What are marionette line fillers?
Marionette lines are the vertical folds that extend from the corners of the mouth down toward the chin.
Over time, facial fat and collagen decrease, the skin loses elasticity, and these lines deepen — giving the face a tired or sad expression.
Hyaluronic acid (HA) fillers provide a gentle, non-surgical way to soften marionette lines, lift the mouth corners, and restore lower-face balance.
The treatment rehydrates and supports the skin, restoring a fresh and relaxed expression without changing natural features.
Results are subtle, immediate, and natural-looking — without scars or downtime.

Who is this treatment for?
This treatment is suitable for women and men who want to:
- Correct or soften visible marionette lines;
- Lift downturned mouth corners;
- Improve the mouth-to-chin transition;
- Rebalance the lower face without surgery;
- Restore a relaxed and confident expression.
It’s often combined with chin or jawline fillers for an overall facial harmony and natural rejuvenation.
Technique and product choice
The marionette line area lies close to important facial vessels, which makes precise technique essential.
Injection method:
- Deep injections near the bone to rebuild structure and support;
- Superficial passes to smooth the surface of the fold;
- Flexible micro-cannulas are commonly used to reduce bruising and ensure safe placement.
Filler types:
- Medium-to-firm cross-linked hyaluronic acid fillers designed for dynamic zones;
- Common brands: Juvéderm®, Teosyal RHA®, Restylane®, Belotero®;
- The texture should be firm enough to support but flexible enough to move with facial expression;
- Sometimes combined with chin support fillers for a smoother facial contour.
Expected results and longevity
Results are visible right after treatment: mouth corners appear lifted, and the overall expression looks softer and more positive.
Final results refine over several days as the filler settles naturally into the tissue.
- Average duration: 9–15 months, depending on the filler and individual metabolism;
- A yearly touch-up is often enough to maintain a natural, balanced result.
Safety and possible side effects
When performed by a qualified medical doctor, marionette line filler injections are safe and well tolerated.
Common side effects include:
- Mild redness or swelling;
- Temporary tenderness or light bruising.
Serious complications — such as vascular occlusion, product migration, or nodules — are very rare and typically linked to improper technique.
A trained injector uses slow, controlled injections and respects facial anatomy to prevent risks.
Filler volume and treatment cost
The volume needed depends on the depth of the lines and the skin’s firmness:
- 0.5 to 1 ml per side for a soft, natural correction;
- A touch-up after 3–4 weeks can refine the result if needed.
Price in Belgium: €250–€600, depending on:
- The amount of filler used (0.5 or 1 ml);
- The product brand (Juvéderm®, Teosyal®, Restylane®, Belotero®);
- The injector’s experience and clinic location.
Who can perform filler injections in Belgium?
In Belgium, only licensed medical doctors are legally allowed to perform hyaluronic acid injections.
Beauticians or non-medical staff cannot perform or supervise these treatments.
This ensures patient safety, sterile conditions, and consistent medical results.
