nasolabial fold: Definition, Uses, and Clinical Overview

Definition (What it is) of nasolabial fold

The nasolabial fold is the natural crease that runs from the side of the nose to the corner of the mouth.
It is an anatomic landmark formed by underlying facial fat pads, muscle movement, and skin attachment points.
In cosmetic medicine, it is commonly discussed as a feature that can become more prominent with aging or volume loss.
In reconstructive surgery, it is used as a reference line and sometimes as a location where scars can be placed to be less noticeable.

Why nasolabial fold used (Purpose / benefits)

In clinical practice, the nasolabial fold is “used” in two main ways: as a landmark for facial analysis and as a treatment target when patients want the fold to look softer or less deep.

From an aesthetic perspective, a prominent nasolabial fold can contribute to a tired, heavy, or aged appearance. This prominence may reflect several factors at once—midface volume changes, skin laxity, descent of cheek tissues, and repeated facial animation. Because it sits centrally on the face, even small changes can affect perceived symmetry and facial balance.

From a reconstructive perspective, the nasolabial fold is important for planning repairs around the nose, cheek, and upper lip. Surgeons may design incisions along natural creases, including the nasolabial fold, to help scars blend with normal shadow lines. The fold region also borders tissue that can sometimes be used in local flap reconstruction (the “nasolabial flap”), depending on the defect and surgeon preference.

Overall, the clinical “benefits” of focusing on the nasolabial fold are improved facial harmony, clearer anatomic planning, and—when appropriate—support for restoration of contour after aging changes or surgery/trauma.

Indications (When clinicians use it)

• Facial assessment and documentation of aging patterns, symmetry, and midface support
• Cosmetic consultation for a patient concerned about deepening creases from the nose to the mouth
• Planning injectable treatment (e.g., dermal filler or biostimulatory products) to soften the fold’s shadowing
• Planning surgical rejuvenation (e.g., facelift or midface lift) when tissue descent contributes to fold prominence
• Planning skin resurfacing in cases where skin texture and fine lines contribute to visible creasing
• Reconstructive planning for defects of the nasal sidewall, upper lip, or cheek where incisions may be hidden in the fold
• Designing/selecting local tissue movement options (e.g., nasolabial flap) in appropriate reconstructive cases

Contraindications / when it’s NOT ideal

Because the nasolabial fold is an anatomic feature—not a single procedure—“contraindications” depend on the specific treatment being considered. Situations where targeting the nasolabial fold may be postponed or approached differently include:

• Active skin infection, inflammation, or open wounds in the treatment area (especially for injectables or resurfacing)
• Uncontrolled medical conditions that increase procedural risk (varies by clinician and case)
• Known allergy or sensitivity to a proposed injectable, anesthetic, or implant material (varies by material and manufacturer)
• Bleeding disorders or use of medications/supplements that raise bruising/bleeding risk (management varies by clinician and case)
• History of problematic scarring or poor wound healing, which may influence incision placement or resurfacing choice
• Unrealistic expectations (e.g., expecting the fold to disappear entirely rather than soften)
• When the primary driver is midface descent or structural deficiency—treating only the fold with filler may be less suitable than restoring cheek support or using a lifting approach (varies by anatomy and clinician assessment)
• When heavy filler placement could create unnatural fullness near the mouth or alter facial expression; another approach may be preferred (varies by clinician and case)

How nasolabial fold works (Technique / mechanism)

The nasolabial fold itself does not “work” like a device or medication; it is a crease created by facial anatomy and movement. Clinicians address it by choosing techniques that reduce the fold’s prominence through one or more mechanisms:

• Restore volume: Adding support in the fold or (often) in the midface/cheek can reduce shadowing. This is commonly done with injectables such as hyaluronic acid fillers, other filler types, or fat transfer (varies by clinician and case).
• Reposition tissues: Surgical rejuvenation can lift and re-drape descended cheek tissues, which may indirectly soften the nasolabial fold. This may involve facelift techniques, midface lifting, and suspension with sutures (technique varies by surgeon).
• Tighten and improve skin quality: Energy-based treatments and resurfacing (e.g., laser, radiofrequency, microneedling devices) can improve texture and mild laxity, which may reduce how sharply the fold is seen. These typically do not replace lost volume to the same degree as fillers or surgery.
• Camouflage rather than erase: Many approaches reduce the depth/contrast of the fold rather than eliminating the crease, because the fold is partly a normal facial contour and an expression-related line.

