Nasolabial fold filler is an injectable treatment intended to soften the depth or shadow of the crease running from the side of the nose down to the corner of the mouth. The doctor may consider injecting directly into the fold, into an adjacent area with volume loss, or a combined approach depending on the cause. Hyaluronic acid (HA) is the filler most commonly used, but product types and approved uses differ, so the label and local registration of the specific product should be checked.
A nasolabial fold is a normal anatomical feature — everyone has a different degree of visibility. Having a fold does not mean the skin is abnormal, and treatment is not necessary unless it bothers you.

How Many Types of Nasolabial Folds Are There
กลไกหลักสี่กลุ่มที่ทำให้เกิดร่องแก้ม
There is no single classification used by every clinic or study, but for educational purposes the main mechanisms can be described in 4 groups:
- Adjacent volume-deficit type: reduced volume near the side of the nose or inner cheek creates a shadow and makes the edge of the fold more visible
- Tissue-descent or contour-step type: tissue above the crease descends or becomes more prominent while adjacent tissue has different support, creating a noticeable fold
- Expression-related type: smiling and the action of the lip-elevator muscles deepen the fold; early on it may be visible mainly when smiling
- Mixed type: more than one factor is present, such as volume loss combined with skin laxity and a crease from repeated movement
Age, genetics, changes in bone and fat beneath the skin, skin quality, and facial expression all contribute to how visible the fold is. No single method of looking at a photograph can fully diagnose the cause for everyone.
How the Treatment Plan Is Assessed
The doctor should ask about previous injections, the product type and timing used, underlying conditions, medications and allergy history, and assess the face both at rest and while smiling, including which areas show shadowing or volume loss. The goal should be balanced improvement, not complete elimination of the fold in every expression.
What Are the Treatment Options for Nasolabial Folds

Options depend on the cause, degree of laxity, personal preference, and health. The doctor may consider one approach or several together:
- Direct HA filler injection into the fold: may help reduce the shadow or depth of a fold suitable for filling, with product and amount chosen based on assessment
- Filling an adjacent area or the midface: considered when a genuine volume deficit is found. Cheek filler does not automatically lift the skin or shallow out the fold — 3D imaging evidence has found that filling the cheek alone does not always draw up the skin between the injection point and the fold
- Skin care and sun protection: supports overall skin health, but creams or tightening devices cannot replace volume restoration or correct substantial laxity
- Energy-based tightening, thread lifting, or surgery: may be considered in some cases with laxity or a lifting goal; each option has different limitations, risks, and recovery requirements and needs medical assessment
No single method is best for everyone, and combining several procedures is not always necessary.
What Are the Benefits and Limitations of Nasolabial Fold Filler
- Can adjust the shadow or depth of a localized area when the cause suits filling
- Visible change is often noticed after treatment, but swelling or bruising may mean the early appearance is not the final result
- Some HA fillers can be reduced or dissolved with hyaluronidase when the doctor finds it indicated — this does not mean every risk is easily reversible or that the outcome is guaranteed
- Treatment can be staged and reassessed to reduce the chance of overfilling
Limitations: filler does not stop aging, does not permanently change facial structure, and does not guarantee that the fold will disappear completely or that the face will be lifted. How long results last varies by product type, area, amount, facial movement, and the individual — follow the product information and your doctor's advice.
General Steps and Aftercare
สัญญาณอันตรายที่ต้องรีบขอความช่วยเหลือหลังฉีดฟิลเลอร์ร่องแก้ม
- Consult a doctor; disclose your health history, medications, allergies, and previous procedures
- The face is assessed at rest and while smiling; goals, options, risks, and cost are explained
- If appropriate, the doctor selects a verifiable product and performs the procedure using proper medical technique
- Attend follow-up as scheduled, and contact the clinic immediately if anything feels abnormal
Follow the treating doctor's instructions, avoid pressing, massaging, or rubbing the treated area yourself unless advised, and contact the clinic if any abnormal or urgent symptoms occur.
Side Effects and Warning Signs
Symptoms such as swelling, bruising, redness, pain, or tenderness can occur and usually gradually improve, but lumps, inflammation, infection, or other complications are also possible. An uncommon but serious complication is filler blocking a blood vessel, which can cause tissue to lose its blood supply, tissue death, blurred or lost vision, or stroke.
Stop and seek emergency medical help immediately if you have:
- Unusual or worsening pain
- White, grey, or mottled/dark skin
- Blurred vision or loss of vision
- Weakness, slurred speech, severe dizziness, or sudden severe headache
Tell the doctor beforehand if you are pregnant or breastfeeding, have an infection or skin inflammation in the treatment area, have a history of severe allergy, a bleeding disorder, take medication that increases bleeding, or have previously had filler/injectable material of an unknown type.
Frequently Asked Questions About Nasolabial Fold Filler
How many cc are needed, and how many months does it last?
There is no standard cc amount for everyone — the doctor should assess the cause, depth, and balance, and determine the amount carefully. As for how long it lasts, there is no single number either, since it depends on the product, amount, injection point, movement, and each person's body; check the product's documentation and follow up with your doctor.
Is it better to inject directly into the fold or to fill the cheeks?
It depends on the cause. If it is a localized fold, direct injection may be considered; if there is adjacent volume loss, that area may be considered instead. Filling the cheeks does not automatically lift the fold and may make the face look fuller.
Is there pain, and is recovery needed?
Sensation and recovery vary by person, product, and technique. There may be temporary bruising or tenderness — ask the doctor about pain management and aftercare for the specific product used.
Can it form a lump or shift position?
Lumps, inflammation, and migration of the product are recognized risks, though they do not happen to everyone. Go back to the doctor for assessment — do not massage or press it yourself unless advised.
If I don't like the result, can it be dissolved?
Some HA fillers may be reduced or dissolved with hyaluronidase by a professional who has assessed you, but not every filler material can be dissolved, and additional treatment carries its own risks.
Are threads or tightening devices better than filler?
Each method addresses different factors and has different limitations. Filler adds volume; threads mainly support certain tissues; energy-based devices target some degree of laxity/skin quality. The doctor must assess before choosing.
If my fold is only visible when I smile, can injection make it disappear?
Smiling moves the muscles and skin, so a fold may still be visible with expression. A reasonable goal is a balanced softening — it should not be expected to disappear in every expression.
What age is appropriate for injection?
There is no single age that replaces proper assessment — clinical need, expectations, health, the product, and local regulations must be considered. Minors must be assessed according to strict regulatory and ethical standards.
How should I prepare before treatment?
Fully disclose medications, underlying conditions, allergy history, and any previous filler or procedures. Do not stop prescribed medication or start any new medicine on your own, and follow the clinic's specific instructions.
I've had filler before — can I have more?
You must disclose the product type, location, and timing of the previous injection. If the details are unknown or a lump is found, the doctor may need to assess the area before planning additional filler or correction.
Summary
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 problem 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.
