Dermal fillers: how long do they actually last?

The honest answer is that most hyaluronic acid dermal fillers last between six and eighteen months, but that figure hides a lot of detail. Lips fade fastest because they move all day. Cheeks, chin and jawline hold longer because they sit on bone and barely move. Your metabolism, your training schedule and even the type of filler used all pull the figure up or down by months at a time.

Below is what the peer-reviewed evidence actually says about filler duration, area by area, and how we plan it for every new patient at CoLaz dermal fillers appointments.

How long do dermal fillers last in general?

Most hyaluronic acid dermal fillers last between six and eighteen months. The two ends of that range correspond roughly to the two ends of the face: lips at six months, deep cheek and jaw augmentation at eighteen months or more.

The mechanism is simple. Hyaluronic acid is a sugar molecule that already exists naturally in your skin, and your body breaks it down with an enzyme called hyaluronidase. The filler used in injectables is cross-linked, meaning the sugar chains are bonded together in a way that slows that breakdown. The more cross-linking, the longer the gel persists.

So when a clinic says “filler lasts twelve months,” what they really mean is “this filler, in this area, on an average patient, has been shown in clinical trials to still be detectable in tissue at the twelve-month mark.” That is a useful planning estimate, not a promise.

How long do lip fillers last?

Lip fillers typically maintain their full result for about six months, with the visible benefit fading over the second half of the year. A 2021 meta-analysis of hyaluronic acid lip augmentation found that 91% of patients showed improvement at two months, 74% at six months, and 46% at twelve months.

The reason the lips fade faster than other areas is constant motion. The orbicularis oris muscle that surrounds the mouth contracts every time you eat, drink, speak, smile or kiss, which mechanically breaks down the filler over time. Blood flow to the lip is also relatively high, which speeds up enzymatic clearance of the hyaluronic acid by your body’s own hyaluronidase.

In practice, most patients see the lip volume they wanted at two weeks, settle into the final look at four weeks, and start to notice gradual softening at five to six months. A small top-up at six months keeps the result steady for far longer than waiting for a full top-up at twelve.

A separate longer-term study on a newer-generation HA lip filler tracked patients for eighteen months and found 67% of patients without any retouching still showed a satisfactory result. The curve is gentler with modern products, but the pattern is the same: lips need the most frequent maintenance of any filler area.

How long do cheek, chin and jawline fillers last?

Cheek, chin and jawline fillers typically last 12 to 18 months because the area sits over bone, moves much less than the lips, and is usually treated with a firmer, more cross-linked gel designed for structural support.

The pattern across the lower and mid-face is consistent: less movement means slower mechanical breakdown, deeper placement means slower enzymatic clearance, and firmer fillers carry more cross-linking which extends durability further. A Frontiers in Surgery meta-analysis found durable results in stable areas, with significant decay only emerging after the one-year mark for cheek and jawline placements.

Cheeks and chin “feel” like they last longer because the change is structural. When we add filler to the cheekbone or jaw angle, we restore volume to bony landmarks that have lost projection with age. Even after the filler has broken down, the soft tissue around it sits in a slightly different position, so the face does not snap back to its starting point overnight. Lips do not behave like that; once the gel has gone, lips return to baseline.

In planning terms, most patients top up cheek and chin filler every 12 to 18 months, and we discuss the maintenance interval at the second review visit, not at the first appointment.

What makes fillers wear off faster or slower for you specifically?

Five things change how long a filler lasts on your face. None of them is your age, which surprises a lot of patients.

1. Where the filler is placed. Movement is the single biggest variable. Lips and nasolabial folds break down filler faster than cheeks or jawline because those areas barely move.
2. The type of filler. A soft, low-cross-linked gel for fine lines breaks down in 6 to 9 months. A firm, highly cross-linked gel for structural cheek augmentation can last 18 to 24 months.
3. Your metabolism. People produce hyaluronidase at different rates. Patients with faster metabolisms see fillers fade sooner.
4. Your exercise level. Regular intense cardio accelerates filler clearance, usually by a month or two.
5. Sun exposure and skin quality. Heavy UV exposure shortens how natural the filler looks even before it has broken down. Daily SPF 30 protects both the result and the skin underneath.

