For those seeking to diminish the appearance of lines that extend downwards from the corners of the mouth towards the chin, often called smile lines, marionette lines, or oral commissure lines, Smile Line Filler treatment has become an increasingly popular and effective non-surgical solution. These lines can create a sad, angry, or perpetually downturned expression, even when one is feeling cheerful.

Korean dermatology and aesthetic clinics, especially those in Seoul, are renowned for their subtle, refined approach to facial enhancements. You won't walk out with an overfilled or unnatural appearance—you’ll gain smoother, more uplifted mouth corners, and a refreshed, confident, and approachable expression that truly enhances your natural beauty.

Cost of Smile Line Filler Treatment in Korea

Smile Line Filler in Korea offers high-quality results at a cost-effective price compared to many Western countries. Prices may vary depending on the brand of hyaluronic acid (HA) filler used (such as Restylane, Juvederm, Teosyal, Neuramis, or Elravie), the amount of filler injected (typically measured in milliliters), and the depth and extent of the lines.

• Smile Line (Marionette Line) Filler (per 1ml syringe): ₩250,000–₩700,000+ (approx. $180–$505+ USD, based on current exchange rates of July 2025).
• Note: Typically, 1ml to 2ml of filler is used for both sides to achieve a natural correction, depending on the severity of the lines. Softer to medium-density HA fillers are generally chosen for this area to provide smooth, natural-looking volume and lift. This treatment is often combined with a small amount of Botox to relax the DAO (depressor anguli oris) muscle, which pulls the mouth corners down, for more comprehensive results.

Most clinics use reputable and KFDA (Korean Food and Drug Administration) approved brands, ensuring product quality and safety. Popular domestic Korean brands like Neuramis and Elravie offer excellent quality at more accessible price points.

What Are Smile Lines (Marionette Lines) and How Does Filler Work?

Marionette lines are common concerns that arise due to:

• Aging: Natural loss of collagen, elastin, and fat in the lower face, coupled with bone resorption around the jaw.
• Gravity: The continuous downward pull on facial tissues.
• Muscle Activity: Overactivity of the depressor anguli oris (DAO) muscle, which pulls the corners of the mouth down.
• Genetics: Some individuals are predisposed to developing these lines earlier or more deeply.
• Sun Damage: UV exposure accelerates skin aging and collagen breakdown.

Smile Line Filler treatment primarily uses hyaluronic acid (HA) based gels, which are naturally occurring substances in the body that attract and hold water. When precisely injected into the marionette lines, HA fillers work by:

• Filling and Lifting: Directly plumping up the depressed lines from beneath the skin, making them shallower and less visible.
• Providing Support: Lifting the corners of the mouth to counteract the downward pull and restore a more neutral or slightly upturned expression.
• Improving Skin Texture and Hydration: HA attracts water, improving the hydration and elasticity of the skin in the treated area.
• Creating a Smoother Transition: Blending the lines more seamlessly with the surrounding chin and jawline area, leading to a more youthful and approachable appearance.

This procedure requires an injector with advanced knowledge of lower facial anatomy and precise injection techniques to achieve optimal, natural-looking results, avoiding overcorrection or an unnatural appearance.

What to Expect During Treatment

1. Consultation & Assessment: A board-certified dermatologist or aesthetic physician will conduct a thorough consultation, meticulously assessing the depth and cause of your smile lines (e.g., primary volume loss vs. muscle activity vs. sagging skin). They will discuss your aesthetic goals, explain the procedure, potential combinations with other treatments (like chin filler, jawline filler, or Botox), and answer any questions.
2. Numbing & Marking: A topical numbing cream will be applied to the treatment area to ensure comfort during the injections. The injector will precisely mark the injection points along the marionette lines and at the oral commissures.
3. Precise Injection Session: Using very fine needles or cannulas (a blunt-tipped instrument that minimizes bruising and swelling), the filler will be carefully injected into the targeted lines. The injector will gently massage the area to ensure even distribution and a smooth result. If Botox for DAO is also used, it will be injected strategically. The procedure typically takes 15–30 minutes.
4. Immediate Aftercare & Return to Activities: You may experience mild swelling, redness, or tenderness immediately after the treatment. Minor bruising is possible. Ice packs can be applied to minimize these effects. There is typically minimal to no downtime, and you can generally resume normal light activities immediately. Strenuous exercise, excessive facial manipulation (e.g., strong rubbing), and lying completely flat should be avoided for 24-48 hours.
5. Results Timeline:

• Immediate improvement in line depth is often visible right after the treatment.
• Swelling and any minor bruising usually subside within 24–72 hours, revealing the more refined smoothness.
• Final results are typically seen within 1-2 weeks once any swelling has completely resolved and the filler has settled. If Botox is combined, its effects will gradually appear over 3-7 days.
• Results generally last 9–18 months, depending on the type of filler used, individual metabolism, and lifestyle. Maintenance sessions are recommended to sustain the desired smoothness and rejuvenated appearance.
