Restylane Fillers for Smile Lines: How They Work and Results

Aging gracefully is a goal shared by many, yet time inevitably brings changes to the face — particularly around the mouth, where smile lines develop. These creases can deepen into nasolabial folds, altering the harmony of facial contours and creating a tired look. Fortunately, modern aesthetic medicine offers solutions that go beyond surface treatments. Among them, Restylane treatments stand out for their ability to smooth wrinkles and restore a youthful appearance without surgery.

This comprehensive guide explores how Restylane works to address nasolabial folds, marionette lines, and other common signs of aging. You’ll learn about Restylane Defyne, Refyne, and Lyft, understand what to expect from these treatments, and discover how individual results can rejuvenate your look naturally and effectively.

Understanding Smile Lines and Nasolabial Folds

Nasolabial folds are the deep lines running from the sides of the nose to the corners of the mouth. Everyone has them to some extent, but as we age, loss of collagen, fat, and elasticity makes these folds more pronounced. Repeated facial expressions, gravity, and decreased skin volume contribute to the deepening of these folds, resulting in noticeable wrinkles and sagging skin

Because nasolabial folds are located in dynamic areas of the face, treating them requires precision and an understanding of natural movement. Using the right type of dermal fillers is key to maintaining facial harmony and avoiding stiffness.

The Difference Between Smile Lines and Deep Laugh Lines

While smile and deep laugh lines both appear around the lips, smile lines are often more subtle and become visible primarily when you grin or laugh. As collagen diminishes, these lines can evolve into deeper nasolabial folds, creating a permanent crease even at rest.

Marionette Lines and Their Impact

Marionette lines extend downward from the corners of the lips toward the chin, contributing to a sagging or unhappy appearance. Combined with nasolabial folds, they can make the lower face appear heavier or more fatigued. Correcting both marionette lines and nasolabial folds together often produces the most balanced outcome.

What Are Restylane Dermal Fillers?

Restylane is a family of dermal fillers made with hyaluronic acid, a substance naturally found in the body that helps retain moisture and volume. By restoring lost volume, they smooth and fill wrinkles, rejuvenating facial contours.

Hyaluronic acid (HA) attracts water molecules, creating a gel-like structure that integrates into the skin’s tissue. This makes it ideal for treating nasolabial folds, marionette and lines around the mouth while maintaining a natural expression.

How Restylane Works

The filler is injected using a fine needle into the treated areas beneath the skin. Once injected, the gel provides support and lift, effectively reducing the depth of nasolabial folds. Depending on the product chosen (Restylane Defyne, Refyne, or Lyft) the consistency and flexibility of the gel vary to suit specific goals and facial movements.

Why Hyaluronic Acid Is Essential

Hyaluronic acid (HA) in Restylane is specifically formulated to mimic the natural substance produced by the body. This allows for seamless integration, ensuring smooth and hydrated results. Its benefits include:

  • Moisture retention for supple, elastic skin;
  • Biocompatibility, minimizing allergic reactions;
  • Ability to volumize cheeks and soften lines and nasolabial folds;
  • Gradual biodegradation, keeping results natural and safe.

Before any procedure, sharing your medical history helps ensure that the filler chosen matches your skin type and expectations.

Types of Restylane Products for Facial Wrinkles

Different Restylane products target different concerns. For nasolabial folds and marionette lines, the following formulations are particularly effective:

Restylane Defyne

It is designed for moderate to severe nasolabial folds and marionette lines. Its flexible structure, supported by Xpreshan technology, allows the filler to move naturally with your expressions. This makes Restylane Defyne ideal for dynamic areas of the face such as the mouth and chin.

By restoring volume, Restylane Defyne helps reduce deep wrinkles without compromising expression. It can also improve contour definition in the cheeks and chin, creating a more youthful look.

Restylane Defyne is often preferred by patients seeking long-lasting correction for nasolabial folds, delivering results that remain consistent for months. Because of its elasticity, Restylane Defyne maintains natural facial motion, avoiding a stiff appearance.

Restylane Refyne

It is slightly softer and best suited for moderate nasolabial folds and smile lines. Like Defyne, it utilizes Xpreshan technology to adapt to facial movement. The filler provides gentle support and elasticity, allowing patients to retain natural expressions while achieving smoothing smile lines.

Restylane Refyne offers a balance of flexibility and volume, ideal for those who want refined correction rather than dramatic change. Many patients prefer Restylane Refyne for early signs of aging or when lines and nasolabial folds are just beginning to appear.

