Marionette lines are the creases that run straight down from the corners of your mouth toward your chin, named for the hinged jaw on a puppet. They make the mouth look like it is frowning even when your face is at rest, and that downturned look is one of the most common reasons people walk into a med spa asking to "fix the sad face." This guide walks through which treatments actually move the needle on marionette lines, how strong the evidence is for each, and where the marketing gets ahead of the science.
What Marionette Lines Actually Are
A marionette line is not one problem. It is usually three problems stacked on top of each other, and that is the single most important thing to understand before you spend money.
First, there is volume loss. As you age, the fat pads in the lower face shrink and shift, and the bone underneath the mouth recedes. That creates a hollow and a shadow at the corner of the mouth. Second, there is muscle pull. A small paired muscle called the depressor anguli oris (DAO) runs from the corner of the mouth down to the jaw, and its only job is to pull the mouth corner down. Over decades of frowning, talking, and chewing, that muscle gets relatively stronger and the upward-lifting muscles get weaker, so the corner sits lower at rest. Third, there is skin change. Collagen and elastin drop with age and sun damage, so the skin creases and folds more easily and holds the crease longer.
Most marionette lines are some mix of all three. That is why no single treatment is a magic fix, and why the best plans usually combine two or three approaches. A practitioner who only offers one tool will tend to recommend that tool for everyone, which is worth keeping in mind.
There is a quick self-test that tells you a lot. Look in a mirror with your face completely relaxed and note how deep the line and how downturned the corner look at rest. Then gently stretch the skin flat with two fingers. If the line nearly disappears when flattened, you are dealing mostly with a volume-and-shadow problem, and filler is likely to help. If the corner still droops downward even with the skin stretched, muscle pull is a bigger driver, and toxin belongs in the plan. If the surrounding skin looks crepey and finely creased regardless, skin quality is part of the picture, which points toward retinoids and possibly an energy device. None of this replaces an in-person assessment, but it helps you walk in with realistic expectations instead of chasing whatever the clinic is promoting that month.
The Treatments, Graded by Evidence
Here is the honest landscape. The grades below reflect how much good clinical evidence exists specifically for the lower face and mouth corners, not just general marketing claims.
| Treatment | Targets | Evidence grade | Typical duration | Rough cost (US, 2026) |
|---|---|---|---|---|
| Hyaluronic acid (HA) filler | Volume loss, shadow | Strong | 6–18 months | $700–$1,200 per syringe |
| DAO botulinum toxin (Botox/Dysport) | Muscle downturn | Moderate | 3–4 months | $150–$400 per session |
| Biostimulators (Sculptra, Radiesse) | Volume, collagen, laxity | Moderate | 1–2 years | $800–$1,000+ per vial |
| Prescription tretinoin (retinoid) | Skin quality, fine lines | Strong (for photoaging broadly) | Ongoing daily use | $20–$70/month |
| Energy devices (RF, RF microneedling, lasers) | Skin laxity, texture | Moderate / mixed | Varies; needs a series | $300–$1,500 per session |
| PDO thread lift | Mechanical lift | Weak | 6–12 months | $1,000–$2,500 |
The sections below explain the mechanism behind each, what the studies show, and where the evidence is genuinely shaky.
Hyaluronic Acid Filler — the workhorse
How it works: Marionette lines are largely a shadow cast by a hollow. Hyaluronic acid is a sugar molecule your body already makes that holds water and adds volume. Inject it into the crease and the adjacent corner of the mouth, and you flatten the trough so light no longer pools there. Some injectors also build structure in the chin and jawline so the marionette area is supported from below rather than just filled head-on.
The evidence: This is the best-studied option for the actual marionette area. In a 12-month prospective study of the HA filler VYC-17.5L (a Juvederm product) injected specifically into marionette lines, 98.8% of participants were rated "improved" or "much improved" by the investigator one month after treatment, and patient satisfaction scores rose significantly from baseline (PMID 39600229). That is a strong, treatment-specific result.
