I have larger masseter muscles (bite muscles) and recently received Botox injections in my jawline. Initially, I had 30 units of Botox on each side of my cheeks. Two weeks later, I had 10 units on the right side and 15 units on the left side of my cheeks. However, on the fourth day after my second injection, I noticed that my smile became crooked. Specifically, the right side (where I received 30 + 10 units) has a weaker smile compared to the left side. I'm curious to know how often this happens and whether it is caused by the injection area, the amount of injection, or the injection technique. Could it have affected a nerve or another muscle? When can I expect to recover from this issue, and are there any measures I can take to help improve it?
Sme of the Botox may have migrated to the zygomaticus major muscle, causing the slight difference in appearance. The good news is that it is not prominently noticeable and will resolve over time. Adjusting the placement of Botox lower in the future can help avoid this issue.
It appears that your smile has been affected by the Botox treatment in the masseter muscle. It is possible that some of the Botox migrated toward the jaw and affected the muscles involved in smiling. It usually takes about 3-4 months for the Botox to wear off and for your smile to return to normal. Best of luck!
Temporary asymmetry can occur with Botox injections around the mouth and jaw muscles. It may resolve over time, and evaluation by a physician can help determine if adjustments are needed.
Migration of injected product from the masseter muscles to other muscles controlling the lift of the smile can cause temporary asymmetry. This effect should improve as the product wears off. Consulting with an expert injector can provide more information and examples.
