Most dermal fillers last between 6 months and 2 years, depending on the type of filler, where it’s injected, and your individual metabolism. Hyaluronic acid fillers, the most common type, typically last 6 to 12 months. Other formulations designed to stimulate your body’s own collagen production can last up to 2 years, and one FDA-approved option is permanent.
Duration by Filler Type
Not all fillers are made from the same material, and the material is the single biggest factor in how long your results stick around.
Hyaluronic acid (HA) fillers are the most widely used. Brands like Juvederm and Restylane fall into this category. The FDA describes their effects as lasting approximately 6 to 12 months, but specific products within these lines vary. Juvederm Voluma XC, designed for the cheeks, can last up to 2 years in that area and up to 1 year in the chin. Juvederm Ultra XC and Restylane Kysse, both popular for lips, last up to 1 year. The differences come down to how the hyaluronic acid molecules are cross-linked during manufacturing. Juvederm’s Vycross technology, for instance, blends different molecular weights of hyaluronic acid to create a gel that resists breakdown longer than earlier formulations.
Calcium hydroxylapatite fillers (sold as Radiesse) use a mineral naturally found in human bones and teeth, suspended in a gel. The gel provides immediate volume, then the mineral particles stimulate your body to build new collagen over the following months. Results last approximately 12 to 18 months.
Poly-L-lactic acid fillers (sold as Sculptra) work differently from most fillers. Rather than adding volume directly, the injected material triggers a gradual collagen-building response. Results develop slowly over 6 to 12 weeks and last up to 2 years. Sculptra is typically given as a series of injections over several months rather than a single session.
PMMA fillers (sold as Bellafill) are the only FDA-approved permanent filler. The product contains tiny plastic microspheres that the body cannot absorb. Because the material is non-absorbable, implantation is permanent and cannot be reversed without physical removal. That permanence cuts both ways: if complications develop, such as lumps, nodules, or granulomas, they can appear months or even years after injection and are much harder to correct than issues with temporary fillers.
How Location Affects Longevity
The same filler can last dramatically different amounts of time depending on where it’s placed in your face. The key variable is movement. Areas that move constantly, like your lips and the skin around your mouth, break down filler faster because repetitive muscle activity degrades the material. Areas with less movement retain filler much longer.
Lips: Filler here tends to fade the fastest. With touch-ups, lip augmentation results can be maintained for 18 months or more, but many practitioners recommend touch-ups every 6 to 9 months to keep lips looking consistent.
Cheeks: Using a volumizing HA filler like Juvederm Voluma, cheek results can last up to 24 months. A touch-up at the 12-month mark helps maintain and extend the effect. General maintenance intervals for cheek and chin fillers fall in the 9 to 18 month range.
Under the eyes: The tear trough area is one of the least dynamic parts of the face, and HA filler here can last several years. Touch-ups are generally recommended every 24 months, though some practitioners suggest check-ins at 9 to 12 months.
What Speeds Up Filler Breakdown
Your body is constantly working to metabolize and absorb the injected material. Several factors influence how quickly that happens.
A faster metabolism generally means shorter filler life. People who exercise intensely and frequently often notice their results fading sooner. High-intensity workouts increase metabolic activity throughout the body, which can accelerate the breakdown of hyaluronic acid in particular. This doesn’t mean you should stop exercising to preserve your filler, but it’s worth knowing that a very active lifestyle may put you on the shorter end of expected duration.
Heat exposure also plays a role. Saunas, hot yoga, and prolonged sun exposure dilate blood vessels and increase circulation to the face, which can contribute to faster product breakdown. In the first 24 to 48 hours after injection, heat and vigorous movement carry an additional risk: the gel may shift before it has fully settled, integrating unevenly with the surrounding tissue.
Typical Maintenance Schedules
Most people get better long-term results by scheduling touch-ups before their filler has fully dissolved, rather than waiting for it to wear off completely and starting over. Topping off existing volume requires less product and tends to look more natural than rebuilding from scratch each time.
As a general guide, lip fillers are typically maintained every 6 to 9 months, cheek and chin fillers every 9 to 18 months, and under-eye fillers every 9 to 12 months. The right interval for you depends on the specific product used, how your body metabolizes it, and your personal preference for how “full” you want the results to look.
Signs it’s time for a touch-up include the gradual return of lines or wrinkles, noticeable loss of volume or definition in the treated area, and results that simply feel less fresh. These are signs of normal, expected filler breakdown.
Normal Fading vs. Filler Migration
As filler dissolves naturally, the treated area gradually returns to its pre-injection appearance. This is a slow, even process. Your body breaks down and absorbs the material over months, and your face simply reverts to how it looked before. If you choose not to get a touch-up, no further treatment is needed.
Migration is different. It happens when filler shifts away from the injection site, creating fullness or lumps in areas that were never treated. The result is often an uneven, puffy look, particularly noticeable above the lip border or around the edges of the original injection area. If you notice new volume or bumps in places that didn’t receive filler, that’s migration rather than natural breakdown, and it’s worth having evaluated by the provider who did your injections.
The Case Against Permanent Fillers
Permanent fillers might sound appealing, but they carry risks that temporary options don’t. Bellafill, the only FDA-approved permanent filler, has documented post-market complications including lumps, nodules, granulomas, and persistent swelling that can appear anywhere from immediately after injection to three and a half years later. In clinical trials, about 4.6% of patients developed lumpiness at the injection site that persisted beyond one month, and 3.5% experienced prolonged swelling or redness.
More seriously, a case of permanent blindness was reported after Bellafill injection near the eye. This risk of vascular complications exists with all injectable fillers, but with temporary products, the material eventually dissolves. With PMMA microspheres, any complication is as permanent as the filler itself unless surgically removed. For most people, the predictable maintenance schedule of temporary fillers is a worthwhile tradeoff for the ability to adjust, dissolve, or simply stop treatment over time.
