Dermal Fillers for Nasolabial Folds: Understanding Treatment Options

Dermal fillers for nasolabial folds are injectable treatments — most commonly using hyaluronic acid — designed to add volume and structure to the lines that run from the nose to the corners of the mouth. They may help soften the appearance of these creases, though results vary between individuals and a professional consultation is essential to assess suitability.

Nasolabial folds, sometimes informally referred to as "smile lines" or "laugh lines," are natural anatomical features present on most faces. They become more noticeable over time as a result of several age-related changes, including loss of facial volume, changes in skin elasticity, and the cumulative effects of facial movement and expression.

These folds are a normal part of facial anatomy and are present to some degree in younger faces too — particularly when smiling. However, as the ageing process progresses, these lines may deepen and become more prominent even at rest, which is when many patients begin to seek information about treatment options.

It is important to approach the subject with balanced expectations. Not every nasolabial fold requires or would benefit from treatment, and the decision to pursue any aesthetic procedure should always be based on an individual's own goals and a thorough assessment by a qualified practitioner.

Dermal fillers used to address nasolabial folds are most commonly formulated with hyaluronic acid (HA) — a substance naturally found in the skin that plays a key role in maintaining hydration and volume. When injected into or adjacent to the nasolabial fold area, HA fillers add volume beneath the skin's surface, which can help soften the appearance of the crease.

The injection technique used will vary depending on the individual's anatomy, the depth of the fold, the degree of volume loss, and the practitioner's clinical assessment. Some practitioners may also address surrounding areas — such as the cheeks — to achieve a more natural-looking result, as volume loss in the mid-face can contribute significantly to the appearance of nasolabial folds.

The procedure is typically performed using a fine needle or cannula, and a topical anaesthetic is often applied beforehand to help manage any discomfort. Most treatment appointments take between 30 and 60 minutes in total, including consultation, preparation, and the injection process itself.

To understand why nasolabial folds develop and deepen with age, it helps to have a basic understanding of how the skin and underlying facial structures change over time.

From our mid-twenties onwards, the skin's production of collagen — the structural protein responsible for firmness — gradually begins to decline. Elastin, another key protein that allows skin to "spring back" after movement, also degrades with age. As a result, the skin becomes progressively thinner, less firm, and less resilient.

Beneath the skin's surface, the face is supported by compartments of fat that provide structure and volume. With age, these fat pads can diminish, shift downwards, or redistribute — contributing to hollowing in some areas and the appearance of folds or drooping in others. The cheek fat pads, for example, play a significant role in supporting the mid-face; as they reduce, the tissue around the nasolabial area can appear heavier and more pronounced.

Bone resorption — the gradual reduction in the facial skeleton over time — also contributes to changes in facial structure, as the underlying support for overlying soft tissues alters.

Understanding these multiple contributing factors explains why skilled practitioners often take a holistic approach to facial assessment rather than simply treating a fold in isolation.

Hyaluronic acid is the active ingredient in the majority of dermal fillers used for nasolabial folds in clinical practice. Its prevalence in aesthetic medicine is due to several properties that make it well-suited to this application.

HA is a naturally occurring molecule found throughout the body — including in the skin, joints, and connective tissues — where it binds to water and contributes to hydration and volume. In filler formulations, cross-linked hyaluronic acid is used, which means the molecules have been chemically modified to create a more stable gel that resists rapid breakdown.

One notable characteristic of HA fillers is that they are reversible. In the event of an adverse reaction or an outcome the patient is not satisfied with, an enzyme called hyaluronidase can be used to dissolve the filler. This reversibility is one reason why hyaluronic acid fillers are often considered a more manageable option compared to some other injectable materials.

Different HA filler products are formulated with varying levels of thickness (viscosity) and elasticity, allowing practitioners to select a product appropriate to the treatment area and the individual's anatomical needs.

Patients who may find it helpful to seek a professional consultation about nasolabial folds often include those who:

• Notice deeper or more prominent lines developing around the nose and mouth area that are visible at rest
• Are experiencing broader changes in facial volume or contour associated with the natural ageing process
• Have researched non-surgical options and wish to explore whether aesthetic treatments may be appropriate for their individual situation
• Have realistic expectations and a genuine interest in understanding what treatment may and may not achieve
• Are in generally good health and do not have contraindications to injectable treatments

It is equally important to recognise that not everyone who notices nasolabial folds will wish to pursue treatment — and this is entirely valid. Many people choose to embrace natural facial changes and find that the lines do not significantly affect their confidence or wellbeing.

