Nasolabial Folds

Discover the causes of nasolabial folds and the most effective ways to prevent and treat smile lines for a smoother, naturally youthful appearance.

Nasolabial Folds

Overview

Nasolabial folds, often called smile lines or laugh lines, are among the most common facial concerns related to ageing.

These natural creases run from the outer edges of the nose to the corners of the mouth. In youth, they appear primarily during expression. With time, they become visible even at rest and can cast shadows across the midface, creating a tired or heavy look.

This guide explains why nasolabial folds form, how to slow their progression, and the most effective professional and at-home treatments available today.

What Are Nasolabial Folds?

Nasolabial folds are the natural creases that run from the sides of the nose to the corners of the mouth. They mark the boundary between the cheeks (midface) and the upper lip. These folds are present from early childhood and are shaped by the underlying bone structure, the distribution of facial fat, and the quality of the skin.

In younger faces, nasolabial folds are usually soft, shallow, and mostly visible when smiling or making expressions. This youthful appearance is supported by:

  • Strong collagen and elastin fibres, which give the skin elasticity and resilience
  • Full, well-positioned cheek fat pads, particularly the medial and lateral malar pads, which provide lift
  • Stable midface bone structure, which helps support the overlying soft tissue

As we age, several changes contribute to deeper folds:

  • Thinning skin from reduced collagen and elastin
  • Loss and descent of midface fat, reducing natural cheek support
  • Subtle bone changes, particularly in the upper jaw (maxilla), which decrease forward projection
  • Lower skin hydration and elasticity, often linked to declining hyaluronic acid levels

Together, these factors transform dynamic smile lines into permanent folds that remain visible even when the face is at rest.

What Causes Nasolabial Folds to Deepen

Nasolabial folds deepen through a combination of intrinsic ageing, genetic factors, and environmental influences. Key drivers include:

1. Collagen and Elastin Decline

From around age 25, the skin’s collagen and elastin synthesis progressively reduces. The surrounding dermal matrix becomes thinner and less resilient, allowing the fold to appear more pronounced.

2. Midface Volume Loss

Ageing leads to a reduction and descent of key fat pads such as the medial and lateral malar fat pads, diminishing cheek support. This is one of the primary anatomical contributors to deepening folds.

3. Bone Resorption

A subtle but clinically significant change. The maxillary bone gradually remodels with age, reducing forward projection and allowing soft tissues to fold more sharply.

4. Repetitive Facial Movement

Smiling, speaking and eating create natural creases. Over decades, these repeated movements contribute to line etching.

5. Lifestyle and Environmental Stressors

  • UV exposure
  • Smoking
  • High pollution levels
  • Chronic stress

Each accelerates free radical damage, breaking down collagen and contributing to premature deepening.

How to Prevent or Slow Smile Lines

While nasolabial folds cannot be completely erased, consistent care can maintain skin resilience, hydration, and youthful midface contour.

Skincare Essentials

The skin’s structural integrity is central to the appearance of smile lines. Collagen, elastin, and hyaluronic acid decline with age, leading to thinner, less elastic skin. A carefully curated skincare routine strengthens these key components and slows the deepening of folds.

  • Sun Protection: Daily use of broad-spectrum SPF is the single most important preventive measure. UV radiation breaks down collagen and elastin and accelerates dermal thinning. Consistent sun protection preserves midface volume, prevents fine lines from forming, and supports skin elasticity over decades.
  • Retinoids: Retinoids, including prescription-strength tretinoin or gentler over-the-counter derivatives, stimulate collagen synthesis and increase dermal thickness. Regular use can reduce early signs of folding, improve skin texture, and restore firmness to the midface.
  • Antioxidants: Ingredients such as vitamin C, niacinamide, and resveratrol neutralise free radicals, which are unstable molecules that accelerate skin ageing. Antioxidants help maintain dermal integrity, support collagen, and reduce oxidative stress caused by UV exposure, pollution, and lifestyle factors.
  • Hyaluronic Acid and Moisturisers: Hydration is fundamental. Hyaluronic acid attracts and retains water in the dermis, maintaining skin plumpness. Well-hydrated skin is more resilient to folding and appears smoother, reducing the visibility of nasolabial lines. Regular moisturisation complements hyaluronic acid’s effects and supports the skin barrier.
  • Peptides: Bioactive peptides signal skin cells to produce collagen and elastin, strengthening dermal structure over time. Incorporating peptide formulations can improve skin firmness, texture, and long-term resilience against smile line formation.

Lifestyle Optimisation

Skincare alone cannot prevent smile lines. External and internal factors profoundly influence collagen health, skin elasticity, and midface volume.

