Botox for a Square Jaw
Jaw Botox
Botox for a square jaw is a procedure that involves injecting botulinum toxin into the masseter muscle—whichmakes the jawline appear more angular — to reduce the size of the overdeveloped muscle. If your square jaw is caused by muscle rather than bone, you can expect a change in your facial contour without surgery.
When the toxin blocks the nerve signals transmitted to the muscles, it reduces excessive use of the masseter muscle, and over time, the muscle volume gradually decreases, resulting in a slimmer, more defined jawline.
The procedure takes less than 10 minutes and requires almost no recovery time, so you can comfortably have it done as part of your daily routine. Repeating the procedure at regular intervalsslows down muscle regrowth, allowing you to maintain a slimmer contour for longer.
Why Jaw Botox
It may be the muscles, not the bones, that change your face shape
A muscular square jaw is caused by a well-developed masseter muscle.
Square Jaw Botox works precisely on the masseter muscle to refine the jawline without surgery.
Point 01
Reduces muscle size without surgery,
The masseter muscle is used for chewing food, and if it becomes overly developed—due to eating tough foods or the habit of clenching one’s teeth—the jawline may appear more prominent. Botox for a square jaw works by relaxing this muscle, reducing its activity and gradually decreasing its volume.
- Improve your jawline with injections alone—no incisions or surgery required
- Reduce the volume of the masseter muscle developed due to chewing habits
- Repeated treatments slow muscle regrowth, improving results
Point 02
Where and how deep.
The injection site determines the outcome.
The masseter muscle is surrounded by facial muscles that control the corners of the mouth and salivary glands. If the injection site is off-target, it can result in an unnatural smile or unwanted changes; therefore, we confirm the area of the masseter muscle that can be felt when clenching the molars and inject precisely only within the safe zone.
-
Injection Depth — Muscle Layer
Injected deep into the masseter muscle rather than the skin, it acts specifically on the muscle
-
Injection Site — Lower Safety Zone of the Masseter Muscle
Inject the solution primarily into the lower portion, where the masseter muscle is thickest, taking care to avoid the facial muscles and salivary glands.
-
Volume Adjustment — Units Tailored to the Thickness of the Bite
Adjust the volume based on the muscle thickness and left-right differences confirmed through palpation
How It Works
How Botox Works for a Square Jaw
, which becomes prominent when you bite down on your molars, is the exact spot where the toxin is injected
Nerve signals transmitted to the muscles are reduced,
resulting in less overuse of the masseter muscle
As muscle volume gradually decreases,
the jawline becomes slimmer and more defined.

The Episode Difference
Why It's Different
Every process has its own unique reason.
01
You need to understand this thoroughly so that you can perform the procedure more effectively:
.
Through a pre-treatment examination and consultation, we assess the thickness of the masseter muscle, any asymmetry between the left and right sides, and chewing habits, and after determining whether the patient has a muscle-related square jaw, we decide on the injection volume and placement.
ANALYSIS02
The masseter muscle is divided into two layers
.
SB(superficial belly) 혹은 DB(deep belly) 한 가지 층에만 주입하면 중간의 DIT(deep inferior tendon)층이 약물의 흐름을 가로막아 반쪽짜리 효과만 나타납니다. 층별 나눔 주입 기법으로 최대의 효과를 나타냅니다.
