What Is Nasolabial Fold Filler?

Nasolabial fold filler is an injectable treatment that improves the appearance of the lines running from the sides of the nose to the corners of the mouth.

It is commonly used for:

• Deep smile lines
• Nasolabial folds
• Age-related facial volume loss
• Midface volume deficiency
• Early facial aging
• Tired facial appearance
• Facial rejuvenation

Rather than treating only the crease, dermatologists often evaluate the entire midface because cheek volume loss frequently contributes to deeper nasolabial folds.

How Nasolabial Fold Filler Works

Dermal filler is strategically placed to restore facial support and soften the fold.

Treatment may help:

• Reduce the depth of smile lines
• Restore midface support
• Improve facial balance
• Soften facial shadows
• Create smoother facial contours
• Rejuvenate the lower face

Depending on facial anatomy, filler may be placed in the cheeks, directly within the fold, or both.

Nasolabial Fold Filler for Smile Lines

Smile lines naturally become deeper with age because of:

• Collagen loss
• Facial fat loss
• Skin laxity
• Bone remodeling
• Repeated facial movement

Careful filler placement may soften the fold while preserving natural facial expression.

Types of Fillers

Depending on your facial anatomy, the clinic may recommend:

• Hyaluronic acid fillers
• Calcium hydroxylapatite fillers
• Collagen-stimulating fillers

Hyaluronic acid fillers are commonly chosen because they provide immediate results and can generally be dissolved if medically necessary.
