Nasolabial folds, commonly referred to as smile lines or laugh lines, are the deep creases running from the sides of the nose to the corners of the mouth. These folds become more prominent with age due to the natural loss of collagen, fat, and skin elasticity. The appearance of nasolabial folds can make the face look older and tired, which is why many people seek treatment to reduce their appearance. One of the most popular non-surgical solutions for nasolabial folds is dermal fillers. This article will explore the nasolabial fold filler technique in detail, focusing on the injection sites, before and after results, and potential complications.
Nasolabial Fold Filler Injection Site
Choosing the correct injection site is crucial for achieving natural and long-lasting results with nasolabial fold fillers. The injection technique varies slightly depending on the individual’s facial structure, skin quality, and the severity of the folds.
1. Identifying the Nasolabial Folds
Before starting the injection, a detailed examination of the nasolabial folds is necessary. Patients may have shallow or deep folds, depending on various factors such as genetics, lifestyle, and age. A thorough assessment allows the practitioner to decide on the type of filler to use and the specific areas that require treatment.
- Shallow Nasolabial Folds: For those with minimal to moderate folds, a superficial injection is usually sufficient to add volume and smooth the appearance of the folds.
- Deep Nasolabial Folds: In cases where the nasolabial folds are more pronounced, a deeper injection may be required to lift the tissues and restore volume.
2. Common Injection Points
The nasolabial fold area consists of two primary injection sites:
- Lateral Injection: This refers to injecting along the outer side of the nasolabial fold. This area is often treated first to provide support to the cheek area, which tends to sag and cause the folds to deepen over time. Lifting this area can help in softening the overall appearance of the fold.
- Medial Injection: This involves injecting closer to the mouth or directly into the fold. Medial injections focus on filling the deep creases within the fold itself, smoothing it out for a more youthful look.
3. Injection Technique
Injecting nasolabial folds requires skill and precision. There are two main techniques used:
- Linear Threading Technique: In this approach, the filler is injected in a linear fashion along the fold. The needle is inserted parallel to the fold, and the filler is deposited as the needle is slowly withdrawn. This technique ensures even distribution of the filler, reducing the appearance of the crease.
- Serial Puncture Technique: Here, small amounts of filler are injected at multiple points along the nasolabial fold. This technique is particularly useful for patients with deeper creases, as it allows for more precise placement of the filler in areas that need extra volume.
4. Types of Fillers Used
The most common types of dermal fillers used for nasolabial folds include:
- Hyaluronic Acid Fillers: Products such as Juvederm, Restylane, and Belotero are popular choices. Hyaluronic acid fillers are versatile, providing both lift and hydration to the skin.
- Calcium Hydroxylapatite (Radiesse): This type of filler is thicker and more suited for deeper folds. It stimulates collagen production, providing long-lasting results.
- Poly-L-lactic Acid (Sculptra): Sculptra works differently by stimulating the body’s own collagen production over time. It is used for more gradual improvement in the appearance of nasolabial folds.

Nasolabial Fold Filler Before and After
Nasolabial fold filler treatments are well-known for producing immediate and noticeable improvements. However, the full results of the treatment typically become apparent a few days after the procedure, once any swelling has subsided. Here is what patients can generally expect before and after the treatment.
1. Before the Treatment
- Consultation: Before undergoing nasolabial fold filler treatment, patients should have a detailed consultation with their practitioner. This will involve a discussion of their goals, medical history, and any potential contraindications to treatment.
- Skin Preparation: The practitioner may recommend avoiding blood-thinning medications, such as aspirin and ibuprofen, a few days before the treatment to reduce the risk of bruising. Alcohol and smoking should also be avoided, as they can increase the chances of post-treatment swelling.
- Pre-Treatment Photography: Before photos are taken from various angles to document the condition of the nasolabial folds. These images will be used for comparison after the treatment to assess the effectiveness of the filler.
