Hollow cheeks and nasolabial folds are often mentioned together, but they are different areas and may have different causes. Hollow cheeks refers to the mid-cheek area or the area beneath the cheekbone looking sunken, while a nasolabial fold is the crease running from the side of the nose down toward the corner of the mouth. Choosing a treatment approach should therefore start with assessing facial structure, fat distribution, skin elasticity, and treatment history — not choosing a procedure based on the name of the concern alone.
This article is general information. It cannot be used to diagnose or determine a product amount in place of an in-person doctor assessment.
What Is Cheek Hollowing, and What Does It Look Like
ลักษณะและสาเหตุของแก้มตอบที่พบได้บ่อย
"Hollow cheeks" is a descriptive term, not a fixed diagnostic category. It generally refers to the mid or lateral cheek area looking sunken, flat, or casting a more prominent shadow beneath the cheekbone. Several factors may contribute together:
- Natural facial structure or fat distribution: some people have a relatively hollow mid-cheek area from a young age
- Loss of tissue volume: increasing age, significant weight loss, or changes in facial fat and structure
- Laxity and shadowing from light: tissue that has shifted position can create a shadow resembling hollow cheeks, even when volume has not fully disappeared
- Asymmetry or the result of previous treatment: natural differences between the two sides of the face, or previously injected material, can affect the visible shape
The doctor should assess the face from multiple angles, both at rest and while moving, to distinguish whether the main issue is volume, skin laxity, or shadowing.
What Can Cheek Filler Do, and What Are Its Benefits
Hyaluronic acid (HA) filler is a gel the doctor may consider using to add or support volume in a specific area, when it matches the facial structure and the product's approved use. The goal may be to reduce some of the hollowing, balance proportions, or make the cheek line look more blended. The result depends on the product, technique, amount, location, and each person's individual characteristics.
Advantages that patients often value include a plan that can be individualized, no surgery required, and some HA products can be considered for dissolving with the enzyme hyaluronidase when the doctor deems it necessary. However, dissolving is not a guarantee of a full return to the original state, and it carries its own risks and limitations. Overfilling can make the face look swollen, heavy, or unnatural, so the goal should not be to fill as much as possible.
Filler does not bring back lost fat or bone, and it does not lift sagging skin in every case. The doctor may therefore suggest another option, or advise against treatment, if the expected benefit does not match the cause or the patient's needs.
How Many Ways Can Hollow Cheeks Be Treated
There is no single number of methods that applies to everyone, but the main options a doctor may consider include:
- HA filler: suitable for some cases that need localized volume added, with product choice matched to the area and approved use
- Autologous fat transfer or surgical facial augmentation: a surgical procedure with its own considerations regarding recovery, results, and risks that differ from filler — requires consultation with an appropriately qualified surgeon
- Skin-tightening devices or skin care: may help with some degree of laxity or thin skin, but does not directly replace lost volume
- Addressing the underlying cause and monitoring: if weight has changed rapidly or there is a related condition/medicine, consult a doctor for assessment before any procedure
Some people may not need treatment at all, or may get a better result from a combination of approaches. The doctor should explain the reasoning, expected benefit, risks, and alternatives before any decision.
What Is a Nasolabial Fold, and How Many Types Are There
ลักษณะร่องแก้มสามกลุ่มที่ใช้อธิบายกับแพทย์
A nasolabial fold is the crease running from the side of the nose down toward the corner of the mouth. How visible it is can change with smiling, age, bone structure, fat distribution, and skin elasticity. To help communicate with the doctor, it can broadly be described in 3 ways:
- Folds clearly visible while smiling or talking: related to natural facial movement
- Folds visible even at rest: may relate to skin and tissue structure, volume loss, or laxity
- Deep folds associated with changes in the mid-cheek area: a flattened cheek or shifted tissue position may make the junction between the cheek and the fold more noticeable
This classification is a way of describing the symptom, not a diagnostic system that replaces an actual examination, and the causes can overlap.
Why You Shouldn't Always Rush to Fill the Fold Directly
The treatment approach depends on the cause and degree of laxity. The doctor may consider HA filler directly in the fold for some patients, or plan treatment of the cheek area first to help balance the overall picture. Filling directly into the fold is not suitable for everyone, and too much volume can make the area look heavy or swollen.
Questions worth asking the doctor include: "What is the main cause of this fold?", "Does it need to be injected directly?", "If I don't want filler, what are the alternatives?", and "What risks or abnormal signs should I contact the clinic about right away?"
