Marionette Lines Botox in Toronto: What to Know Before Softening the Lines Around Your Mouth
Botox softens marionette lines by relaxing the depressor anguli oris (DAO), a small muscle that pulls the corners of the mouth downward. Less downward pull means the folds that run from the mouth toward the chin can look softer, and the corners of the mouth can rest in a more neutral position. Botox works best on lines caused by muscle movement, and it does not replace lost volume, so deeper folds are often discussed alongside hyaluronic acid filler instead.
That short answer leaves out most of what people actually want to know. Are these lines a muscle problem or a volume problem? Is the treatment even approved for this area? How many visits does it take, and what does a conservative plan look like? I think the honest answer to most of those is “it depends on your face,” which is not very satisfying, so this guide tries to give you enough detail to have a useful conversation at a consultation.
At Rejuvenation Med Clinic, our marionette lines Botox treatment sits inside a wider range of cosmetic injectable services in Toronto. Some people arrive asking for Botox and leave with a plan that also mentions filler, and some arrive asking for filler and learn that a small amount of Botox was the missing piece. Either outcome is completely normal.

What marionette lines are, and why they form
Marionette lines are the vertical creases that start at the corners of the mouth and run down toward the chin, a little like the hinge lines on a puppet’s jaw, which is where the name comes from. They are a very common part of how faces change over time, and they are not a sign that anything is wrong. Some people notice them in their thirties, others not until their fifties or later.
The usual contributors
There is rarely a single cause. Cleveland Clinic describes marionette lines as the result of natural loss of collagen and elastin, genetics, sun exposure, smoking, stress and repetitive lip pursing, and most faces have a combination. Bone and fat pads also shift slowly with age, which means the lower face can lose support even when the skin itself looks healthy.
Why the mouth corners matter so much
The corners of your mouth are anchored by several muscles that pull in different directions. Some lift the corners when you smile. The DAO pulls them down. If the downward pull is relatively strong, or the lifting muscles have less to work with, the resting expression can drift toward looking tired or stern even when you feel perfectly cheerful. Many people describe that mismatch first, before they ever mention the lines themselves.
Marionette lines are not the same as nasolabial folds
Nasolabial folds, often called smile lines, run from the sides of the nose toward the corners of the mouth. Marionette lines start at the mouth corners and continue downward. They often show up together and they influence each other, which is one reason lower face planning tends to look at the whole picture. If your main concern is the fold beside the nose, our guide to nasolabial fold filler in Toronto covers that area separately.
| Feature | Nasolabial folds | Marionette lines |
|---|---|---|
| Where they run | From beside the nose toward the mouth corners | From the mouth corners downward toward the chin |
| Main contributors | Midface volume shift, skin laxity, smile movement | DAO muscle pull, lower face volume loss, jowl formation, skin quality |
| Where Botox fits | Rarely the main tool | Sometimes used on the DAO to reduce downward pull |
| Where filler fits | Often the main tool | Often used for deeper folds, alone or with Botox |
Muscle pull or volume loss: the question that shapes the plan
If I had to pick one idea that helps people make sense of this area, it would be this. Some marionette lines are mostly dynamic, meaning they deepen when the DAO contracts as you talk, frown or press your lips together. Others are mostly static, meaning they are visible at rest because of lost volume and skin changes. Most people have a blend.
How a clinician tells the difference
A good assessment usually involves watching your face at rest, while you smile, while you speak, and while you deliberately pull your mouth corners down. A line that softens a lot at rest is more likely to respond to muscle relaxation. A line that stays put, or a fold with a shadow underneath it, points more toward volume and skin quality. You can do a rough version at home in a mirror, though it will never replace an in-person look.
What that means for Botox
Botox acts on muscle activity. When the DAO is relaxed, the mouth corners tend to sit a little higher and the folds beside them can look less pronounced. It cannot fill a groove, tighten loose skin or rebuild support. The Mabrie Facial Institute and several other clinic sources describe Botox as best suited to milder, movement-related lines, and that fits what I see described most consistently in the literature.
| What you notice | Likely main driver | Approach often discussed |
|---|---|---|
| Corners of the mouth turn down when you talk or frown | Active DAO pull | Botox to the DAO |
| Line is clearly visible at rest, with a shadow beneath it | Volume loss and skin changes | Hyaluronic acid filler, possibly with skin quality treatments |
| Both a downturned corner and a visible fold at rest | A mix of muscle pull and volume | Botox and filler planned together |
| Fullness along the jaw next to the lines | Jowl formation and skin laxity | Broader lower face plan, sometimes with energy-based skin tightening |
How Botox works on the DAO muscle
Botox is a purified form of botulinum toxin that temporarily blocks the signal between a nerve and the muscle it controls. Injected in very small amounts into the DAO, it reduces how forcefully the muscle can pull. The effect is not instant. Our service page describes initial effects within a few days and full results at roughly two weeks.