These are not reasons to avoid filler. They are reasons not to trust a single “filler lasts X months” figure from any clinic that has not met you.

What can be done if filler does not settle the way you wanted?

Hyaluronic acid fillers can be partially or fully dissolved using hyaluronidase, the same enzyme your body produces naturally. This is one of the main advantages of HA fillers over permanent or semi-permanent alternatives and is part of why we use them as our default.

A 2024 review of hyaluronidase use in aesthetic practice sets out the standard approach: low to moderate doses are used to correct non-emergency issues such as a small lump, an asymmetry or a result the patient is unhappy with. Reassessment between sessions allows the clinician to titrate the dose. For non-inflamed nodules, the baseline guidance is around 5 units of hyaluronidase per 0.1 mL of filler at standard concentration, with higher doses needed for highly cross-linked products.

In the rare emergency case of a vascular occlusion (where filler partially blocks a blood vessel), the same enzyme is used at high doses urgently. A systematic review of vascular complications confirms that early, high-dose hyaluronidase typically resolves cutaneous ischaemia and is the cornerstone of emergency treatment. This is one of the main reasons HA fillers should only ever be administered in a clinic that keeps hyaluronidase on site and has a written emergency protocol.

If a patient comes to us after a treatment elsewhere and is unhappy with the look, we will assess whether dissolving the existing filler is appropriate before placing anything new.

Is it safe to keep topping up dermal fillers long-term?

Topping up dermal fillers every 12 to 18 months is safe when the work is done by an experienced practitioner who is reassessing your face at each visit, not just adding to what is already there.

The NHS guidance on dermal fillers sets out the headline patient-safety principles: check your practitioner is on an accredited register, expect a thorough consultation, understand the risks, and report any side effects through the Yellow Card scheme. These principles apply to your first treatment and every top-up that follows.

The risks of long-term filler use are worth knowing: vascular events (rare but serious), nodule formation, migration of product, biofilm infection, and the cosmetic risk of the face becoming “over-filled” over many cycles if no one is mapping the cumulative volume. The way to manage all of these is to stay with a single clinic, keep a record of what was injected and where, and reassess the whole face every 12 to 18 months.

UK regulation is also tightening. The House of Commons Library briefing on regulation sets out the proposed licensing framework, and the Department of Health consultation puts most facial dermal fillers in the “amber” category, meaning non-healthcare practitioners will be allowed to deliver them only under the supervision of a regulated healthcare professional once the scheme is in force.

How does CoLaz plan your treatment?

Every new dermal filler patient at CoLaz starts the same way: a free consultation with the prescribing clinician, a written treatment plan with the exact filler type and volume for each area, and a review visit two to four weeks after the first treatment to confirm the result has settled the way we both wanted.

A few principles we apply at every visit:

• One area at a time, where possible. A patient asking for “cheeks, chin, lips and jawline” in a single appointment is usually better served by treating in two sessions, four to six weeks apart, so we can see how each area settles before adding to the next.
• Less than you think, especially first time. We would rather under-treat at the first appointment and add at the review than over-treat and need to dissolve. Filler that has been placed cannot easily be moved; only dissolved and restarted.
• Hyaluronidase always on site. Every CoLaz clinic carries hyaluronidase and a written emergency protocol. The clinician treating you can authorise its use immediately if it is needed.
• No fixed packages. We do not sell six-month or twelve-month “membership” packages. The timing of your top-up is decided when we can actually see how your filler has worn down, not before.

We are registered with the JCCP and follow the standards published on Save Face, both Professional Standards Authority-recognised registers. Every clinician administering filler at CoLaz works to those standards.

If you want to find out what your specific filler plan would look like, the consultation is free at every CoLaz clinic. You will leave with a written plan, a confirmed price, and a review appointment, and we will not inject on the same day unless you have had a clear opportunity to ask every question first.
