Joy is one of the most natural and beautiful emotions. Nothing radiates more than a smile. However, years of laughter and expression can put pressure on the skin and soft tissue causing unwanted lines to form, especially around the mouth. 

There are many types of wrinkles, creases and folds in this area, but a few common and often bothersome are: smile lines, or nasolabial folds that extend from the nose to the upper corner of the mouth; lip lines sometimes referred to as smoker or barcode lines; marionette lines that reach from the corners of the mouth down toward the chin and cause a frowning or unhappy appearance; and dimples or creases on the chin. One of the most effective, non-surgical treatments available today is dermal fillers for smile lines.

What Are Dermal Fillers and How Do They Work?

Dermal fillers are injectable treatments that restore lost volume, smooth wrinkles, and enhance facial contours. Whether used for smile lines, lips, or cheeks, fillers contain substances like hyaluronic acid (HA) that boost skin hydration and elasticity. When expertly injected, dermal fillers provide immediate volume to areas that have lost collagen due to aging. Some fillers even stimulate your body’s natural collagen production, leading to long-term improvements.

Most dermal fillers show results right away, with effects lasting anywhere from 6 months to 2 years, depending on the type used. Regular maintenance can keep your results looking fresh and youthful.

What’s in Dermal Fillers?

Dermal fillers are made from biocompatible substances, each offering unique benefits:

• Hyaluronic Acid (HA): Naturally hydrates and plumps the skin.
• Calcium Hydroxylapatite (CaHA): Provides structure and stimulates collagen production.
• Poly-L-Lactic Acid: Encourages long-term collagen growth for extended results.
• Polymethylmethacrylate (PMMA): A semi-permanent filler that offers structural support.
• Autologous Fat: Uses your own fat cells for natural, long-term volume restoration.

Smile lines are a natural part of aging, but if you’re looking for a smoother and rejuvenated appearance, dermal fillers offer a safe and effective solution. By seeing one of our skilled injectors and choosing the right filler, you can achieve long-lasting, natural-looking results. 

What are the Types of Dermal Fillers for Smile Lines and How Long Do They Last?

The most commonly used dermal fillers for smile lines include:

• Hyaluronic Acid (HA) Fillers (e.g., Juvederm, Restylane, RHA Redensity): Lasts up to 12 months, providing natural hydration and volume.
• Calcium Hydroxylapatite (CaHA) Fillers (e.g., Radiesse): Last up to 12 months, offering firmer structural support.
• Poly-L-Lactic Acid Fillers (e.g., Sculptra): Stimulate collagen production, with results lasting up to 12 months.
• Autologous Fat Transfer: Uses your own fat for long-lasting volume but requires a minor surgical procedure.

Individual metabolism and body chemistry can affect how long fillers last, so these timeframes are approximate and may vary from person to person. Most fillers gradually break down, requiring maintenance treatments for sustained results.

Are Dermal Fillers Permanent?

Most dermal fillers are not permanent, as they gradually break down and are absorbed by the body. Regular maintenance treatments may be needed to sustain the desired effects. The only longer-term solution is autologous fat transfer, which can last for several years but requires a more invasive procedure.

Are Dermal Fillers Safe?

Yes, dermal fillers are FDA-approved and considered safe when administered by a qualified professional. However, like any cosmetic procedure, there are some potential side effects:

• Temporary swelling, redness, or bruising
• Lumps or uneven texture (which can be corrected with massage or touch-ups)
• Rare complications such as infection or vascular occlusion
