How Do Nasolabial Folds Form? Understanding Nasolabial Folds and How to Eliminate Them
As skin ages, it not only shows fine lines, rough texture, dullness, and enlarged pores, but it also experiences a loss of collagen, which leads to sagging and looseness of tissues. One of the most troublesome areas affected by this process is the "nasolabial folds." Once these folds deepen, they can often be the most aging part of the face. So, why do massaging or applying skincare products to the nasolabial folds not seem to work?
The key to improving nasolabial folds lies in first understanding what type they are and what causes them. Whether you're aiming to lighten these lines or seeking a more youthful skin appearance, don't miss this comprehensive guide on nasolabial folds. Let's explore how to say goodbye to nasolabial folds easily.

Understanding the Causes of Nasolabial Folds
How Do Nasolabial Folds Form?
Nasolabial folds refer to the wrinkles that run from the sides of the nose to the corners of the mouth. Several common factors contribute to their formation:
- Facial Muscle Movement: Repeated facial expressions, such as smiling or frowning, can lead to the development of wrinkles in these areas over time.
- Skin Aging: As we age, the skin gradually loses its elasticity, and the collagen and elastin fibers in the skin decrease, making it more prone to wrinkle formation.
- Sun Exposure: Prolonged exposure to the sun accelerates skin aging, which also contributes to the formation of nasolabial folds.
- Smoking: Smoking can impair blood circulation to the skin, speeding up skin aging and increasing the likelihood of wrinkles, including nasolabial folds.
- Genetic Factors: An individual's genetics can also play a role in the formation of nasolabial folds. Some people are naturally more prone to developing wrinkles in this area.
Three Types of Nasolabial Folds
After gaining a basic understanding of nasolabial folds, we can categorize them into the following three types based on their causes:
-
Skeletal-Type Nasolabial Folds People with naturally prominent cheekbones often have deeper nasolabial folds due to the greater height difference between the cheeks and the mouth. This type of nasolabial fold is known as the "sunken nasolabial fold" or "skeletal-type nasolabial fold," and it commonly occurs in individuals with prominent cheekbones or those who have concerns about protruding teeth.

Muscle-Type Nasolabial Folds Muscle-type nasolabial folds are caused by frequent facial muscle movements, such as excessive smiling or making exaggerated expressions that stretch the facial muscles. These repetitive actions can lead to the formation of nasolabial folds, and over time, may even result in raised, ridged areas along the fold.

Aging-Type Nasolabial Folds Aging-type nasolabial folds primarily result from the loss of collagen due to aging, which causes the skin to lose its firmness and elasticity. As a result, the skin sags, and the nasolabial folds become deeper and more prominent. This type is the most common in the medical aesthetics market, as it is a natural consequence of the aging process.

Difference Between Nasolabial Folds and Marionette Lines
- Nasolabial Folds: These lines extend from the sides of the nose to the corners of the mouth.
- Marionette Lines: These wrinkles appear at the corners of the mouth and extend downward toward the chin area.

How to Improve and Maintain Nasolabial Folds
- Reduce UV Exposure: To prevent further aging of the skin, it’s important to apply sunscreen whenever outdoors to protect your skin from UV rays.
- Enhance Skin Hydration: Choose skincare products with sufficient moisturizing ingredients like hyaluronic acid and collagen to keep your skin hydrated and plump.
- Avoid Rapid Weight Loss: Quick weight loss can lead to a decrease in collagen and subcutaneous fat, which may cause the face to lose volume, making nasolabial folds more noticeable.
- Eat Nutritious Foods: Incorporate foods rich in protein and vitamin C into your diet. These nutrients support collagen production and skin health.
- Facial Massage: Use your fingers or a massage tool to gently pull along the nasolabial fold area in an upward and outward motion. This helps stimulate lymphatic circulation, reduce sagging, and smooth out wrinkles.
Cosmetic Treatments to Eliminate Nasolabial Folds
- Hyaluronic Acid: A commonly used filler to improve nasolabial folds, hyaluronic acid is injected into the skin's subcutaneous layer to fill in the hollows, restoring a hydrated and plump appearance.
- Collagen Stimulators: Products like Ellanse, Yvoire, Restylane, and Sculptra stimulate collagen production in addition to filling and supporting the skin. These treatments not only fill the folds but also promote long-lasting results by encouraging collagen regeneration.
2. Botox Injections:
Botox can be injected into the nasolabial fold area to relax the muscles between the upper lip and nostrils. This helps reduce the overactive muscle lines, softening the folds and improving the appearance of muscle-driven nasolabial wrinkles.
3.Radiofrequency / Ultrasound Lifting Treatments:
These treatments, such as the popular Phoenix RF, use heat energy to stimulate collagen production, tightening the skin and improving elasticity. In addition to smoothing nasolabial folds, radiofrequency and ultrasound therapies can firm up the skin and reduce sagging, offering a dual benefit for aging-related nasolabial wrinkles.
