“People kept asking if I was upset. I wasn't. That has completely stopped since the treatment.”
Marionette lines run from the mouth corners down toward the chin. As they deepen, the corners of the mouth turn down, and a neutral face starts to read as a sad one.
The corner of the mouth filler treatment targets the downturned lines that run from the mouth toward the chin, known as marionette lines. Dermal filler is used to lift the corner and soften the line, giving the lower face a fresher, more open appearance.
The effect people notice is rarely about the line itself. It is that their resting expression changes. A downturned mouth is read by other people as tiredness, disapproval or unhappiness, regardless of what the person is actually feeling, and lifting the corner removes that misreading.
The change is deliberately small. Placed correctly, filler at the mouth corner alters how the face sits at rest without touching how it moves, so your smile, speech and expressions are entirely unchanged.

The mouth corner is one of the smallest areas we treat and one of the least forgiving. A fraction of a millimetre in the wrong direction changes the shape of the mouth rather than its position, and the result stops looking natural immediately.
This is not an area for volume. It is an area for precision, and it is assessed alongside the fold above it and the chin below it rather than in isolation.
Book nowA full consultation assesses the mouth corners, the marionette lines and the support around them. We confirm whether the downturn is best treated here or elsewhere in the lower face, and build a plan around that.
Numbing cream can be applied beforehand for your comfort. Filler is placed with precision around the mouth corners to lift the area and soften the lines. It takes around 10 minutes.
Results are immediate. You can return to work and normal daily activities straight away. Any mild swelling or tenderness typically settles within a few days.
This treatment suits you if the corners of your mouth turn down at rest, whether through age, weight loss or your natural facial structure.
A full consultation is carried out to confirm suitability. If the downturn would be better addressed elsewhere in the lower face, we will tell you.
Final pricing is confirmed at your consultation, based on the amount of product that genuinely suits you. No obligation to proceed.
