Lips, cheeks, under-eyes and jawline: how long hyaluronic acid fillers last in each area, what shortens or extends results, and how to keep them natural.
Most hyaluronic acid fillers last somewhere between six months and two years. That is a wide range, and the honest answer depends on where the filler is placed, which product is used and how your body breaks it down. This guide explains what to expect area by area, what makes filler last longer, and how to keep results looking natural over time.
At the clinic: Dr. Fehmida uses fillers to restore lost volume with a light hand. See our dermal fillers page or our page on volume loss.
How fillers work
Most modern fillers are made of hyaluronic acid, a sugar that occurs naturally in the skin and holds water. The filler is a gel that replaces lost volume or adds structure, and the body slowly breaks it down. Firmer gels are made for deeper areas such as the cheeks and jawline, and softer gels for the lips and fine areas. The type of gel is one of the biggest factors in how long a result lasts.
How long fillers last, by area
| Area | Typical duration | Why |
|---|---|---|
| Lips | 6 to 12 months | Constant movement and a soft gel |
| Lines from nose to mouth | 9 to 12 months | A mobile area of the face |
| Under the eyes | 12 to 18 months, often longer | Very little movement |
| Cheeks | 12 to 18 months | A firmer gel placed deep |
| Chin and jawline | 12 to 18 months | A firm gel placed close to bone |
| Temples | 12 to 18 months | Little movement |
Sculptra works differently. It is not a filler but a collagen stimulator, and the collagen it builds can last around two years.
What makes fillers last longer or shorter
- The product. Denser, more cross-linked gels last longer than soft ones.
- Movement. Areas that move a lot, such as the lips, break filler down faster.
- Metabolism. People who exercise intensely or have a fast metabolism often find results fade sooner.
- Sun and smoking. Both speed up the breakdown of hyaluronic acid and collagen.
- Technique. Filler placed in the right layer, in the right amount, holds its shape better.
Filler often lasts longer than you can see
Studies using scans have found hyaluronic acid filler in the tissue years after it was injected, long after the visible result has softened. This is why top-ups should be smaller than the first treatment. Adding the full amount every time is how faces end up looking overfilled, and it is the main reason we plan maintenance carefully rather than on a fixed schedule.
Keeping results natural
Most patients have a small top-up when they first notice the result softening, rather than waiting until it has gone completely. This uses less product and keeps the change subtle. Anti-wrinkle injections, which last three to four months, are often combined with fillers because they do a different job. Our guide to Botox vs fillers explains the difference.
For the under-eye area, filler is not always the best answer. When the main problem is thin or dark skin rather than a hollow, polynucleotides often give a better result. See our page on tired eyes.
Safety
Hyaluronic acid filler can be dissolved with an enzyme called hyaluronidase if the result is not right or if there is a complication. Filler should only be injected by a medical professional who knows facial anatomy and can manage problems if they arise. Ask which product is being used and whether it can be dissolved before you agree to treatment.
Frequently asked questions
Do fillers last longer the second time?
Often, yes. Some filler usually remains in the tissue, and treatment can stimulate a little collagen, so many people need less product and less often over time.
What happens when filler wears off?
The area gradually returns to how it looked before. Filler does not stretch the skin or make it worse when it fades.
How long do lip fillers last?
Usually six to twelve months. Read more in our guide to lip fillers.
Can filler be removed?
Hyaluronic acid filler can be dissolved with hyaluronidase, usually with a visible change within a day or two.
How often should I have a top-up?
There is no fixed rule. Most people need a small top-up every 9 to 18 months, depending on the area and how their face changes.