How Cheek Filler and Nasolabial Fold Filler Differ
Cheek filler focuses on assessing hollowing or volume in the cheek area, while nasolabial fold filler focuses on assessing the crease running from the side of the nose toward the mouth. Although the two areas are close together, the causes and treatment plans are not always the same. In some people the main problem is in the mid-cheek; in others it is a crease from facial expression; some have both together. You should therefore not use someone else's syringe count or injection plan as your benchmark.
Risks and Safety Care
ความปลอดภัยและสัญญาณที่ต้องรีบพบแพทย์หลังฉีดฟิลเลอร์
Temporary symptoms after injection may include swelling, redness, bruising, pain, or tenderness, and there is a chance of lumps, irregularity, infection, or inflammatory reaction. An uncommon but serious complication is material entering or compressing a blood vessel, reducing blood supply to tissue, which can lead to tissue damage or vision problems. This is why the procedure must be performed by a licensed doctor with anatomical knowledge and a plan for managing complications.
Choose a licensed medical facility, ask for the product name and registration number, verify the product with the Thai FDA, and fully disclose any underlying conditions, medications, allergies, and previous procedures. Do not buy material to inject yourself or use an injection service from someone who is not a doctor.
If after injection you have severe or worsening pain, unusual pale or dark discoloration, mottled skin, blistering, blurred vision, double vision, or loss of vision, contact a doctor and go to the emergency room immediately — do not wait to see if it passes on its own.
Frequently Asked Questions About Cheek and Nasolabial Fold Filler
How many cc of filler are needed for hollow cheeks, and how much does it cost?
There is no fixed amount — it depends on the cause, facial proportions, product, and the goal agreed with the doctor. Prices vary by product, amount, doctor, and facility; ask for the exact product name, total amount, cost, and follow-up plan before deciding.
How long do results last?
Duration depends on the product type, location, amount, and each person's response, so no single duration should be guaranteed for everyone. Follow the product information and your doctor's advice.
Will injection make my face look puffy or fat?
Temporary swelling can occur after treatment, and if too much is added or the location is not suitable, the face can look heavy or unbalanced. A conservative plan and assessment after the swelling subsides helps with better decision-making.
Can hollow-cheek filler be dissolved?
Some HA fillers may be considered for dissolving with hyaluronidase by a doctor, but this does not mean it can always be dissolved immediately or return fully to the original state. Other filler types may be managed differently.
Does the nasolabial fold always need to be injected directly?
Not always. The doctor needs to assess whether the fold comes from facial expression, changes in the cheek area, or another factor, and then choose the appropriate plan.
Is cheek filler better than thread lifting or skin-tightening devices?
There is no single best method for everyone. Filler adds/supports volume, while threads or devices have different lifting goals. The doctor should choose based on the cause and your expectations.
Who should postpone or avoid injection?
Those who are pregnant or breastfeeding, have an infection in the treatment area, are allergic to the ingredients, or have a health condition/medication that may increase risk should tell the doctor and be assessed for suitability first.
Can weight loss cause hollow cheeks, and can filler help?
It may help add volume in some cases, but it must first be assessed whether this is truly volume loss or skin laxity, and you should tell the doctor about any history of weight change.
Do both cheeks need the same amount, and can cheek and nasolabial fold filler be done together?
Not necessarily the same amount — the two sides of the face may differ in structure and volume, and the doctor will plan for balance rather than using equal amounts as the main rule. Some people may have both areas treated together, but the doctor must assess suitability and sequencing; in some cases a staged approach with follow-up is recommended.
Does filling the cheek also help with dark circles or hollows under the eyes?
The effect is not the same for everyone. The under-eye area is a separate concern that needs its own assessment, and it should not be assumed that cheek filler will fix it.
What should I prepare and ask the clinic before treatment?
Disclose your full health history, medications, supplements, allergies, and any previous injections. Do not stop doctor-prescribed medication on your own, and ask about the product, treatment plan, expected results, risks, aftercare, and emergency contact information.
Summary
Hollow cheeks and nasolabial folds can have many different causes, so there is no single formula or standard syringe count for everyone. HA filler may be one option when it suits the concern and the product, but it has limitations and risks. Consulting a licensed doctor at an authorized medical facility, verifying the product, and discussing your goals openly is a safer starting point for your decision.
If you are considering filler for hollow cheeks or nasolabial folds, you can book a facial assessment with a doctor at Orianna Clinic to plan care that suits your cause and individual goals.