Why this is an off-label use
This is worth stating plainly. A published review of lower face injections by Mess describes Botox use in the DAO for marionette lines as off-label, meaning it is a professional judgment call rather than one of the specific uses listed in the product’s Canadian authorization. Off-label does not mean improper. Many accepted medical practices are off-label. It does mean the decision should come from a qualified clinician who explains the reasoning, the limits of the evidence and the risks, and who documents your consent.
What the published evidence looks like
The evidence here is thinner than it is for the forehead or frown lines. The Mess article describes a single-patient treatment sequence that combined small-dose DAO Botox with hyaluronic acid filler and deoxycholic acid, and reported that the patient’s satisfaction score improved from 44 to 84.5 percent. The authors themselves note that a formal multicentre study is needed. I would treat that as a useful description of how clinicians think about the area, not as proof of what your own result will be.
Small doses, and why that is the whole point
The DAO is a thin muscle sitting close to other muscles that shape your smile and lower lip. That is why conservative, precise dosing matters so much here. Some sources cite total doses of only a few units, and the Mess report used a very small amount in the muscle. The right dose for you depends on muscle strength, anatomy and goals, and your injector should decide it at assessment. Our service page says the same thing, that units vary with muscle strength and that a specialist determines the appropriate dose.
What happens during a consultation and treatment visit
A first appointment tends to be more conversation than procedure, and I think that surprises people who expect to be in and out with a needle in ten minutes. You talk through what bothers you, your medical history, medications and supplements, prior treatments, and what a natural result looks like to you.

The assessment
Your injector looks at your face in repose, in motion, and from different angles and lighting. They will usually ask you to smile, speak and pull your mouth corners downward. This tells them how active the DAO is and how it relates to the neighbouring muscles. It is also the point where a candid clinician might say that filler, or a different approach altogether, is a better first step for you than Botox.
The injection itself
Treatment is quick. A few tiny injections are placed on each side using a fine needle, and most people describe a slight pinch, which matches the description on our service page. Any specifics of placement and dose are decided by the injector on the day, so I will not describe them as a fixed recipe here.
Follow-up
Because the effect builds over about two weeks, a check-in at that point is a sensible way to see how the muscle has responded. In a delicate area like this, starting conservatively and adjusting later is generally kinder to your expression than starting high.
Timeline: when results appear and how long they last
The following ranges reflect what our service page and general clinical sources describe. Individual response varies with metabolism, muscle strength and dose.
| Stage | What people commonly notice |
|---|---|
| Same day | Tiny marks or mild redness at the injection points that usually settle quickly |
| Days 3 to 5 | The first hints of relaxation, sometimes a feeling that the mouth corners sit slightly differently |
| About 2 weeks | Full effect, and the usual time for a follow-up review |
| Around 3 to 4 months | Movement gradually returns; our service page describes maintenance every 3 to 4 months and results lasting 3 to 6 months depending on the person |
Botox is temporary, and lines that were etched in by volume loss will return to whatever your face would have done anyway. It does not accelerate ageing when it wears off.
Side effects, risks and warning signs
Most reactions after Botox are mild and short lived. Because the DAO sits next to muscles that control your lower lip and smile, it is worth understanding the more specific risks of this area.
Common and expected
These include mild swelling, redness, small bruises and occasional tenderness at the injection points. Our service page lists minor swelling or bruising as the usual effects.
