real risks of its own, most importantly a small but documented risk of anaphylaxis, which is why any clinic offering it must have adrenaline and emergency equipment on site.

Crucially, hyaluronidase only dissolves hyaluronic acid filler. It does not work on Sculptra (poly-L-lactic acid), Radiesse (calcium hydroxylapatite), or silicone. If you do not know what filler was placed in you, the first step is to find out. Your treating practitioner should be able to tell you immediately, and a reputable clinic will have it documented.

Before hyaluronidase treatment, a medical consultation is essential

Not every concern needs dissolving. A proper assessment will determine whether dissolving is the right step now, whether the area would benefit from time and conservative management, whether a lump might have a different cause (such as infection), and whether emergency equipment and escalation pathways are in place. If a clinic offers to dissolve filler without this assessment, find another clinic.

A dedicated guide to hyaluronidase — covering exactly how it works, what to expect from the procedure, and how to choose a safe clinician for dissolving — is available separately on the Blue Bird Aesthetics journal. The link is in the further reading section at the end of this guide.

6. What to Do If You’re Concerned Right Now

If you are reading this because something has just happened, this section is for you. The right next step depends entirely on what you are experiencing.

Suspected vascular complication — medical emergency

White, purple, or mottled discolouration of the skin, severe pain that does not match normal post-treatment soreness, or any change in vision following a filler treatment: contact your treating practitioner immediately. If you cannot reach them within minutes, go straight to A&E. Tell them this may be a filler-related arterial occlusion. Do not wait. Do not try to manage this at home.

For non-emergency concerns — lumps, asymmetry, disappointing results, or anything that feels off but is not painful or rapidly changing — the right first step is to contact the practitioner who treated you. Most reputable clinics will see you for a review, and many issues can be resolved with their input.

If you cannot reach your treating practitioner, if their response feels dismissive, or if you simply want a second opinion, seek assessment from a medically qualified independent practitioner. A doctor-led consultation is the right starting point. Bring any records you have of the treatment — product name, batch number if available, dates — and clear photographs of how the area looked at the time of treatment and how it looks now.

Practical things to do (or not do) while you wait

Do not apply pressure, heat, or aggressive massage to the area without specific guidance from a clinician — some of these can make migration worse, not better. Do take photographs of the concern, dated, in good light. Do write down a timeline of what has happened, when, and any associated symptoms. This documentation is genuinely useful at consultation.

7. How to Find a Safe Practitioner (Before Your Next Treatment)

If you are reading this guide because you are choosing a clinic for your first or next treatment — not because of a complication — this is the most useful section for you. The checks below are not exhaustive, but they are the ones that matter most.

Check the Save Face register at saveface.co.uk. Save Face is a government-recognised, verifiable register of qualified practitioners. Listed practitioners have had their qualifications, premises, insurance, and prescribing arrangements independently checked. It is not a perfect filter, but a practitioner not listed there should prompt further questions.

Check GMC registration for doctors at gmc-uk.org, NMC registration for nurses at nmc.org.uk, GDC for dentists, and GPhC for pharmacists. These take seconds and will confirm whether your practitioner is currently registered with no restrictions. Any practitioner worth booking will be happy for you to do this.

Ask whether the practitioner is an independent prescriber, and whether they personally hold and can prescribe hyaluronidase. If they are not a prescriber, ask about the prescribing arrangement — who prescribes, where they are based, how quickly they can be reached in an emergency. The honest answer to that last question is critical.

Look for ACE Group membership. The Aesthetic Complications Expert Group is a UK organisation focused specifically on complication management. Membership demonstrates active engagement with the seriousness of the medicine end of aesthetics.

Be cautious about very low prices, the absence of a real consultation process, same-day pressure to proceed, or practitioners who cannot explain their qualifications confidently. The phrase ‘it’s usually fine’ is not a clinical reassurance. None of this is about price-shaming or snobbery — it is about whether the cost of the treatment can reasonably include the cost of being equipped to manage a complication.

For a more detailed framework on choosing an aesthetics clinic safely — including a self-assessment quiz — I have written a separate, longer guide on the Blue Bird journal. The link is in the further reading section.

8. How I Approach Corrective Treatment at Blue Bird Aesthetics

Corrective consultations are a meaningful part of my work, and I take them seriously. Patients who come to me about a previous treatment that has not gone well are often anxious, sometimes upset, and almost always have spent time worrying before they got as far as making the appointment. The first thing the consultation needs to be is calm.

As a GP and an aesthetics doctor, I can assess, prescribe, and manage the most common aesthetic complications myself. Hyaluronidase is available at the clinic following consultation, and is administered by me personally with full emergency equipment on site. For complications outside my scope — a complex vascular event in the days following treatment, for example, or a suspected biofilm infection — I will refer to specialist colleagues without hesitation. Referral is a clinical decision, not a failure.

