Marionette lines are the two creases that run from the corners of the mouth down towards the chin. They frame the lips the way strings frame a puppet’s hinged jaw, which is where the name comes from. In a younger face the corners of the mouth sit level, or tip gently upwards. As the years pass they drift down. The skin folds along the same path and a shadowed groove settles in. At rest the face can start to look stern or sad. That’s why more than any other sign of ageing, marionette lines bother people most as they read as an expression rather than a wrinkle. There are a number of possible treatments and the right approach depends on the causes and severity of your lines. In this article, we’ll walk through what causes marionette lines and the treatments that can genuinely make a difference.

What Causes Marionette Lines?
Marionette lines are rarely a skin problem on their own. They are the surface sign of several deeper changes happening together in the lower third of the face. That is why a single treatment so often disappoints. Three layers are involved at once.
The first is structure. From our mid-twenties the skin makes less collagen and elastin, so it thins and loses its spring. Meanwhile the fat pads that once plumped the cheek shrink and slide downwards, and the bone of the jaw and chin quietly recedes. This descent of the facial fat compartments leaves the lower face poorly supported. Ligaments tether the skin at the jawline, so the loosened tissue above pools and folds over them. The result is a groove running down from the mouth. It tends to arrive alongside jowls and a loss of facial volume higher up.
The second is muscle. A small paired muscle called the depressor anguli oris runs from each mouth corner down to the jaw, and its whole job is to pull the corners down. With age its resting tone wins out over the muscles that lift the mouth, so the corners turn down even at rest. Research on the muscle confirms that easing this downward pull on the mouth corner is central to softening the line. As such, so many marionette treatments target it directly.
The third is the skin itself. It grows thinner and drier, and it is creased by the thousands of times a day we talk, smile and purse our lips. Several things speed all of this up:
- Sun exposure: Ultraviolet light is the biggest external cause of collagen and elastin breakdown. A lifetime of it shows up as earlier, deeper folds around the mouth.
- Smoking: Pursing a cigarette etches vertical lines into the area, and the smoke itself starves the skin of collagen and oxygen.
- Weight changes: Significant or rapid weight loss strips away some of the fat that supports the lower face, leaving the skin with less to drape over.
- Genetics and anatomy: A naturally heavier lower face, thinner skin or a strong downward muscle all make marionette lines more likely, and they often run in families.
Generally it is a mix of all three layers, in different proportions. Whether yours is driven mainly by muscle, by lost volume or by skin quality is what decides the right treatment. It is also why the best results usually come from tackling more than one at once.
Skincare for Marionette Lines
Let’s be straight about what skincare can and can’t do here. Unfortunately, it will not lift a fold that has already formed. That is a structural problem, and a cream works at the surface. However, what it can do is change how the area reads. Skin that is thicker, smoother and well hydrated catches the light differently. The groove casts a softer shadow, and the fine lines feathering around it settle back. Skincare is also the one part of the plan that is entirely in your hands at home. Better still, it makes every in-clinic treatment hold longer.
The ingredient doing the heavy lifting will be retinoids like tretinoin which speed up cell turnover. More importantly here, it also stimulates new collagen in the dermis over a few months, which thickens and firms the perioral skin so it creases less. One caveat matters around the mouth. The skin here is thin, easily irritated and prone to perioral dermatitis. So any retinoid needs gentle introduction building up strength and frequency as your skin adjusts.
A few supporting ingredients pull their weight too. Vitamin C is worth using each morning. It helps defend collagen against daily damage, and its brightening effect lightens the very shadow that makes a marionette line look deeper. Niacinamide and peptides shore up the skin barrier and its resilience, which matters in an area that folds all day long. A humectant like hyaluronic acid plumps the surface and blurs fine lines, though that effect is superficial and washes off. Think of it as polish rather than repair. Sunscreen, finally, is non-negotiable. Sun damage is one of the biggest accelerators of the whole process. A daily broad-spectrum SPF 30 or higher is the most protective step you can take, and it guards every gain the rest is making.
A consistent routine for ageing skin is outstanding prevention in your twenties and thirties. It can help smooth early lines too. Just be realistic about time and give it at least three to six months of consistent use before you judge any skincare outcomes. For more established folds, skincare can help lay the the foundation for other treatments to build.
Dermal Fillers
Dermal fillers are the most direct non-surgical treatment for a marionette line. But the modern approach is cleverer than simply filling the crease. A good injector reads the area as a collapsed scaffold and rebuilds it from the structure down. A firmer hyaluronic acid gel goes higher in the cheek, jaw and chin. This restores the shelf the mouth corner has lost and re-supports the whole lower face. A little can then lift the corner of the mouth itself. Finally, a soft, fine gel is feathered into the crease to soften what remains. Treating only the line, without rebuilding the support beneath it, tends to look bolted-on and rarely lasts.
