Peanut-shaped face: How much can filler improve it? From the principles of volume to safety

The term "peanut-shaped face" has been heard much more frequently in consultation rooms lately. It refers to an impression where the temples and side cheeks are slightly sunken when viewed from the front, and the cheekbones and lower face are relatively prominent, making the center of the face look slender. In fact, this is not an official medical diagnosis, but a general term in the beauty industry that visually describes a combination of cheek volume loss, relative protrusion of the cheekbones, and sagging cheeks.

Starting with the conclusion, this impression can be smoothed out to a large extent with fillers. The key point is that it is not about shaving the cheekbones, but rather the principle of 'volume redistribution' to reduce the gap with the areas that look protruded by filling in the sunken areas. It is an approach of gently connecting the surrounding areas, rather than removing the protruding parts.

🥜 What exactly is a peanut-shaped face?

A peanut-shaped face is closer to a state where the map of volume has been disrupted, rather than being a problem with a specific bone of the face. As aging progresses, SOOF (sub-orbicularis oculi fat) and cheek fat atrophy and move downward, resulting in a loss of mid-face volume.

Here, the visually most decisive area is the **midcheek groove (buccal depression)**. This sunken groove right beneath the cheekbones creates shadows, making the face look slender. Therefore, how to handle this section becomes the key to improving the impression.

One point to note. The approach completely differs depending on whether the cause is volume loss, skeletal cheekbone protrusion, or sagging skin. If the skeletal structure itself is prominent, there is a limit to using only filling procedures, and if sagging is the primary cause, you should consider elasticity and lifting first rather than volume.

📌 Key Summary: The peanut-shape is not a diagnosis name but an impression where volume loss, relative cheekbone protrusion, and sagging overlap, and identifying the cause determines the direction of the procedure.

💉 By what principle do fillers smooth out lines?

Fillers are a filling procedure. It is not about physically reducing the cheekbones, but a method of mitigating the relative feeling of protrusion by complementing the sunken temples and cheeks. It is similar to filling in the low parts of an uneven road to make the whole thing flat.

The most widely used ingredient is hyaluronic acid (HA) filler. Because it is based on ingredients originally present in our body, it is familiar, and above all, its reversibility, allowing it to be dissolved again with an enzyme called hyaluronidase, is a major advantage. This means there is room to undo it when you do not like the result or need an adjustment.

There are a few more ingredient options.

CaHA has high support, but it cannot be dissolved like HA, so caution is needed in choosing indications, and PLLA is a collagen booster concept that slowly improves as collagen fills up over several weeks to months, rather than providing immediate volume. If it is the first procedure, it is often approached with HA, which leaves room for adjustment.

📌 Key Summary: Fillers are a redistribution of volume that reduces the gap by filling in sunken areas, and HA, which can be reversed, is frequently chosen for the first procedure.

📍 Which areas are they injected into?

There are largely three areas touched during peanut-shape correction.

• Temples (Temporal area): The key area that naturally connects the forehead and cheekbone lines. However, the difficulty is high because blood vessels and nerves are densely populated.

• Front Cheeks · Mid-face: The center of cheek volume loss. It removes shadows and revives a bright impression.

• Side Cheeks · Sunken areas under the cheekbones (midcheek groove): The visual key area that makes the face look slender.

Depending on the case, the tip of the chin may also be complemented to match the overall balance.

The dosage varies widely depending on the degree of depression. Generally, temples are treated within the range of 1 to 6 cc combined for both sides, and cheeks/side cheeks within 0.5 to 2 cc per side (around 1 to 4 cc combined for both sides). However, what is more important than numbers is a small-dose, step-by-step approach. Putting in too much at once can make the face look wider or bloated, so it is more natural to divide it and fill it while watching the reaction.

📌 Key Summary: Temples, front cheeks, and midcheek grooves are the key areas, and although dosage varies greatly by individual, a small-dose, step-by-step approach is natural.

⏳ How long does the effect last, and can it be reversed?

The duration of HA fillers is usually 6 to 18 months. The difference is large depending on the type of product, injection area, and individual metabolic rate. Areas with a lot of movement tend to absorb relatively faster.

When adjustment is needed, HA fillers can be dissolved with hyaluronidase. The fact that it can be reverted when asymmetry occurs or when it differs from the desired line is also psychologically reassuring. Conversely, CaHA, PLLA, and autologous fat grafts are difficult to dissolve in this manner.

If you are someone with large weight fluctuations, there is something to note. In the case of facial hollows due to dieting, repeated weight gain and loss may lead to unstable retention of results, so it is better to plan after weight has stabilized to some extent.

📌 Key Summary: HA fillers last 6 to 18 months, and since they can be dissolved and adjusted with enzymes, there is room to reverse them.

⚠️ Safety, what should be verified?

As fillers are a filling procedure, the most important thing is where and how they are injected. In particular, because blood vessels and nerves are densely populated in the temples, around the eyes, and around the nose, the practitioner's proficiency in facial vascular anatomy is directly related to safety.

The situation that requires the most caution is vascular embolization/occlusion. Although rare, it is a serious situation, so if the following signals appear, you must contact the clinic where you received the procedure without delay.

