How Long Does Lip Filler Last?

FDA groups fillers by material and publishes a general duration estimate for each one.

For hyaluronic acid — the material in the Juvéderm collection and in Restylane Kysse — that estimate is approximately 6 to 12 months.

It is a material-level estimate for hyaluronic acid fillers in general, not a lip-only number.

The figures published for the lip products themselves sit at or under one year.

Allergan says results with Juvéderm Volbella XC and Juvéderm Ultra XC in the lips can last up to 1 year "with optimal treatment" — a maker's stated maximum, not an average.

Teoxane and Revance, the companies behind the RHA collection, say RHA fillers last up to a year in the lips, and up to 15 months in dynamic wrinkles and folds, which is not a lip area.

The most detailed public lip data we found is a trial, not a marketing page.

In the Restylane Kysse pivotal trial, a blinded evaluator rated 60% of treated subjects (101 of 169) as still lip-fullness responders at week 48 — meaning at least a 1-point improvement on the Medicis Lip Fullness Scale, just short of the one-year mark.

In plain terms: at that week-48 visit, a majority of the studied subjects still showed measurable correction, and the rest did not.

Duration figures are published per product and per area, so what matters here is the specific filler.

Here is what is published for the lip products, and who published it.

• Juvéderm Volbella XC and Ultra XC (Allergan): up to 1 year in the lips with optimal treatment — a maker claim.
• Restylane Kysse (Galderma): 60% of trial subjects still lip-fullness responders at week 48 (101 of 169) — trial data, not a maker maximum.
• RHA fillers (Teoxane/Revance): up to a year in the lips and lipstick lines, and up to 15 months in dynamic wrinkles and folds — a maker claim.

Two cautions when reading these numbers.

First, "up to" figures are maximums under a maker's own phrase "optimal treatment", and a trial percentage describes the group studied, not the result any one person will get.

Second, longer numbers you may have seen belong to other areas: Allergan says Voluma XC lasts up to 2 years in the cheeks and Vollure XC up to 18 months in the smile lines, and neither product — nor Ultra Plus XC or RHA 2 — is approved for the lips at all.

Other products are approved for the lips — Restylane Silk (2014) and Revanesse Lips+ (2020) among them — but we found no duration figure for them in the labels and trials we checked, so they are not in the list above.

RHA 3 is the only RHA product with a lip indication, approved on 2023-10-27 for the vermilion body, vermilion border and oral commissures in adults 22 or older.

The fading is the design.

FDA groups filler materials into absorbable (temporary) ones — hyaluronic acid, calcium hydroxylapatite and poly-L-lactic acid — and one non-absorbable (permanent) material, PMMA microspheres in bovine collagen.

FDA says it has approved only one product made from a material the body does not absorb.

That product is Bellafill, originally sold as ArteFill and renamed SANAE in 2026 with FDA's approval: PMMA microspheres in bovine collagen, approved in 2006 for nasolabial folds (smile lines) and in 2014 for certain atrophic cheek acne scars.

Its approved indications do not include the lips, so no permanent filler is approved for the lips.

The lip fillers with published material details in this guide — the Juvéderm gels and Restylane Kysse — are hyaluronic acid, one of FDA's absorbable materials.

How the fade works, in the Kysse label's own words: biodegradation varies by individual and treatment area, and "product remnants may remain in the tissue even when the clinical effect has returned to baseline." In other words, the look can fade before the filler is entirely gone.

One small study underlines the point.

An MRI study of 33 patients found mid-face hyaluronic acid filler still detectable in all of them at least 2 years after injection, with some filler visible 8 to 15 years later.

That study looked at the mid-face, not the lips, and 33 people is a small group — but it shows HA filler can linger in tissue long after results fade.

If waiting is not appealing, hyaluronidase injections can dissolve hyaluronic acid filler — and only HA filler.

Cleveland Clinic says dissolving usually takes one to two visits, with full results in up to two weeks, and that providers ask about a bee-sting allergy before using it.

FDA cautions that removing filler can require injections, surgery or other interventions with their own risks, and may be difficult or impossible — especially for permanent fillers or fillers not made of hyaluronic acid.

Allergan's own information sheet states that the effectiveness of removal of any dermal filler has not been studied.

Our filler dissolving guide covers the process in detail.

The honest answer starts with the label's own words: biodegradation varies by individual and by treatment area.

Cleveland Clinic points to age and metabolism as reasons lip filler duration varies.

Neither the label's biodegradation line nor the clinic page puts a number on how much any one factor matters, and we could not find a study that measures it.

Product choice matters too.

FDA describes hyaluronic acid as a sugar naturally present in skin and cartilage, and says filler HA is often chemically crosslinked to last longer.

Each duration figure is tied to its own product and area — a maker's figure for one product and one area is not another product's.

You may have seen claims that specific habits — exercise, sun exposure, even kissing — melt lip filler faster.

We found no controlled trial measuring any of them.

The aftercare rules in Juvéderm's labeling (no makeup for 12 hours, and minimizing strenuous exercise, extensive sun or heat exposure, and alcohol for the first 24 hours) exist because those things may cause temporary redness, swelling and itching — the label ties them to side effects, not to how long results last.

No label or trial we found sets a refill schedule for the lips, so when to book is a decision to make with a licensed provider based on how your lips look and feel to you.

What the record does show is that top-ups were part of how these products were studied: in the Restylane Kysse trial, the median volume for initial treatment plus touch-up was 2.50 mL across all areas — a median of 0.90 mL in the upper lip and 0.80 mL in the lower lip — and subjects who were retreated received a median of 1.30 mL.

Volume still has a ceiling.

The Kysse label sets a recommended maximum of 6 mL per patient per treatment, with no more than 3 mL of that in the lips.

Cleveland Clinic says about 1 mL of filler goes into the lips on average, and points to a follow-up visit about two weeks after treatment to review the final result.

If your filler fades faster than you expected, a touch-up is not the only option — dissolving and starting again with a different product is a conversation to have with the same licensed provider.
