Nasolabial folds, often called smile lines or laugh lines, are the creases that run from the sides of the nose to the corners of the mouth.

Dermal fillers offer a popular, non-surgical treatment option to smooth these folds and restore a youthful appearance. This comprehensive guide explores everything you need to know about treating nasolabial folds with fillers.

Understanding Nasolabial Folds: Causes and Characteristics

Nasolabial folds develop as a natural part of the aging process but can be influenced by factors like sun exposure, smoking, genetics, and repeated facial expressions. These folds form when the skin loses elasticity and volume beneath the surface decreases, causing the skin to sag.

Understanding the anatomy and causes of nasolabial folds is critical for selecting the right treatment approach, especially when considering fillers.

What Are Dermal Fillers and How Do They Work?

Dermal fillers are injectable gels typically made from hyaluronic acid, a substance naturally found in the skin that attracts moisture and adds volume.

When injected into the fold area, fillers restore lost volume, smooth out creases, and lift sagging skin. The procedure is minimally invasive and provides immediate, visible results without surgery.

Types of Fillers Suitable for Nasolabial Folds

Several types of fillers are effective for treating folds, including hyaluronic acid-based fillers like Juvederm and Restylane, calcium hydroxylapatite fillers like Radiesse, and poly-L-lactic acid fillers like Sculptra. Each filler type varies in texture, longevity, and suitability depending on the patient’s skin condition and desired outcome.

Preparing for Your Nasolabial Fold Filler Treatment

Preparation is key to a successful filler treatment. Patients should avoid blood-thinning medications and supplements (like aspirin, ibuprofen, and fish oil) before the procedure to reduce bruising risk.

Consulting with a qualified injector to discuss expectations, medical history, and allergies ensures a tailored treatment plan.

Consultation and Medical History Review:

Your journey starts with a consultation with a qualified injector or dermatologist. During this visit, you’ll discuss your aesthetic goals, medical history, any allergies, and current medications. It’s important to disclose any previous cosmetic treatments or health conditions to avoid complications.

Avoid Blood-Thinning Medications and Supplements:

At least one to two weeks before the procedure, avoid medications and supplements that increase bleeding risk, such as aspirin, ibuprofen, vitamin E, fish oil, and herbal supplements like ginkgo biloba. These can lead to bruising and swelling post-injection.

Minimize Alcohol and Smoking

Refrain from consuming alcohol for 24 to 48 hours before your appointment, as alcohol can thin your blood and increase bruising risk. Smoking also impairs healing, so cutting back or quitting before treatment will improve recovery.

Skin Care Preparation

Keep your skin clean and well-moisturized leading up to the procedure. Avoid harsh exfoliants, chemical peels, or retinoids at least 48 hours before treatment to reduce skin sensitivity and irritation.

Plan Your Schedule

While filler treatments generally have minimal downtime, it’s wise to schedule your appointment when you can relax for a day or two afterward in case of mild swelling or bruising.

Step-by-Step Nasolabial Fold Filler Procedure

The treatment usually begins with cleansing the area and applying a topical numbing cream or local anesthetic. The injector then uses a fine needle or cannula to administer the filler precisely into the nasolabial folds. The entire procedure typically takes 20 to 30 minutes, and patients can resume normal activities immediately.

What to Expect After Nasolabial Fold Filler Injections

Post-treatment, mild swelling, redness, or bruising around the injection site is common but generally subsides within a few days.

Patients may experience slight tenderness, but serious side effects are rare. Following aftercare instructions, such as avoiding strenuous exercise and excessive sun exposure, helps optimize healing and results.

How Long Do Nasolabial Fold Fillers Last?

The longevity of filler results depends on the filler type, patient metabolism, and lifestyle factors. Hyaluronic acid fillers typically last between 6 to 18 months, while calcium hydroxylapatite and poly-L-lactic acid fillers can last longer. Periodic touch-ups are recommended to maintain the desired smoothness of the folds.

Types of Fillers and Their Duration

Hyaluronic acid (HA) fillers such as Juvederm and Restylane are the most popular options for treating nasolabial folds. These fillers typically last between 6 to 18 months. Variations within this range depend on the specific product’s formulation; for example, some denser or cross-linked HA fillers provide longer-lasting results.

Calcium hydroxylapatite fillers like Radiesse may last around 12 to 18 months, sometimes longer, due to their ability to stimulate natural collagen production. Poly-L-lactic acid fillers (Sculptra) work gradually and promote collagen synthesis over time, with effects lasting up to two years or more, but they are less commonly used solely for nasolabial folds.

Individual Metabolism and Lifestyle

Each person’s body metabolizes fillers at a different rate. Factors such as age, skin type, overall health, and lifestyle choices (like smoking or sun exposure) influence how quickly fillers break down. For example, people with faster metabolisms or those who frequently exercise may see filler results fade sooner.

