Most injectable fillers last between 6 and 24 months, depending on the type of filler, where it’s placed, and how quickly your body breaks it down. Hyaluronic acid fillers, the most common category, typically last 6 to 12 months. Other formulations designed to stimulate your body’s own collagen can last two years or longer, and one FDA-approved option is technically permanent.
Hyaluronic Acid Fillers: 6 to 12 Months
Hyaluronic acid fillers, including brands like Juvederm, Restylane, and Belotero, are by far the most widely used. They work by adding volume directly under the skin using a gel made from hyaluronic acid, a sugar molecule your body naturally produces. These fillers are classified as medium-term, designed to last between 3 and 12 months, though many people get closer to the 6 to 12 month range in practice.
One major advantage of hyaluronic acid fillers is that they’re reversible. An enzyme called hyaluronidase can dissolve them if something goes wrong or you’re unhappy with the results. It works almost immediately in many cases, though denser, more heavily cross-linked products can take up to 48 hours to fully break down. Final results from a dissolution treatment may take up to two weeks, and the procedure sometimes needs to be repeated.
Most practitioners recommend touch-up injections every 6 to 9 months to maintain full results, though some patients stretch this to 9 to 12 months depending on how gradually the filler fades.
Calcium Hydroxylapatite: Up to 30 Months
Radiesse, made from calcium hydroxylapatite, lasts significantly longer than hyaluronic acid fillers. It can persist for up to 30 months. Rather than simply filling space, Radiesse works through a different mechanism: the tiny ceramic microspheres in the gel physically interact with your skin cells, triggering them to produce new collagen, elastin, and other structural proteins. This means the filler provides immediate volume, and then your body gradually builds its own support structure around the material as it biodegrades.
The trade-off is that Radiesse cannot be dissolved with an enzyme the way hyaluronic acid fillers can. If you don’t like the result, you’re waiting for your body to absorb it naturally.
Sculptra: Two Years or More
Sculptra takes the collagen-stimulating approach even further. Made from poly-L-lactic acid, it doesn’t add much immediate volume. Instead, it works gradually over weeks and months as your body responds to the injected material by producing new collagen. Results can last more than two years, but Sculptra typically requires a series of treatment sessions spaced weeks apart to build up the effect.
Because the results come from your own collagen rather than the filler material itself, the fade is very gradual. Most people return for a new series of injections every few years to maintain results.
Bellafill: Permanent but Not Reversible
Bellafill is the only FDA-approved filler that’s truly permanent. It contains tiny plastic microspheres (polymethylmethacrylate, or PMMA) suspended in a collagen gel. Your body absorbs the gel over time, but the microspheres stay in place indefinitely. According to the FDA labeling, implantation is permanent and cannot be reversed without physical removal.
That permanence comes with unique risks. Post-marketing reports include lumps, bumps, nodules, granulomas (inflammatory tissue reactions), and swelling, with some adverse events appearing as late as three and a half years after injection. The FDA notes that long-term safety beyond one year has not been fully established. A skin test is required before treatment because the product contains bovine collagen, which can trigger allergic reactions.
Where You Get Filler Changes How Long It Lasts
The same filler can behave very differently depending on where it’s placed in your face. Areas that move a lot break down filler faster. Lip fillers typically last 6 to 12 months, with many people noticing a reduction around the 6-month mark. The constant motion of talking, eating, and making expressions accelerates how quickly the filler is metabolized.
Cheek and jawline fillers tend to last 12 to 18 months or longer. These areas experience less repetitive movement, and the filler is usually placed deeper in the tissue, which helps it persist. If you’re budgeting for maintenance, expect to return more frequently for lip treatments than for cheek or jawline work.
Why Fillers Fade Faster in Some People
You’ve probably heard that people with “fast metabolisms” burn through filler more quickly. There’s limited direct research on filler degradation and metabolism, but a closely related clinical trial offers a useful clue. Researchers studying Botox (which isn’t a filler, but shares the same patient population) found that people with high levels of physical activity saw their results fade significantly faster than those with low activity levels. The high-activity group showed muscle recovery as early as two months after treatment, while the low-activity group maintained results throughout the study.
The researchers hypothesized that exercise-related increases in growth factors like IGF-1 may speed up how the body processes these cosmetic injectables. While this study looked at Botox specifically, the underlying biology suggests that highly active people may metabolize fillers faster as well. It’s worth factoring in if you’re an intense exerciser trying to predict how often you’ll need touch-ups.
Age also plays a role, though in a less intuitive way. Younger skin with robust blood flow may actually process filler faster, while older skin with less circulation can hold onto filler longer. Individual variation is significant enough that two people getting the exact same product in the exact same spot can have noticeably different timelines.
Typical Maintenance Schedules by Filler Type
- Hyaluronic acid (Juvederm, Restylane, Belotero): Touch-ups every 6 to 12 months, depending on placement and how gradually you’re comfortable letting it fade.
- Calcium hydroxylapatite (Radiesse): Repeat treatments roughly every 12 to 18 months for most people, though results can last up to 30 months in some cases.
- Poly-L-lactic acid (Sculptra): An initial series of 2 to 3 sessions, then a new series every 2 to 3 years.
- PMMA (Bellafill): No scheduled maintenance needed since the microspheres are permanent, though minor touch-ups may be desired over time as your face naturally changes with aging.
If you’re new to fillers, most practitioners start with hyaluronic acid. It’s the most forgiving option: predictable, reversible, and widely available. You can always move to a longer-lasting product once you know what look you’re going for and how your body responds.
