Masseter Botox Korea | Jaw Slimming & V-Line Contouring at Busan Seomyeon ONE Clinic

Masseter Botox is one of Korea's most popular non-surgical facial contouring treatments for creating a slimmer, more refined jawline while also relieving jaw tension and teeth grinding. At Busan Seomyeon ONE Clinic, we provide personalized Masseter Botox treatments using premium botulinum toxin products and advanced injection techniques to reduce enlarged chewing muscles safely and naturally. Conveniently located at 6F, Inje Medical New Building, 785 Gayadae-ro, Busanjin-gu, Busan, our clinic welcomes both Korean and international patients with English-friendly consultations and individualized treatment plans. Whether your goal is to achieve a softer V-line appearance, reduce a square jaw, improve facial balance, or relieve discomfort caused by bruxism or jaw clenching, our experienced medical professionals carefully assess your facial anatomy and muscle strength to create results that enhance your natural beauty without surgery. Masseter Botox remains one of the most effective minimally invasive treatments for patients whose wide jawline is caused primarily by enlarged jaw muscles rather than bone structure. 

Why Choose Masseter Botox?

Many people have a wide lower face because of enlarged masseter muscles rather than prominent jawbones. Relaxing these muscles allows them to gradually become smaller, producing a slimmer and softer facial contour over time.

Benefits include:

• Non-surgical jawline slimming
• Natural V-line facial contour
• Softer lower facial appearance
• Reduction of enlarged masseter muscles
• Relief from teeth grinding (bruxism)
• Reduced jaw clenching and muscle tension
• Minimal discomfort
• Little to no downtime

Who Is a Good Candidate?

Masseter Botox is ideal for individuals who have:

• A square or broad jawline caused by enlarged muscles
• Overdeveloped chewing muscles
• Frequent teeth grinding
• Chronic jaw clenching
• Jaw tension or fatigue
• Mild facial asymmetry caused by uneven muscle size
• A desire for non-surgical facial slimming

During your consultation, our practitioners determine whether your facial width is caused primarily by muscle enlargement, bone structure, or both before recommending the most suitable treatment plan.

What to Expect During Treatment

Treatment begins with a comprehensive facial evaluation while you clench your teeth so the masseter muscles can be accurately assessed. Small amounts of botulinum toxin are then precisely injected into carefully selected areas of each muscle using very fine needles. The procedure usually takes only 10 to 20 minutes and requires virtually no downtime. Most patients return to work or sightseeing immediately after treatment. Muscle relaxation begins within one to two weeks, while visible facial slimming gradually develops over four to eight weeks as the muscles naturally decrease in size. Results typically last between four and six months before maintenance treatment is recommended.

FAQs

What is Masseter Botox?

Masseter Botox is a treatment that injects botulinum toxin into the masseter muscles, the large chewing muscles located at the angles of the jaw. By temporarily relaxing these muscles, they gradually become smaller, creating a slimmer jawline while also helping relieve jaw tension, teeth grinding, and muscle overactivity.

How long does it take to see results?

Most patients begin noticing muscle relaxation within one to two weeks. Visible facial slimming usually develops gradually over four to eight weeks as the masseter muscles decrease in size. The improvement appears natural because the muscle reduction occurs progressively rather than immediately.

How long do Masseter Botox results last?

Most patients enjoy results lasting approximately four to six months. Individual duration depends on muscle strength, metabolism, dosage, and lifestyle. Regular maintenance treatments help preserve long-term jawline contouring while continued treatments may gradually reduce muscle bulk over time.

Can Masseter Botox help with teeth grinding and TMJ symptoms?

Yes. In addition to improving facial contour, Masseter Botox is commonly used to reduce excessive jaw clenching, teeth grinding (bruxism), jaw fatigue, and muscle tension. Some patients with temporomandibular joint (TMJ)-related symptoms may also experience relief after treatment, although suitability should be assessed individually by a qualified practitioner.

Will my face look unnatural or affect my chewing?

When performed by experienced practitioners using appropriate dosing, Masseter Botox preserves normal facial expressions and everyday chewing function. Some patients may notice temporary mild chewing fatigue with very tough foods during the initial adjustment period, but the goal is always natural facial harmony rather than excessive slimming.

Is Masseter Botox suitable for international patients visiting Korea?

Absolutely. Busan Seomyeon ONE Clinic welcomes patients from around the world with English-friendly consultations, personalized treatment planning, premium botulinum toxin products, and comprehensive aftercare guidance. Our team ensures every international patient feels informed, comfortable, and confident throughout their treatment journey.
