Several factors contribute to the deepening of nasolabial folds as we age. These elements often work in tandem, creating the visible changes we associate with facial aging. Let’s explore the primary causes of more prominent nasolabial folds.
Nasolabial folds – those lines that run from the sides of your nose to the corners of your mouth – also sometimes referred to as laugh lines or smile lines, are a natural part of facial anatomy. While they give character to our smiles, they can also become more pronounced with age, leading many people to seek ways to soften their appearance. At Wave Plastic Surgery, we understand that these facial features can be a cosmetic concern for many of our patients, and we’re here to provide you with comprehensive information about what causes nasolabial folds and the various treatment options available.
What Exactly Are Nasolabial Folds?
Nasolabial folds, often called “smile lines” or “laugh lines,” are the natural creases between the sides of the nose and the corners of the mouth. Everyone has these lines to some degree – they’re a normal part of facial anatomy and become visible when we smile or laugh. However, these lines can become more pronounced as we age, even when our faces are at rest.
These folds play a vital role in our facial expressions and are a sign of a life well-lived, filled with laughter and smiles. But when they become deeper and more prominent, they can contribute to an aged appearance that many people wish to address. Understanding why these folds develop can help you make informed decisions about treatment options.
Why Do Nasolabial Folds Become More Pronounced?

Several factors contribute to the deepening of nasolabial folds as we age. These elements often work in tandem, creating the visible changes we associate with facial aging. Let’s explore the primary causes of more prominent nasolabial folds.
1. Natural Aging Process
As we age, our skin loses elasticity and collagen, essential for maintaining youthful-looking skin. This loss of structural support allows the skin to sag and fold, making nasolabial lines more noticeable. Collagen production naturally decreases by about 1% per year after age 20, which explains why these lines gradually become more visible over time.
2. Loss of Facial Volume
Another significant factor is the loss of facial fat that occurs naturally with age. Fat pads in our cheeks provide fullness and support when we’re younger. As these diminish over time, the skin can droop, deepening the nasolabial folds. This volume loss can make a face appear more hollow and accentuate lines and wrinkles.
3. Sun Damage
Years of sun exposure can accelerate collagen breakdown and skin aging, exacerbating the appearance of nasolabial folds. This is why consistent sun protection is crucial to any anti-aging skincare routine. UV radiation damages the skin’s supportive structures and can lead to premature aging, making prevention a key aspect of managing nasolabial folds.
4. Lifestyle Factors
Certain lifestyle choices, such as smoking, poor nutrition, and inadequate hydration, can also contribute to premature aging and more pronounced nasolabial folds. Smoking, in particular, accelerates collagen breakdown and constricts blood vessels, reducing the flow of oxygen and nutrients to the skin. Making positive lifestyle changes can help slow the progression of these lines.
5. Genetics
Your genetic makeup also significantly affects how your skin ages and how pronounced your nasolabial folds may become. Some people are simply predisposed to developing deeper lines in this area. Family history often provides clues about how your facial aging may progress, though environmental and lifestyle factors can still influence the outcome.
Treatment Options For Nasolabial Folds

If you’re concerned about the appearance of your nasolabial folds, you’ll be pleased to know that there are numerous treatment options available, ranging from non-surgical procedures to more comprehensive surgical approaches. At Wave Plastic Surgery, we offer a variety of solutions tailored to each patient’s unique needs and goals. The right approach depends on several factors, including the severity of your nasolabial folds and aesthetic objectives.
Non-Surgical Treatments for Smile Lines

