Nasolabial Folds: Causes, Treatment Options and Dermal Filler Solutions
What Are Nasolabial Folds?
Nasolabial folds are the natural creases that run from the sides of your nose down to the corners of your mouth. Often called smile lines or laugh lines, nasolabial folds are present in everyone but become more pronounced with age as skin loses volume and elasticity. While these folds are a normal part of facial anatomy, deeper nasolabial folds can create a tired or aged appearance that many people wish to soften.
As we age, the fat pads in our face shift downward and collagen production slows, causing the skin in the midface to lose support. This creates more prominent nasolabial folds that remain visible even when the face is at rest. The depth and visibility of nasolabial folds vary from person to person based on genetics, lifestyle, and natural facial structure.
What Causes Nasolabial Folds to Deepen?
Several factors contribute to the development and deepening of nasolabial folds over time:
- Volume loss: Fat and collagen in the cheeks decrease with age, reducing midface support
- Skin elasticity: Loss of elastin makes skin less able to bounce back after movement
- Repeated facial expressions: Smiling and talking create natural creases that deepen over years
- Sun exposure: UV damage breaks down collagen and accelerates skin aging
- Genetics: Some people are predisposed to more prominent facial folds
Treatment Options for Nasolabial Folds
Common approaches to softening nasolabial folds include:
- Dermal fillers to restore volume and support
- Collagen-stimulating treatments to improve skin quality
- Skin tightening procedures to enhance firmness
- Medical-grade skincare to support collagen production
- Combination therapies for comprehensive facial rejuvenation
Dermal Fillers for Nasolabial Folds
Dermal fillers are the most popular and effective non-surgical treatment for nasolabial folds. Hyaluronic acid fillers are injected directly into or around the folds to add volume, lift sagging tissue, and smooth the crease. Results are immediate and typically last between six months to two years depending on the product used and individual factors.
The treatment is performed in-office with minimal downtime. Your provider may inject filler directly into the nasolabial fold or into the cheeks to restore midface volume and reduce the appearance of the fold from above.
