Nasolabial Fold Formation
Skin Elasticity Changes
Nasolabial folds are those lines that run from the sides of your nose to the corners of your mouth, also known as “smile lines.” Their prominence increases with age, leading to a perception of aging.
The primary reason for their deepening is the loss of elasticity in the skin. As we age, our bodies produce less collagen and elastin, the proteins responsible for keeping skin supple and firm.
Collagen provides structural support, giving skin its strength and shape, while elastin allows it to stretch and return to its original form.

This decline in collagen and elastin production begins gradually in our mid-20s and accelerates with time. The result is thinner, less resilient skin that loses its ability to bounce back, leading to the formation of wrinkles and folds, including nasolabial folds.
Several other factors contribute to the development of deeper nasolabial folds, such as:
-
Facial expressions: Repeated smiling, frowning, and talking can etch lines into the skin over time, making nasolabial folds more prominent.
-
Sun exposure: UV radiation damages collagen and elastin fibers, accelerating skin aging and deepening wrinkles.
-
Smoking: Nicotine constricts blood vessels, reducing blood flow to the skin and hindering its ability to repair itself. This contributes to premature aging and wrinkle formation.
-
Genetics: Some people are genetically predisposed to having thinner skin and less collagen production, making them more susceptible to wrinkles and nasolabial folds.
Understanding the factors influencing nasolabial fold formation can help us make informed decisions about skincare and lifestyle choices to minimize their appearance and maintain a youthful appearance.
Facial Muscle Movement
Nasolabial folds, those creases that run from the bottom of each nostril to the corner of the mouth, are a natural part of facial anatomy.
They become more prominent with age due to a combination of factors. As we age, our skin loses elasticity and collagen production slows down. This causes the skin to thin and sag, making nasolabial folds appear deeper.
Facial muscles also play a role in their formation. Over time, repeated muscle movements, such as smiling, frowning, and talking, can cause these areas to crease and deepen, leading to more noticeable nasolabial folds.
The **orbicularis oculi** muscle, which circles the eye, plays a significant role in this process. When we smile or laugh, this muscle contracts, pulling down on the corners of the mouth and contributing to the formation of nasolabial folds.
Similarly, the **zygomaticus major** muscle, responsible for raising the corners of the mouth, also contributes to their appearance during expressions.
The levator labii superioris and depressor labii inferioris muscles, involved in lifting and lowering the upper lip, respectively, can also influence the prominence of nasolabial folds.
Furthermore, genetics, sun exposure, and lifestyle factors like smoking can all contribute to their development.
Fat Loss & Redistribution
Nasolabial folds are those creases that run from the base of your nose to the corners of your mouth. They are a natural part of facial anatomy, but their prominence often increases with age.
Several factors contribute to this deepening. As we age, our skin naturally loses collagen and elastin, proteins that provide structure and support. This loss leads to thinner, less elastic skin, allowing the underlying fat pads to sag more noticeably.
Additionally, facial muscles weaken over time, reducing their ability to lift the cheeks and maintain the fullness around the nose. The supporting tissues also lose volume, further accentuating the folds.
Fat redistribution also plays a role. Our bodies tend to store fat differently as we age. While some areas may experience increased fat deposits, others may see a decrease. This can lead to a loss of volume in the cheeks, making the nasolabial folds appear more pronounced.
Sun exposure contributes to skin aging and breakdown of collagen and elastin, further exacerbating the appearance of nasolabial folds. Lifestyle factors like smoking and dehydration also impact skin health and can worsen their prominence.
Genetics also influences the depth and development of nasolabial folds. Some individuals are naturally predisposed to more pronounced folds, regardless of age.
While aging is a natural process that inevitably affects facial features, various strategies can help minimize the appearance of nasolabial folds. These include maintaining a healthy lifestyle with sun protection, hydration, and a balanced diet, incorporating facial exercises, and considering cosmetic procedures like fillers or lasers for targeted volume restoration.
Contributing Factors to Nasolabial Fold Deepening with Age
Genetics
Nasolabial folds, those creases that run from the sides of the nose to the corners of the mouth, are a common feature that deepens with age. This change is influenced by a complex interplay of factors, including genetics, collagen and elastin breakdown, sun damage, facial muscle actions, and lifestyle choices.
Genetics plays a significant role in determining the initial depth and prominence of nasolabial folds. Some individuals inherit naturally deeper folds due to their bone structure, skin thickness, and underlying fat distribution.
As we age, our bodies produce less collagen and elastin, two proteins crucial for maintaining skin’s elasticity and firmness. This decline begins in our 20s and accelerates with time, leading to sagging and deepening of facial features, including the nasolabial folds.
