Most people who book their first filler appointment are not particularly worried about the treatment itself. They have read about the numbing cream, they know the needle is fine, they have accepted that there will be a moment of pressure. What keeps them awake is the following morning. Will there be a bruise? Will someone at the 9am meeting notice? Is there any chance of walking into the office looking obviously swollen?
It is a reasonable question, and it deserves a proper answer rather than a vague reassurance that “downtime is minimal”. What follows is an honest, hour-by-hour account of what typically happens in the first 48 hours after dermal filler treatment at our Fitzrovia clinic, what settles on its own, the short list of things worth avoiding, and the small number of signs that warrant a phone call rather than a wait-and-see approach.
Why aftercare matters more than most people expect
Filler is placed into living tissue. Tissue responds. The hyaluronic acid gel itself is well tolerated, but the act of placing it involves a needle or cannula passing through skin and, in some areas, close to small blood vessels. Mild swelling is the body doing exactly what it should. Bruising, when it happens, is simply a vessel that has been nudged.
What you do in the 48 hours afterwards has a genuine influence on how quickly all of this settles. Heat, alcohol, strenuous exercise and pressure on the treated area all prolong the process. Rest, cool compresses and a bit of patience shorten it. None of this is complicated, but it does need explaining properly, which is why every patient at Sheridan France leaves with written aftercare and a direct route back to the clinic if they have a question.
Conservative treatment recovers faster
There is a link between technique and recovery that is rarely discussed openly. A treatment that uses a measured volume, placed at the correct depth, in the right anatomical plane, disturbs less tissue than one that overfills a region in a single sitting. Less disturbance means less swelling, fewer bruises and a result that looks settled sooner.
Sheridan’s approach has always favoured building gradually and reviewing, particularly for first-time patients. It suits the natural-results philosophy the clinic is known for, and it happens to be kinder to your diary as well. Results vary from patient to patient depending on anatomy, lifestyle and aftercare.
The first 48 hours, hour by hour
Hours 0 to 2: immediately after treatment
You will see a result straight away, and it will look slightly fuller than the final outcome. This is normal. The area may feel firm, warm or mildly tender. Small pinpoint marks at the injection sites are common and usually fade within an hour or two. Some patients notice tiny raised bumps where product has just been placed; these typically soften as the gel integrates with the surrounding tissue.
Lips swell more than anywhere else. The lip is highly vascular with loose tissue that holds fluid readily, so if you have had lip filler, expect the immediate appearance to be noticeably fuller than what you will settle into. Do not judge anything on day one.
Hours 2 to 12: the swelling peak
This is usually when swelling after dermal filler reaches its height, often overnight or first thing the next morning. Lying flat encourages fluid to pool, so an extra pillow helps. A cool (not frozen) compress applied gently for ten minutes at a time can be genuinely useful during this window.
Cheeks and the jawline tend to swell far less dramatically than lips. Tear trough and under-eye work can look puffy for a few days because the skin there is thin and the tissue holds fluid. Bruising, if it is going to appear, often becomes visible in this period.
Hours 12 to 24: the morning after
For most patients treated in the cheeks, chin, jawline or naso-labial folds, this is the point where the treatment stops announcing itself. You may see mild asymmetry, which is almost always uneven swelling rather than uneven placement. Any bruise present is usually small and cosmetically manageable with concealer once the injection points have fully closed, generally after twelve hours.
Lip patients should plan for this being the most visible day. If you have an event, a photograph or a presentation, book your treatment at least two weeks ahead rather than two days.
Hours 24 to 48: settling
Swelling drops off appreciably in the second 24 hours. Tenderness on touch fades. If there are firm areas, they usually soften over the following one to two weeks as the product settles and integrates. By 48 hours the majority of patients are comfortable returning to their normal routine, including light exercise and their usual skincare.
Filler recovery time in London terms, for the way most people actually live, means roughly one quiet evening, one careful day and then back to normal.
What not to do after filler
The list is short and, for the most part, only applies for a day or two.
- Avoid heat for 48 hours. No saunas, steam rooms, hot yoga or very hot showers directed at the face. Heat increases blood flow and prolongs swelling.
- Skip strenuous exercise for 24 to 48 hours. A walk is fine. A spin class the same evening is not.