Typical tools/modalities depend on the approach:

• Minimally invasive: needles or cannulas for injectables; small entry points; topical anesthetic or local anesthesia
• Surgical: incisions, sutures, tissue repositioning, and dressings; sedation or general anesthesia may be used depending on extent
• Non-surgical devices: topical anesthetic, protective eyewear, and device handpieces delivering controlled energy to the skin

nasolabial fold Procedure overview (How it’s performed)

Since there is no single “nasolabial fold procedure,” the workflow below describes how clinicians commonly approach treatments targeting the nasolabial fold. Exact steps vary by clinician and case.

1. Consultation
   Discussion of goals (softening vs lifting vs skin quality), medical history, prior procedures, and preferences.

2. Assessment / planning
   Facial analysis at rest and during expression; evaluation of cheek support, skin thickness, and symmetry. Photos may be taken for documentation. A plan may include treating adjacent areas (often the midface) rather than focusing only on the crease.

3. Prep / anesthesia
   Skin cleansing and marking. Options may include topical numbing cream, local anesthetic, or (for surgery) sedation/general anesthesia.

4. Procedure
   – Injectables: product placement with needle or cannula in targeted planes to restore support and smooth transitions.
   – Surgery: lifting/repositioning of tissues and/or volume restoration; incisions are placed based on the selected technique.
   – Devices/resurfacing: controlled energy delivery to improve texture and laxity, sometimes in a series.

5. Closure / dressing
   Injectables typically require minimal dressing. Surgical approaches may involve sutures, dressings, and specific wound care instructions. Device treatments may include soothing topical products.

6. Recovery / follow-up
   Short-term swelling or bruising can occur with injectables; longer recovery is typical after surgery. Follow-up visits may be used to assess healing, symmetry, and whether additional treatment is appropriate.

Types / variations

Treatments related to the nasolabial fold are often grouped into non-surgical, minimally invasive, and surgical categories. Selection depends on anatomy, goals, and clinician assessment.

• Non-surgical skin-focused options (no added volume)
• Resurfacing (laser or light-based treatments) to improve texture and fine lines
• Radiofrequency or ultrasound-based tightening to address mild laxity (results vary by device and case)

• Microneedling (with or without radiofrequency) for skin quality

• Minimally invasive volume/support options

• Dermal fillers: commonly hyaluronic acid; other categories exist (varies by material and manufacturer)
• Biostimulatory injectables: intended to stimulate collagen over time (mechanism and suitability vary)

• Fat transfer (fat grafting): using a patient’s own fat to restore volume; survival of grafted fat varies

• Technique variations within injectables

• Needle vs cannula placement
• Treating the fold directly vs treating the cheek/midface to support the fold indirectly

• Layer/plane of placement (more superficial vs deeper), chosen to match anatomy and reduce irregularities

• Surgical options (tissue repositioning)

• Facelift techniques that reposition descended tissues (approach varies by surgeon)
• Midface lift/cheek lift approaches focused on the central face

• Structural procedures in selected cases (e.g., implants) when skeletal support is a key factor (varies by clinician and case)

• Reconstructive variation

• Nasolabial flap: a local flap that borrows tissue near the nasolabial fold to reconstruct nearby defects; it is planned to respect facial subunits and natural creases (case-dependent).

• Anesthesia choices

• Office-based: topical anesthetic and/or local anesthesia are common for injectables and many device treatments
• Procedure suite/OR: sedation or general anesthesia may be used for surgical approaches, depending on extent and patient factors

Pros and cons of nasolabial fold

Pros:

• Central facial landmark that helps clinicians assess proportion, symmetry, and aging patterns
• Multiple treatment pathways exist (skin-focused, volume-focused, lifting-focused), allowing individualized planning
• Many options are incremental, meaning changes can often be made gradually over time (varies by approach)
• The fold can help conceal certain reconstructive incisions because it is a natural crease
• Non-surgical and minimally invasive treatments are commonly performed in outpatient settings (case-dependent)

Cons:

• The nasolabial fold is partly a normal anatomic contour; complete elimination is not a typical or realistic goal
• Treating only the crease may not address underlying causes such as cheek descent or volume loss elsewhere
• Injectables can cause bruising, swelling, asymmetry, or contour irregularities; risks vary by product and technique
• Overcorrection may look unnatural, especially near the mouth where expression dynamics are complex
• Surgical approaches involve more downtime and carry broader procedural risks than non-surgical options (varies by clinician and case)
• Longevity varies widely by anatomy, technique, and material; maintenance may be needed

Aftercare & longevity

Aftercare and longevity depend on the chosen treatment category and the patient’s baseline anatomy. In general, clinicians consider:

• Technique and placement: Depth, location, and amount of product (for injectables) or the vector/extent of lift (for surgery) can influence how long results appear to last.
• Material characteristics: Different fillers and biostimulatory products behave differently over time (varies by material and manufacturer). Fat graft survival varies by technique and individual biology.
• Skin quality and thickness: Thinner skin may show contour changes more easily, while thicker skin may require different strategies to create a smooth transition.
• Facial movement: Smiling, chewing, and habitual expressions continually fold the area, which can influence how creasing returns.
• Lifestyle and exposures: Sun exposure, smoking, and overall skin care can affect collagen quality and skin elasticity over time.
• Weight changes and aging: Ongoing aging and significant weight change can alter midface volume and the fold’s appearance.
• Follow-up and maintenance: Some approaches are designed for periodic maintenance, while surgical repositioning may be longer lasting but still changes as aging continues.

