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.

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.

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.

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.

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.
