Jaw Botox

Jaw Botox

Refining well-developed jaw muscles for a softer facial contour

About Procedure

About Jaw Botox

Jaw Botox is a procedure that injects botulinum toxin into the masseter (chewing muscle) to gradually reduce the volume of overdeveloped muscle, softening a square jawline for a gentler impression.

Changes appear gradually as muscle activity decreases, and it may also help when the jaw muscles have become firm from teeth grinding or clenching habits. You can choose your preferred product from Korean-made, Coretox, The Toxin, Xeomin, and Allergan.

At Sia Clinic Daejeon, we check muscle thickness, left-right symmetry, and chewing habits, then design the injection points and dosage (standard 50U) for each individual.

FAQ

FAQ

Q.  When do results appear?
Muscle volume usually decreases gradually over 2–4 weeks, and many people notice changes during this period. The timing and degree of change may vary depending on muscle volume and the individual.
Q.  How do I choose a Botox product?
You can choose from Korean-made, Coretox, The Toxin, Xeomin, and Allergan. Coretox and Xeomin are products with reduced or removed complexing proteins, often considered by those who want to lower concerns about resistance with repeated treatments. Let us know about your previous treatment experience and we will guide you during consultation.
Q.  Will chewing feel uncomfortable?
Early after treatment, you may feel slightly less strength when chewing tough foods, but in most cases it does not interfere with daily life. The degree felt varies by individual.
Q.  Are there cases where the jaw does not become slimmer?
If the jaw looks wide because of bone structure or fat rather than muscle, the change may be minimal. During consultation, we identify the cause and may also suggest other options such as contour injections.