2. After the Treatment
- Immediate Results: Right after the procedure, patients typically notice a visible reduction in the depth of their nasolabial folds. The skin may appear smoother, and the face may look more lifted and youthful. However, there might be some initial swelling or redness, which usually subsides within a day or two.
- Final Results: The final results of nasolabial fold fillers can be seen within 1 to 2 weeks, once the swelling completely disappears. At this point, patients can appreciate the full effects of the treatment, which often include smoother, more contoured facial features.
- Longevity of Results: The longevity of the results depends on the type of filler used. Hyaluronic acid fillers typically last 6 to 18 months, while thicker fillers like Radiesse may last longer. Regular maintenance treatments may be required to maintain the desired results over time.
3. Patient Satisfaction
Most patients report high satisfaction with the outcome of nasolabial fold filler treatments. The non-invasive nature of the procedure, combined with immediate, natural-looking results, makes it a popular choice for those looking to rejuvenate their appearance without surgery.
Nasolabial Fold Filler Gone Wrong
While nasolabial fold fillers are generally considered safe and effective, complications can occur, particularly if the procedure is not performed by an experienced practitioner. Understanding potential risks and knowing how to avoid complications is essential for both patients and professionals.
1. Common Complications
- Bruising and Swelling: Minor bruising and swelling are the most common side effects after nasolabial fold filler injections. These are usually temporary and resolve within a few days. Applying ice packs and following post-treatment care instructions can help minimize these effects.
- Asymmetry: If the filler is not distributed evenly or if the injection technique is improper, asymmetry can occur. This might make one side of the face appear fuller or more lifted than the other. Correction often requires additional filler injections to balance the results.
- Lumps or Nodules: Poor injection technique or the use of excessive filler can result in lumps or nodules forming under the skin. These lumps may be felt or seen as small bumps along the nasolabial folds. In some cases, they may dissolve over time, but in others, they may need to be dissolved with hyaluronidase (for hyaluronic acid fillers).
2. Severe Complications
- Vascular Occlusion: One of the most serious risks of dermal filler injections is vascular occlusion, which occurs when the filler accidentally blocks a blood vessel. This can lead to tissue damage or even necrosis if not treated promptly. Symptoms include immediate pain, blanching (whitening) of the skin, and prolonged redness. Practitioners must be trained to recognize and treat vascular occlusion quickly to prevent permanent damage.
- Infection: While rare, infections can occur if proper hygiene protocols are not followed during the injection process. Signs of infection include redness, warmth, swelling, and pus at the injection site. Antibiotics are usually required to treat an infection.
- Allergic Reactions: Some patients may have an allergic reaction to the filler material, especially with non-hyaluronic acid fillers. Symptoms can include itching, swelling, and difficulty breathing. It’s essential to perform a patch test or thoroughly discuss any allergies with the patient before treatment.
3. Preventing Complications
- Choosing an Experienced Practitioner: The best way to avoid complications is to select a qualified and experienced practitioner who has a thorough understanding of facial anatomy and dermal filler techniques. Experienced injectors are more likely to use proper injection techniques, reducing the risk of uneven results or serious complications.
- Follow Post-Treatment Instructions: Patients should carefully follow the aftercare instructions provided by their practitioner. This often includes avoiding vigorous exercise, excessive sun exposure, and massaging the treated area for a few days after the procedure.
- Monitor for Symptoms: Patients should be aware of any unusual symptoms following their treatment, such as prolonged pain, severe bruising, or signs of infection, and contact their practitioner immediately if they experience any of these symptoms.
Conclusion
Nasolabial fold fillers offer an effective and minimally invasive solution for individuals looking to reduce the appearance of smile lines. When performed by a skilled practitioner, the treatment can provide natural-looking results that enhance facial contours and restore a youthful appearance. However, as with any cosmetic procedure, it’s essential to understand the risks and take measures to avoid complications. By choosing the right filler, injection technique, and practitioner, patients can achieve optimal results with minimal downtime.