What I will always do is give you an honest assessment of what is and is not achievable. I will not dissolve filler that is integrated and not causing a problem just because you have come in asking. I will not promise a single visit will resolve something that needs staged treatment. And I will tell you, openly, when the right answer is to wait, or to seek a second opinion, or to do nothing at all. The right answer is sometimes no treatment — and that conversation matters.

Frequently Asked Questions

Can filler always be dissolved?

Hyaluronic acid (HA) fillers can almost always be dissolved with hyaluronidase, although highly cross-linked or long-standing fillers may require more than one session. Non-HA fillers such as Sculptra, Radiesse, silicone, and PMMA cannot be dissolved with hyaluronidase — they are managed differently and sometimes are not reversible. Knowing which filler you had is the essential first step.

How long does hyaluronidase take to work?

Hyaluronidase begins working within minutes. Most visible change appears within 24 to 48 hours, with further settling over the following week. Some cases need a second session, particularly for older or more cross-linked filler. Re-injection of new filler, if planned, should usually wait at least two to four weeks for tissues to settle fully.

Can anti-wrinkle injection complications be reversed?

Unlike filler complications, anti-wrinkle complications cannot be reversed pharmacologically — there is no equivalent of hyaluronidase for botulinum toxin. However, they resolve completely on their own as the product wears off, typically over three to four months. In the meantime, certain strategies (eye drops for eyelid drop, careful timing of further treatment for asymmetry) can sometimes help.

How do I know if I’m having a complication or just normal swelling?

Normal post-treatment swelling settles over a few days, is symmetrical, is not severely painful, and does not change colour beyond gentle bruising. Concerning features include severe or worsening pain, asymmetric or rapidly progressing swelling, white or purple skin, mottled discolouration, fever, or any change in vision. If in doubt, contact your treating practitioner — a brief phone call is always reasonable.

Does dissolving filler hurt?

Most patients describe it as similar to having filler placed — a brief stinging sensation as the medication is injected. Topical anaesthetic can be used, and discomfort settles quickly. Bruising and short-term swelling are common afterwards. The procedure itself is not the difficult part for most patients — the harder part is the wait through the settling period.

Can I have filler again after dissolving?

Usually yes — but only once all inflammation has fully resolved. Typically two to four weeks, sometimes longer. Re-injecting too soon risks recreating the issue you came to fix. The consultation before re-injection is a useful chance to talk honestly about why the previous treatment did not work, and what to do differently this time.

What should I look for in a practitioner to avoid complications?

Medical qualifications first — GMC, NMC, GDC, or GPhC registration with prescriber status. Save Face listing. ACE Group membership is a strong positive signal. A genuine consultation process, not a same-day sales experience. Adrenaline and emergency equipment on site. A clear answer to the question ‘what would you do if something went wrong with my treatment today?’ If a practitioner can answer all of these confidently, you are in safer hands.

How long do I have to act if I think I have a vascular occlusion?

This is genuinely time-critical — the optimal window for treating a vascular occlusion is the first few hours, and outcomes deteriorate the longer treatment is delayed. If you are experiencing severe pain, skin discolouration, or any visual change after filler, do not wait until the morning. Contact your practitioner immediately or go to A&E. It is always better to be assessed and reassured than to have waited.

Will my old practitioner be told if I come for a corrective consultation?

Only with your explicit consent. I will not contact your previous practitioner without your permission. Some patients want their original practitioner informed (particularly if there has been a complication that they should know about for their own learning and patient safety); others prefer the consultation to be completely confidential. Either is fine.

Is corrective treatment covered by my insurance?

Most private medical insurance does not cover aesthetic treatments or their corrections. The NHS does not provide hyaluronidase for the management of complications from private aesthetic treatments, except in true medical emergencies. This is one of the reasons it matters so much who placed the filler in the first place — and whether they are equipped to manage their own complications without onward cost to you.

The Takeaway

Aesthetic complications are not common, but they are also not as rare as the industry sometimes implies. The single biggest factor in how a complication resolves is who is managing it — their qualifications, their equipment, their experience, and their honesty. This is true at the point of the original treatment, and even more true at the point of correction.

If you are dealing with a complication or a disappointing outcome right now, the most important thing you can do is have an honest conversation with a medically qualified clinician. The conversation might end with treatment. It might end with reassurance. It might end with a recommendation to wait, or to seek a second opinion elsewhere. All of these are valid outcomes — the wrong outcome is silence, panic, or unnecessary further treatment.

If you are choosing a clinic for your first or next treatment, please use the checks in section 7. They take a few minutes, and they meaningfully change the odds. Worthing has very good aesthetic practitioners working to high standards — and it also has practitioners working to standards I would not be comfortable with. The framework above helps you tell them apart.

Whatever stage you are at, the door at Blue Bird Aesthetics is open for a calm, considered, commitment-free conversation. I take corrective work seriously, and I treat patients who come to me about something that has not gone well with the care and the honesty the situation calls for.
