How hyaluronic acid fillers work
Hyaluronic acid is a sugar molecule your body already makes; it binds water and gives tissue volume. Filler is a cross-linked HA gel — the degree and type of cross-linking sets how firm or soft it is, how much it lifts, and how long it lasts. A firmer gel deep on bone gives structural support (cheek, chin, jaw); a softer gel placed superficially refines fine areas (lips, tear trough). Placed correctly, it integrates with the tissue and looks and moves naturally.
Product is chosen for the job
There’s no single “best filler”. The right choice depends on the area, the depth, how much lift is needed and your tissue — which is why a serious injector works from a range, not one syringe.
Areas, results and longevity
| Area | What it does | Typical longevity |
|---|---|---|
| Cheeks / midface | Restores volume and lift; softens under-eye and nasolabial area indirectly | 12–18 months |
| Chin | Balances profile, improves proportion and jaw definition | 12–18 months |
| Jawline | Definition and contour; can soften early jowling | 12–18 months |
| Lips | Hydration, subtle volume, shape and border definition | 6–12 months |
| Tear trough | Softens the under-eye hollow (careful case selection only) | 9–18 months |
| Nasolabial folds / marionette lines | Softens static folds, usually via midface support first | 9–15 months |
| Temples | Restores upper-face volume, supports brow | 12–18 months |
| Non-surgical rhinoplasty | Camouflages a dorsal bump, refines tip angle (higher-risk area) | 9–18 months |
Longevity is affected by product, area movement, metabolism and how much was placed. Some areas need a small top-up at 4–6 weeks.
The “less is more” approach
The overfilled look almost never comes from a single conservative treatment. It builds up from repeated syringes, treating one area without balancing the face, placing product in the wrong plane, or not accounting for filler that’s still there from previous years (HA can persist longer than people assume). A good plan:
- Assesses the whole face and agrees priorities.
- Treats the structural area first (often the midface) before chasing a fold or a feature.
- Uses the smallest amount that achieves the goal, and reviews at 2–4 weeks before adding.
- Tracks lifetime filler by area so it doesn’t silently accumulate.
- Is willing to say “you don’t need filler here” — or “you need less, or a different treatment”.
Illustrative midpoints of the ranges above. Areas with more movement (like the lips) tend to break down faster than structural areas placed on bone.
Safety: vascular risk and how it’s managed
The most serious complication is vascular occlusion — filler entering or compressing an artery, cutting off blood supply to skin or, very rarely, the eye. It’s uncommon, but it’s why injector training and preparation matter enormously.
| Measure | Why |
|---|---|
| Medical injector with anatomy training | Knows the danger zones and safe planes |
| Aspiration / slow, low-pressure injection / cannula in higher-risk areas | Reduces the chance of intravascular placement |
| Hyaluronidase on site + a written emergency protocol | Allows immediate treatment if occlusion is suspected |
| Recognising early signs (blanching, disproportionate pain, dusky skin) | Time is critical — hours matter |
| Conservative volumes, avoiding heavily scarred tissue | Lower pressure, fewer surprises |
After treatment, seek urgent review if
You develop severe or increasing pain, skin that goes white then mottled or dusky, blistering, or any change in vision. These need same-day assessment by your injector or an emergency service.

Book a consultation. We’ll assess your proportions, tell you what will and won’t help, and give you a conservative plan and honest pricing.
Dissolving filler
Hyaluronidase is an enzyme that breaks down HA filler within a day or two. It’s used to treat complications, to correct overfilling or lumps, or simply because you don’t like the result. It dissolves the filler in the area treated (and can affect a little of your natural HA temporarily), and there’s a small allergy risk, so a patch test may be done. You can re-treat conservatively about two weeks later once swelling settles.
What it costs in London
| Treatment | Typical London price |
|---|---|
| Lip filler (0.5–1 ml) | £250–£450 |
| Cheek / midface (per ml) | £300–£550 |
| Chin / jawline (per ml) | £300–£550 |
| Tear trough (per ml, careful selection) | £400–£700 |
| Non-surgical rhinoplasty | £400–£800 |
| Hyaluronidase (dissolving) per area | £150–£350 |
Per-ml pricing varies with product and injector seniority. A conservative plan often uses less than you expect. Confirmed in writing after assessment.

Frequently asked questions
How much do dermal fillers cost in Knightsbridge?
Lip filler is typically £250–£450 for 0.5–1 ml, and cheek, chin or jawline filler £300–£550 per ml in London. Tear trough and non-surgical rhinoplasty are higher (£400–£800). Dissolving with hyaluronidase is £150–£350 per area. A conservative plan often uses less product than expected.
Will filler make me look overdone?
Not from a single conservative, well-planned treatment. The overfilled look builds up from repeated syringes, treating one feature in isolation, the wrong injection plane, or old filler accumulating. A good injector assesses the whole face, uses the minimum needed, and reviews before adding more.
What is the most serious risk?
Vascular occlusion — filler blocking or compressing an artery. It’s rare, but it can damage skin or, very rarely, vision. It’s why you should choose a medically trained injector who carries hyaluronidase and has a written emergency protocol.
Can filler be removed if I don’t like it?
Yes — hyaluronic acid filler can be dissolved with hyaluronidase within a day or two. It’s used for complications, overfilling, lumps or simply an unwanted result. You can re-treat conservatively about two weeks later once swelling settles.
How long does filler last?
Roughly 6–18 months depending on the area and product — lips at the shorter end because they move a lot, structural areas like cheeks and jaw at the longer end. Some HA can persist longer than the “marketing” duration, which is why lifetime tracking matters.
Does filler migrate?
Visible spread beyond the intended area (for example above the lip border) is usually the result of overfilling or superficial placement rather than the product “travelling” on its own. Conservative volumes and correct technique largely prevent it, and it can be dissolved.
Is filler painful?
Most fillers contain local anaesthetic, and numbing cream or a dental block is used for sensitive areas like the lips. Expect pressure and brief stinging. Swelling and some bruising for a few days afterwards are normal.
What areas should be treated first?
Usually the structural midface. Supporting the cheeks often improves the under-eye area and nasolabial folds indirectly, so chasing those folds directly with lots of product is frequently the wrong first move.
Can I have filler with anti-wrinkle injections or skin boosters?
Yes — they address different things: filler for volume and contour, anti-wrinkle injections for expression lines, skin boosters for skin quality. They’re commonly combined, usually spaced a couple of weeks apart.
Who should not have filler?
It’s avoided in pregnancy and breastfeeding, over active skin infection or inflammation in the area, and with certain autoimmune conditions or known hypersensitivity. Blood thinners increase bruising and need to be discussed. A full history is taken at consultation.
