Those Ponyo-like bulges on the sides of your mouth—what are they, and what causes them?
Those "puffy spots" next to your mouth that catch your eye every time you look in the mirror. First, let's take a look at what these puffy spots are and what causes them.
Why Do "Ponyo" Lines Form Around the Mouth? The 5 Main Causes
"Ponyo on the sides of the mouth" is not a formal medical term, but rather a colloquial term referring to the soft tissue that bulges out plumply from the corners of the mouth to the lower jaw. The following five factors are considered the main causes of this bulge that appears on the sides of the mouth.
・ Skin laxity and sagging due to aging
Collagen and elastin, which help maintain skin elasticity, decrease with age.This causes changes around the mouth. Additionally, loosening of the SMAS fascia—which supports the skin and fat—and the structures around the “modiolus,” where multiple facial muscles converge, leads to changes around the mouth.
・ Sagging or accumulation of fat
The main cause of fullness around the mouth is a type of fat called “jowl fat,” located on either side of the corners of the mouth.As we age, the fat in the upper cheeks—known as “malar fat”—begins to sagThis happens. Additionally, as the position of the deep-seated fat—known as “buccal fat”—changes, this fat accumulates around the mouth, resulting in a chubby appearance.
・ Changes in the Skeletal Structure
As we age, some of the facial bones shrink.When "bone atrophy" occurs, the foundation that supports the skin and fat shrinks,This happens. As a result, excess skin and fat tend to accumulate around the mouth.
・ Muscle Weakness and Habits
If you unconsciously pucker your lips or let the corners of your mouth droop, or if you lead a lifestyle where you rarely move your mouth, your facial muscles will weaken and become unable to support the skin and fat. Also, if you have habits such as clenching your teeth or chewing on one side only,When certain muscles become overly developed, it can easily throw off the balance of the face and contribute to a fuller appearance.The following is a list of the items that we will make available to you.
・ Poor posture
Poor posture, such as a hunched back or a straight neck, is believed to be one factor that pulls the facial muscles downward. When you maintain a posture in which your lower jaw juts forward, the skin and muscles around your mouth are pulled downward as a result. Consequently,Poor blood circulation causes swelling, which in turn accelerates the sagging of fat.The first is the
Reasons Why a Self-Care Approach Is Difficult
It’s not easy to treat jowls with self-care alone. The root cause of the changes lies in the deeper layers of the skin, andSelf-care alone is often insufficient to address the loosening of the SMAS fascia, which supports the skin and fat.It is.
In addition, improper self-massage or facial muscle exercises can cause friction and may worsen the condition. Therefore, to ensure the best possible results, why not consider seeking professional care at a clinic?