Read the fine print, though. In that same study, the share of people still rated "improved" fell to roughly 50% by month 12 (PMID 39600229). So "lasts up to 18 months" is a best case, not a promise. For many people, real-world results in this mobile part of the face fade closer to the 9–12 month mark. The broader filler literature for the lower face is consistent and you can scan it through a PubMed search for marionette line filler studies.
Who it's for: People whose main problem is a visible hollow and shadow. If you press the skin flat with a finger and the line largely disappears, filler will likely help a lot.
DAO Botulinum Toxin — for the downturn
How it works: The depressor anguli oris pulls the corner of the mouth down. A few units of botulinum toxin (Botox, Dysport, Xeomin) placed into the DAO relax that downward pull, so the opposing lifting muscles can let the corner sit a little higher and more neutral. It does not fill the crease. It changes the resting angle of the mouth.
The evidence: There is solid anatomical and clinical work here, though the studies are smaller than the big filler trials. A clinical study on elevating the corner of the mouth with botulinum toxin type A reported visible elevation of the mouth angle after injecting the depressor muscles (PMID 21430826). A later retrospective and anatomical study mapped the safest place to inject the DAO and confirmed good clinical outcomes when toxin is placed in the upper portion of the muscle to avoid spreading into the nearby muscle that lowers the lip, which sits just below and can cause an uneven smile if treated by mistake (PMID 35139057). You can browse the body of evidence through a PubMed search on DAO botulinum toxin.
Where it gets honest: DAO toxin is a precision treatment. The muscle is small, it sits close to muscles that control your smile, and over-dosing or poor placement can produce an uneven or stiff smile, drooling, or trouble with certain words. This is one of the more technique-dependent injections in the face, so the injector matters more here than almost anywhere else. And toxin does nothing for the hollow, which is why it is so often paired with filler.
Who it's for: People whose corners turn down at rest, especially younger faces where the skin and volume are still good but the mouth just looks unhappy.
Biostimulators — Sculptra and Radiesse
How it works: These are not classic fillers. Sculptra (poly-L-lactic acid) and Radiesse (calcium hydroxylapatite) prompt your own body to build collagen over weeks to months. Radiesse also gives some immediate volume; Sculptra works almost entirely through the gradual collagen response. The idea is to rebuild the structural support of the lower face and jawline so the whole marionette region is lifted from beneath, rather than just plugging the crease.
The evidence: Reasonable but more general. Both products are FDA-approved for correcting moderate to severe facial wrinkles and folds, and there is a growing body of work on hyperdilute and multilayer techniques in the lower face showing reductions in jowl and marionette depth. The catch is that much of the marionette-specific data comes from open-label case series and technique papers rather than large randomized trials, so the evidence grade is moderate rather than strong. Results also come in slowly, usually requiring two or three sessions spaced a month or more apart, and you will not see the final outcome for several months.
Who it's for: People with broader lower-face laxity and volume loss who want a more structural, longer-lasting approach and are patient enough to wait for collagen to build.
Tretinoin and Skincare — the quiet base layer
How it works: Tretinoin is a prescription retinoid. It increases skin cell turnover, blocks the enzymes that break collagen down, and nudges the skin to make new type I collagen. It will not erase a deep marionette fold, but it improves skin quality, texture, and fine lines, which makes everything else look better and helps maintain results.
The evidence: This is genuinely strong, just not marionette-specific. A systematic review of randomized controlled trials found topical tretinoin reliably improved the clinical signs of photoaging, including wrinkling, with benefits showing as early as one month and persisting with continued use (PMID 35620028). The honest framing: tretinoin is the best-proven at-home tool for skin aging in general, but no one should expect a cream to flatten an established mouth-corner fold. Think of it as the foundation, not the fix.
Who it's for: Almost everyone, as a long-term base. It is cheap, well-studied, and supports the more expensive treatments.
Energy Devices — RF, RF microneedling, and lasers
How it works: Radiofrequency (RF), RF microneedling, and fractional lasers heat the deeper skin to trigger collagen remodeling and tighten lax tissue. For marionette lines, the goal is to firm the skin so it creases less and holds folds less.
