Mouth Corner Filler in Apgujeong, Gangnam
Mouth corner filler at Live Young Clinic in Apgujeong, Gangnam supports downturned corners of the mouth that can make a resting face look sad, tired or stern. It suits people whose lip corners droop even when relaxed. Dr. Song assesses the corners and the muscles pulling them down, then designs subtle support, sometimes paired with Botox, for a softer expression.

Why do the corners of the mouth turn down?
The corners of the mouth, known as the oral commissures, can begin to point downward with age. Tissue support around the mouth thins, and a small muscle called the depressor anguli oris continues to pull the corners down. The result is a mouth that looks unhappy or tired even when you feel relaxed.
This is different from marionette lines, which run from the mouth corners toward the chin. Downturned corners are a small, specific change right at the edge of the lips, although the two often appear together as the lower face ages.
Who might benefit?
People who are told they look sad or annoyed when they are not, or who notice their mouth corners drooping in photos, often consider this treatment. It is well suited to mild to moderate downturn. When the muscle pull is strong, Dr. Song may suggest a small amount of Botox to relax it, since filler alone could be pulled down again.
- Corners that point down at rest
- Unintended sad or stern expression
- Early lower-face ageing around the lips
- Sometimes combined with Botox for muscle pull
How Dr. Song treats the mouth corners
In Needs Mapping, Dr. Song studies your mouth at rest, when you smile and when you frown, and gently feels how strongly the depressor muscle pulls. She also looks at the lower lip, chin and marionette area, since these influence how the corners sit.
The Curated Plan might include small support beneath each corner, gentle border refinement, or a combination with Botox. Tailored Treatment keeps amounts minimal to avoid a stiff or puffy look around the lips. The aim is a neutral, relaxed resting expression that still lets your smile move freely.
Safety and aftercare
The area around the mouth moves constantly, so mild swelling, tenderness or small bruises are common after treatment and typically settle over time. Rare vascular complications can occur with any filler, so choose an experienced doctor and report increasing pain or skin colour change promptly.
For a short time, avoid exaggerated mouth movements, pressing the area, very hot foods, saunas and alcohol. Try to chew gently on the first day. If Botox is combined, Dr. Song will also explain what to avoid for that part of the treatment.

Frequently asked questions
Is mouth corner filler the same as marionette line filler?
No, though they are related. Mouth corner filler supports the corners of the lips themselves, while marionette filler softens lines running toward the chin. Many people benefit from one; some need both. Dr. Song will advise after assessment.
Why would Botox be added?
A small muscle pulls the mouth corners downward. If it is strong, relaxing it with a small amount of Botox can help the corners sit higher and may make filler results look more natural. Dr. Song decides this at consultation.
Will my smile look different?
The goal is to change your resting expression, not your smile. Dr. Song checks your mouth in motion and uses small amounts to preserve natural movement when you talk and laugh.
Is there downtime?
Downtime is usually limited, but swelling or bruising around the mouth can occur. If you have events planned in Seoul, allow a few days of buffer and discuss timing with the Apgujeong clinic.
How long do results last?
Because the mouth moves frequently, longevity varies from person to person. The product used, the amount and individual metabolism all play a role. Dr. Song will explain what is realistic for you during consultation.
