Why the range is so wide
Hyaluronic acid filler is broken down gradually by your body's own natural processes, and three things decide how fast.
Movement. The more an area moves, the faster the product breaks down. Mechanical work on a gel shortens its life, which is why the mouth is at one end of the range and the mid-face at the other.
Blood supply. Well-perfused tissue clears filler faster, because the enzymes that break down hyaluronic acid arrive with the blood.
The product. Firm, cross-linked gels built to hold structure last considerably longer than the soft, fine gels used where the tissue is thin and mobile. That is a design difference, not a quality difference.
Your own metabolism plays a part too, along with your skin type and skin thickness, and it is the variable nobody can predict in advance. If your filler has historically not lasted as long as you expected, tell your practitioner, because it changes how they plan.
One thing worth knowing about where the clock starts. What you see on the day is filler plus swelling, and the two look quite different. Swelling settles over about two weeks and the product integrates over two to four, so recovery and result are not the same thing. Count from the two week mark rather than from the appointment.
How long filler lasts in each area
Lips: nine to eighteen months. Constant movement and a generous blood supply put lip fillers at the shorter end. Lip augmentation for fuller lips is the treatment people repeat most often, and that is anatomy rather than a sign anything has gone wrong.
Around the mouth: nine to twelve months. Nasolabial folds, marionette lines and perioral lines such as vertical lip lines sit in tissue that moves with every word and every meal.
Cheeks and midface: twelve to eighteen months. Cheek augmentation sits over bone in tissue that barely moves, and the products used there are firmer.
Jawline and chin: up to twenty-four months. Jawline and chin fillers are built with firm structural gels, which last longest of all. Chin filler and jawline contouring are the treatments people repeat least often, and the same applies to jowl filler treatment, which works by restoring support above the jawline rather than filling the jowl itself.
Tear troughs: at the longer end. The under-eye area moves very little, so under-eye fillers, used for hollowing and dark circles, tend to outlast filler placed lower on the face.
Nose: towards the top of the range. Non-surgical rhinoplasty uses very small amounts of firm product in an area that barely moves, which is why it is one of the longest-lasting filler treatments.
Upper face lines such as crow's feet and forehead lines are usually treated with anti-wrinkle injections rather than filler, because they are caused by muscle movement rather than lost volume.
The product matters as much as the area
Not all dermal fillers at our Harley Street clinic are the same, and the filler material chosen for you is chosen for the job rather than out of habit.
- Soft, fine gels for fine lines, lip detail and subtle hydration. Shortest lasting by design, because a firm product in thin mobile tissue looks and feels wrong.
- Medium gels for general volume and softening folds.
- Firm, structural gels for jawline, chin and cheek support. Longest lasting, and the reason structural work is repeated least often.
We use the Juvéderm range, and the specific product is matched to the treatment area at your consultation. Using a firm gel where a soft one belongs is one of the more common reasons a result looks obvious, and using a soft one where structure is needed is why some results fade faster than the patient expected.
Injection technique matters just as much. Depth, placement and how evenly the product is distributed decide whether a result looks balanced and whether its symmetry holds as it settles. Two people using the same filler material in the same area can produce very different outcomes, which is why the injector is a bigger variable than the brand on the syringe.
Do fillers last longer than Botox?
Considerably, and the two are not really comparable.
Filler lasts several times longer than anti-wrinkle injections, because the two work in completely different ways: botulinum toxin relaxes a muscle, and the muscle recovers on its own schedule, while filler is a gel that sits in the tissue until your body breaks it down.
That is also why they are often used together rather than instead of each other. Lines caused by movement respond to toxin. Volume that has been lost responds to filler. Treating one with the other is the most common reason a result disappoints.
What the imaging evidence changed
There is a distinction worth understanding, because almost nobody explains it.
How long you can see the result and how long the product is present are not the same thing.
A 2024 review of 33 magnetic resonance imaging studies found hyaluronic acid filler in the mid-face still detectable two years after treatment, and in some cases considerably longer. That does not mean the cosmetic effect lasted two years. It means small amounts of product persist after the visible result has faded.
It is not a reason to avoid filler. It is a reason to be thoughtful about how much goes in and where, because a decision made today lasts longer than the industry once assumed. It is also why we would rather under-treat and add at review than place more than an area needs.
What shortens your result
- Smoking. Reduces blood supply to healing tissue and accelerates the breakdown of hyaluronic acid.
- Significant sun exposure. UV degrades collagen and hyaluronic acid.
- High-intensity exercise. A consistently raised metabolic rate clears filler faster. This is not a reason to train less.
- Significant weight loss. Facial volume changes with body weight, and a result planned at one weight may not suit another.
And what extends it:
- Daily SPF, which is the single most useful habit for making a result last.
- Consistent skincare, because filler sits in skin and the condition of that skin affects how the result reads.
- Adequate hydration, since hyaluronic acid binds water.
- Not topping up too early, which matters more than any of the above.
Knowing when to come back
Filler fades gradually rather than disappearing. What people notice first is usually subtle: the cheeks look a little flatter in photographs, the jawline softens, lips lose their edge.
The useful test is not how you looked the week after treatment. It is whether you now look close to how you did before you started.
Topping up too early is the most common mistake, and it is how people end up looking overfilled without anyone ever deciding to overfill them. Adding product while the previous treatment is still present means building on what is already there, and doing that repeatedly is what produces a face that has drifted rather than been treated.
Most people maintain a result with a top up once the original treatment has largely worn off, rather than adding to it while it is still there. Maintenance is usually a smaller treatment than the first one, because you are restoring a result rather than building it.
A review at nine to twelve months is a sensible rhythm for most people, even if the answer at that appointment is that nothing needs doing yet. That is a legitimate outcome and we will tell you so.
You do not have to wait
One thing worth knowing: hyaluronic acid filler is reversible.
An enzyme called hyaluronidase breaks it down within days, whether the reason is a complication, migration, or simply deciding you would rather not have it. That is not possible with permanent fillers, which is why we do not use them.
So the nine to twenty-four month figure is a ceiling rather than a commitment. If you decide at month four that a result is not for you, you do not have to live with it until it wears off.
Book a dermal filler consultation
The honest answer to how long yours will last is that your practitioner will have a much better idea once they have seen your face, your existing volume and what you are trying to achieve.
Book a consultation with our practitioners at PHI Clinic on Harley Street. They will review your medical history, assess your facial anatomy, and set out a treatment plan, including cost, with a realistic interval for you rather than a general figure.
If you are considering dermal filler treatment in London, whether the aim is to rejuvenate the mid-face or simply to soften one thing that has started to bother you, that conversation is where it starts.