Less common, area-specific
If toxin spreads to a neighbouring muscle, you can get a temporarily uneven smile or a change in how the lower lip moves. The Mess review lists marginal mandibular nerve involvement among the possible complications of lower face injections. These effects are temporary and fade as the Botox wears off, but they can be unsettling for a few weeks, which is why careful placement matters.
| What you notice | Usually means | What to do |
|---|---|---|
| Small bumps, redness or a pinprick bruise | Normal response to injection | Cool compress if comfortable; usually settles within a day or two |
| Mild tightness or a slightly different feel when speaking | Botox taking effect | Wait; mention it at your follow-up |
| Smile looks uneven or the lower lip moves differently after a week | Spread to a nearby muscle, temporary | Contact the clinic so your injector can review it |
| Difficulty swallowing, breathing or speaking, or widespread weakness | Rare and potentially serious | Seek urgent medical care |
| Hives, facial swelling, or trouble breathing shortly after treatment | Possible allergic reaction | Seek emergency care |
Who is a good candidate, and who may need a different plan
Botox for marionette lines suits adults whose mouth corners turn down mainly because of muscle activity, and who accept that results are temporary. It is not a universal answer, and I would be wary of any consultation that promised otherwise.
Situations where a different approach may come first
If your lines are deep and visible at rest, hyaluronic acid filler or skin quality treatments may do more than Botox. If you are pregnant or breastfeeding, have a neuromuscular condition, an infection at the injection site, or a known allergy to an ingredient in the product, Botox is generally not appropriate, and your provider will want a full history first. Certain medications can also matter, so bring a complete list.
When a medical referral is the better next step
If you have new or progressive facial asymmetry, difficulty moving one side of your face, numbness, or unexplained swelling along the jaw, that calls for a physician’s assessment before any cosmetic treatment. A consultation that ends with “please see your doctor first” is a good outcome, not a failed one.
Marionette lines Botox compared with filler and other options
Botox is one tool among several, and often not the first one. Cleveland Clinic lists botulinum toxin, dermal fillers, chemical peels, laser resurfacing, microneedling and thread lifts as non-surgical options, and notes that surgery is the only long-lasting solution for deeper cases.
| Option | What it addresses | Limits worth knowing |
|---|---|---|
| Botox (DAO) | Downward muscle pull at the mouth corners | Does not add volume; off-label; temporary |
| Hyaluronic acid filler | Volume loss and deeper folds; see our dermal filler service | Temporary; needs careful placement; can look overdone if too much is used |
| Medical-grade peel | Skin texture and fine surface lines; see medical-grade peels | Does not change volume or muscle pull |
| Microneedling | Skin quality and collagen stimulation; see microneedling | Gradual, modest change; several sessions are common |
| Energy-based skin tightening | Mild laxity; see skin tightening | Not a substitute for volume replacement in deeper folds |
| Surgery | Significant laxity and deep folds | Longer recovery; a surgeon’s assessment is needed |
Botox and filler together
The Mess report describes DAO relaxation as something that potentiates soft-tissue filling by softening the pull of the muscle on the treated line. In plain language, if the muscle keeps tugging the corner down, filler placed in the fold has to work against that tug. Relaxing the muscle first, or in the same visit, is a common reasoning for combining them. Hyaluronic acid effects generally last from about six months to a year or more, according to Health Canada’s cosmetic injections guidance, so the two treatments are on different clocks.
Where the rest of the lower face comes in
Marionette lines rarely exist alone. Fullness along the jaw, loss of definition and cheek volume all influence how the mouth corners are supported. Our guides to cheek filler and non-surgical jawline sculpting explain how neighbouring areas can change what the lower face needs. If your chin has visible dimpling or a tight, pebbled texture, that involves a different muscle, and our chin dimples Botox page explains it.
Aftercare: the first day or two
Aftercare for a small lower face Botox treatment is mostly common sense, and it can differ a little between clinics, so follow your own provider’s instructions where they differ from mine.

What to do
Keep your face upright for the first few hours, use a cool compress if you have mild swelling, and wear sunscreen daily, since UV exposure is one of the contributors to lines in the first place.
What to skip
Our service page advises avoiding intense exercise for at least 24 hours to reduce swelling and bruising. Many clinics also suggest skipping heavy pressure or massage over the treated area, and alcohol, for the first day, though your injector’s own instructions apply.
| Timeframe | Suggested approach |
|---|---|
| First 4 hours | Stay upright, avoid pressing or rubbing the treated area |
| First 24 hours | Avoid intense exercise; keep skincare gentle |
| Days 2 to 7 | Resume normal routine; watch how your smile and speech feel |
| Around 2 weeks | Review the full effect with your injector |
Lifestyle factors that influence how marionette lines look
None of these will erase a line, and none of them are moral obligations. They just tend to shift the pace.
