"How long does filler last?" is one of the first questions people ask — and the honest answer is: it depends on the type, the area, the product quality, and the individual. A blanket "6 to 18 months" covers almost nothing. Here's a complete, area-by-area, type-by-type breakdown of filler longevity, and the factors that move the number in your specific case.
Longevity by filler type
The material is the starting point.
Hyaluronic acid (HA) filler: the most common type, and the most variable. HA is an enzyme your body already makes — it's gradually broken down by hyaluronidase, the body's natural enzyme, over months. Typical range: 6–18 months, varying significantly by area, product density, and individual metabolism. Reversible with injected hyaluronidase.
PLLA (poly-L-lactic acid): a biostimulator, not a volumizing filler. It works by stimulating your own collagen, so results build gradually and last considerably longer — commonly 2 years or more. Not reversible.
CaHA (calcium hydroxylapatite): a hybrid — adds immediate volume that lasts around 12–18 months, with some additional collagen stimulation as it's absorbed. Not reversible.
PMMA: semi-permanent to permanent. The tiny PMMA microspheres don't break down, so results last far longer — the collagen-containing carrier gel absorbs, but the beads remain.
Area matters just as much as type, because movement and blood supply affect how fast HA breaks down.
Area
Typical HA longevity
Why
Lips
6–9 months
Constant movement accelerates breakdown
Jawline
9–14 months
Frequent jaw movement
Nasolabial folds
9–12 months
Moderate movement
Cheeks
12–18 months
Less movement; deeper placement
Chin
12–18 months
Relatively low movement
Under-eye
12–18+ months
Minimal movement; slow breakdown
Temples
12–18 months
Deep, low-movement area
Lip filler lasts the shortest — the constant movement of talking, eating, and expression speeds up enzymatic breakdown. Under-eye and temple filler often lasts the longest for the opposite reason.
What actually makes filler wear off faster (or slower)
Beyond type and area, these factors move the needle:
Metabolism. People with faster metabolisms break down HA more quickly — it's the same reason some people feel caffeine wear off in an hour and others in four. You can't control this, but experienced injectors account for it when planning a maintenance schedule.
Product density and cross-linking. Higher-density, more cross-linked HA gels resist enzymatic breakdown longer. This is a manufacturing variable — a premium, tightly cross-linked product lasts longer than a cheap, loosely cross-linked one at the same injection site. It's one of the key differences between medical-grade and low-grade HA.
Injection depth. Filler placed in the right plane — deep for structural areas, superficial for fine lines — holds better. Misplaced filler breaks down faster and can migrate.
Exercise and heat. Very high levels of exercise and repeated heat exposure (saunas, hot yoga) may accelerate HA metabolism somewhat — the evidence is observational, but many injectors advise caution in the first weeks.
Touch-up timing. A small top-up before filler has fully dissipated tends to maintain results better than waiting until it's completely gone and starting from scratch each time.
The product quality factor — what buyers should know
Here's the part most longevity guides don't say: not all "HA filler" is the same, and the difference shows up directly in longevity. Medical-grade, pharmaceutical-purity HA that is tightly cross-linked with low residual BDDE holds structure longer than lower-grade alternatives. For clinics and brands, this is where sourcing decisions translate directly into patient outcomes and retention.
AOMA's HA dermal fillers use pharmaceutical-grade hyaluronic acid sourced at the highest purity grade, with a biphasic or monophasic gel structure engineered for consistent longevity across product grades — from fine-line soft gels (typically 9–12 months) to structural Derm Plus and Subskin grades (12–24 months for body areas). All produced under GMP with CE, ISO 13485, and SGS certification. For how to evaluate a manufacturer's quality claims, see the OEM sourcing guide.

FAQ
How long do lip fillers last? Typically 6–9 months for HA lip filler — shorter than most areas because the lips move constantly. Higher-density products and conservative volume tend to hold longer.
How long does cheek filler last? Usually 12–18 months. Cheeks are a lower-movement area and often use denser, deeper-placed gels.
Does filler last longer the more times you get it? Some injectors and patients report that repeat treatments maintain results longer over time, possibly because of cumulative collagen stimulation from the injection process. The evidence is observational.
Does exercise make filler wear off faster? Possibly — high metabolic activity and heat may speed HA breakdown slightly, especially early. Most injectors advise avoiding intense exercise and saunas for the first 24–48 hours post-treatment.
How do I make my filler last longer? Choose a high-quality product, use a skilled injector who places it at the correct depth, consider a small top-up before it fully dissipates, and follow your injector's aftercare advice on heat and exercise.
Is PLLA longer-lasting than HA filler? Yes — PLLA results typically last 2 years or more, versus 6–18 months for HA. The trade-off is that PLLA results build gradually and are not reversible.
