General information, not a personal diagnosis or treatment plan. Suitability, risks and recovery require an individual consultation.
Is a slimmer jaw the same as a change in smiling?
Changes in jaw volume and mouth corner movements when smiling are different evaluation items. Botulinum toxin can cause unwanted changes, such as weakness in adjacent muscles, so the treatment area and symptoms must be checked together. Don't self-diagnose which muscles are affected just by looking at the pictures.

What video would help the consultation?
Take a short note of a relaxed expression, a light smile, and a big smile from the front. It is a good idea to prepare photos of yourself smiling naturally in the past so you can check the original left and right differences. Videos with the head tilted or filters applied may not be suitable for comparison.
Should I report changes in eating or speaking?
Rather than just mentioning the cosmetic appearance, describe any new discomfort in your chewing strength, lip movements, or speech. Recording when it started and whether it gradually improves will help you judge the progress. If you have difficulty swallowing or breathing, seek medical attention immediately rather than waiting until your scheduled return date.
Will injecting the other side restore symmetry?
Adding to the opposite side without determining the cause may cause further changes in the movement. After reviewing the existing injection location, dose, and asymmetry before the procedure, the person in charge should explain the options. Simply evaluate how symmetrical it looks in the mirror along with how comfortable it is with its features.
Which records should I keep for future treatment?
Please save the time when the discomfort disappeared, the previous product name, treatment area, and progress photos. Next, it would be a good idea to start by discussing whether repetition of the same approach is appropriate. Re-prioritize whether reducing face width is a necessary goal or preserving expression is more important.
How should I request a masseter treatment review in Dongseong-ro?
When requesting progress consultation from Daegu Dongseong-ro, please specifically inform us that the appearance of your smile has changed in addition to “confirming the effect.” It is a good idea to distinguish your current symptoms from the general description in the official chin botulinum toxin treatment list, and bring a record of the procedure if you received it elsewhere.
