They say that laughter is the best medicine, but years of joy can leave behind permanent reminders in the form of deep creases running from the nose to the corners of the mouth. Known medically as nasolabial folds, these “laugh lines” can make you look tired or older than you feel, even when your face is at rest.

In 2026, treating these lines is no longer just about “filling the gap.” Modern aesthetic medicine focuses on structural support and natural movement. At LIV Clinic in Koh Samui, we specialize in dermal fillers for laugh lines using advanced techniques that smooth these shadows without creating a stiff or puffy look. Whether you are looking to soften a mild line or lift a deep fold, our goal is to refresh your face so you can keep smiling with confidence.

Why Trust LIV Clinic for Mid-Face Rejuvenation?

Treating nasolabial folds is an art. If an injector simply fills the line directly without assessing the cause, the result can often look heavy or “monkey-like.” At LIV Clinic, Dr. Narathai Vichienkalayarut takes a holistic approach.

Often, deep laugh lines are caused by sagging cheeks that have lost volume and dropped forward. In these cases, Dr. Narathai may recommend lifting the cheekbones first to naturally pull the skin back, rather than just filling the line itself. We use only premium, FDA-approved Hyaluronic Acid fillers that move naturally with your expressions. We verify every box with you, ensuring safety and authenticity in every syringe.

Understanding the Cause: Volume Loss vs. Muscle Action

Before we inject, we determine the root cause of your lines to choose the right product.

• Volume Loss: As facial fat pads shrink and gravity takes over, the cheek tissue descends, creating a heavy fold. This requires a structural filler.

• Repetitive Movement: If you have very expressive muscles, the skin creases constantly. This requires a flexible filler that stretches when you smile.

Best Brands for Laugh Lines: Juvederm vs. Restylane

We offer the top two global brands, each with specific products designed for this high-movement area.

1. Restylane Refyne / Defyne (The Flexible Choice)

Using XpresHAn Technology™, these fillers are designed to be flexible. They stretch and recoil like natural skin.

• Best For: Patients who are very expressive. It ensures you don’t look “stiff” when you laugh.

• Longevity: 12 months.

2. Juvederm Vollure / Volift (The Smooth Choice)

Part of the Vycross family, this filler is incredibly smooth and durable.

• Best For: Softening moderate to severe folds with a very natural, seamless finish.

• Longevity: Up to 18 months.

3. Neuramis Deep (The Value Choice)

A high-quality Korean filler that provides excellent volume and lift at a more accessible price point.

• Best For: Deep static folds that need significant structural support.

Dosage Guide: How Much Filler Do I Need?

One of the most common questions is about the number of syringes required. This depends on the depth of your folds.

The Procedure: What to Expect

We aim to make your experience as comfortable as a spa treatment.

1. Numbing: We apply a potent numbing cream for 30 minutes.

2. Cannula Technique: For this area, Dr. Narathai often prefers using a blunt cannula instead of a sharp needle. A cannula slides under the skin, minimizing trauma to blood vessels.

3. The Injection: The filler is placed carefully in the deep dermis or subdermal layer.

4. Immediate Result: You will see the shadow disappear instantly. The area will look smoother and younger before you even leave the chair.

Safety and “The Danger Zone”

The nasolabial fold is near a major artery (the facial artery). Injecting incorrectly here can cause serious complications. This is why you should never choose a budget clinic or an unlicensed injector for this specific treatment.

At LIV Clinic, safety is our obsession. We aspirate (check for blood) before injecting and use cannulas to avoid arteries. We also keep Hyaluronidase (the dissolving enzyme) on hand at all times as a safety protocol, giving you total peace of mind.

Aftercare for Long-Lasting Results

• Avoid Makeup: Keep the area clean for 12 hours to prevent infection.

• No Pressure: Do not sleep on your face or get a face massage for 2 weeks.

• Stay Cool: Avoid saunas or hot yoga for 48 hours to minimize swelling.

• Hydrate: Drink plenty of water to help the Hyaluronic Acid expand and hydrate the skin.

Frequently Asked Questions

Will filling these lines make my face look fat? No. This is a common myth. “Chipmunk cheeks” happen when a doctor overfills the area. Dr. Narathai uses a conservative approach, placing just enough filler to soften the shadow without creating a bulge.

How long does the swelling last? Swelling in this area is usually mild to moderate. You may look slightly “puffy” for 2-3 days. By day 14, the filler softens and looks completely natural.

Can I smile immediately after? Yes! In fact, we want you to smile so we can see how the filler moves with your face. You might feel a little stiff for the first few days, but this sensation fades quickly.

Is it better to lift the cheeks or fill the lines? Ideally, both. Lifting the cheeks pulls the skin back, treating the cause of the fold. Filling the line treats the symptom. A combination approach often yields the most natural result.

Does it hurt? Most patients rate it a 3/10. The numbing cream works very well, and the filler itself contains lidocaine.
