Nasolabial folds are one of the facial areas that can show signs of ageing most clearly. Many people start noticing smile lines from around the age of 25, and these lines may gradually deepen over time, making the face look tired or older than it actually is. Even makeup may not fully cover them.
Dermal filler for nasolabial folds is one of the most popular treatment options for this concern because results can be seen immediately without surgery or downtime. However, to achieve a natural-looking result without swelling or lumpiness, it is important to understand both the cause of the problem and the properties of each filler brand before making a decision.
Before choosing a treatment, it is important to understand what is causing your nasolabial folds, as each cause requires a different approach. Treating the wrong area may make the folds appear deeper than before.
A correct assessment by an experienced doctor is the most important step before filler treatment. Injecting filler directly into the nasolabial fold alone, especially when the real cause comes from the under-eye area, may make the face look unnaturally puffy.
It is also important to remember that nasolabial folds are rarely an isolated concern. In many cases, deep folds are connected to nearby facial areas, such as under-eye hollows that make the cheeks look lower, lips that become thinner with age and make the lines around the mouth more noticeable, or sunken temples that affect the balance between the upper and lower face. Treating only the nasolabial folds without looking at the face as a whole may lead to less natural-looking results.
If you also have under-eye concerns, such as dark circles or hollowness, under-eye filler may help the face look fresher and younger than treating the nasolabial folds alone. Similarly, people with thin or poorly defined lips may consider lip filler as part of the treatment plan, as better proportion in the lower face can make the nasolabial folds appear softer without using too much filler in that area. For those with sunken temples along with deep nasolabial folds, temple filler can help restore the upper facial structure, improving overall facial balance and creating a naturally more youthful appearance.
Nasolabial fold filler may be suitable if you:
If your nasolabial folds are still mild, or if you are hesitant about having filler, your doctor may recommend other treatment options that are better suited to your concerns, as discussed in the next section.
Nasolabial fold filler offers the most precise and targeted correction for deep smile lines, allowing the doctor to restore lost volume and achieve natural-looking contouring. HIFU, on the other hand, is better suited for people who want preventative treatment or are not yet ready for injectable procedures. In many cases, doctors may recommend combining filler with HIFU or other lifting treatments to achieve longer-lasting and more balanced results than using either treatment alone.
The nasolabial fold area is constantly moving with facial expressions, so the ideal filler should be flexible, integrate smoothly into the tissue, and resist lumping. The best choice depends on the depth of the folds, the underlying cause, and your individual skin characteristics.
These cases are best treated with firmer fillers that provide strong structural support and maintain their shape over time. Examples include:
Fillers in this category typically last 12–24 months and are suitable for patients with more advanced volume loss who want longer-lasting results.
Medium-density fillers provide a balance between effective volume restoration and natural facial movement. Popular options include:
These fillers generally last 12–15 months and are among the most popular choices for people in their 30s and 40s.
Patients with shallow lines or thinner skin usually benefit from softer fillers with smaller molecules that spread evenly through the tissue without creating visible lumps. These fillers also improve skin hydration while softening fine lines.
In addition to traditional hyaluronic acid fillers, collagen biostimulators are becoming increasingly popular. Rather than providing immediate volume alone, these injectable treatments gradually stimulate the body’s natural collagen production. They are ideal for patients who prefer subtle, progressive improvements and long-term skin rejuvenation while maintaining a natural appearance.
If you are unsure which filler is most suitable for your nasolabial folds, it is best to consult an experienced doctor for a personalized assessment. Each filler has different properties, including firmness, flexibility, and behavior within the tissue. Choosing the wrong product for the wrong indication may lead to results that are less natural or do not fully address the underlying cause of the problem.
The amount of filler needed depends on the depth of the nasolabial folds and each patient’s treatment goals. In general:
Nasolabial fold filler at The Metro Clinic starts from THB 15,000 per 1 CC, depending on the filler brand and how long the results last. You can view the full price list and current promotions on our treatment pricing page.
Nasolabial fold filler is a targeted and fast-acting option for those concerned about deep smile lines. However, good results do not depend on the filler brand alone. Accurate assessment of the underlying cause and the doctor’s injection technique play a greater role in achieving a natural-looking outcome.
If you are unsure which treatment is most suitable for your nasolabial folds, the medical team at The Metro Clinic is happy to provide a consultation, assess your concerns, and create a treatment plan tailored to your needs.
