What are Nasolabial Folds (Laugh Lines)?
Nasolabial folds, also known as laugh lines or smile lines, are the skin creases that run from the sides of the nose down to the corners of the mouth. These lines are a normal anatomical feature and become more noticeable over time due to various factors.
While some individuals may have naturally deeper folds due to facial structure—especially those with high cheekbones or prominent “apple cheeks”—nasolabial folds tend to deepen with age.
Several key factors contribute to the worsening of laugh lines over time:
- Loss of Collagen and Skin Elasticity: As we age, the skin produces less collagen and elastin, leading to reduced firmness and support.
- Descent of Facial Fat Pads: The fat pads in the cheeks gradually shift downwards due to gravity and volume loss, creating a sagging effect that accentuates the folds.
- Changes in Bone Structure: Gradual bone resorption in the midface region reduces the underlying structural support, contributing to deeper folds.
- Environmental and Lifestyle Factors: Chronic sun exposure and smoking accelerate skin ageing, making these folds more prominent.
- Genetics: Inherited traits such as skin thickness and facial shape also influence how early and how deeply nasolabial folds appear.
Understanding what causes laugh lines is the first step in choosing the right treatment approach. In the next section, we’ll explore how dermal fillers can help restore volume and soften these lines for a more youthful appearance.
Benefits of Nasolabial Folds (Laugh Lines) Fillers
Dermal fillers are a popular and effective solution for softening the appearance of deep nasolabial folds. By restoring volume to the crease, fillers help to lift and smooth the skin, reducing the prominence of laugh lines.
Key benefits include:
- Instant Results: Folds appear significantly reduced immediately after the procedure.
- Non-Surgical: Minimally invasive with no need for general anaesthesia or incisions.
- Natural-Looking Enhancement: Skillful placement of filler blends seamlessly with surrounding facial features.
- Customisable Volume: The amount of filler used can be tailored to suit individual anatomy and severity of the folds.
- Minimal Downtime: Most patients can resume normal activities shortly after treatment.
Fillers are particularly effective for patients experiencing volume loss and early to moderate signs of ageing in the midface region. When administered by a trained aesthetic doctor, the results are both safe and natural-looking.

How Much Filler Is Needed to Improve Laugh Lines?
The amount of dermal filler required to correct laugh lines varies depending on the depth of the nasolabial folds and individual facial anatomy.
In most cases, 2 to 3 mL of hyaluronic acid filler is needed for noticeable improvement. This typically involves 1 to 1.5 mL per side. Patients with milder folds may require less, while those with deeper creases or significant volume loss may benefit from a slightly higher volume.
Dr Edwin will assess your skin quality, facial structure, and overall symmetry before recommending the optimal amount of filler. The goal is to restore volume gradually and achieve a natural, well-balanced result without overcorrection.
What Type of Filler Is Used for Laugh Lines?
Different types of dermal fillers can be used to treat nasolabial folds, depending on the depth and length of the laugh lines. Choosing the right filler type is essential for achieving smooth, natural-looking results.
For areas near the nose where the fold is deepest, a firmer hyaluronic acid (HA) filler is typically used to lift and restore volume. This helps to reduce the appearance of deep creases and support the surrounding skin.
For the middle to lower section of the nasolabial fold, where the skin is thinner and more dynamic, a softer HA filler may be selected. This allows for subtle correction that integrates seamlessly with facial movements.
For laugh line correction, Dr Edwin typically uses a high-quality, stabilised hyaluronic acid filler from Sweden that utilises NASHA™ technology. This filler type offers strong lift and volume while being fully reversible, making it a preferred option for treating deep nasolabial folds safely and effectively.
Dr Edwin will customise the treatment using fillers of appropriate consistency based on your facial anatomy and ageing concerns. This tailored approach ensures natural, balanced results while softening laugh lines effectively.
Treatment Experience
During your consultation, Dr Edwin will assess your facial structure, skin quality, and the depth of your nasolabial folds. Based on this assessment, a personalised treatment plan will be created, including the precise injection points and filler type most suited to your concerns.