• Paleness/blue discoloration of the skin, mottled livedo reticularis

• Severe pain that goes beyond the injection site

• Vision abnormalities, sudden headache, or neurological symptoms

So, there is something that must be checked during consultation. Whether the institution performing the procedure is equipped with hyaluronidase and has emergency response systems in place. Since these are essential conditions for adjustment and emergency response.

One practical tip. If you record the name of the product, dosage, area, and date of the procedure, it will serve as a basis for future adjustments or repeated procedures. When performing repeated injections, it is good to manage accumulation by referring to prior history.

If you are pregnant or breastfeeding, cosmetic fillers are generally not recommended, so we advise postponing the procedure during this period and consulting with medical staff first.

📌 Key Summary: High-risk areas depend heavily on anatomical proficiency, and having hyaluronidase equipped and recognizing emergency signals are essential safety conditions.

🔄 When fillers alone are not enough? Combined/Alternative approaches

Because the causes of a peanut-shaped face are complex, there are cases where volume alone cannot solve everything. In such cases, approaches are combined.

• When sagging is accompanied: If the impression is sunken as the cheeks sag downward, there is a limit with volume alone. At Onlif Clinic, we prioritize catching elasticity through non-surgical liftings such as All-Tight Lifting, thread lifting, ultrasound HIFU/high-frequency RF, and consider a sequence of supplementing volume with fillers if necessary.

• When the lower face looks wide due to developed masseter muscles: Combining jaw (masseter) Botox can enhance the contouring effect.

• If accompanied by decreased skin texture and elasticity: There is also a way to smooth out the skin's texture and hydration itself by adding skin boosters.

If the range of volume loss is very wide, autologous fat grafting is sometimes discussed. However, this is a surgical process rather than a filler, and has the characteristic that the engraftment rate is difficult to predict. **When skeletal cheekbone protrusion is the main cause, malar osteotomy (zygoma reduction surgery)** is mentioned as a suitable alternative, but such surgical methods are a separate field where indications are clearly distinguished. The direction that Onlif Clinic proposes first is solely an approach of naturally smoothing out texture through non-surgical procedures from a dermatological perspective.

For reference, even when cheeks are excessively sunken after buccal fat removal, it can be complemented with fillers, but because deciding the location and dosage is tricky, a precise plan is required.

Onlif's perspective is not on changing the shape. Organizing the imbalance of volume that hides natural beauty and reviving it without going overboard. This is also why we assign procedures that are performed best in each field under the philosophy that "one doctor cannot do everything well."

📌 Key Summary: If sagging, masseter muscles, and skin texture overlap, liftings, Botox, and skin boosters are combined, and Onlif prioritizes non-surgical improvements.

🗓️ Post-procedure recovery and evaluation of results

Post-procedure swelling and bruising usually improve within 3 to 14 days. Volume may look somewhat excessive in the beginning, which is because it is in a state mixed with swelling.

Therefore, evaluating the final results is appropriate at 2 to 4 weeks after the swelling has stabilized. If you compare photos from various angles such as front, 45 degrees, and side at this time, you can read the changes much more accurately than simply looking in the mirror.

If adjustments are needed, it is better to proceed after this evaluation. Making a hasty judgment while swelling remains can lead to unnecessary additional procedures.

📌 Key Summary: Swelling and bruising improve within 3 to 14 days, and judging and adjusting the results is appropriate after 2 to 4 weeks with photos from multiple angles.

❓ Frequently Asked Questions (FAQ)

Can fillers reduce cheekbones?

No. Fillers are not a procedure to reduce bones, but a volume redistribution method that mitigates the relative feeling of protrusion by filling in the sunken surrounding areas. If skeletal protrusion is the main cause, there is a limit with filling procedures alone.

Does getting fillers make your face look bigger?

It can if you put in too much at once. Therefore, an approach of dividing into small amounts and applying step-by-step while watching the reaction is advantageous for creating natural lines.

How long does the effect last?

Based on HA fillers, it is usually 6 to 18 months. The gap is large depending on the product type, injection site, and individual metabolic rate.

Can I reverse it if I don't like it?

HA fillers can be adjusted or removed by dissolving with an enzyme called hyaluronidase. This reversibility is a huge advantage of HA.

Are temple fillers safe?

Since the temple is an area where blood vessels and nerves are concentrated, the anatomical proficiency of the practitioner is especially important. Proceeding in a place equipped with hyaluronidase and an emergency response system is a safety condition.

What symptoms should I contact immediately after the procedure?

Skin paleness/blue discoloration, livedo reticularis, severe pain, vision abnormalities, sudden headache or neurological symptoms can be emergency signals of vascular occlusion, so you must contact medical staff immediately.

Is it possible to receive the procedure during pregnancy or breastfeeding?

Cosmetic fillers are generally not recommended during this period. We advise you to postpone the procedure and definitely consult with medical staff first.

Can sunken cheeks after cheek fat removal also be filled?

Cheeks that are excessively sunken after buccal fat removal can be supplemented with fillers. However, because determining the location and dosage is tricky, individual examination and a precise plan are required.

The cause of a peanut-shaped face varies from person to person, so even if they look like the same impression, the solution is different for each. Depending on whether it is volume loss, sagging, or prominent skeletal structure, filler alone may be correct, or lifting and Botox may need to be considered together. Accurate differentiation of cause and direction of treatment require diagnosis by looking at the face in person. Gangnam Onlif Clinic contemplates together in direction of reviving natural texture and balance rather than changing the shape.