The evidence: Mixed, and this is where honesty matters most. There is decent evidence that these devices improve skin laxity and perioral and periorbital wrinkles, and RF microneedling in particular has shown measurable improvement in hard-to-treat wrinkles. But the effect sizes are modest. One review noted that a single session of fractional RF microneedling achieved only about a third of the laxity improvement you would get from a surgical facelift, meaning multiple sessions are needed and the result is still partial. For a deep, shadow-driven marionette line, energy alone usually underdelivers. It is a supporting player that helps skin quality and mild laxity, not a stand-alone answer for a real fold.
Who it's for: People with mild laxity and decent volume who want to improve skin texture and firmness, ideally as part of a combination plan.
PDO Thread Lifts — proceed with skepticism
How it works: Dissolvable polydioxanone (PDO) threads are passed under the skin to mechanically lift sagging tissue and, in theory, stimulate some collagen along the thread.
The evidence: This is the weakest of the commonly offered options. Systematic reviews describe the field as scarcely studied, with short follow-up and a focus on materials and complications rather than durable outcomes. The lift tends to be modest and short-lived, with threads dissolving within roughly 6 to 12 months, and there are real reports of irregularities, scarring under the skin, and results that can make later procedures harder. Given the cost and the thin evidence, threads are hard to recommend as a first-line treatment for marionette lines specifically.
Who it's for: A narrow group with mild sagging who understand the limits and accept that the evidence is weak. Most people get more reliable results from filler plus toxin for the same or less money.
How the Best Plans Combine Treatments
Because marionette lines are usually a stack of problems, the most effective plans usually stack treatments. A common, evidence-aligned approach looks like this.
| Your main issue | First-line plan | Add-on if needed |
|---|---|---|
| Deep crease, finger-flattens the line | HA filler in the line and chin support | DAO toxin if corners also droop |
| Corners turn down at rest, good volume | DAO botulinum toxin | A small amount of filler |
| Broad lower-face laxity and volume loss | Biostimulator series (Sculptra/Radiesse) | Energy device for skin quality |
| Mostly skin texture and fine lines | Daily tretinoin | Energy device or light filler |
A practical sequence many injectors use: relax the DAO with a few units of toxin first, wait about two weeks to see where the mouth sits, then fill the residual hollow with HA. Treating the muscle first means you do not waste filler fighting a downward pull, and you often need less filler overall. Tretinoin runs in the background the whole time.
There is also a structural logic worth understanding. The marionette region does not sit in isolation. It is held up, or not, by the chin and jawline beneath it and the cheek above it. When the midface deflates and the chin recedes, the soft tissue of the lower face slides forward and down, deepening the marionette fold from the top. That is why experienced injectors often treat the chin and jawline, or restore a little cheek support, rather than only chasing the line itself. Filling the line head-on without addressing the support underneath can look unnatural and tends to fade faster, because you are fighting gravity instead of working with the face's architecture. This is the single biggest reason results vary so much between injectors using the same products.
Costs, Sessions, and Realistic Timelines
Money and time expectations are where a lot of disappointment comes from, so it helps to be concrete. Filler is usually the fastest path to a visible change: one appointment, immediate results, and a return visit in 9 to 12 months for most people. Plan for one to two syringes for a typical marionette-plus-chin-support treatment, which puts a realistic first-year cost in the rough $800 to $2,000 range depending on your city and how much structural support you need.
Toxin is cheaper per visit but more frequent. DAO treatment runs a few units per side and needs repeating every three to four months to maintain, so the annual cost adds up even though each session is modest. Biostimulators flip the equation: higher upfront cost and a series of two or three sessions, but results that can hold for one to two years, which can make them cheaper over time for the right candidate. Energy devices almost always require a series of three to six sessions for a meaningful result, and the per-session price hides the true cost of the full course.