To target deeper areas near the base of the nose, a fine needle may be used to deliver filler directly into the deeper tissue planes. For the middle and lower sections of the fold, a blunt-tipped cannula technique may be preferred to allow smoother distribution of filler while reducing the risk of bruising.
Before each injection, a cold compress is applied to minimise discomfort and reduce the likelihood of bruising or swelling.
The entire procedure typically takes about 15 to 30 minutes. Results are visible immediately, with further improvement over the following days as the filler integrates with the surrounding tissue.
How Soon Will I See Results After Laugh Line Filler Injections?
Results from laugh line filler treatment are visible immediately after the procedure. You will notice a softening of the nasolabial folds and a smoother transition between the cheeks and the mouth area.
Mild swelling may occur after the injections, which can temporarily affect how the final results appear. As the swelling subsides over the next few days and the filler settles into place, the outcome will become more refined and natural-looking.
Most patients see optimal results within 3 to 5 days, with continued improvement as the filler integrates with the surrounding tissue.
Who Is a Suitable Candidate for Laugh Line Fillers?
Laugh line fillers are suitable for both men and women who are looking to reduce the appearance of deep nasolabial folds without undergoing surgery.
You may be a good candidate if you:
- Notice visible creases running from the sides of your nose to the corners of your mouth
- Have mild to moderate facial volume loss or sagging in the midface
- Want immediate, natural-looking results with minimal downtime
- Are in good general health and not pregnant or breastfeeding
- Have realistic expectations about the results and longevity of fillers
During consultation, Dr Edwin will assess your facial anatomy and skin condition to determine whether laugh line fillers are the most appropriate treatment for your concerns.
Can Laugh Line Fillers Be Combined With Other Treatments?
In many cases, laugh line fillers work best when combined with other treatments that address the root causes of nasolabial folds — such as midface sagging and skin laxity.
Depending on your facial structure and degree of ageing, Dr Edwin may recommend a combination approach to achieve more natural and long-lasting results. Commonly combined treatments include:
- Cheek Fillers: Restore volume to the midface, lifting and reducing the appearance of deep folds from above.
- HIFU (High-Intensity Focused Ultrasound): Stimulates collagen production and tightens skin for a subtle lifting effect.
- Threadlifts: Repositions sagging tissue to enhance facial contours and reduce fold depth.
By treating both the nasolabial fold itself and the underlying contributors, combination therapy delivers a more complete facial rejuvenation — often with better results than filler alone.
Is Laugh Line Filler Treatment Painful?
Laugh line filler injections are generally well tolerated and cause minimal discomfort. Most patients describe the sensation as light pinpricks.
The area near the base of the nose, where the folds are typically deeper, may be slightly more sensitive. To reduce discomfort, Dr Edwin applies a cold compress before each injection and may use a blunt-tipped cannula technique where appropriate.
With these measures, most patients find the procedure comfortable and quick, without the need for numbing cream.
How Long Do Nasolabial Fold (Laugh Line) Fillers Last?
The results of laugh line fillers are long-lasting but not permanent. On average, hyaluronic acid fillers used for nasolabial folds can last between 12 to 16 months.
Longevity depends on several factors, including:
- The type of filler used
- The depth of the nasolabial fold
- Individual metabolic rate and lifestyle factors such as smoking or sun exposure
Repeat treatments may be performed once the filler gradually breaks down. Regular maintenance helps to preserve a youthful appearance and prevent the folds from deepening over time.
Are There Any Side Effects After Laugh Line Filler Injections?
Like all injectable treatments, laugh line fillers may cause temporary side effects at the injection site. The most common include:
- Mild swelling
- Redness
- Bruising
These effects typically subside within 5 to 7 days. Dr Edwin may recommend applying a medical-grade recovery cream to minimise bruising and promote faster healing.
More serious complications, such as vascular occlusion (when filler blocks a blood vessel), are extremely rare. However, this risk can be significantly reduced by choosing an experienced doctor who understands facial anatomy and proper injection techniques.
Safety is always prioritised to ensure a smooth and comfortable treatment experience.