Restylane Lyft

For more pronounced nasolabial folds and volume loss in the cheeks, Restylane Lyft provides a firmer lift. It’s also used to restore fullness to hollow cheeks, redefine the chin, and enhance the nose area when subtle contouring is desired.

Because of its structure, Lyft can support the overlying tissue and smooth even deeper creases. Many patients combine it with different treatments for comprehensive rejuvenation of the mid and lower face.

Restylane Silk

While primarily designed for enhancing lips, Restylane Silk can also improve vertical lines and wrinkles around the mouth. It’s a versatile option for patients who want to address both volume and surface texture.

The Treatment Process

Before receiving Restylane injections, you’ll meet with a qualified provider, often plastic surgeons or trained aesthetic specialists, to discuss your goals and medical records. The specialist will evaluate your facial anatomy, skin type, and determine how much product is needed for the best outcome.

A topical anesthetic or local anesthetic may be applied to ensure comfort. The filler is then carefully placed into the treated areas using precise injections. Your practitioner may gently massage the area to ensure even distribution of the filler.

What to Expect During the Procedure

The process typically takes 30–45 minutes. Depending on whether you’re receiving Restylane Defyne, Refyne, or Lyft, the practitioner will adjust the depth and placement of the injections. Because these dermal fillers are designed to restore volume, results are often seen immediately.

Aftercare and Recovery

Mild redness, swelling, or bruising may occur after treatment, but these effects typically subside within a few days. For the best recovery:

  • Avoid touching or pressing the treated area for 24 hours;
  • Skip strenuous exercise and alcohol for a day;
  • Stay away from extreme heat or cold;
  • Use gentle skincare and avoid exfoliation temporarily.

Most patients resume normal activities right away. Follow up treatments may be suggested to maintain long-term correction of nasolabial folds and marionette lines, especially if your goals include sustained improvement over time.

Expected Results and Longevity

Depending on the specific product used, results from Restylane Defyne, Refyne, or Lyft can last from 6 to 12 months. The longevity varies among patients due to factors like metabolism, age, and lifestyle.

Every face is unique, and individual results depend on skin condition and treatment plan. The natural elasticity and flexibility of Restylane Defyne and Refyne help maintain expressiveness, allowing patients to enjoy rejuvenation that looks and feels authentic.

Both Radiesse and Restylane are trusted dermal fillers for reducing wrinkles and restoring volume, though Restylane’s hyaluronic acid composition offers more flexibility and natural facial movement.

Comparing Restylane with Other Treatments

While Restylane treatments are highly effective for lines and nasolabial folds, some patients may combine them with various treatments such as laser resurfacing or neuromodulators for enhanced smoothing and contouring.

Unlike surgery, filler treatments require no downtime and are reversible, offering flexibility to refine results gradually. The versatility of Restylane products makes them a preferred choice for patients seeking non-invasive rejuvenation.

Safety, Comfort, and Possible Side Effects

Restylane’s safety record is well established, with thousands of patients treated worldwide. However, as with any injections, some side effects may include:

  • Temporary swelling and bruising;
  • Redness or tenderness in treated areas;
  • Minor lumps or unevenness (which usually resolve quickly);
  • Mild itching or tightness.

These are usually temporary and resolve naturally. To minimize risk, it’s essential to choose a qualified professional experienced with Restylane injections and dermal fillers. Always seek a trusted provider of Restylane fillers who follows the highest medical standards and uses authentic products for the lasting results.

Maintaining Your More Youthful Look

To preserve a more youthful look, proper skincare and periodic follow up treatments are recommended. Over time, the hyaluronic acid naturally breaks down and is absorbed by the body, making maintenance sessions ideal for continued improvement.

Your provider may adjust the choice of Restylane Defyne, Refyne, or Lyft depending on changes in your facial structure and the depth of your nasolabial folds.

Conclusion: The Power of Restylane for Smile Lines

When it comes to addressing nasolabial folds, marionette and smile lines, Restylane stands as one of the most advanced solutions in aesthetic medicine. The combination of innovative Xpreshan technology, biocompatible hyaluronic acid, and precisely engineered gel formulations allows practitioners to restore volume, smooth contours, and achieve stunning, natural results.

Whether you choose Restylane Defyne for deeper folds, Refyne for moderate correction, Lyft for enhanced volume in the cheeks, nose, or chin, or Silk for enhancing lips, the treatment delivers refined rejuvenation tailored to your aesthetic goals. By working closely with skilled professionals and maintaining consistent care, patients can enjoy long-lasting improvement in lines and nasolabial folds — and the confidence of a refreshed, radiant smile.
