What Is the Masseter Botox (Jaw Botox)?
Masseter Botox (Jaw Botox) is a precisely targeted injection of Botulinum toxin into the masseter muscles — the large chewing muscles on either side of the jaw. By relaxing these muscles, the treatment reduces their bulk over time, resulting in a visibly slimmer, softer lower face and a more feminine or elegant facial oval.
This is one of the most popular aesthetic treatments in Korea, where a defined V-line profile is highly valued. Results are progressive and natural-looking, typically visible within 4–6 weeks.

Why Choose the Masseter Botox (Jaw Botox)?
A wide or square jaw caused by masseter hypertrophy cannot be improved by diet, exercise, or skincare. Masseter Botox is the only non-surgical treatment that directly reduces the muscle responsible for jaw width — producing a visible V-line effect that no other non-surgical intervention can replicate. Our Korean physicians are highly specialized in this treatment.
- Only non-surgical solution for muscular jaw width
- Expert Korean V-line technique
- Natural progressive slimming over weeks

How Masseter Botox Works
The physician identifies and marks the masseter muscle boundaries for each patient — muscle size varies significantly between individuals and accurate mapping is essential for natural results. Botulinum toxin is then injected at 2–4 strategic points per side at the correct intramuscular depth.
Over 4–6 weeks, the masseter muscle gradually atrophies due to reduced nerve stimulation — becoming thinner and smaller. The jawline visibly narrows and softens as the bulk reduces, creating the characteristic V-line slimming effect. Chewing function is fully preserved as surrounding muscles compensate.
