Safe Facial Filler Access Standards in Korea for the “Peanut-Shaped Face” | GIRIN Plastic Surgery

Structural hollowing of the temples and cheeks creates the characteristic peanut-shaped facial contour.

Causes of the “Peanut-Shaped Face” and Facial Filler Access Standards of GIRIN Plastic Surgery

When taking standard reference photos for the “Safe Facial Filler Guidelines in Korea,”
have you ever felt concerned that your facial contour looks uneven and wavy rather than smooth?
Or have you ever felt that prominent cheekbones make your face appear thinner and more deeply hollow because there is little cheek volume?
This “sunken” or “hollowed” appearance often makes many people feel that they look tired and that their facial structure appears increasingly unbalanced.

However, changes in facial shape like these are, in many cases, not caused solely by “poor care,”
but by multiple overlapping factors such as the distribution of facial fat (fat compartments),
and age-related volume changes that occur step by step, as well as differences in skin condition and bone structure among individuals.

In Korea, changes in the facial contour that occur together due to “temple hollowing” and “sunken or hollow lateral cheeks”
are commonly referred to as a “peanut-shaped face.”
In this article, we will explain the causes of the peanut-shaped face and describe in detail the conceptual standards for facial filler treatment at GIRIN Plastic Surgery.

Limitations of Correcting the “Peanut-Shaped Face” with Hairstyles and Makeup

Recently, content introducing the use of hairstyles and makeup to help “conceal” a peanut-shaped face has received significant attention,
because these methods can be applied immediately and may show visual effects from certain angles.

However, the important point is that these methods are not complete solutions,
and therefore may not be sufficient for those seeking clear changes in facial structure and volume.
In cases where precise and noticeable improvement is desired, satisfaction may be limited due to these ongoing constraints.

Effects of Gua Sha Depending on Skin Elasticity and Bone Structure

Gua Sha tools come in a wide variety of sizes and shapes and have been widely discussed in recent years,
with many celebrities even using them as part of their daily routines, leading to widespread purchase and use.

One reason for this popularity is the desire to “refine facial contours” and the wish to make uneven facial lines appear smoother,
with many people using Gua Sha in hopes of reducing protrusions and depressions and achieving a more even-looking face.

When used correctly, Gua Sha may help with lymphatic circulation, swelling management, and relieving sensations of facial heaviness or puffiness,
but limitations may arise if skin elasticity has significantly decreased, if there is insufficient understanding of proper direction, pressure, and frequency of use,
or if the facial bone structure is already prominent.

In addition, incorrect use may instead accentuate skin stretching or sagging,
so it is important to pay close attention to proper usage methods and to control the duration of use appropriately.

If Surgery Feels Burdensome: Non-Surgical Methods to Improve the Peanut-Shaped Face

Prominent cheekbones combined with reduced cheek volume can make the face appear hollow and fatigued.

If you feel that “surgery is frightening” or that you “want a natural-looking restoration,”
many people begin to consider aesthetic procedures to improve a peanut-shaped face.

Non-surgical options commonly used to help correct uneven or irregular facial contours include
lifting devices, thread lifting, botulinum toxin injections, and dermal fillers.

Causes of Sunken Cheeks: Why Does the Peanut-Shaped Face Occur?

Age-related facial volume loss occurs gradually and affects specific fat compartments of the face.

Congenital Causes: Influence of Bone Structure

Overall, the peanut-shaped face can be explained as resulting from two main causes.
One congenital cause is a prominently developed bone structure, such as pronounced cheekbones or a square jaw.

Acquired Causes: Volume Loss Due to Aging

The most significant acquired cause is aging.
As age increases, facial fat gradually atrophies, collagen decreases, and skin elasticity declines accordingly,
causing the volume in the central area of the face to decrease and become hollow first.

Especially in individuals with prominent facial bones, the cheekbone and jaw areas have a higher proportion of bone and muscle compared to fat,
resulting in less volume change than in other areas.
As the aging process progresses, this makes it easier for the face to transition into a “skeletal” appearance or a peanut-shaped face.

Why the Face Feels Different After Orthodontic Treatment

Another acquired factor is change following orthodontic treatment.
In many cases, this does not mean that the facial bones themselves have changed,
but rather that changes in dental alignment alter the way the masticatory muscles are used,
ultimately changing overall facial muscle usage patterns.

During this process, an appearance resembling “sunken or hollow cheeks” may occur,
and if facial volume was already limited, this condition can become more pronounced,
leading individuals to feel that their face has changed into a peanut-shaped face.

Could My Face Also Be Peanut-Shaped? Structural Checkpoints

If several of the following points apply to you, it may be worth considering the possibility of structural volume imbalance,
which can cause the face to be perceived as peanut-shaped.

  • The facial contour appears more emphasized in photographs than when looking in the mirror
  • Persistent shadowing is observed in the lateral cheek area
  • After weight loss, the facial outline appears unbalanced or disproportionate
  • The temple area appears sunken or hollow
  • You are often told that you look tired or older than your age

※ These points are provided for informational purposes only and are not intended for diagnostic use.