Recovery experiences also vary. Bruising and swelling are common short-term issues after injectables, while device treatments can involve redness or sensitivity. Surgical recovery depends on the extent of lifting and incision placement.

Alternatives / comparisons

Because the nasolabial fold can be influenced by volume, laxity, and skin texture, alternatives are best compared by what they primarily change:

• Injectables (volume/support) vs energy-based treatments (skin quality)
• Injectables primarily reduce the fold’s shadow by restoring support or smoothing transitions.

• Energy-based treatments primarily target texture and mild laxity; they may not replace lost volume to the same degree.

• Treating the fold directly vs treating the midface

• Direct fold treatment may soften a localized crease.

• Midface/cheek support can indirectly reduce the fold by improving the overall contour transition (common in planning, varies by clinician and case).

• Temporary vs longer-duration strategies

• Many injectables are temporary and may require maintenance.

• Surgical repositioning can be longer lasting, but it involves more downtime and procedural risk, and aging continues.

• Camouflage options

• Makeup and lighting techniques can reduce the appearance of shadowing in photos or daily wear, but they do not change underlying anatomy.

• Orthodontic/orthognathic or dental considerations (selected cases)

• In some people, dental occlusion, lip support, or skeletal structure contributes to midface and perioral contour. Addressing these factors is a different pathway than cosmetic soft-tissue treatment and is evaluated case-by-case.

No single alternative is universally “better.” Clinicians typically match the approach to the dominant cause of fold prominence and the patient’s goals.

Common questions (FAQ) of nasolabial fold

Q: Is the nasolabial fold normal?
Yes. The nasolabial fold is a common facial crease and is part of normal anatomy and expression. It often becomes more noticeable over time due to changes in volume, skin elasticity, and tissue position.

Q: Why does the nasolabial fold get deeper with age?
Multiple factors can contribute, including midface volume changes, descent of cheek tissues, and reduced skin elasticity. Repeated facial movement can also accentuate creasing. The relative contribution of each factor varies by individual anatomy.

Q: Are treatments aimed at the nasolabial fold painful?
Discomfort varies by procedure and person. Injectables often use topical numbing or local anesthesia, and device treatments may include numbing measures. Surgical approaches use anesthesia appropriate to the extent of surgery.

Q: What is the downtime after nasolabial fold filler or other non-surgical treatments?
Downtime varies. Many people experience temporary swelling, redness, or bruising after injectables, while resurfacing or energy-based treatments can cause redness and sensitivity for a period of time. The exact recovery window depends on technique, skin sensitivity, and the modality used.

Q: Do nasolabial fold treatments leave scars?
Injectables and most device treatments typically do not create noticeable scars because they use small entry points or no incisions. Surgical procedures can leave scars, but incisions are often placed in locations chosen to be less conspicuous; how scars heal varies by individual.

Q: How long do results last?
Longevity depends on the approach. Some fillers are designed to be temporary, biostimulatory products may evolve gradually, and fat transfer can have variable persistence. Surgical repositioning can be longer lasting, but results still change with time and ongoing aging.

Q: Are nasolabial fold treatments safe?
All procedures carry risk. Injectables can include bruising, swelling, asymmetry, and other complications; device treatments have their own risks such as irritation or pigment changes; surgery has broader operative risks. Safety depends on patient factors, clinician training, technique, and appropriate product selection.

Q: Why might a clinician treat the cheeks instead of injecting the nasolabial fold directly?
In some faces, the fold appears deeper because the cheek has lost support or descended, creating a sharper transition. Restoring midface support can soften the fold indirectly and may look more balanced in certain patients. The best plan varies by anatomy and clinician assessment.

Q: How much does nasolabial fold treatment cost?
Costs vary widely by region, clinician experience, facility setting, and the type/amount of product or extent of surgery. Injectables are often priced by syringe or session, while surgical options include anesthesia and facility costs. A personalized estimate typically requires an in-person assessment.

Q: Can the nasolabial fold be completely removed?
Complete removal is usually not the goal because the nasolabial fold is a natural contour and functional crease that appears with expression. Many treatments aim to soften the fold and improve the transition between the cheek and upper lip. The achievable change varies by anatomy, skin quality, and technique.