- Leave alcohol for 24 hours. Alcohol thins the blood and makes bruising more likely and more visible.
- Do not massage or press the area unless you have been specifically instructed to do so by your practitioner.
- Sleep on your back for the first night where you can, particularly after cheek or lip treatment.
- Hold off on makeup over the injection sites for around twelve hours to reduce infection risk.
- Postpone facials, microneedling, laser and dental work for two weeks.
- Avoid long-haul flights for 24 to 48 hours if your schedule allows, as cabin pressure can accentuate swelling.
Equally useful is what you should do: drink water, eat normally, take paracetamol if you are uncomfortable (avoiding anti-inflammatories such as ibuprofen in the first day or so unless a doctor has advised otherwise, since they can encourage bruising), and resist the urge to examine the area every hour in the bathroom mirror.
How long does filler swelling last?
For most areas, visible swelling resolves within two to three days. Lips are the exception and can take up to a week to look fully settled, occasionally a little longer. Under-eye treatment may take one to two weeks to look its best. Bruises, where they occur, generally fade over five to ten days and respond well to arnica and concealer.
The final result of any filler treatment is best judged at two weeks. That is the appropriate point for a review, which is why the clinic offers one. Making decisions about “adding more” before that mark is how patients end up overfilled.
When to call rather than wait
Complications from hyaluronic acid filler are uncommon in experienced medical hands, but every patient should know what to look out for. Contact the clinic promptly if you notice any of the following.
- Severe or escalating pain that is out of proportion to the treatment, particularly if it worsens after the first few hours.
- Skin that turns white, dusky, grey or mottled in the treated area or nearby.
- Any change in vision, or pain around the eye.
- Increasing redness, heat, spreading swelling or discharge after the first 48 hours, which may suggest infection.
- Firm, tender lumps developing days or weeks later.
These are rare, but they are time-sensitive. As an Independent Nurse Prescriber, Sheridan holds the medication and the training required to manage vascular complications, and patients have a direct line to the clinic rather than a call centre. That matters more than most people realise when choosing where to have treatment.
Why Patients Choose Sheridan France
Sheridan France has practised in facial aesthetics for over twenty years. She holds an MSc, is a Registered Nurse and an Independent Nurse Prescriber, a combination that remains unusually strong within the aesthetics sector. Her training was completed with Plastic Surgery Partners on Harley Street, The Consulting Suite on Portland Place, and with the late Dr Frederic Brandt in Coral Gables, a practitioner whose influence on modern injectable technique is still widely acknowledged.
That background shapes a consistent philosophy: restore what has softened, respect the underlying anatomy, and stop before the face starts to look treated. Patients regularly tell us the point was to be told they look well, not to be asked what they have had done. The clinic holds a 4.9 rating from more than 339 Google reviews, which we take as a reflection of that restraint rather than anything louder.

Frequently Asked Questions
Can I go back to work the same day after dermal filler?
Most patients treated in the cheeks, chin, jawline or naso-labial folds return to work the same day or the next morning without difficulty. Lip filler is more visible in the first 24 to 48 hours, so if you have a significant meeting or event, allow at least two weeks between treatment and the date.
How can I reduce bruising after filler?
Avoid alcohol, fish oils and non-essential blood-thinning supplements for a few days beforehand (never stop prescribed medication without speaking to your GP), apply a cool compress afterwards, sleep slightly elevated on the first night and consider arnica. Bruising is unpredictable and can happen to anyone, but these steps reduce the likelihood.
Is it normal to feel small lumps after filler?
Mild firmness or small palpable areas in the first week or two are common as the product settles and integrates with the tissue. These typically soften on their own. If a lump remains firm, tender or visible at the two-week review, it can be assessed and, where appropriate, managed in clinic.
When will I see my final filler result?
Two weeks is the reliable point. Swelling has resolved, the product has integrated, and what you see is what you have. Any decision about refining or adding volume should be made at that stage, not sooner.
Can filler be reversed if I am unhappy?
Hyaluronic acid fillers can be dissolved with an enzyme called hyaluronidase, administered by a qualified prescriber following consultation. It is reassuring to know the option exists, though careful, conservative placement makes it rarely necessary.