Sun protection
UV exposure breaks down collagen, and Cleveland Clinic lists sun exposure among the contributors. A broad-spectrum sunscreen worn daily is the single most useful habit for skin quality around the mouth.
Smoking and repetitive lip pursing
Smoking and repetitive lip pursing are both named among the contributors. If you smoke, that is a personal decision and I am not going to lecture about it, but it is relevant information when a provider talks about how long skin quality treatments might last.
Sleep, hydration and skincare
Good sleep, a gentle routine and a moisturizer suited to your skin help the surface look its best, though none of these change muscle pull or volume. Our guide to PRP microneedling explains one option for skin quality, for readers who want to explore that side of things.
Cost factors to understand before you book
I am not going to quote a price, partly because the number depends on your plan and partly because prices change. What I can do is explain what usually moves the total. Botox and filler are cosmetic treatments, so OHIP does not cover them.
| Factor | Why it changes the total |
|---|---|
| Dose needed | Muscle strength and treatment goals affect how much product is used |
| Whether filler is added | Filler is priced by amount used and is a separate product from Botox |
| Number of visits | A follow-up review or touch-up may be part of the plan |
| Maintenance schedule | Botox is temporary, so ongoing visits every few months add up over a year |
| Provider experience and setting | Lower face injections reward precision, and that has value |

Marionette lines Botox compared with other Botox areas
Lower face Botox behaves differently from the upper face, mostly because the muscles are closer to structures that control speech, eating and smiling.
| Area | Main goal | Further reading |
|---|---|---|
| Marionette lines (DAO) | Reduce downward pull at the mouth corners | This guide |
| Crow’s feet | Soften expression lines at the outer eye | Crow’s feet Botox |
| Glabellar lines | Soften the vertical lines between the brows | 11 lines Botox |
| Bunny lines | Soften nose scrunch lines | Bunny lines Botox |
| Platysmal bands | Soften vertical neck bands | Platysmal bands Botox |
| Masseter | Jaw slimming or clenching relief | Masseter Botox |
Common misconceptions
“Botox will fill the lines”
It will not. Botox relaxes muscle, and any softening comes from reduced movement. Filling is a job for filler.
“More units means a better lift”
In the DAO, more is not necessarily better. Overtreatment risks an uneven smile or a stiff lower lip, and there is rarely a reason to rush.
“Botox and filler are interchangeable”
They solve different problems. Choosing between them, or combining them, is exactly what a consultation is for.
“Marionette lines mean I look sad”
They mean your face has changed in a common, ordinary way. Whether you want to soften them is entirely your choice, and choosing not to treat them is a perfectly good decision.
Questions worth asking at your consultation
A few questions tend to bring out useful answers. Do my lines look more like muscle pull or volume loss? Is Botox in this area a good fit for me, and how would you describe the off-label nature of it? What would a conservative first plan look like? When would you review the result? What happens if my smile feels uneven? How does the plan change if I add filler later?
Choosing a qualified provider
The Rejuvenation Med Clinic team page lists our medical director and clinical staff, and it is reasonable to ask who will be injecting you and what their training is. Lower face injections reward experience, so I would ask how often they treat this area, how they handle complications and what the follow-up looks like. We also have a general injectable treatment FAQ and a comparison of Dysport and Botox if you are curious how neuromodulators differ.
Frequently asked questions
Can Botox fix deep marionette lines?
Botox alone usually cannot fix deep lines that are visible at rest, because those are mostly caused by volume loss and skin changes rather than muscle movement. It may soften the downward pull that deepens them. Deeper folds are often discussed with hyaluronic acid filler, sometimes combined with Botox, after an in-person assessment.
How does Botox help marionette lines?
Botox relaxes the depressor anguli oris (DAO), the muscle that pulls the corners of the mouth downward. With less pull, the mouth corners can rest a little higher and the folds beside them can look softer. It does not add volume or tighten skin, so results depend on how much of your line is muscle driven.
Is Botox for marionette lines approved by Health Canada?
A published review of lower face injections describes Botox use in the DAO for marionette lines as off-label. That means it is a professional judgment rather than a specifically listed use. Off-label does not mean improper, but your provider should explain the reasoning, the evidence and the risks before you consent.
How many units of Botox are used for marionette lines?
