- Filling the line alone is usually insufficient and can weigh down the face
The marionette line runs from the corner of the mouth toward the chin and gives the face a tired or sad look, even when the person is fine. It is usually treated as a "fold" to be filled, but clinical experience shows that the line is the symptom of a broader change in the lower third.
This page explains the causes and the plan with care. It connects with downturned mouth corners, sad-looking mouth and man with nasolabial folds.
What forms the marionette line?
The marionette line forms between the corner of the mouth and the contour of the chin. Several factors add up:
| Factor | What happens | Effect on the line |
|---|---|---|
| Loss of support at the mouth corner | The commissure descends | Longer, deeper line |
| Fat descent (jowl) | Volume accumulates below the mouth | Fold over the contour |
| Depressor anguli oris muscle | Pulls the corner downward | Pronounced line and sad expression |
| Loss of chin projection | The chin recedes | Accentuated prejowl sulcus |
| Lax skin | Loses elasticity | The fold remains at rest |
The depressor anguli oris muscle and the modiolus (the point where muscles converge at the corner of the mouth) are at the center of the dynamics. The neighboring prejowl sulcus completes the picture.
How to assess the line
The assessment is dynamic and needs to be compared with the whole.
The relationship with the jawline is in sagging jawline, and the surrounding skin appears in loose skin around the mouth.
What the plan considers
At the discretion of the licensed professional, the plan is usually built in layers:
- Support of the mouth corner: a small volume that holds up the commissure. See mouth corner filler.
- Contour and chin: giving support to the jowl and chin reduces the weight on the line. See jawline filler and chin filler.
- Dynamics: toxin in the depressor, in selected cases.
- Filling the line: afterward, and in a small amount, when needed.
- Skin: quality and firmness, with other approaches.
Order matters: filling the marionette line before giving support to the mouth corners and the contour increases the risk of heaviness and an artificial look. See mouth corners, marionette lines and chin: combining.
Risks
Swelling, bruising, asymmetry, nodules and irregularities. The perioral and chin region receives branches of the facial and labial arteries, and vascular complications are rare and serious; hyaluronidase must be available when hyaluronic acid is used. Toxin in the perioral muscles can cause smile asymmetry and changes in speech or chewing, usually temporary.
How to show it in Harmy
The Mouth Corner point in Harmy simulates support of the commissure, and the Jawline and Chin complete the set. Show each area on its own and then the combination, so the patient understands that the line improves through the sum of support. The "Maintenance" shortcut suggests the line at 1 ml at Subtle intensity, only as a starting point.
Common mistakes with marionette lines
The first mistake is filling the fold without giving support to the mouth corner and the contour. Product in the fold pushes the excess downward and weighs down the chin. The second is ignoring the dynamics: if the depressor anguli oris dominates, the line comes back, and the conversation about toxin needs to happen.
Another mistake is treating only the side that is visible at rest. Many patients only show the marionette line when they laugh, talk or look serious, and assessment in motion reveals the weight of each factor. It is also a mistake to forget the skin: a fold with lax, thin skin tends to reappear.
Finally, do not forget the emotional impact. The marionette line gives the face a sad look, and the patient often comes with the concern that people ask if they are upset. Acknowledging this humanizes the consultation and guides the plan.
Stages and follow-up
Structure the plan: support of the mouth corner and contour, assessment, dynamics, and only then the fold. Record photos at rest, smiling and with a sad expression, before and after each stage. Agree on the reassessment interval and the possibility of reversal with hyaluronidase when hyaluronic acid is used. Give guidance on warning signs, such as severe pain or a change in skin color. At follow-ups, keep the same light and position conditions so the comparison is fair. A patient who sees the progress in stages trusts the process more and tends to accept conservative plans better.
Patient profiles and plan adjustments
In patients in their 40s and 50s, the marionette line is usually mild and responds to discreet support plans. In patients over 60, laxity and bone loss limit the effect of injectables and call for a frank conversation.
People with a broad, very expressive smile have more pronounced folds, and the plan should consider the dynamics. Patients with a retruded chin benefit from projection before the line is treated.
In every case, ask how the patient perceives their own expression. Many report that others think they look sad, and that social perception is a good measure of treatment success, as long as the promise is realistic.
Wrap-up
Record photos at rest and smiling, the dominant cause, the staged plan and the guidance on skin and habits. See also deep oral commissure and double chin with a small chin. Volumes and techniques are at the discretion of the licensed professional, in accordance with the rules of their professional council in Brazil.
Frequently asked questions
What causes deep marionette lines?
The sum of lost support in the lower third, descent of fat (jowl), the action of the depressor anguli oris muscle and lax skin. Each patient has a different combination.
Does filling only the line fix it?
Usually it is not enough. Treating the line alone can improve the fold, but the cause is usually in the support of the mouth corner, the contour and the chin, and the plan considers those layers.
Does toxin have a place in treating marionette lines?
It may be considered in selected cases, at the discretion of the licensed professional, when the depressor anguli oris muscle is dominant. It requires careful assessment because of the risk of altering the smile.
Are marionette lines the same as nasolabial folds?
No. The nasolabial fold runs from the side of the nose to the mouth. The marionette line runs from the corner of the mouth toward the chin, and the two can coexist.
