Lip filler is a hyaluronic acid injection that adds volume, definition or balance to the lips, and the best results come from a treatment plan built around your face rather than a set number of millilitres. At NexGen Clinic in Cambridge, lip fillers start from £160, and every treatment begins with an individual assessment so the amount and placement suit your features and your goals.
This guide covers what lip filler does, how the appointment runs, how long it lasts, what it costs in the UK, how to think about 0.5 ml versus 1 ml, and the safety points worth knowing before you book.
TL;DR
- Lip filler is a hyaluronic acid injection that adds volume, smooths lines around the mouth and can correct mild asymmetry. Results are temporary.
- It typically lasts 6 to 18 months, depending on the product and the area treated.
- UK prices in 2026 are about £250 to £600 per syringe. Our lip fillers start from £160.
- A smaller, staged approach usually looks more natural than one large treatment.
- Choose a qualified, medically led practitioner and know the warning signs of a rare but serious complication.

What lip filler is and what it can change
Lip fillers are injections of synthetic hyaluronic acid, a gel-like substance that holds water. Cleveland Clinic describes them as a way to add volume, correct lip asymmetry and smooth wrinkles around the mouth.
In practice, people ask for different things:

- Volume: lips that have always been thin, or that have lost fullness with age.
- Definition: a clearer outline, especially around the border of the upper lip.
- Balance: evening out one side that sits flatter than the other, or bringing the upper and lower lip into proportion.
- Smoother texture: softening fine vertical lines above the lip.
Satisfaction in small studies is high. In a case series of 13 patients, over 92% reported significant improvement in appearance. That is a small sample, so treat it as an indication rather than a guarantee. What it does show is that, when the aim is well defined, lip augmentation can meet it.
Lip filler is not one look
The phrase "lip filler" covers everything from a barely noticeable refresh to a dramatic change. Most of our clients, from busy professionals to brides and wedding guests, ask for something that looks like their own lips on a good day. That is the brief we plan around: natural movement, facial harmony and no more product than is needed.
How the appointment works
A good lip filler appointment is mostly conversation and planning, with a short injection phase.
- Consultation. We look at your lip shape, your skin, your face as a whole and what you want to change. This is also the time to talk about your medical history, any medication and any previous filler.
- Planning. We agree what to treat and how much. If a smaller amount will do the job, we say so.
- Numbing. A topical anaesthetic is usually applied first. Cleveland Clinic notes that a nerve block may also be used in some cases.
- Injection. The filler is placed with a thin needle. Depending on the plan, the whole procedure can take anywhere from 30 minutes to two hours.
- Review. We check symmetry and feel of the lips, and go through aftercare.
If you are attending an event, schedule the appointment well ahead of it. Lips can look and feel different in the first days, so you want time for things to settle before the photographs.
What recovery looks like
Some swelling, tenderness and occasional bruising are common after lip filler. Standard recovery advice includes avoiding lip products and exercise for at least 24 hours and using ice for swelling.
Our own guides go into more detail on each stage:
- Lip filler swelling: stages, timeline and how to manage it
- Lip filler aftercare: essential guidance for optimal results
- Filler aftercare: your first 48 hours and beyond
If you are busy and want low downtime, plan the first 48 hours with fewer commitments. Skin quality also plays a part in how lips look. If you are curious how collagen and hyaluronic acid differ in the skin, this article on collagen and hyaluronic acid roles sets out what each does.
How long lip filler lasts
The Joint Council for Cosmetic Practitioners (JCCP), the UK body that sets standards for the cosmetic sector, says dermal filler should last between 6 and 18 months on average, depending on the product and the area treated. Lips are a mobile area, and filler in mobile tissue tends to last less time than filler placed over bone.
In practice, how long yours lasts depends on:
- the product chosen and how it is placed;
- how much was used;
- how active your lips are (talking, expressions, exercise);
- your own metabolism.
Because results are temporary, many people plan top-ups or a review appointment. We would rather you return for a small adjustment than build up volume you did not want.
How much does lip filler cost in the UK?
Prices vary with the practitioner's qualifications, the product and the amount. Cosmetic Journal puts the typical UK cost in 2026 at about £250 to £600 per syringe.
At NexGen Clinic, lip fillers start from £160, and dermal fillers from £180. The final amount depends on what your assessment shows you need. You can see the range of treatments on our treatments page.
When comparing prices, compare like with like:
| What to compare | Why it matters |
|---|---|
| Amount of filler | A lower price may mean less product |
| Practitioner's qualifications | Training affects how well complications are recognised and managed |
| Consultation included | A proper assessment is part of safe care |
| Follow-up and review | Lips change as swelling settles |
0.5 ml or 1 ml: how to decide
There is no universal right amount. The amount depends on your starting lip size, your facial proportions, the look you want and how your lips respond. As a general principle, a smaller amount can create a visible but natural refinement, and you can add more later.
A conservative, staged plan has real advantages:
- you see how your lips settle before deciding on more;
- you keep proportion with your nose, chin and smile;
- you avoid the overfilled look many people say they want to avoid.
Our conservative ml guide to how much filler you need explains this in more depth. In your consultation we recommend the amount that fits your face, even if that is less than you expected.
Risks and warning signs
Most people have mild, short-lived effects such as swelling and bruising. Serious complications are uncommon, but you should know what they are. The main one is vascular occlusion, which can happen when filler is injected into or very close to a blood vessel. The BBC reports it can cause tissue death, skin damage, facial deformity or, rarely, blindness.
NHS-commissioned work by Health Education England noted that the true rate of complications may never be known because there is no systematic reporting. Experts increasingly recommend ultrasound mapping of facial blood vessels before injections, although it is not yet routine standard care across the UK.
If something feels wrong after treatment: contact the clinic that treated you immediately. Severe or worsening pain, changes in skin colour or any change in your vision need urgent medical attention, so call 999 or go to A&E for vision changes.
Our clinical journal covers this in detail in Dermal filler safety: what to check before you book.
UK rules you should know
The rules are changing, so it helps to know where things stand:
- Filler is a medical device, not a medicine. HEE explains that in the UK hyaluronic acid fillers are class III medical devices, with no legal requirement to provide safety and efficacy data or comparisons with other brands.
- Licensing is planned. The government has announced a local-authority licensing system for lower-risk cosmetic treatments, including fillers, with safety, training and insurance standards. Only qualified healthcare professionals will be able to perform the highest-risk procedures.
- Under-18s. In England, administering or arranging cosmetic filler for under-18s is an offence, with narrow exceptions for doctors and regulated professionals acting on a doctor's directions. Parental consent is no defence.
- Training benchmark. HEE's project highlighted that level 7 (postgraduate) qualifications should be a benchmark for practitioners delivering non-permanent dermal fillers, so they can recognise and manage emergencies.
Choosing a clinic
For a first-time client, the practical questions are simple. Who will treat me? Will I have a proper consultation first? Will the plan be explained in plain terms? Will I be told if I do not need treatment? At NexGen Clinic, our medically led approach is built on over 15 years of aesthetic experience, an individual assessment before every treatment and transparent recommendations.
If you are comparing lip filler with other options for a more natural, skin-led result, our dermal fillers page and our guide to natural-looking lip fillers in Cambridge are good starting points.