Timelines matter too. Filler is instant but settles over about two weeks as swelling resolves. Toxin takes 5 to 14 days to kick in fully. Biostimulators are the slow burn, with the real result emerging over two to three months as collagen builds. Anyone promising a permanent fix in a single visit for a deep marionette fold is overselling.
Safety and Realistic Risk
The lower face is rich in blood vessels, including branches of the facial artery, which makes filler placement near the mouth corners a higher-skill, higher-stakes area. The most serious filler risk is vascular occlusion, where filler is injected into or compresses a blood vessel, cutting off blood supply. This can cause tissue death (necrosis) and, in rare cases when filler travels back toward the eye, vision loss. The FDA lists these among the known risks of soft-tissue fillers, alongside far more common issues like bruising, swelling, lumps, and asymmetry (see the FDA dermal fillers page). A systematic review of filler safety confirms that while serious vascular events are uncommon, they cluster in the central and lower face, which includes the marionette and perioral region (filler safety review, PMC11766492).
Two practical takeaways. First, choose your injector on skill, not price. A board-certified dermatologist, plastic surgeon, or an experienced injector who keeps hyaluronidase (the enzyme that dissolves HA filler) on hand for emergencies is worth the premium. Second, hyaluronic acid fillers have a real safety advantage here because they can be dissolved if something goes wrong, which is one reason many injectors prefer HA over permanent fillers around the mouth.
For toxin, the main risks are temporary: an uneven smile, mouth weakness, or drooling if the toxin spreads beyond the DAO. These resolve as the toxin wears off over a few months, but they are unpleasant, which again argues for an experienced injector.
Who Each Treatment Is Best For
If you are in your 30s or 40s with good skin and just a downturned look at rest, DAO toxin alone may be enough, and it is the cheapest entry point. If you have a defined crease and a hollow, HA filler is the most reliable single treatment, often paired with a touch of toxin. If your whole lower face has softened and you want a longer, more structural change, a biostimulator series fits better, though you trade speed for durability. And nearly everyone benefits from a nightly retinoid as the long-term base. If a clinic pushes threads as the answer for a deep marionette fold, ask why filler or toxin is not the first move.

Frequently Asked Questions
Can Botox alone get rid of marionette lines?
Sometimes, but only for the right person. If your marionette area is mostly a downturned mouth corner at rest with little volume loss, relaxing the depressor anguli oris muscle with botulinum toxin can lift the corner and soften the look. If there is a real crease and hollow, toxin will not fill it, and you will likely need filler too. Toxin also wears off in 3–4 months, so it is a maintenance treatment, not a one-time fix.
How long do fillers last in marionette lines?
In a 12-month study of an HA filler placed in marionette lines, nearly all patients were improved at one month, but only about half were still rated improved at 12 months (PMID 39600229). The mouth is a high-movement zone, so filler tends to break down faster here than in stiller areas. A realistic expectation is 9–12 months for many people, with up to 18 months in best cases.
Are marionette line treatments permanent?
No. Hyaluronic acid filler and botulinum toxin are both temporary and need repeating. Biostimulators like Sculptra and Radiesse last longer, often one to two years, because they build your own collagen, but even those fade. Tretinoin only works while you keep using it. The only truly long-term option for severe lower-face aging is surgery, which is a different conversation with different risks.
What is the safest treatment for marionette lines?
There is no risk-free option, but hyaluronic acid filler has one clear safety advantage: it can be dissolved with hyaluronidase if there is a problem, including the rare but serious vascular complications the FDA describes for all fillers. Botulinum toxin side effects are temporary and resolve as it wears off. The biggest single safety factor for any of these is the skill of your injector, so prioritize credentials over the lowest price.
Do at-home creams or devices work on marionette lines?
A prescription retinoid like tretinoin genuinely improves skin quality and fine lines, with strong randomized-trial support for photoaging overall (PMID 35620028). But no cream or at-home gadget will flatten an established marionette fold, because that fold is driven by lost volume and muscle pull beneath the skin, not surface texture. Use skincare as your maintenance base and set in-office treatments as the actual fix for the fold.