A professional consultation is not a commitment to treatment; it is simply an opportunity to receive personalised, expert information to help you make an informed decision. A qualified practitioner will take a detailed medical history, assess your facial anatomy, discuss your goals, and advise on whether treatment is appropriate for you.

Managing expectations is a central part of responsible aesthetic practice. Dermal fillers for nasolabial folds can — in appropriate candidates — help soften the appearance of these lines and restore some degree of volume to the surrounding area. However, there are important considerations to keep in mind.

Results are not permanent. Hyaluronic acid fillers are gradually broken down by the body over time. Most patients find that results in the nasolabial area last between 9 and 18 months, though this varies considerably based on the product used, the volume injected, individual metabolism, and lifestyle factors.

Results are not guaranteed. The degree of improvement achievable depends on factors including the depth of the fold, the individual's skin quality, the volume of tissue loss present, and the underlying anatomical causes of the fold. In some cases, addressing the cheeks or other adjacent areas may produce a more balanced outcome than treating the nasolabial fold alone.

Treatment does not stop the ageing process. Dermal fillers address the current appearance of a fold but do not prevent future changes associated with ageing. Many patients choose to maintain results with periodic follow-up treatments over time.

Individual variation is significant. No two patients will have identical experiences or outcomes, even with the same product and technique.

Potential Benefits

• May help soften the visible depth of nasolabial folds in appropriate candidates
• Results are typically visible relatively soon after treatment
• The procedure is minimally invasive and does not require general anaesthesia
• HA fillers are reversible, which offers a degree of reassurance
• Treatment can often be performed alongside assessment of broader facial concerns

Limitations and Considerations

• Results are temporary and require maintenance treatments to sustain
• The procedure is not suitable for everyone — pre-existing medical conditions, certain medications, pregnancy, and breastfeeding are among the contraindications
• Deeper or more complex folds may not respond as well to filler treatment alone
• Overfilling of the nasolabial area can result in an unnatural appearance — skilled assessment and conservative technique are important
• As with any injectable treatment, there are risks associated with the procedure (see below)

As with all aesthetic injectable treatments, dermal fillers carry a range of potential risks and side effects. Being well-informed about these is an essential part of the decision-making process.

Common and generally temporary side effects may include:

• Swelling, bruising, and redness at the injection site
• Tenderness or mild discomfort in the treated area
• Temporary asymmetry as swelling resolves

Less common but clinically significant risks include:

• Nodule formation or irregular texture beneath the skin
• Infection at the injection site
• Delayed inflammatory reactions
• Filler migration

Rare but serious complications can include vascular occlusion — where filler inadvertently enters or compresses a blood vessel, potentially compromising blood supply to surrounding tissue. This is a rare but potentially serious complication that underscores the importance of having any injectable aesthetic treatment performed only by a qualified and experienced practitioner working in an appropriate clinical environment.

Patients should always ensure their practitioner holds appropriate qualifications, is registered with a relevant professional regulatory body, and is working in accordance with current UK guidelines.

For those interested in understanding the broader landscape of skin rejuvenation and facial treatment options available at Pantaleo Clinic, a range of educational resources are available.

Following dermal filler treatment to the nasolabial area, practitioners will typically provide personalised aftercare guidance. General educational considerations often include:

In the first 24–48 hours:

• Avoiding strenuous exercise, excessive heat (saunas, steam rooms), and alcohol, which may exacerbate swelling or bruising
• Avoiding touching or massaging the treated area unless specifically advised to do so by your practitioner
• Sleeping with the head slightly elevated can help minimise swelling for some patients

Ongoing skincare considerations:

• Sun protection is important for maintaining skin health and protecting the treatment area — a broad-spectrum SPF of at least 30 should be used daily
• Keeping the skin well-hydrated supports overall skin quality
• Avoiding smoking, which is known to accelerate collagen degradation and negatively affect skin health
• Attending any follow-up appointments your practitioner recommends

Long-term skin health: Maintaining a good baseline skincare routine — including cleansing, moisturising, and consistent sun protection — can support the overall appearance of the skin in the nasolabial area and beyond. Some patients also explore complementary treatments such as polynucleotide skin rejuvenation to support skin quality alongside volume-based treatments.

• Nasolabial folds are a natural feature of facial anatomy that may deepen with age due to collagen loss, fat redistribution, and changes in facial structure.
• Dermal fillers — most commonly hyaluronic acid-based — are one option that may help soften the appearance of nasolabial folds in appropriate candidates.
• Results from dermal filler treatment are temporary, typically lasting between 9 and 18 months, and are not guaranteed.
• Treatment is not suitable for everyone; individual suitability must be assessed by a qualified practitioner during a thorough consultation.
• There are potential risks and side effects associated with injectable treatments that should be understood before proceeding.
• Maintaining realistic expectations and prioritising long-term skin health are important aspects of any aesthetic treatment journey.

