Lines stretching from the sides of your nose to the corners of your mouth, called nasolabial folds or smile lines, are a natural part of your facial anatomy. As the creases deepen, however, they become among the most common concerns we hear about from women and men.
If your smile lines appear more noticeable and you’re researching ways to minimize them, dermal fillers such as JUVÉDERM® products are a go-to choice at our practice. We offer a range of effective treatment options, rather than a one-size-fits-all approach.
What Causes Smile Lines?
Understanding why smile lines develop is one key to choosing the right treatment. These folds form due to a combination of:
- Aging and collagen loss, which reduces skin firmness
- Volume loss in the midface, causing tissues to descend
- Repetitive facial movement, such as smiling and talking
- Skin quality changes, including decreased elasticity
Although everyone has nasolabial folds, they become more noticeable as the skin thins and facial volume shifts with age.
At What Age Do Smile Lines Appear?
The answer varies. Subtle lines can begin forming in your late 20s or early 30s, especially with expressive facial movement. However, deeper folds typically become more prominent in your 40s and beyond, as collagen loss accelerates and facial fat shifts downward.
How To Get Rid of Smile Lines
Dermal fillers are one of the most effective nonsurgical options. Unlike neuromodulators such as BOTOX®, which relax muscles, fillers restore lost volume and support the surrounding tissue structure.
Dermal fillers are often the first-line treatment for nasolabial folds because they can:
- Smooth deep creases
- Restore youthful contours
- Deliver immediate, visible improvement
- Require little to no downtime
Best Fillers for Nasolabial Folds
Not all fillers are the same. The best choice depends on your anatomy, skin quality, and the severity of your folds. Here are the most commonly used options:
Hyaluronic Acid (HA) Fillers
Hyaluronic acid is a substance that is naturally present in the human body. Some people apply hyaluronic acid to the skin to heal wounds, burns, skin ulcers, and as a moisturizer.
Popular HA fillers include JUVÉDERM, Restylane®, and BELOTERO BALANCE®. These fillers are the most widely used for smile lines because they are:
- Soft and flexible for natural movement
- Reversible if needed
- Hydrating, helping plump the skin
HA fillers are considered the gold standard for nasolabial folds and typically last 6 to 18 months. They are pre-mixed with lidocaine, a local anesthetic, to enhance comfort during the injections.
Biostimulators
Biostimulators such as Sculptra® work differently than most injectable fillers. Rather than instantly filling the fold with a gel, it uses poly-L-lactic acid (PLLA) to stimulate your body’s natural collagen production in the deeper layers of the skin, with results lasting up to 2 years.
By rebuilding collagen over time, Sculptra:
- Gradually fills in volume beneath the folds
- Thickens the skin to smooth out wrinkles
- Supports the surrounding tissue for improved facial contour
- Softens the transition between the cheeks and the mouth
When treating nasolabial folds, our providers use small, precise injections along the length of the crease and into adjacent areas of volume loss. The injections are placed in the deep dermis or subcutaneous layer, where they stimulate fibroblast activity and encourage collagen remodeling.
Technique Matters
While selecting the best filler is important, choosing the right injector is even more critical. Proper technique minimizes risks and ensures natural-looking results. Complications are rare but can occur if fillers are placed incorrectly, underscoring the importance of expertise.
Can I Smile After Nasolabial Filler?
Yes, when you select an expert injector. Minimizing smile lines doesn’t mean minimizing your smile. Modern fillers are designed to integrate with your natural tissue, allowing for normal facial movement. The goal is to soften lines while preserving your natural expressions, not eliminate them.