Even a Small Face Can Have Concerns: The Importance of Volume and Three-Dimensionality

When bone structure remains prominent while soft tissue volume decreases, facial imbalance becomes more noticeable.

Many people assume that being born with a small face means having no concerns,
but in reality, the face requires balance not only in bone structure,
but also in overall size, volume, and three-dimensionality.

Concerns related to facial empty space, asymmetry, and line definition can overlap,
which is why both frontal facial lines and side-view volume are extremely important.

When these curves and contours are properly balanced,
facial features such as the eyes, nose, and lips become more defined even from the front,
and a visual effect that makes the face appear smaller may also be achieved.

The Core of Facial Improvement: Temples, Cheekbones, and Lateral Cheeks

To improve a peanut-shaped face, it is essential to focus on three key lines:
the temples, the cheekbones, and the lateral cheeks.

Except in cases of inherently prominent cheekbones or structurally sunken temples,
the peanut-shaped face is often a typical form of age-related change.
As age increases, the lower jaw becomes affected by gravity.

As a result, deep fat layers gradually decrease, creating hollowed areas,
and because the lateral cheek is a space without bony support, the hollowing becomes particularly noticeable.

If the temples are also deeply sunken and cheek fat is minimal,
the masseter and temporalis muscles become more prominent, making the facial line appear uneven,
leading many people to use photo editing or retouching apps to compensate for these irregular lines.

Impression Changes Caused by Temple Hollowing and Lateral Cheek Depression

Gua Sha may help with temporary swelling but has limitations in addressing structural volume loss.

A defining characteristic of the peanut-shaped face is that the temples and lateral cheeks appear sunken.
Even a small decrease in volume in these areas can make the overall appearance look tired or worn.

Therefore, it is necessary to accurately identify the cause through palpation,
assessing skin tissue tension, the degree of volume loss, and the true source of the change,
in order to reasonably expect an “oval face” effect.

Concerns That Commonly Appear Together: Nasolabial Folds

A common concern that accompanies the peanut-shaped face is nasolabial folds.
While there are various causes, one characteristic is that sagging under-eye fat deepens the fold,
although some individuals have this feature due to their natural bone structure.

By adding volume to the anterior cheek while finely adjusting the depressed areas of the nasolabial folds,
it is possible to reduce a tired or aged appearance.

Fillers Used for Facial Contour Improvement and Differences from Other Procedures

Non-surgical facial treatments focus on restoring balance rather than simply adding volume.

Characteristics of Hyaluronic Acid Fillers

Fillers used for facial contour improvement are most commonly hyaluronic acid fillers,
which are characterized by immediate results and the ability to make fine adjustments.

Because they allow precise line correction,
they can be used for everything from small areas such as fine wrinkles
to broader volume adjustments such as the cheeks and forehead.

Comparison with Autologous Fat Grafting

Another method for correcting facial volume is autologous fat grafting,
but for those seeking convenient, non-surgical improvement,
the need for a surgical process and fat harvesting from the abdomen or thighs can be burdensome.

Real Patient Case

Evaluating the temples, cheekbones, and lateral cheeks together is essential for facial contour analysis.

This is a case of a patient who initially considered facial contour surgery.
The patient had long been concerned about reduction surgery because prominent cheekbones made the face look uneven and wavy.

However, upon evaluation, the patient’s face was actually very small,
and rather than having large cheekbones, the issue was more pronounced hollowing in the lateral temple area.
The patient originally had a face close to an oval shape, but upon entering the late twenties,
loss of cheek fat and decreased elasticity made the cheekbones appear more prominent.

Changes after orthodontic treatment often result from altered muscle usage rather than bone structure changes.

Aging often causes volume loss in specific areas, which in turn affects the overall facial shape.
When examining the face from the front, side, and oblique angles,
lateral cheek hollowing and cheek sagging were evident, resulting in deeper nasolabial folds.

The patient had also recently undergone dieting, which was judged to have had a clear impact,
and this factor was considered during treatment.
It is clarified that the photos presented are actual filler treatment photos with no retouching whatsoever.

Timeline of Changes After Filler Treatment

Nasolabial folds frequently deepen when midface and cheek volume decreases.

  • Immediately after treatment: visible volume, temporary swelling
  • 3–7 days: line refinement begins
  • 2–4 weeks: facial shape stabilizes

After filler treatment, immediate changes are observed, and over time the result gradually settles naturally.
Therefore, rather than judging the outcome based solely on the immediate post-treatment appearance,
it is necessary to consider the stabilization period of approximately 2–4 weeks.

The Most Important Principle in Facial Filler Treatment

Hyaluronic acid fillers allow precise volume adjustment for facial contour refinement.

For peanut-shaped faces with pronounced cheek hollowing and depression, excessive injection must be avoided.
If too much filler is injected, it may be displaced or migrate,
causing the outer edges to appear protruded rather than refining the facial contour.

This can make the facial outline look thicker, further emphasize cheekbone prominence,
and lead to the opposite effect of making the face appear larger.
Therefore, using a micro cannula and injecting accurately into the correct layer is critically important.