Non-surgical approaches are increasingly popular for addressing nasolabial folds because they typically involve little to no downtime while providing noticeable improvements. These options are ideal for patients with mild to moderate concerns or those not ready for surgical intervention.
Dermal Fillers
Dermal fillers are among the most popular and effective treatments for nasolabial folds. These injectable treatments restore lost volume to the face, effectively “filling in” the folds from beneath the skin. At Wave Plastic Surgery, we offer premium dermal fillers including Juvéderm, Restylane, and Radiesse, which can provide immediate results with minimal downtime.
The procedure typically takes about 15-30 minutes, and results can last anywhere from 6 months to 2 years, depending on the specific product used. Our expert injectors at Wave carefully place the filler to create natural-looking results that complement your facial features.
Neuromodulators
While Botox and other neuromodulators like Xeomin and Dysport don’t directly fill nasolabial folds, they can help reduce their appearance by relaxing the muscles that contribute to their formation. When strategically placed, these injections can lift the corners of the mouth and soften the appearance of nasolabial lines. These treatments are particularly effective when combined with other approaches for a more comprehensive facial rejuvenation.
Skin Tightening Treatments
Non-surgical skin tightening treatments like Ultherapy and Morpheus8 can stimulate collagen production and improve skin elasticity, addressing one of the root causes of nasolabial fold formation. These treatments work beneath the skin’s surface to create gradual, natural-looking improvements.
Wave Plastic Surgery offers cutting-edge skin tightening technologies that can help improve the appearance of nasolabial folds without surgery. Many patients appreciate that these treatments have minimal downtime while providing long-lasting results. The stimulation of new collagen continues for months after treatment, with optimal results typically visible after 3-6 months.
Thread Lifts
Thread lifts offer a minimally invasive option for lifting sagging skin that contributes to nasolabial folds. This innovative procedure involves placing dissolvable threads beneath the skin to lift and tighten facial tissues instantly. Wave Plastic Surgery specializes in advanced thread lift techniques, including Flash Lift and New Lift, which can effectively reduce the appearance of nasolabial folds with results lasting 1-2 years.
Surgical Options for Treating Smile Lines

Surgical procedures may be the most appropriate option for patients seeking more dramatic and longer-lasting results. While these approaches involve more downtime than non-surgical treatments, they also tend to provide more significant and enduring improvements to nasolabial folds and overall facial appearance.
Mini Facelift
A mini facelift is an excellent option for those with moderate nasolabial folds who aren’t ready for a full facelift. This less invasive procedure focuses on the middle and lower portions of the face, effectively addressing nasolabial folds and early jowl formation. Wave Plastic Surgery’s expert surgeons are renowned for their mini facelift techniques, providing natural rejuvenation with less downtime than traditional facelifts.
The procedure typically targets the areas most affected by nasolabial folds, with smaller incisions and a quicker recovery than a complete facelift. Many patients can return to work and social activities within 7-10 days, making it a popular option for those with busy lifestyles.
Traditional Facelift
A traditional facelift may provide the most comprehensive improvement for more significant facial aging, including prominent nasolabial folds. Wave Plastic Surgery offers several advanced facelift techniques, including the signature Wave Lift™, Cure Lift S™, and SMAS Face & Neck Lift, all of which can dramatically improve the appearance of nasolabial folds while addressing other signs of facial aging.
A traditional facelift repositions deeper facial tissues, removes excess skin, and restores volume to create a more youthful facial contour. The results can last for many years, making it a cost-effective long-term solution for facial rejuvenation.
Fat Transfer
Fat transfer, or fat grafting, is another surgical option that involves taking fat from one area of your body and injecting it into the face to restore volume. Wave Plastic Surgery’s Double Pure Fat Grafting technique is particularly effective for addressing volume loss around the nasolabial folds, providing natural-looking results that can last for years.
This procedure offers the dual benefit of contouring the donor area while enhancing facial fullness. Because the procedure uses your tissue, there’s no risk of allergic reaction, and the results often appear exceptionally natural.
How To Get Rid of and Prevent Smile Lines

While treating existing nasolabial folds is essential, preventing their progression is equally valuable. Taking a proactive approach can help maintain your results and slow the development of deeper folds in the future. Here are some strategies to consider for long-term management of nasolabial folds.
- Sun Protection: Always wear broad-spectrum sunscreen and consider protective clothing and sunglasses. Sun damage is one of the primary accelerators of skin aging so this simple step can have significant long-term benefits.
- Skincare Routine: Use quality skincare products containing ingredients like retinoids, vitamin C, and hyaluronic acid. These active ingredients help stimulate collagen production and maintain skin hydration, which can minimize the appearance of nasolabial folds.
- Healthy Lifestyle: Stay hydrated, eat a nutritious diet, avoid smoking, and limit alcohol consumption. What you put into your body reflects on your skin, and healthy habits support overall skin health and resilience.
- Facial Exercises: Some evidence suggests that specific facial exercises may help maintain muscle tone. While not a replacement for medical treatments, facial exercises can complement other approaches to managing nasolabial folds.
- Regular Maintenance Treatments: Consider periodic non-surgical treatments to maintain results and slow aging. Many patients find that a combination of at-home care and professional treatments provides the best long-term outcomes.