Results are immediate. Usually they hold for 6 to 18 months, depending on the product and how fast your body breaks it down. The evidence is clear that marionette lines respond best to a combined approach: filler for the structure, a muscle relaxer for the pull. Filler does have real limits. It cannot tighten loose skin. Overfilling weighs the lower face down and flattens the natural line between lip and chin. The area is also rich in blood vessels, so the most serious risk is vascular occlusion, where filler blocks a vessel. This should only ever be done by an experienced medical injector, ideally with a blunt cannula near the riskier spots.
Botox
This is where Botox has a genuinely useful, almost surgical role. A few units of botulinum toxin go into the depressor anguli oris, the muscle dragging each mouth corner down. Released from that pull, the muscles that lift the mouth win back a little ground, and the corners settle into a more neutral position. However, the depressor sits close to other muscles that shape the smile, so accuracy is everything. However, on its own it won’t fill a set groove or replace lost volume. That is why it works best alongside filler, and it can be paired with treatment of the neck bands for a broader lift. The effect softens after three to four months. Too much, or a dose in the wrong place, can flatten the smile or weaken the lips’ seal, so this is not a place to cut corners.
Skin Boosters & Polynucleotides
Skin boosters such as Profhilo and Volite sit in a different category to filler, as do polynucleotide injections. Instead of adding shape, they improve the quality of the skin itself. They deeply hydrate it and prompt gentle collagen and elastin production across the lower face. For marionette lines that means softer, springier, less crepey skin around the mouth. It is most useful for early lines, or as prevention before a fold properly sets. These treatments partner well with filler and with good skincare. On their own, though, they won’t shift a deep crease. A typical plan is two or three sessions a few weeks apart, with a top-up once or twice a year.
Microneedling and Radiofrequency
Microneedling creates thousands of tiny controlled punctures. These trigger the skin’s own repair response, laying down fresh collagen and elastin that firm it over the following months. Then comes radiofrequency, adding heat to the deeper layers. Devices like Morpheus8 do exactly this in radiofrequency microneedling, which adds a tightening effect and suits a lower face where mild laxity and texture sit together. Expect three or four sessions, four to six weeks apart, with a day or a few of redness afterwards. As with the other skin treatments, the results build gradually rather than overnight. Like the other skin-quality treatments, it improves the canvas around a marionette line without erasing a deep one.
Chemical Peels
Chemical peels use an acid solution to lift away the outer layers of skin and prompt renewal beneath. Often, lighter peels refresh tone and texture across the lower face. A medium-depth peel reaches further into the dermis, where it can soften the fine etched lines that feather around the mouth and corners. Peels improve skin quality and early lines rather than deep folds, and they suit a course rather than a one-off. The area needs experienced hands. Perioral skin is delicate, and deeper peels carry a risk of post-inflammatory hyperpigmentation, especially in richer skin tones.
Thread Lifts
Thread lifts use absorbable threads, usually made of the same material as dissolvable stitches. They are passed under the skin and gently tightened to reposition sagging tissue and lift the drooping corner, stimulating a little collagen as they break down. The immediate lift can be appealing, and the downtime is short. They are also one of the more divisive options. However, results tend to be modest and fairly short-lived. Complications like puckering, asymmetry or, rarely, nerve or vessel damage are very operator-dependent. For this reason, we generally recommend avoiding them. However, if you’re tempted just find a qualified and experienced medical practitioner working in a regulated practice.
Surgery
When marionette lines are deep and the real problem is significant sagging, surgery is the only thing that genuinely removes them. A lower facelift, often combined with a neck lift, repositions and tightens the deeper structures and removes the excess skin. Surgeons frequently add fat grafting to replace the lost volume, so the result looks restored rather than pulled. The outcome lasts in a way nothing non-surgical can match. However, this is major surgery, with a general anaesthetic, one to two weeks of meaningful downtime and the usual surgical risks. So it tends to be reserved for pronounced sagging where there are no non-surgical alternatives.
So Which Marionette Line Treatment is Best?
There is no single best treatment, because the right one depends on what is driving your marionette lines and how deep they are. If the main culprit is a strong downward muscle pull, then a few units of Botox can make a quietly dramatic difference. Filler can help replace lost volume and rebuild the scaffold. Skincare, skin boosters, microneedling and peels can all help improve the skin and smooth fine lines or wrinkles. However, where there is significant sagging, only a surgical face lift will truly address it. Moreover, marionette lines tend to respond best to a combination rather than a single fix. They also tend to co-exist with jowls, smile lines, a softening jawline and neck. As such, it pays to read the lower face as a whole.
Encouragingly, marionette lines can be prevented by protecting your skin from the sun, not smoking and keeping up a proper routine all change the trajectory. Beyond that, there are arrange of skincare, non-surgical and surgical treatments. The best treatment for you will depend on the severity of your marionette lines, other skin concerns overall health, goals and lifestyle.