Repeated exposure to ultraviolet (UV) radiation from the sun damages the collagen and elastin fibers in the skin, further contributing to wrinkles and fold formation. Sun damage is a significant factor in accelerating the aging process of the skin.
The muscles responsible for facial expressions, such as smiling, frowning, and talking, can also contribute to nasolabial fold deepening over time. These repetitive movements create creases in the skin, which become more pronounced with age due to reduced collagen and elastin.
Lifestyle factors like smoking, poor diet, lack of sleep, and stress can exacerbate the aging process and worsen nasolabial folds. Smoking damages collagen and elastin, while a poor diet lacks essential nutrients for healthy skin.
In addition to these factors, volume loss in the cheeks and midface as we age can also contribute to the prominence of nasolabial folds. This happens because the supporting structure weakens, causing the skin to sag and accentuate the creases.
Sun Exposure
Nasolabial folds, those creases that run from the base of the nose to the corner of the mouth, are a natural part of facial anatomy. However, they often become more prominent with age due to a combination of factors.
One primary contributor is **facial fat loss**. As we age, our skin and underlying tissues naturally lose volume. This loss is particularly noticeable in the midface region, causing the cheeks to sag and making the nasolabial folds appear deeper.
**Collagen and elastin degradation** also play a role. These proteins provide structure and elasticity to the skin. Over time, their production slows down and they break down, leading to wrinkles and sagging skin, including the nasolabial folds.
Sun exposure is another significant factor in deepening nasolabial folds. UV radiation damages the collagen and elastin fibers in the skin, accelerating their breakdown and contributing to wrinkles and sagging. The repeated contraction of facial muscles from squinting or smiling also contributes to the development of lines around the nose and mouth.
Genetics also influences the prominence of nasolabial folds. Some individuals are predisposed to more pronounced folds due to their bone structure or skin thickness.
Lifestyle factors such as smoking, dehydration, and poor diet can also contribute to premature skin aging and deeper nasolabial folds.
Smoking
Nasolabial folds, those creases extending from the base of the nose to the corners of the mouth, are a natural part of facial anatomy. However, they tend to deepen and become more prominent with age.
Several contributing factors play a role in this process:
**Facial Fat Redistribution:** As we age, our bodies lose subcutaneous fat, particularly in the face. This loss results in facial sagging and thinning, causing nasolabial folds to appear deeper.
Muscle Atrophy: The muscles that support facial structure naturally weaken with time. This can lead to a reduction in cheek volume and contribute to the prominence of nasolabial folds.
**Skin Elasticity Loss:** Collagen and elastin, proteins responsible for skin’s elasticity and firmness, decline with age. This makes the skin thinner and less able to bounce back, leading to more defined wrinkles and folds like nasolabial creases.
**Sun Damage: Excessive sun exposure breaks down collagen and elastin fibers, accelerating skin aging and deepening nasolabial folds. Sun damage also contributes to hyperpigmentation, making these creases more noticeable.
**Smoking:** Cigarette smoke contains harmful chemicals that damage collagen and elastin, hindering their production. Smoking significantly accelerates skin aging and contributes to deeper nasolabial folds.
Other factors influencing nasolabial fold deepening include genetics, lifestyle choices (e.g., diet, hydration), and repeated facial expressions like smiling or frowning over time.
Facial Expressions
Nasolabial folds, those creases that run from the bottom of the nose to the corners of the mouth, are a natural part of facial anatomy. However, they tend to become more pronounced as we age. This deepening is due to a combination of factors.
One key contributor is the gradual loss of collagen and elastin in the skin. Collagen provides structural support, while elastin gives skin its elasticity. As these proteins decline with age, the skin loses its ability to bounce back, causing folds and wrinkles to become more prominent.
Another factor is fat redistribution. As we get older, the subcutaneous fat deposits under the skin can shift and decrease in volume, particularly in the cheeks. This loss of volume accentuates the nasolabial folds, making them appear deeper.
Facial expressions also play a role. Repeated movements, like smiling, frowning, and talking, create grooves in the skin over time. While these lines soften when we relax, they become more defined with age as the supporting tissues weaken.
Finally, gravity takes its toll. As we age, the muscles that support our facial structure naturally weaken, causing the skin to sag and accentuate existing folds.
Minimizing the Appearance of Nasolabial Folds
Dermal Fillers
Nasolabial folds, those creases that run from the base of your nose to the corners of your mouth, are a natural part of aging. As we age, our facial tissues naturally lose volume and elasticity, leading to the deepening of these folds. This volume loss is primarily due to the depletion of collagen and elastin, proteins that provide structure and support to the skin.
