Anatomical feature of the human face

Nasolabial fold[edit]

The nasolabial fold is a prominent facial feature that extends from the sides of the nose to the corners of the mouth. These folds are also commonly referred to as "smile lines" or "laugh lines" due to their tendency to become more pronounced when a person smiles or laughs.

Anatomy[edit]

The nasolabial fold is formed by the underlying muscles and fat pads of the face. It is primarily influenced by the zygomaticus major and zygomaticus minor muscles, which are responsible for elevating the corners of the mouth. The fold itself is a natural crease in the skin that becomes more defined with age due to the loss of collagen and elastin, as well as the redistribution of facial fat.

Function[edit]

While the nasolabial fold is often considered a cosmetic concern, it also plays a functional role in facial expression. The fold allows for a greater range of motion in the upper lip and cheeks, facilitating expressions such as smiling, laughing, and speaking. The presence of the fold also contributes to the overall contour and shape of the face.

Aging and the Nasolabial Fold[edit]

As individuals age, the nasolabial fold tends to deepen and become more pronounced. This is due to several factors, including:

Loss of skin elasticity
Decrease in subcutaneous fat
Gravity
Repeated facial expressions

The deepening of the nasolabial fold is a common sign of aging and is often addressed in cosmetic surgery and dermatology through procedures such as dermal fillers, facelifts, and laser resurfacing.

Cosmetic Treatments[edit]

Various treatments are available to reduce the appearance of nasolabial folds. These include:

Dermal Fillers: Injectable substances such as hyaluronic acid are used to fill in the fold and smooth the skin.
Facelift Surgery: A surgical procedure that tightens the skin and underlying tissues to reduce the appearance of folds and wrinkles.
Laser Resurfacing: A technique that uses laser technology to improve skin texture and reduce wrinkles.

-'''Nasolabial fold''' is a term used in [[anatomy]] to describe the skin creases that run from each side of the nose to the corners of the mouth. These folds, also known as "smile lines" or "laugh lines," are a normal part of the human face and become more prominent with age due to the loss of [[collagen]] and [[elastin]] in the skin.

+==Aging and the Nasolabial Fold==
-As a person ages, the skin loses its elasticity and volume, leading to the deepening of the nasolabial folds. This is due to the decrease in the production of collagen and elastin, two proteins that provide structure and elasticity to the skin. In addition, the fat pads in the face, which provide volume, begin to shift downward, further accentuating the nasolabial folds.
+As individuals age, the nasolabial fold tends to deepen and become more pronounced. This is due to several factors, including:
+* Loss of skin elasticity
+* Decrease in subcutaneous fat
+* Gravity
+* Repeated facial expressions

+The deepening of the nasolabial fold is a common sign of aging and is often addressed in [[cosmetic surgery]] and [[dermatology]] through procedures such as [[dermal fillers]], [[facelifts]], and [[laser resurfacing]].
-There are several treatment options available to reduce the appearance of nasolabial folds. These include [[dermal fillers]], which are injected into the skin to add volume and smooth out the folds; [[laser resurfacing]], which uses light energy to stimulate collagen production; and [[facelift surgery]], which tightens the skin and underlying muscles to reduce the appearance of the folds.