How long do dermal fillers for nasolabial folds typically last?

The longevity of dermal filler results in the nasolabial area varies between individuals, but many patients find that results last approximately 9 to 18 months. Factors influencing how long results last include the specific product used, the volume injected, the individual's metabolism, lifestyle habits such as smoking, and the extent of physical activity. Some patients metabolise filler more quickly than others. Practitioners will typically recommend a follow-up review to assess results and discuss whether a maintenance treatment may be appropriate. No filler treatment is permanent, and ongoing treatments are required to sustain results over time.

Are dermal fillers for nasolabial folds painful?

Most patients describe the procedure as mildly uncomfortable rather than significantly painful. A topical anaesthetic cream is commonly applied to the treatment area before the procedure begins, which helps to reduce discomfort during the injection process. Many HA filler products also contain a small amount of lidocaine (a local anaesthetic) within the formulation itself, which can further minimise discomfort during treatment. Individual pain tolerance varies, and patients are encouraged to discuss any concerns about comfort with their practitioner during the consultation, so that appropriate steps can be taken to make the procedure as comfortable as possible.

Is there any downtime associated with dermal filler treatment?

Dermal filler treatment for nasolabial folds is generally considered a low-downtime procedure, though this does not mean there are no temporary side effects. Most patients experience some degree of swelling, redness, and possibly bruising in the treated area in the days following treatment. These effects are usually mild and resolve within a few days to a week, though this varies between individuals. Most people are able to return to daily activities relatively soon after treatment, though practitioners may advise avoiding certain activities — such as strenuous exercise or excessive heat — for the first 24 to 48 hours.

Can anyone have dermal fillers for nasolabial folds?

No — dermal filler treatment is not appropriate for everyone. There are several contraindications that may make treatment unsuitable for certain individuals, including pregnancy, breastfeeding, active skin infections in or near the treatment area, certain autoimmune conditions, and the use of particular medications such as blood-thinning drugs. Age is also a consideration — in the UK, aesthetic injectable treatments should only be performed on adults aged 18 or over, and practitioners are required to undertake appropriate consultations to assess suitability. Individual anatomy, skin condition, and treatment goals all factor into whether filler treatment is the most appropriate option for a given patient.

What are the risks of dermal fillers for nasolabial folds?

As with all injectable aesthetic treatments, dermal fillers carry a range of potential risks. Common side effects include temporary swelling, bruising, redness, and tenderness at injection sites. Less commonly, patients may experience nodule formation, infection, or delayed inflammatory reactions. A rare but serious risk is vascular occlusion, where filler affects blood vessel function — this can have significant consequences if not identified and managed promptly. Choosing a qualified, experienced practitioner who works in an appropriate clinical setting significantly reduces — though does not eliminate — the risk of complications. Patients should always ensure their practitioner has the skills and equipment to recognise and manage potential adverse events; many patients also find it helpful to understand how clinics work to avoid vascular occlusion.

How do I know whether dermal fillers or another treatment might be more suitable for me?

Determining the most appropriate treatment approach for nasolabial folds — or any facial ageing concern — requires a thorough individual assessment by a qualified practitioner. There is no single treatment that is appropriate for everyone; what may be suitable depends on your anatomy, the underlying causes of the fold, your skin quality, your health history, and your aesthetic goals. Some individuals may benefit from addressing mid-face volume loss with cheek fillers rather than — or in addition to — directly treating the nasolabial area. Others may be better suited to alternative approaches. A detailed consultation is the only way to receive personalised guidance.

Nasolabial folds are a natural part of facial ageing, and for those who find they become a source of concern, it is entirely reasonable to explore what treatment options may be available. Dermal fillers — particularly those based on hyaluronic acid — represent one of the most established non-surgical approaches to addressing these lines, and when performed by a qualified and experienced practitioner, they can form part of a well-considered facial rejuvenation approach.

However, it is equally important to approach this topic with realistic expectations, a thorough understanding of the potential risks and limitations, and a clear sense of your own goals. Not everyone will be suited to treatment, and not every nasolabial fold will respond in the same way. The ageing process is complex, and an individualised assessment is always the starting point for responsible aesthetic care.

If you are considering treatment for nasolabial folds, seeking a consultation with a qualified aesthetic practitioner is the most important first step. A professional assessment will allow you to receive personalised information tailored to your specific anatomy, health, and expectations.

Treatment suitability, risks, and expected outcomes should always be assessed individually during a professional consultation.