Area of Injection

The nasolabial folds experience significant facial movement due to talking, smiling, and chewing. This dynamic area can cause fillers to break down faster compared to less mobile parts of the face.

Maintenance and Touch-Ups

To keep the nasolabial folds looking smooth and youthful, regular maintenance treatments are recommended. Many patients schedule touch-ups every 12 months, but some opt for more frequent visits depending on their desired appearance and how quickly the filler wears off.

Risks and Side Effects of Nasolabial Fold Fillers

Though fillers are generally safe, risks include bruising, swelling, lumps, and, rarely, vascular complications. Choosing a highly experienced and licensed professional reduces the chance of adverse effects. Immediate reporting of unusual pain or changes in skin color post-injection is critical for prompt treatment.

Alternatives to Fillers for Nasolabial Fold Treatment

While fillers are popular, other treatments like laser resurfacing, microneedling, chemical peels, and surgical facelifts can improve folds. Each option has different invasiveness levels, recovery times, and cost considerations. Patients should discuss alternatives with their dermatologist or cosmetic surgeon.

Combining Fillers with Other Cosmetic Procedures

For enhanced facial rejuvenation, fillers can be combined with Botox, skin tightening treatments, or fat transfer. Botox can relax muscles around the mouth to prevent deeper lines, while skin tightening therapies stimulate collagen. A customized combination often yields the most natural and balanced results.

Botox (Botulinum Toxin) and Fillers: While fillers restore volume and smooth deep creases, Botox relaxes the muscles that cause dynamic wrinkles, such as those around the mouth and nose. When used together, Botox can prevent new lines from forming and reduce the movement that deepens existing folds, complementing the volumizing effects of fillers.

2. Skin Tightening Treatments: Procedures like radiofrequency, ultrasound (Ultherapy), and laser skin tightening stimulate collagen production in the deeper layers of the skin. These treatments improve skin elasticity and firmness, providing a supportive foundation that helps fillers maintain their effects longer and enhances overall facial contour.
3. Microneedling and PRP (Platelet-Rich Plasma): Microneedling creates controlled micro-injuries that promote natural collagen and elastin production. When combined with PRP, which is rich in growth factors, it accelerates skin healing and rejuvenation. This combination improves skin texture and firmness around folds, enhancing filler outcomes.
4. Chemical Peels and Laser Resurfacing: These treatments improve skin tone and reduce pigmentation, fine lines, and rough texture. By resurfacing the skin, they complement filler treatments by making the overlying skin smoother and healthier, which can make folds less noticeable.
5. Fat Transfer: For those seeking longer-lasting volume restoration, autologous fat transfer uses the patient’s fat harvested from other body areas. It can be combined with fillers to provide a more natural, permanent solution for deeper folds.

Cost of Nasolabial Fold Filler Treatments

Costs vary based on the filler type, amount needed, practitioner expertise, and geographic location. On average, treatments can range from $600 to $1500 per session. Many clinics offer payment plans or package deals for multiple sessions to make treatments more affordable.

Finding a Qualified Injector for Fold Fillers

Choosing a certified and experienced injector is paramount to safety and achieving natural-looking results. Look for board-certified dermatologists, plastic surgeons, or licensed medical professionals with specialized training in facial fillers. Reading patient reviews and viewing before-and-after photos can help in making an informed choice.

How to Maintain Results After Nasolabial Fold Fillers

Maintaining chin filler results involves adopting a good skincare routine, protecting skin from sun damage, staying hydrated, and avoiding smoking. Regular follow-up treatments and lifestyle habits that support skin health contribute to longer-lasting and more effective outcomes.

1. Follow Aftercare Instructions: Immediately after filler injections, it’s important to avoid excessive sun exposure, strenuous exercise, and alcohol consumption for at least 24 to 48 hours. These activities can increase swelling or bruising and may affect filler placement.
2. Protect Your Skin from UV Damage: Chronic sun exposure accelerates collagen breakdown and skin aging, which can cause fillers to degrade faster. Always apply a broad-spectrum sunscreen with SPF 30 or higher daily, wear protective clothing, and seek shade when possible.
3. Maintain a Healthy Skincare Routine: Using gentle cleansers, moisturizers, and products containing hyaluronic acid or peptides can help boost skin hydration and collagen production. Avoid harsh exfoliants or treatments that may irritate the skin around the folds.
4. Stay Hydrated and Eat a Balanced Diet: Adequate water intake keeps the skin plump and supple, while nutrient-rich foods provide antioxidants and vitamins essential for skin repair and elasticity. Incorporate foods high in vitamins C, E, and omega-3 fatty acids.
5. Avoid Smoking and Limit Alcohol: Smoking reduces blood flow to the skin and accelerates collagen loss, while excessive alcohol dehydrates the skin, both leading to premature aging and faster filler breakdown.
6. Schedule Regular Touch-Up Treatments: Depending on the filler type used, results typically last 6 to 18 months. Regular follow-ups with your injector help maintain volume and smoothness by replenishing filler as needed.
