Quick answer: For marionette lines, a thread lift lifts the sagging jowl tissue that pulls the mouth corners down, while filler fills the hollow line itself and supports the corners of the mouth. Threads suit lines caused mainly by sagging; filler suits lines caused mainly by volume loss. Many faces need both for a fresh, natural look.
Key takeaways
- Marionette lines run from the corners of the mouth down toward the chin.
- They are shaped by sagging jowls, volume loss and muscle pull.
- Threads lift tissue; filler restores volume in the groove.
- Filler has less downtime; threads give a stronger lift to the lower face.
- Botox for the muscle that pulls the mouth down can help as well.
What causes marionette lines?
Marionette lines are named after puppets whose mouths move along vertical lines. They form when the jowls sag, fat under the mouth corners shrinks, and the skin loses elasticity. A muscle called the depressor anguli oris (DAO) also pulls the mouth corners down. Together these can make the face look tired, sad or older than you feel.
How does a thread lift help?
A thread lift uses dissolvable PDO or PLLA threads placed under the skin of the lower face. The threads lift the jowls and the tissue beside the mouth up and back, which reduces the weight that deepens the lines. The lift is visible right away and often lasts one to two years. It is especially helpful when the jawline has also lost definition.
How does filler help?
Hyaluronic acid (HA) filler is injected into the groove and under the mouth corners to restore volume and support. It softens the line, lifts the mouth corners slightly and can make the face look more relaxed. Results are immediate, downtime is short, and HA filler usually lasts about 6 to 12 months in this moving area. It can be dissolved if needed.
How do thread lifts and filler compare for marionette lines?
- Main action: threads lift sagging tissue; filler fills the groove.
- Best for: threads when jowls cause the line; filler when hollowness causes it.
- Results: both visible right away.
- Downtime: threads one to two weeks of swelling or tightness; filler a few days of mild swelling.
- How long it lasts: threads often one to two years; filler about 6 to 12 months here.
When are threads the better choice?
Threads are often better when you see clear jowls and the line deepens because tissue hangs over it. Lifting the lower face can improve both the marionette lines and the jawline at once. People in their 40s and 50s often benefit most.
When is filler the better choice?
Filler is often better when the lines are mainly hollow grooves with little sagging, or when the mouth corners turn down. A small amount can make a clear difference with very little downtime, which suits visitors on short trips.
Can Botox help too?
Yes. A small dose of Botox in the DAO muscle can relax the pull on the mouth corners, so they sit higher. It is often used together with filler or threads for a softer, happier look. The effect lasts about three to four months.
Can you combine treatments?
Yes. A balanced plan may use threads to lift the jowls, filler to support the mouth corners and Botox to relax the downward pull. Ultherapy or Thermage may be added to tighten the skin. Your doctor will plan the order and spacing.
Is it safe?
Both treatments are safe when done by trained doctors. Thread risks include bruising, swelling, asymmetry and visible threads. Filler risks include bruising, lumps and, rarely, blocked blood vessels. The area around the mouth moves a lot, so careful placement matters.
How to decide
Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare. Lower-face lines are a frequent concern among visitors. The right plan depends on whether sagging, volume loss or muscle pull shapes your lines.
Frequently asked questions
Can filler alone fix marionette lines?
For mild lines, often yes. Deeper lines with sagging usually need lifting too.
Do threads hurt around the mouth?
The area is numbed. Expect some tightness and soreness for several days.
How long does filler last around the mouth?
Usually about 6 to 12 months, as the area moves a lot.
Can I have filler and Botox on the same day?
Yes, this is common.