Several factors contribute to the worsening appearance of nasolabial folds with age:
1. Loss of Facial Fat:** We naturally lose subcutaneous fat (the fat layer beneath the skin) as we get older. This loss is more prominent in the mid-face area, which includes the cheeks and areas surrounding the nose, exacerbating the appearance of nasolabial folds.
2. Skin Thinning:** As collagen and elastin decline, our skin becomes thinner and less resilient. This thinning allows wrinkles and folds to become more prominent.
3. Bone Resorption: With age, bone in the face can resorb, leading to a subtle decrease in facial structure. This can contribute to the deepening of nasolabial folds.
4. Gravity:** Gravity continuously pulls downwards on our facial tissues. Over time, this pull becomes more noticeable, accentuating existing wrinkles and folds, including nasolabial folds.
Fortunately, there are ways to minimize the appearance of these folds, such as dermal fillers.
Dermal fillers are injectable gels made from hyaluronic acid, a naturally occurring substance in our bodies that helps keep skin hydrated and plump. They work by adding volume to areas that have lost it, effectively filling in nasolabial folds and smoothing their appearance.
The results of dermal filler injections typically last between 6 months to 2 years, depending on the individual and the type of filler used. Multiple treatments may be needed to maintain desired results.
Other non-surgical options include:
• Radiofrequency (RF) Microneedling:** This treatment combines microneedles with radiofrequency energy to stimulate collagen production and tighten skin, reducing the appearance of wrinkles and folds.
• Chemical Peels:** Chemical peels exfoliate the skin, improving its texture and tone. While they may not dramatically reduce the depth of nasolabial folds, they can make them less noticeable by smoothing the surrounding skin.
• Laser Resurfacing:** This treatment uses lasers to remove damaged layers of skin and stimulate collagen production, leading to smoother and firmer skin.
Laser Resurfacing
Nasolabial folds, also known as smile lines, are creases that run from the bottom of your nose to the corners of your mouth. They become more prominent with age due to several factors.
As we age, our skin loses **collagen** and **elastin**, two proteins that provide structure and elasticity. This thinning and weakening of the skin allows the facial muscles to create deeper creases when we smile or express emotions.
Loss of subcutaneous fat also contributes to the deepening of nasolabial folds. As we age, our bodies naturally lose fat volume in various areas, including the face. This can cause the cheeks to sag and accentuate the appearance of the folds.
Sun damage plays a role as well. Ultraviolet (UV) radiation breaks down collagen and elastin fibers, accelerating the aging process and making nasolabial folds more pronounced.

While genetics can influence how prominent your nasolabial folds become, lifestyle factors can also impact their appearance.
Smoking
- Damages collagen and elastin fibers
- Reduces blood flow to the skin, hindering tissue regeneration
Excessive alcohol consumption can also dehydrate the skin and contribute to wrinkles.
Laser resurfacing is a cosmetic procedure that utilizes laser technology to remove damaged layers of skin and stimulate collagen production. It can be effective in minimizing the appearance of nasolabial folds by:
- Improving skin texture and tone
- Stimulating the growth of new collagen, tightening the skin
- Reducing the depth and prominence of wrinkles and folds
It is important to consult with a qualified dermatologist or plastic surgeon to determine if laser resurfacing is appropriate for you. They can assess your individual needs, discuss potential risks and benefits, and recommend the best treatment plan.
Lifestyle Modifications
Nasolabial folds, also known as smile lines or laugh lines, are creases that run from the sides of the nose to the corners of the mouth. They are a natural part of facial anatomy and become more prominent with age due to various factors.
While aging is a significant contributor, lifestyle choices can play a role in minimizing their appearance.
Here’s how you can make a difference:
**Sun Protection:** Excessive sun exposure damages collagen and elastin, leading to wrinkles and sagging skin. Apply broad-spectrum sunscreen daily with an SPF of 30 or higher, even on cloudy days.
**Hydration:** Staying hydrated from within helps plump the skin, reducing the appearance of fine lines and wrinkles. Aim for eight glasses of water per day.
**Healthy Diet:** A diet rich in antioxidants, vitamins C and E, and omega-3 fatty acids can support skin health and collagen production.
**Quit Smoking:** Smoking accelerates aging and damages the skin by constricting blood vessels, reducing oxygen supply, and breaking down collagen.
**Sleep Well:** During sleep, your body repairs and regenerates cells, including skin cells. Aim for 7-9 hours of quality sleep per night.
**Stress Management:** Chronic stress can contribute to premature aging. Engage in stress-reducing activities like yoga, meditation, or deep breathing exercises.
**Facial Exercises:** Certain facial exercises may help strengthen the muscles around the nose and mouth, potentially improving tone and reducing the appearance of nasolabial folds.
