When the corners of the mouth appear to droop or the lines below them become deeper, your overall appearance may look different.
Even when you are not smiling, you may look tired, or your neutral expression may appear somber.

The lines around the mouth and marionette lines are common concerns in this situation.
Marionette lines refer to the lines that extend downward from the corners of the mouth toward the chin.
This is often not simply a matter of wrinkles forming in the skin. A combination of insufficient volume, reduced skin elasticity, sagging, and muscle movement may be involved.
Today, from the perspective of youthful facial rejuvenation, we will review the causes of lines around the mouth and marionette lines, as well as the differences between fillers, skin boosters, thread lifting, Botox, and facelifts.
- Lines Around the Mouth May Not Be Only a Skin Problem

The area around the mouth moves frequently when we speak, smile, and chew.
When reduced skin elasticity is added to these repeated movements, fine lines can become more noticeable.
As we age, the fat volume around the cheeks and mouth may decrease or shift downward, making the area around the corners of the mouth appear hollow.
This can create a shadow below the mouth, making the marionette lines look deeper.
The approach should vary depending on whether hollowness, skin aging, sagging, or muscle activity is the main contributing factor to the lines around the mouth.
- Consider Fillers When the Area Below the Corners of the Mouth Looks Hollow
Fillers may be considered when the area around the mouth appears hollow or when the marionette lines look indented like grooves.
They work by restoring deficient volume, softening shadows, and helping the lines below the corners of the mouth appear less deep.
One advantage is that volume changes can be seen relatively quickly.
However, placing too much filler in a face with significant sagging may make the area around the mouth look heavy.
Fillers are more suitable when hollowness is the main concern rather than sagging.

- Consider Skin Boosters for Fine Lines Spread Across the Skin
If fine lines, dryness, and reduced skin texture are more noticeable than deep indentations around the mouth, skin boosters may be considered.
Rather than directly filling hollow areas, skin boosters are more focused on managing the condition and elasticity of the skin.
They may be helpful when the skin around the mouth looks thin and dry or when multiple layers of fine lines are visible.
They may also be considered by those who want a natural-looking youthful facial rejuvenation treatment but find the volume created by fillers burdensome.

- Thread Lifting May Be More Suitable for Cheek Fat That Has Shifted Downward
If marionette lines have developed as the cheek fat and tissues around the mouth have shifted downward, thread lifting may be considered.
Thread lifting uses medical threads to help guide sagging tissue in a more lifted direction.
It may help refine the contours when shadows below the mouth, fullness in the deep cheeks, and sagging along the jawline appear together.
While fillers focus on filling hollow areas, thread lifting focuses on lifting tissue that has shifted downward.
However, if sagging is significant or the skin is very thin, thread lifting alone may have limitations.
- Botox Can Help Control the Muscular Force That Pulls Down the Corners of the Mouth

Muscle activity can also contribute to the corners of the mouth appearing to droop downward.
If the muscles that pull the corners of the mouth downward are strong, the area may look drooped even when the face is expressionless.
In such cases, Botox may be considered to help control excessive movement of the muscles around the mouth.
Botox does not add volume or tighten the skin.
Its focus is on reducing the overly heavy appearance of the expression when muscle-related drooping around the mouth is present.
- Consider a Facelift for Deepened Marionette Lines
When lines around the mouth and marionette lines have been present for a long time and have become deep, a facelift may also need to be considered.
A facelift is a surgical procedure that addresses not only the skin but also sagging facial tissues and changes in the jawline.
If cheek sagging, fullness in the deep cheeks, and loss of jawline definition are pronounced, fillers or Botox alone may produce limited changes.
Although the recovery period and surgical plan need to be considered carefully, if the cause of the sagging lies in deeper layers, a facelift may be considered as a more structural approach to youthful facial rejuvenation.
In Summary
Lines around the mouth and marionette lines are areas where it can be difficult to decide based on the name of just one procedure.
First, it is necessary to distinguish whether to restore lost volume, lift sagging tissue, or control muscle movement.
If you are considering youthful facial rejuvenation, rather than looking only at the depth of the wrinkles, it is advisable to check whether the clinic evaluates the volume around the mouth, skin elasticity, direction of sagging, and facial expression muscles together.