The dose varies with muscle strength, anatomy and goals, and only your injector can decide it at assessment. Some sources cite small totals of a few units, and the published case we reviewed used a very small amount. Our service page notes that a specialist determines the appropriate dose for each person.
How long does Botox for marionette lines last?
Our service page describes results lasting roughly 3 to 6 months depending on metabolism and muscle activity, with maintenance every 3 to 4 months. Initial effects show within a few days and the full effect at about two weeks. Botox is temporary, and movement gradually returns as it wears off.
Is Botox or filler better for marionette lines?
It depends on the cause. Botox suits lines driven by muscle pull, while hyaluronic acid filler suits lines driven by volume loss and deeper folds. Many people have a mix of both, which is why the two are sometimes planned together. A consultation is the best way to work out which fits you.
Can Botox and filler be combined for marionette lines?
Yes, and it is a common approach. Published lower face reports describe relaxing the DAO to soften the muscle pull on the treated line, which may support filler placed in the fold. The two products work on different timelines, since filler often lasts longer than Botox, so your plan will account for that.
Does Botox for marionette lines hurt?
Most people describe a slight pinch, and our service page notes that anaesthesia is not usually required. The area near the mouth can feel a little more sensitive than the forehead for some people. If you are nervous about discomfort, tell your injector, who can suggest ways to make the visit more comfortable.
What are the risks of Botox in the DAO?
Common effects are mild swelling, redness and small bruises. The DAO sits near muscles that control the lower lip and smile, so spread of the product can rarely cause a temporarily uneven smile or lip movement. Published reviews list marginal mandibular nerve involvement as a possible complication. These effects are temporary but worth discussing beforehand.
Will Botox for marionette lines change my smile?
When placed carefully, it should not meaningfully change how you smile, though the mouth corners may feel slightly different as the DAO relaxes. If your smile looks uneven a week after treatment, contact the clinic so your injector can review it. Any change from Botox is temporary.
Who should avoid Botox for marionette lines?
Botox is generally not appropriate during pregnancy or breastfeeding, with certain neuromuscular conditions, with an infection at the injection site, or with a known allergy to an ingredient in the product. Some medications also matter. Bring a full medical history and medication list so your provider can decide whether it is right for you.
What is the difference between marionette lines and nasolabial folds?
Nasolabial folds run from beside the nose toward the corners of the mouth, while marionette lines start at the mouth corners and continue down toward the chin. They often appear together and influence one another. Treatment planning usually considers both, along with cheek volume and the jawline.
Can marionette lines be prevented?
Not entirely, since genetics and normal ageing play a large role. Daily sunscreen, avoiding smoking and looking after your skin can slow some contributors, according to Cleveland Clinic. Preventive treatment is a personal choice, and it is reasonable to wait until the lines actually bother you.
Are there non-injectable options for marionette lines?
Yes. Options often discussed include medical-grade peels, microneedling, energy-based skin tightening and, for significant laxity, surgery. Cleveland Clinic lists chemical peels, laser resurfacing, microneedling and thread lifts alongside Botox and filler. These mainly improve skin quality rather than replace volume or change muscle pull.
Is marionette lines Botox covered by OHIP?
No. Botox for marionette lines is a cosmetic treatment, and OHIP does not cover cosmetic injectables. Ask your provider for a written breakdown of costs at your consultation, including any follow-up visit, so there are no surprises. Our finance page has current information on payment options.
Can I have Botox for marionette lines if I already have Botox elsewhere?
Yes, many people treat several areas in the same visit, and your injector calculates the total dose across everything treated. Because facial muscles work together, treating one area can change how a neighbouring area looks, so it helps to tell your injector what you have had before.
Should I see a doctor before treatment?
See a physician first if you have new or progressive facial asymmetry, trouble moving one side of your face, numbness or unexplained swelling along the jaw. For ordinary expression-related lines beside the mouth, a med spa consultation is a reasonable starting point, and your provider will tell you if a medical assessment is needed.
Marionette lines Botox is one part of our broader Botox services in Toronto, and if you would like a plain conversation about whether it, filler, both, or neither makes sense for you, you can request a consultation. A consultation does not commit you to anything, your plan can change after an individual assessment, and if Botox is not the right fit for what you are seeing, we will say so directly.
Lines beside the mouth often sit next to early jowling, and our guide to jowls treatment in Toronto explains how the two are planned together.