Our perspective
Lips are one of the most expressive parts of the face, and they are also the area where people most fear an unnatural result. We understand that. Our view is that good lip treatment starts with the whole face: your proportions, your skin quality, how you speak and smile.
With over 15 years of experience in aesthetics, we have learned that restraint is a skill. A modest, well-placed treatment that you can build on is almost always a better start than a large one. We would rather see you again for a small refinement than give you more than you need.
That is why every treatment at NexGen begins with an individual assessment, and why we combine established techniques with a modern, skin-health-focused approach. Honest recommendations, clinical judgement and natural-looking results are the standard we hold ourselves to.

FAQ
How long do lip fillers last?
On average, lip filler lasts between 6 and 18 months, according to the JCCP. The exact time depends on the product, the amount and how mobile your lips are. We review your results with you so any top-up is planned rather than rushed.
How much is lip filler in the UK?
Typical UK prices in 2026 range from about £250 to £600 per syringe. At NexGen Clinic, lip fillers start from £160, with the final price depending on your assessment and the amount recommended.
Should I choose 0.5 ml or 1 ml?
There is no single right answer, because it depends on your lips and your face. A smaller amount often gives a natural refinement, and you can add more later. We agree the amount with you in your consultation, and our guide to how much filler you need explains the thinking.
Is there a downside to lip fillers?
Swelling, tenderness and bruising are common in the first days. Rarely, filler can block a blood vessel, which needs urgent attention. Knowing the warning signs and being treated by a qualified, medically led practitioner is how you use lip filler safely.
Does lip filler hurt?
Most people describe pressure and some discomfort. A topical anaesthetic is usually applied beforehand, and a nerve block may be used in some cases. Tell us if you are anxious, and we will talk you through each step.