  • Avoid Smoking: Smoking accelerates collagen breakdown and reduces microcirculation, impairing the skin’s repair mechanisms. Smokers often develop deeper nasolabial folds at an earlier age.
  • Hydration: Consistent water intake helps maintain skin turgor and reduces the appearance of fine lines. Dehydration compromises elasticity and makes folds more noticeable.
  • Nutrition: A nutrient-rich, antioxidant-heavy diet supports skin structure from the inside out. Vitamins C and E, zinc, omega-3 fatty acids, and polyphenols all contribute to collagen integrity, hydration, and protection against oxidative stress.
  • Sleep and Stress Management: Quality sleep supports cellular repair and collagen production. Chronic stress increases cortisol, which contributes to oxidative damage and tissue breakdown. Practices such as yoga, meditation, or regular exercise can reduce stress-induced ageing.

Gentle Facial Massage

Targeted facial massage can support circulation, lymphatic drainage, and muscle tone, which helps maintain midface lift.

  • Perform light, upward, and outward movements on the cheeks and around the mouth.
  • Massage should be gentle and controlled; aggressive or forceful manipulation can stretch already compromised tissue and worsen lines.
  • Consider combining massage with hydrating creams or serums to reduce friction and enhance absorption of active ingredients.

Non-Surgical Treatments for Nasolabial Folds

As nasolabial folds deepen, professional interventions can provide refined, natural-looking results. The most effective approaches restore midface volume, improve skin quality, and support facial structure. Among these, nasolabial filler offers a quick, cost-efficient, and highly impactful solution for softening smile lines.

Nasolabial Filler

Hyaluronic acid fillers are widely recognised as the most reliable non-surgical option for addressing nasolabial lines. Modern techniques go beyond simply filling the crease—they restore underlying midface support, lifting the cheeks and enhancing natural facial contours.

Why choose nasolabial filler:

  • Immediate lift and softening of folds
  • Restoration of midface volume, providing natural structure
  • Hydration and skin quality improvement
  • Subtle stimulation of collagen, supporting longer-term results

Results refine over one to two weeks and typically last 9–18 months, depending on individual factors and product choice.

At Dr Hass Clinic, every filler treatment is performed with anatomical precision and aesthetic artistry. Each plan is fully personalised to your facial structure, ensuring balanced, natural results that preserve expression.

Other Non-Surgical Options

While nasolabial filler remains the most effective and efficient solution for softening smile lines, several complementary treatments can enhance results and maintain youthful skin quality. These options are often combined with filler for a refined, balanced outcome:

  • Botulinum Toxin: Targeted, low-dose injections can relax muscles around the mouth, reducing excessive pull that contributes to deepening folds over time. This approach helps prevent further crease formation and smooths the lower-face profile.
  • Skin Boosters: Designed to improve hydration, skin texture, and luminosity, skin boosters are ideal for patients seeking overall facial rejuvenation alongside volume restoration. They enhance the skin’s suppleness, giving a subtle plumpness and glow.
  • Laser, Radiofrequency, and Endolift® Treatments: Energy-based therapies stimulate collagen production and tighten the skin, improving elasticity and firmness. They are particularly effective for mild to moderate nasolabial folds or when used as an adjunct to filler. Endolift®, a minimally invasive laser technique, targets deeper tissue layers, supporting midface lift and volumisation while refining skin texture for a naturally youthful appearance.

By combining these treatments strategically, it is possible to address both the folds themselves and the surrounding skin quality, achieving results that are natural, balanced, and long-lasting.

Surgical Solutions

For patients with advanced facial ageing, surgical options such as facelift or fat grafting provide longer-lasting structural improvement. These procedures are typically reserved for individuals whose concerns go beyond what non-surgical treatments can achieve.

Even with surgery, filler often remains an important complement, refining contours and restoring youthful midface lift without overcorrection.

Conclusion

Nasolabial folds are a natural part of facial expression, but they do not have to define your appearance. With a combination of preventive skincare, lifestyle optimisation, and professional treatments, it is possible to maintain a youthful, balanced midface contour and soften smile lines effectively.

Among available options, nasolabial filler offers the most immediate, cost-efficient, and long-lasting improvement. At Dr Hass Clinic, every treatment is delivered with precision, expertise, and personalised care, ensuring results that are natural, elegant, and tailored to your facial structure.

Investing in the right combination of skincare, lifestyle, and professional treatments ensures that your smile lines remain subtle, supported, and harmonious with the rest of your face.

FAQs

Can nasolabial folds be completely removed?

While they cannot be erased entirely, their appearance can be significantly softened with treatments such as nasolabial filler, skin boosters, and laser or radiofrequency therapy. Preventive skincare and lifestyle measures also slow progression.

How long do nasolabial filler results last?

Results typically last 9–18 months, depending on the product used, individual anatomy, and lifestyle factors. Fillers restore volume and lift, offering immediate improvement while subtly stimulating collagen over time.

Are nasolabial fillers safe?

