2025.2.26
Many people may be concerned about the downward turn of their mouth corners as they age, giving their expression a darker appearance.
In fact, there are several causes for the appearance of downward mouth corners, and by applying the appropriate treatments, you can naturally lift the corners and regain a brighter, more youthful impression.
In this article, Dr. Shunsuke Nagura, Japan’s top aesthetic surgeon with numerous accomplishments, will explain in detail the causes of downward mouth corners and effective treatments. If you're troubled by looking older, please read until the end.
First, we will introduce the case of Dr. Nagura, a famous liposuction doctor.
CASE 01
In their 20s

【Case explanation]】The face line was sluggish due to buccal fat. By removing fat, my skin becomes less sagging and has a beautiful contour no matter which direction it wraps around.
CASE 02
In their 30s

【Case explanation】 People whose lower cheekbones appear sunken. By injecting the harvested fat into the cheeks, a beautiful contour with no dents was created. The fat under my chin has also been reduced.
CASE 03
In their 40s

【Case explanation】 People who have fat on the side of their mouth that makes their outline look square. By removing fat from the sides of the mouth, the contours have changed to a feminine one. Also, by removing the fat under the chin, the face line from an angle became more beautiful.
CASE 04
In their 50s

【Case description】 A patient had fat in his cheeks and under his chin, making his face look round. By taking the appropriate amount of fat, you can maintain a rounded shape while creating a clean contour.
CASE 05
In their 60s

【Case explanation】 When you look at it from the front, it doesn't look like there's a lot of fat, but when you look at it from an angle, you can see that there is fat. The sagging area under the chin due to age has been transformed into a more youthful face by removing fat and lifting it with a thread lift.

1. What are the main causes of downward mouth corners?
POINT 01
Causes of downward mouth corners and the factors behind them

Main causes of downward mouth corners:
・Marionette lines (shadows around the mouth): Aging causes shadows to form around the mouth, making the corners appear to drop.
・Influence of jowl fat: When there is excess fat around the mouth, the weight can cause the corners to droop.
・Muscle influence: Strong activity of muscles like the "depressor anguli oris" can pull the corners of the mouth inward.
As you can see, there are various factors involved in the drooping of the mouth corners, so choosing the right treatment is crucial.
2. Options for Lifting the Corners of the Mouth
POINT 01
Optimal treatments for lifting the corners of the mouth

① Mouth corner lifting (mouth corner incision)
This surgery directly lifts the corners of the mouth, providing immediate results. However, it has limited applicability, so it needs to be chosen carefully.
② Fat removal (liposuction)
Reducing jowl fat, which causes shadows around the mouth, can provide a natural lifting effect.
③ Lift-up procedures
Combining thread lifts and facelifts can improve the downward turn caused by sagging skin.
Among these, fat removal and lift-up procedures are recommended for those seeking a more natural result.
3. Removing Shadows for a Naturally Youthful Look
POINT 01
Eliminate shadows around the mouth to achieve natural rejuvenation

For example, dark shadows around the mouth can give the impression of a drooping mouth even without sagging.
A method to reduce these shadows is a treatment that appropriately removes fat.
In particular, jowl fat liposuction can eliminate excess fat around the mouth, removing the shadow and lifting the corners naturally.
Dr. Nagura has an overwhelming record as the national No.1 for jowl fat removal surgeries for 7 consecutive years.
4. Benefits and Risks of the Procedure
POINT 01
Key points of jowl fat removal
・Natural results
・Brighter appearance around the mouth
・Relatively short downtime (most bruising disappears within 1-2 weeks)
【Risks】
・Limited applicability for some patients
・May require combining with other procedures
5. Safe Treatments by an Aesthetic Surgeon Specialist
POINT 01
Trustworthy treatment by Dr. Nagura
Furthermore, many surgeons are reluctant to operate on their own family members, but Dr. Nagura has performed surgery on his own mother as well as staff members, demonstrating his trust and exceptional skill. He is also trusted by many doctors as a technical instructor.
Dr. Nagura’s treatments are not just about lifting the corners of the mouth; he recommends "appropriate methods based on the cause." He will only suggest treatments that truly promise results and will communicate clearly if a procedure is unnecessary. This approach is one of the reasons why so many patients choose him.
6. Conclusion
POINT 01
Choosing the best treatment and doctor

If you're unsure about which procedure to choose, feel free to consult with Dr. Nagura, who has abundant experience in fat removal and lift-up procedures.
