For those seeking to achieve a more slender, V-line facial shape, reduce a bulky or square jawline, or alleviate symptoms of teeth grinding (bruxism) and TMJ discomfort without surgery, Masseter Botox has become an exceptionally popular and effective non-surgical solution. This targeted treatment refines the lower face contour, creating a softer and more feminine or balanced appearance. In Korea, Masseter Botox treatments are performed with meticulous precision and artistry, making it a leading global destination for safe, affordable, and natural-looking facial contouring and therapeutic relief.

Korean dermatology clinics, especially those in Seoul, are renowned for their subtle, refined approach to facial aesthetics. You won't walk out with an unnatural or stiff jaw—you’ll gain a more harmonious, balanced, and confident facial contour that enhances your natural beauty.

Cost of Masseter Botox Treatment in Korea

Masseter Botox in Korea offers high-quality results at a cost-effective price compared to many Western countries. Prices may vary depending on the brand of botulinum toxin used (such as Allergan Botox, Xeomin, Nabota, or Botulax) and the number of units required, which is determined by the size and strength of your masseter muscles.

• Jaw Reduction (Masseter Botox): ₩90,000–₩200,000 (approx. $65–$145 USD, based on current exchange rates of July 2025).
• Note: The number of units can vary, typically ranging from 25-50 units per side, depending on muscle size and desired effect.

Most clinics use brands like Botox (Allergan), Xeomin, Nabota, and Botulax—many of which are KMFDS and FDA approved, ensuring product quality and safety.

What Is Masseter Botox and How Does It Work?

Masseter Botox involves injecting Botulinum Toxin Type A into the masseter muscles, which are the large chewing muscles located at the angles of the jaw. These muscles can become enlarged due to genetics, habits like teeth grinding, or frequent chewing, leading to a wider lower face. When injected in small, controlled doses, the neurotoxin temporarily relaxes these muscle fibers by blocking nerve signals. This strategic relaxation helps to:

• Slim a bulky or square jawline, creating a more aesthetically pleasing V-line facial shape.
• Reduce the size of enlarged masseter muscles, leading to a softer and more feminine or balanced lower face contour.
• Alleviate symptoms of bruxism (teeth grinding) and TMJ (temporomandibular joint) pain and discomfort by relaxing the overworked chewing muscles.
• Prevent the deepening of current lines that can form around the jaw due to muscle tension.

It’s important to remember that Botox doesn't remove bone or fat; instead, it relaxes and gradually shrinks the muscle, resulting in a refined facial silhouette.

What to Expect During Treatment

1. Consultation & Marking: A board-certified dermatologist will meticulously assess your facial structure, evaluate the size and strength of your masseter muscles, and discuss your aesthetic goals (e.g., V-line, tension relief). They will then precisely mark the injection points to ensure a natural-looking and effective result.
2. Quick Injection Session: The procedure is minimally invasive and typically takes 5–15 minutes with minimal discomfort. Injections are generally well-tolerated, and numbing cream is usually not necessary but can be applied if preferred.
3. Immediate Return to Activities: There's no downtime required. You can generally resume your normal daily activities immediately after the session. Minor redness or swelling at the injection sites, if any, usually resolves within a few hours.
4. Results Timeline:

• Initial effects of muscle relaxation typically begin within 3–7 days.
• Visible jaw slimming will gradually become apparent over 2–4 weeks as the muscle atrophy occurs.
• Peak results are usually observed around 1-2 months after the injection.
• Results generally last 4–6 months, and regular maintenance sessions are recommended to sustain the desired facial contour and therapeutic benefits.
