That first notice of laugh lines etching your face can be jolting. Those smiling creases that once charmed now seem to age your appearance beyond your years.

But you’re not alone – laugh lines are a rite of passage most of us go through. The good news? You’ve got options to turn back time.

In this complete guide, Dr. Soni from Ethos Spa will tell you everything you need to know about smoothing laugh lines with dermal fillers

From understanding what causes them to choosing the right injectable, you’ll learn how fillers can rejuvenate your smile without going under the knife. Let’s get started!

What Are Laugh Lines and What Causes Them?

Laugh lines, or nasolabial folds, are the lines that extend from the corners of your nose to the edges of your mouth. They form as we age and the fat pads in our cheeks start to diminish.

This loss of facial volume leads to visible creases around the mouth and cheeks. Laugh lines also deepen as our skin loses elasticity and collagen over time.

Causes of Nasolabial Folds

Muscle ContractionRepeated levator muscle contraction during facial expressions causes tissue expansion in the cheek fat pad, leading to nasolabial folds. J. Owsley et al., 2008
Soft Tissue InteractionThe folds result from a conflict between the skin and fat envelope on one side and the underlying muscles on the other. J. Zufferey, 1992
Cheek Mass ChangesAging-related changes in the cheek mass and its support contribute to the deepening of these folds. N. Yousif et al., 1994
Loss of Cheek FatLoss of volume in the deep medial cheek fat is an additional determinant of nasolabial folds. Rod J. Rohrich et al., 2008
Facial MusclesTwo facial muscles may significantly contribute to the prominence of nasolabial folds as one ages. J. Pessa et al., 1993

While genetics plays a role, sun damage is another culprit that can exacerbate their appearance. And of course, all that smiling, laughing, and repetitive facial expressions etch the folds more over the years. The end result? Those parenthesis-shaped lines that can make us look older than we feel.

Can Dermal Fillers Smooth Out Laugh Lines?

The short answer – absolutely! Dermal fillers are one of the most effective treatments for softening the appearance of laugh lines and restoring a more youthful look. Here’s how they work:

How Do Fillers Plump Up Laugh Lines?

Dermal fillers add volume underneath the skin to fill in creases and folds. Injectable gels provide structure that lifts depressed areas along the nasolabial folds. The added volume reconstructs the fat pads that were lost to aging. This plumps up laugh lines from the inside out.

Do Fillers Stimulate Your Skin’s Own Collagen?

Many dermal fillers, especially those containing hyaluronic acid, stimulate collagen production in your skin. This ramps up your skin’s natural plumping capacities. The boosted collagen builds firmer skin tissue in the dermis layer, smoothing out lines even after the gel absorbs.

Can Dermal Fillers Relax Laugh Lines?

Some fillers contain lidocaine, an anesthetic that provides immediate relaxing of the muscle contractions creating laugh lines. This delivers an instant softening effect following treatment. Results build over the next few weeks as the collagen stimulation kicks in.

To summarize, dermal fillers both fill in lost volume and rejuvenate the skin’s structure. This dual action works to smooth away those telltale laugh lines around the mouth.

What Are the Best Dermal Fillers for Laugh Lines?

With many types of dermal fillers available, choosing the right injectable for your laugh lines is key. Here are top options recommended by experts:

Hyaluronic Acid Fillers

Hyaluronic acid (HA) fillers like Juvederm and Restylane are the most popular for laugh lines. HA has high water-binding properties that add natural-looking volume. These fillers come in formulations tailored for specific areas. For example:

  • Restylane Defyne has a flexible gel that integrates motions around the mouth.
  • Juvederm Voluma works well for age-related cheek hollowness.
  • Restylane Refyne contains wrinkle-smoothing lidocaine.

Collagen Stimulating Fillers

Sculptra and Radiesse fillers promote your body’s natural collagen production. This creates longer lasting, smoother looking skin. The effects build gradually over months. These work well for severely set-in laugh lines.

Synthetic Fillers

Advanced fillers like Bellafill contain synthetic collagen for the most permanent, wrinkle-relaxing results. However, these aren’t reversible like HA fillers. Make sure you’re ready for long lasting change.

How is Dermal Filler Injected for Laugh Lines?

Ready to smooth those bothersome laugh lines?

Dr. Soni shares what to expect during a dermal filler treatment session:

Numbing and Marking

Dr. Soni will first apply a topical anesthetic cream followed by small injections around the treatment area. This minimizes discomfort. Guide markings may be made on your laugh lines.

Injecting the Filler

Using an ultrafine needle, Dr. Soni will skillfully inject the filler into the indented areas of your laugh lines. This is where precision technique is key for natural looking results.

Molding the Filler

After injecting, Dr. Soni may lightly massage the area to ensure proper contouring and placement of the filler. This smooths and blends the product.

Minimizing Side Effects

Ice packs are often applied after to reduce swelling and tenderness. Dr. Soni will review what to expect post-treatment and how to care for your skin.

Overall, dermal filler sessions only take around 30 minutes. While individual pain thresholds vary, many experience nothing beyond mild discomfort. Any side effects like bruising are temporary.

How Long Do Laugh Line Fillers Last?

Fillers designed for laugh lines and facial folds typically last 6-18 months. Hyaluronic acid fillers are reversible, so they aren’t permanent. Your body naturally absorbs the gel over time. Maintenance touch up sessions can sustain your smooth, youthful look.
