It is the question I hear most often in my consultation room on Harley Street: once I have had my dermal fillers, how long will they actually last? The honest answer is that longevity varies more than most patients expect. It depends on the product used, the area treated, your own metabolism and how the filler was placed. In this guide I want to give you realistic timelines rather than marketing promises, so you can plan your treatment and your budget sensibly. Most of the fillers we use are hyaluronic acid based, which behave in a predictable way and, reassuringly, can be adjusted or dissolved if needed.
So how long do dermal fillers typically last?
For most hyaluronic acid fillers, results last somewhere between six and eighteen months. That is a wide range, and it exists for good reason. A soft, spreadable filler placed in the lips tends to break down faster than a firmer, more structured product placed deep on the cheekbone or jaw. As a rough guide I tell patients to expect around six to nine months for lips, nine to twelve months for the mid-face and nasolabial folds, and up to twelve to eighteen months for cheek and jaw contouring where a denser gel is used. These are averages, not guarantees. Some people metabolise product quicker, others hold onto it longer than the textbook suggests.
Why does filler last longer in some areas than others?
Movement is the main factor. Areas that are constantly active, such as the lips and around the mouth, work the filler harder and speed up its natural breakdown. Static areas like the cheekbones sit relatively still, so the product persists. The type of gel matters too. Thicker, more cross-linked hyaluronic acid resists breakdown, which is why it is chosen for deep structural support, while lighter gels used for fine lines or lip hydration fade sooner. Blood supply plays a part as well, since a richly vascular area clears the product more efficiently. Your body treats hyaluronic acid as something to gradually dissolve, and the local environment sets the pace.
What affects how quickly my body breaks down filler?
Individual biology counts for a great deal. Patients with faster metabolisms, and those who exercise intensely and regularly, often find their results fade a little sooner. Smoking, significant sun exposure and general skin ageing can all shorten the visible lifespan of a result. Age and hormonal changes influence how your tissues hold volume too. There is nothing you have done wrong if your filler seems to go quicker than a friend’s; we are all different. During your consultation I assess these factors honestly so the plan I suggest reflects your real life rather than an idealised average.
What happens as the filler wears off?
Hyaluronic acid fillers do not disappear overnight. They soften and shrink gradually, so the change is usually subtle and you rarely notice a sudden loss. The gel attracts water when first placed, which is partly why lips can look fuller in the early weeks; as that water balance settles and the product slowly degrades, volume eases back towards your natural baseline. Many patients choose a small top-up before the result has fully gone, which tends to maintain a smoother, more consistent appearance than waiting for it to vanish completely. You can read more about our approach to anti-ageing dermal fillers and the areas we treat.
Can I make my dermal fillers last longer?
To an extent, yes. Protecting your skin from sun with a daily SPF, staying well hydrated, not smoking and maintaining a stable weight all help your results hold their shape. Booking maintenance appointments before the filler has fully dissipated usually gives a more even, longer-lasting outcome than starting from scratch each time. Equally important is the skill of placement; correct depth, the right product for the area and a conservative, well-planned approach all contribute to results that both look natural and endure. I would always caution against chasing longevity by over-filling, as that rarely looks good and is not the aim of considered aesthetic work.
What does treatment cost and can I spread the payment?
Costs for dermal fillers in London vary by product and the number of areas treated, so I give a personalised quote at consultation rather than a one-size-fits-all figure. For eligible purchases up to £2,000, you may be able to spread the cost with Klarna at 0% interest, subject to status and eligibility. Klarna is the credit provider and the option appears at checkout for eligible products. I would rather you booked a consultation first, though, so we can agree the right treatment plan and give you an accurate price before you think about payment.
Frequently asked questions
Are dermal filler results permanent?
No, hyaluronic acid dermal fillers are temporary. They gradually break down over roughly six to eighteen months depending on the area and product. Your body dissolves the gel naturally over time. This temporary nature is actually an advantage, because it allows results to be adjusted or reversed rather than being fixed forever.
Can dermal fillers be dissolved if I do not like them?
Yes. One benefit of hyaluronic acid fillers is that a trained clinician can dissolve them using an enzyme injection if you are unhappy or if a correction is needed. This is a prescription treatment assessed case by case. We would discuss the risks, benefits and suitability with you fully at a consultation beforehand.
How often should I have top-up appointments?
It varies by area. Lips may benefit from a review around every six to nine months, while cheek or jaw contouring often lasts twelve months or longer. I usually suggest a maintenance appointment before the previous result has fully faded, as this tends to give a smoother, more consistent appearance over time.
Does filler last longer with each treatment?
Some patients feel results seem to hold slightly longer with repeat treatments, and there is a view that maintaining volume can reduce how much product is needed later. Evidence on this is limited and individual, so I would not promise it. Longevity still depends mainly on the area, product and your own biology.
Is there any downtime after dermal fillers?
Most people return to normal activities quickly. You may have some swelling, redness or bruising for a few days, particularly with lip treatment. I advise avoiding strenuous exercise, alcohol and excessive heat for around twenty-four to forty-eight hours. Full settling of the result typically takes about two weeks, so avoid judging it too early.
