A jaw that looks wide because the masseter muscle is developed can be considered for botulinum toxin consultation. If the main cause is the width of the jawbone or fat, it's hard to achieve the desired contour with just muscle injections.
Before your consultation
- Is the part that sticks out when I clench my teeth muscle?
- How do I tell the difference between bone and fat?
- Can I get it even if I don't have much facial fat?
General information, not a personal diagnosis or treatment plan. Suitability, risks and recovery require an individual consultation.
Is the part that sticks out when I clench my teeth muscle?
The masseter muscle is the muscle that moves when you chew. During consultation, we compare the relaxed state and clenched state, and check the size of the muscle and left-right differences. The results of clinical trials for masseter muscle hypertrophy cannot be applied to all faces with wide jawbones. Don't try to determine the cause just by feeling it yourself.

How do I tell the difference between bone and fat?
Don't just look at the front width; you should also evaluate the chin tip, under the ears, and the thickness of the cheeks. The questions are different for the distinct contours that remain after fat loss and the treatment areas that only become prominent when chewing. The necessary tests are determined based on the examination results, and you don't need to take pictures just because you're getting cosmetic injections.
Can I get it even if I don't have much facial fat?
If your cheeks are already sunken or the skin below is sagging, make sure to first get an explanation of how the overall appearance will change after the muscle volume decreases. Making it smaller and achieving balance are not the same goal. It helps to have recent weight change info and photos from previous contour procedures.
Can the chewing strength change too?
Since the target is the masseter muscle, you should discuss the possibility that the feeling of chewing hard foods might change. If you usually chew on one side or have jaw pain, mention cosmetic goals and functional issues separately. It's more accurate not to expect that a single jaw reduction injection will solve the cause of jaw joint noise or pain.
How should I take the result photos?
Distinguish between photos where you're clenching your teeth and those where your face is relaxed, and record them from the same angle and distance. The jaw width can look different depending on the camera lens or if you tilt your head. During your next visit, it's good to evaluate not just how much it has decreased, but also any discomfort while eating, asymmetry when smiling, and whether it matches the impression you wanted.
What do they ask about at the Dongseong-ro consultation?
If you're looking into jaw botulinum toxin at Daegu Dongseong-ro, the first question to ask is, “How much of my face is made up of muscle?” You can check jaw botulinum toxin in the official Doctor Designer Daegu treatment list, and the product name, dosage, and reassessment plan should be explained individually during the consultation.
