Introduction to Nasolabial Folds / Smile lines / Laugh lines
​
Nasolabial folds, commonly referred to as laugh lines or smile lines, are skin creases that run from the sides of the nose to the corners of the mouth. These folds become more visible as part of the natural aging process and are often associated with changes in facial volume and skin quality.
​
The development of nasolabial folds is influenced by repetitive facial movements, gradual facial volume loss, and the downward shift of facial fat pads. Over time, collagen and elastin production declines, leading to sagging skin and reduced skin firmness.
Laugh lines often deepen due to volume loss in the cheeks or midface rather than the fold itself. Understanding how nasolabial folds form is essential before choosing an appropriate nasolabial fold filler treatment.
Factors such as facial structure, facial anatomy, and skin type all play a role in determining the most suitable approach to treat nasolabial folds effectively.

Understanding Dermal Fillers

What Are Dermal Fillers?
Dermal fillers are injectable treatments designed to restore lost volume, support facial contours, and soften deep folds. They are widely used in aesthetic medicine to address concerns related to volume loss, dynamic wrinkles, and premature aging.
​
Many dermal fillers are formulated using hyaluronic acid, a naturally occurring substance that helps retain moisture and support skin hydration. Hyaluronic acid fillers are commonly used due to their compatibility with the skin and ability to provide natural looking results.
​
In addition to adding volume, fillers can enhance skin hydration and overall skin quality by attracting and retaining moisture within the skin.
How Dermal Filler Injections Work
​
Dermal filler injections work by replenishing volume beneath the skin, helping to reduce the depth of deep nasolabial folds and deep laugh lines.
​
Modern techniques often focus on restoring support in the cheeks or midface rather than injecting filler directly into the fold alone. This approach addresses underlying facial volume loss and helps preserve natural facial expression.
​
The amount of dermal filler required varies depending on the depth of the nasolabial folds and individual facial anatomy. Most patients typically require 2 to 3 mL for visible improvement.
Benefits of Nasolabial Fold Fillers

​
Restoring Facial Volume and Balance
​
Nasolabial fold fillers help restore facial volume that has diminished due to aging. By addressing volume loss in key support areas, fillers can help reduce smile lines and improve overall facial balance.
​
Restoring support to the midface can also reduce tension on the nasolabial folds, allowing the skin to sit more naturally.
​
Improving Skin Quality
​
In addition to restoring volume, fillers can improve skin hydration and support overall skin quality. Some injectable treatments stimulate collagen production, contributing to gradual improvements in skin texture and resilience.
Minimally Invasive With Minimal Downtime
​
Nasolabial fold filler treatments are considered minimally invasive. Most patients experience minimal downtime and are able to return to normal daily activities immediately after the procedure.
Choosing the Right Filler
Filler Type and Treatment Planning
​
Selecting the appropriate filler type depends on several factors, including skin ageing, fold depth, facial contours, and the desired outcome. A personalised treatment plan ensures that treatment aligns with individual facial features and expectations.
​
A firmer filler is typically used near the nose where the fold is deepest and structural support is required. A softer filler may be selected for the middle to lower portion of the nasolabial fold, where the skin is thinner and more dynamic.
​
This layered approach helps maintain natural facial movement while providing balanced correction.
Collagen Stimulators
In some cases, collagen stimulators or collagen stimulating injectables are used to support long-term tissue health. These treatments work by stimulating the body’s natural collagen response and may provide longer-lasting improvements compared to traditional fillers.
​
​Some collagen-stimulating fillers provide deeper structural support and typically last 12 to 18 months, while others stimulate collagen gradually and may last over two years.
Treatment Experience
What to Expect During the Procedure
​
The filler procedure typically takes 15 to 30 minutes to complete. A fine needle or cannula is used, and numbing cream may be applied beforehand to minimize discomfort.
​
A cold compress is often applied before each injection to reduce discomfort, manage blood flow, and lower the likelihood of bruising.
Delivering Natural Results
Proper injection techniques are essential for delivering natural outcomes. The goal is to soften nasolabial folds without overfilling or affecting natural facial expression.
​
Careful placement ensures the filler integrates smoothly with surrounding tissue while maintaining facial harmony.
Preparation and Aftercare
Before Treatment
​
Preparation is usually straightforward. Patients are advised to avoid alcohol and blood-thinning medications before and after filler treatment, as these may increase the risk of bruising.
After Treatment
​
Mild swelling or bruising may occur after the injections and typically lasts a few days. Patients should not panic, as this is a normal and temporary response.
To support healing and optimal results, patients are advised to:
-
Apply cold compresses to the treated area
-
Avoid strenuous exercise for at least 24 hours
-
Avoid touching or massaging the treated area
-
Stay out of extreme heat and direct sunlight
-
Avoid sleeping on the face
-
Avoid heavy makeup or skincare products immediately after treatment
-
Stay well hydrated during recovery
Proper aftercare ensures the filler settles correctly and minimizes potential side effects.
Results and Longevity
When Results Appear
​
Results from nasolabial fold fillers are usually noticeable almost immediately after the procedure. Optimal results are typically seen within 3 to 5 days as the filler integrates with the surrounding tissue.
How Long Results Last
​
The longevity of nasolabial fold fillers depends on the type of filler used, facial movement, and lifestyle factors. Results commonly last 6 to 16 months, with some fillers showing visible effects for 6 to 12 months.
​
Repeat treatments may be necessary as the filler gradually breaks down over time.
Who Is a Suitable Candidate

Most patients are suitable candidates for smile line fillers or laugh line fillers, including both men and women seeking a non-surgical option to soften deep nasolabial folds.
A consultation is essential to assess:
-
Facial anatomy
-
Skin quality
-
Facial contours
-
Medical history
Having realistic expectations helps ensure a balanced and harmonious outcome.
Combining Treatments
Nasolabial fold fillers are often combined with other injectable treatments to address contributing factors such as midface sagging and skin laxity.
​
By treating supporting areas rather than the fold alone, practitioners can achieve more stable and natural-looking results.
Safety and Potential Side Effects
​
Common Side Effects
Common side effects include:
-
Mild swelling
-
Redness
-
Bruising
These effects are temporary and typically resolve within a few days.
Most patients can return to normal activities immediately after treatment.
​
Rare Complications
​
More serious complications are uncommon when treatments are performed using appropriate techniques and careful planning. Proper aftercare further reduces risk.
Cost Considerations
The total cost of nasolabial fold filler treatment varies based on:
​
-
Type of filler used
-
Amount of filler required
-
Depth of the folds
-
Practitioner expertise
Costs typically range from $500 to $1,000+ per syringe, with total cost depending on individual treatment needs.
Key takeaway
Nasolabial folds are a natural part of facial aging influenced by volume loss, facial movement, and changes in skin structure. Nasolabial fold filler treatment offers a minimally invasive approach to restore volume, soften folds, and support a more youthful appearance when performed with careful planning.
An individualized, anatomy-based treatment plan remains essential for achieving safe, balanced, and long-lasting outcomes.