Yes, when administered by a trained, experienced practitioner. At Dr Hass Clinic, all treatments are performed by Dr Hasaneen Al Janabi, a Royal College of Surgeons member with expertise in advanced facial anatomy, ensuring safe, natural-looking results.

Which treatment is best for deep nasolabial folds?

For most patients, nasolabial filler provides the most effective and efficient solution. Other options, like botulinum toxin, skin boosters, and energy-based devices, can complement filler or suit milder folds.

Can lifestyle changes reduce smile lines?

Yes. Daily sun protection, consistent hydration, a nutrient-rich diet, restorative sleep, and stress management all contribute to maintaining skin resilience and midface contour.

What is the difference between nasolabial folds and marionette lines?

It is important to distinguish between different lower-face lines:

  • Nasolabial folds run from the sides of the nose to the corners of the mouth.
  • Marionette lines extend from the corners of the mouth toward the chin.

Understanding these differences ensures that treatments address the underlying cause rather than simply targeting the visible crease.

Would highly recommend the Dr Hass Clinic. From booking my initial consultation right through to aftercare, every interaction has been quick, easy and professional. After having Endolift on my face with exceptional results, I had no hesitation in booking an Endolift body treatment for my thighs. Due to the amount of loose skin, I had always assumed surgery was my only option. I didn’t want to trade sagging skin for scars, and I also didn’t have the budget or the time for surgery and a lengthy recovery. I was therefore over the moon when Dr Hass explained that I could achieve visible skin tightening results with Endolift. I’ve just had the treatment, so I’m now really excited to see the results develop! The level of care, expertise and attention throughout has been brilliant. I’m particularly self-conscious about my thighs, but Dr Hass made me feel completely at ease and comfortable throughout the consultation and treatment. The treatment itself was also practically pain-free. I genuinely wouldn’t hesitate to recommend Dr Hass and his clinic. He clearly knows his stuff, takes great care of his patients and, as an added bonus, is actually a really cool guy to spend a few hours, I’m now a country music fan too!

I am so lucky to have found Dr. Hass. I recently did an Endolift procedure on my body and couldn't be happier that I chose to go with this clinic. I first had a consultation where Dr. Hass went through the whole procedure in detail and made me feel heard. I then came in for the actual procedure, feeling quite anxious as I never had anything similar done. The procedure went through so smoothly, and the pain was very minimal. Dr. Hass ensured I felt comfortable, and was very patient with me the entire time. He is definitely at the top of his field, so I felt safe being in his hands. I'm still in the process of recovery but I have minimal bruising and swelling and everything is healing really well. I already told Dr. Hass that I will come to him for any future procedure or cosmetic enhancement!

I visited Dr. Hass for a non-surgical nose treatment and I couldn't be happier with the results. My nose was lifted instantly and the whole procedure was very quick and painless. I don't live in the UK, but I would absolutely travel back to London to have this treatment done again. I highly recommend Dr. Hass

I had a really nice consultation. He took the time to explain everything clearly and answered all of my questions, which made me feel really comfortable. I also liked that he recommended a treatment that actually suited my age, my skin, and my facial structure instead of just suggesting anything. I think that’s really important because everyone’s face is different. Overall, I had a great experience and would definitely recommend him.

Dr. Hass was absolutely amazing! I had an Endolift laser treatment with him, and I couldn't be happier with my experience. He was incredibly attentive, took the time to listen to all my questions, and always responded to my messages straight away, which made me feel really cared for throughout the whole process. He offers great prices, the clinic is beautiful, friendly and welcoming. The atmosphere is relaxed and professional, making every visit a pleasure. It's only been two weeks since my treatment, and I'm already so impressed with the results. My face looks more lifted, refreshed, and defined, and I've had people commenting on how good my skin looks. Knowing that the full results continue to develop over the next three months makes me even more excited to see the final outcome. I was so impressed that I brought my mum and sister with me, and they both loved their treatments too! I honestly can't recommend Dr. Hass enough. If you're thinking about having Endolift, I highly recommend him. Thank you for such an amazing experience—I can't wait to come back for more treatments!

I can’t recommend Dr Has enough. I visited his clinic on Harley Street for tear trough filler / skin tightening, and the whole experience was excellent from start to finish. The tear trough results were instant. I noticed the difference straight away and couldn’t be happier. Dr Has is genuinely friendly and incredibly professional. He took the time to explain everything, made me feel completely at ease, and made sure the entire process was smooth and comfortable. It’s clear he really knows his craft and cares about getting the best results for his patients. If you’re considering any aesthetic treatments, this is the place to go. Thank you Dr Has!

I wanted a subtle, natural look, and he achieved exactly what I was hoping for. I would highly recommend Dr Hass to anyone considering aesthetic treatments, especially if it’s your first time.
