What are lip fillers?
Lip fillers use hyaluronic acid, a substance your body produces naturally, to gently restore volume, improve definition and bring balance to the lips.
Done well, the effect is quiet rather than obvious. People notice you look well, without quite knowing why. At PHI Clinic we treat the lips as part of the whole face, not in isolation. Our practitioners are known for a measured, artistry-led technique, often placing a little less than you might expect at first and reviewing the result afterwards. It is a more considered way to work, and it is how we keep results looking natural.
What happens at a lip filler appointment?
- Consultation. We listen to your goals and assess your lip shape, facial balance and suitability.
- Comfort. Topical numbing is applied, and the Juvéderm filler also contains lidocaine.
- Treatment. Filler is placed with precision over 30 to 45 minutes, with frequent checks.
- Review. We see you again to assess your settled result and top up only if needed.

How much do lip fillers cost in London?
How much lip filler do you need, 0.5ml or 1ml?
Most first‑time patients have 0.5ml to 1ml. Half a millilitre is a subtle change, enough to hydrate, define the border and correct small asymmetries while leaving the lip close to its natural size. One millilitre gives noticeably more volume and is usually the most anyone needs in a single session.
We often start with less than you expect and review you at two weeks. Filler can always be added. Removing it means dissolving, which is straightforward but avoidable if the first treatment is measured.
What lip filler looks can you choose?
There is no single lip filler look. At your consultation we tailor the technique to your features and what you would like to achieve:
- Subtle enhancement. A small amount to softly hydrate and define, our most requested result.
- Russian lips. A vertical technique that gently lifts and heightens the centre of the lip while keeping the sides soft.
- Balanced volume. Even fullness across the lip body, for lips that still move and express naturally.
- Border definition. Refining a blurred lip outline, often with little or no added volume.
- Lip restoration. Replacing volume lost with age and softening fine lines around the mouth.
Considering a more subtle change first? You may wish to explore a lip flip with anti-wrinkle injections (and how long a lip flip lasts). Our guide to fuller lips without fillers covers this, along with skin boosters and skincare, in more detail.
Which lip filler do you use?
We treat lips with the Juvéderm Volbella range of hyaluronic acid fillers, chosen for their soft, flexible texture and natural feel. Juvéderm is one of the most clinically studied filler ranges in the world, and as an Allergan training clinic we work with it daily. Because it is hyaluronic acid, it is temporary and reversible, which we consider an important safety feature. We do not offer permanent or semi‑permanent fillers.

What is lip filler recovery like, day by day?
A little swelling is normal and not a reflection of your final result. A typical recovery looks like this:
- Day 0 to 1. Most swelling. Lips may feel firm and look fuller than the final result.
- Day 2 to 3. Any swelling or light bruising peaks, then begins to settle.
- Day 4 to 7. Lips soften and look more natural. Small lumps usually smooth out.
Around two weeks. Your settled result, and when we review you.
Is lip filler right for you?
Lip filler suits healthy adults who would like subtle enhancement or correction and feel comfortable with a natural, considered result. A consultation and full medical history always come first, and we will tell you honestly if it is not the right choice for you.
Lip fillers may not be suitable during pregnancy or breastfeeding, with an active cold sore or skin infection near the lips, a known allergy to hyaluronic acid or lidocaine, or certain autoimmune or bleeding conditions.
If your concern is naturally thin lips, vertical lip lines above the mouth, or a gummy smile, those pages explain what filler can and cannot change.
What are the risks of lip fillers?
No injectable treatment is without risk, and being open about that is part of responsible, doctor‑led care. Our guidance is consistent with NHS advice on dermal fillers.
- Common and temporary. Swelling, mild bruising, tenderness and small lumps that settle within one to two weeks.
- Uncommon. Asymmetry, longer‑lasting swelling, infection or a cold‑sore flare in those prone to them.
- Rare but serious. Vascular occlusion, where filler affects a blood vessel. It is a medical emergency, and it is precisely why lips should be treated by qualified medical practitioners. We keep hyaluronidase on site to act immediately if ever needed.
Can lip fillers be dissolved?
Yes. Because we use hyaluronic acid filler, it can be dissolved with hyaluronidase if you wish to reverse the result or in the rare event of a complication. We do not use permanent fillers.
How do you care for your lips after filler?
- First 24 hours. Avoid touching, massaging or applying makeup to the lips.
- 24 to 48 hours. Avoid strenuous exercise, alcohol, saunas and flights.
- To ease swelling. A cool compress helps, and sleeping slightly elevated does too.
- When to contact us. Contact us promptly if you notice blanching, increasing pain or a dusky colour, as these can signal a complication we will want to see quickly.

Lip fillers frequently asked questions
Our approach is to enhance your natural lip shape rather than change it. We often underfill at first and review you afterwards, so the result looks subtle and balanced.
Most people find it very tolerable. We apply a topical numbing cream and the Juvéderm filler we use contains lidocaine for comfort.
They are not suitable during pregnancy or breastfeeding, with an active cold sore or infection in the area, an allergy to hyaluronic acid or lidocaine, or certain autoimmune or bleeding conditions. A full medical history confirms your suitability.
No. They often look fuller than the final result for the first two or three days because of swelling, then settle. Your true result is visible at around two weeks.
Yes. We will ask what was used and when, and examine the lip before recommending anything. If previous filler is sitting poorly, dissolving first is sometimes the better route.
