Marionette Line Fillers  in Belgium: what to expect and where to find trusted clinics

Marionette Line Fillers — Full Guide: Benefits, Risks, Recovery, Prices & Trusted Clinics in Belgium

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.

What are marionette lines?

They’re the downward folds that run from the corners of the mouth to the chin. Over time, volume loss and gravity make them deeper, creating a sad or tired appearance.

How do marionette line fillers work?

A hyaluronic acid gel is injected under the skin to restore lost volume and lift the corners of the mouth. The filler attracts water and supports the tissues, smoothing the lower face without surgery.

Who can benefit from this treatment?

Anyone noticing sagging mouth corners or a tired look around the lower face. It’s suitable for both men and women looking for a natural lift without surgery.

How long does the treatment take?

About 30 to 45 minutes, including consultation, facial assessment, and injections. No downtime is required, and most people return to normal activities the same day.

Is it painful?

Only mildly uncomfortable. Most fillers contain lidocaine, and your doctor can apply a numbing cream to ensure comfort.

When will I see results?

Results are visible immediately, with final refinement after a few days as the product integrates with the skin.

How long do the results last?

On average 9 to 15 months, depending on your metabolism and the filler brand used. A touch-up once a year helps maintain results.

How much filler is needed for marionette lines?

Typically 0.5 to 1 ml per side is enough for a natural result. The exact volume depends on your facial structure and line depth.

How much does it cost in Belgium?

Prices range from €250 to €600, depending on filler brand, volume, and injector experience.

Are marionette line fillers safe?

Yes, when performed by a qualified doctor. Side effects like redness or bruising are mild and temporary. Serious complications are very rare.

Who can perform filler injections in Belgium?

Only licensed physicians. It’s illegal for beauticians or non-medical staff to inject fillers, even under supervision.

Can marionette fillers be combined with other treatments?

Yes — many patients combine them with chin, jawline, or cheek fillers to restore natural harmony to the lower face.

Will my results look natural?

Absolutely. The goal is not to change your features but to refresh your natural expression. A good result should be invisible — you’ll just look rested and confident.

Can I go back to normal activities afterward?

Yes. You can resume daily life right away, avoiding strenuous exercise, saunas, or facial massages for 24–48 hours.