Other factors must also be considered, including light reflection, overall facial contour lines, anterior volume, lateral volume,
as well as minimizing the risk of vascular injury.

Side Effects and Precautions of Filler Treatment

Possible side effects of facial filler treatment include mild swelling and bruising.
If depth control is inadequate, a Tyndall effect may occur,
which causes the treated area to appear bluish and typically occurs when the filler is injected too superficially.

In addition, incorrect injection may lead to complications such as vascular compression or overcorrection,
and treatment outcomes may vary depending on individual differences.

After petit procedures, bruising, redness, infection, pain, and swelling may occur.
If you are pregnant, breastfeeding, have diabetes, have a tendency toward keloid scarring,
or are taking medication for related conditions, there may be restrictions on treatment,
so consultation with a qualified medical professional is required prior to treatment.

Frequently Asked Questions During Consultation (Q&A)

This image shows an actual filler treatment result without any photo retouching.

Q1. Why does a peanut-shaped face appear more pronounced in photographs?

One common complaint among people with peanut-shaped faces is that “the face looks stranger in photos than in the mirror.”
This phenomenon is related to facial three-dimensionality and volume distribution.

Cheekbones and lateral cheek contours that are not very noticeable when viewed directly
become compressed into a flatter image through a camera lens, making protruding areas appear more prominent
and hollow areas appear deeper, creating an optical illusion.
When volume in the central face and lateral cheeks is reduced, cheekbone prominence becomes even more emphasized in photographs.

Q2. Can the face become peanut-shaped even without weight loss?

This is entirely possible, because the peanut-shaped face is more closely related to changes in the position and atrophy of facial fat than to body weight changes.

As age increases, facial fat does not decrease evenly, but tends to diminish first in specific areas.
The lateral cheeks and central face are particularly sensitive to aging, so volume may appear reduced even if body weight remains the same.
In contrast, the cheekbone area has a higher proportion of bone and muscle, resulting in less change and making the facial contour appear more uneven overall.

Q3. Can Gua Sha or facial massage improve a peanut-shaped face?

Gua Sha or lymphatic massage may help temporarily reduce swelling and improve blood circulation,
but if volume has already decreased or skin elasticity has declined, continued physical stimulation may instead promote skin stretching or sagging.

In cases where the core issue of a peanut-shaped face is volume deficiency and structural imbalance,
massage alone makes it difficult to expect fundamental improvement,
and an approach tailored to the current facial condition is required.

Q4. After orthodontic treatment, the face feels different. Did the bones actually change?

In most cases, orthodontic treatment does not significantly alter facial bone structure,
but changes in masticatory muscle usage patterns may make pre-existing volume deficiencies or imbalances more noticeable.

Q5. Does a peanut-shaped face always require filler treatment?

Not necessarily. Having a peanut-shaped face does not mean that filler treatment is required in all cases.
It is first necessary to analyze whether the main cause is cheekbone structure, volume atrophy, or a combination of both.

In some cases, priority may be given to reducing protruding structures before considering filler treatment.

Q6. What is the most important point when improving a peanut-shaped face with fillers?

The most important point is not “how much is filled,” but “where and along what flow the volume is supplemented.”
Simply filling the hollowed areas may instead make the cheekbones appear more prominent.

Therefore, it is essential to design treatment with consideration of three-dimensional balance from the front, side, and oblique views,
and to naturally connect the line from the cheekbones to the jawline with the lateral cheek as the central axis,
which is the key to creating a softer and more youthful appearance.

Q7. How long do fillers last?

Fillers are not permanent treatments, and their duration varies depending on the type of filler used and the individual’s metabolic rate.
Generally, results may last from several months up to approximately one to two years in some cases.

As fillers are gradually absorbed over time, maintenance or repeat treatments may be required to sustain results.

Q8. How should one choose a clinic?

GIRIN Plastic Surgery analyzes the temples, lateral cheeks, and anterior cheeks as a single continuous line,
and before filler injection, carefully checks facial balance from the front, side, and oblique angles,
adhering to a conservative design principle that avoids excessive injection beyond what is necessary.

Procedures That Preserve Each Individual’s Unique Charm



Proper volume distribution can create a softer oval-face impression while maintaining natural facial features.

The peanut-shaped face has overall curved lines and three-dimensionality, with emphasized cheekbones and a sharper-looking chin.
Shadows easily form along the lateral cheekbones, leading many people to feel that they “must fill everything in,”
but this line is not inherently negative and can become an attractive point that reflects each individual’s unique atmosphere.

However, if you are dissatisfied with your facial shape, if it has become a complex,
if unintended cheek hollowing occurred due to rapid weight loss,
or if you desire a softer, more lively, and more youthful impression,
filler treatment can offer the potential for an “oval face” effect.

It is often said that the face is a mirror that reflects the mind, as much of our nonverbal communication is conveyed through the face.
Because of this, the face plays a very important role.
By caring for the outward appearance while also attending to one’s inner state,
I believe it is possible to achieve a truly beautiful face.
