How can Botox cause chipmunk cheeks? How long will it take to go away?

Thank you for your question.  I'm sorry you have such a poor eexperience with Botox.   Without knowing the injection pattern it is difficult to tell you what is going on.   Sounds like what possibly happened is that the Botox given for crows feet has been injected too low.   I'd follow up with your injector.   Be sure you are seeing an experienced injector.   Botox only lasts 3-4 months, so good news is, it's temporary.   Best of luck!

Botox should not cause swelling (and is rarely injected to the cheeks).   I suggest you see an expert for an evaluation to determine what is occurring.  Best, Dr. Emer.

Your crows feet injection is drifting into your midface and causing a problem.  Stop getting this service and find yourself a new injector.  

Thank you for sharing your question and I am sorry that your Botox results have not been what you anticipated.  Unfortunately without a series of photographs it is difficult to offer definite advice and I would discuss your results with your injector, or seek a second opinion as to the cause of your chipmunk cheeks.

Thank you for your question. I am sorry this has happened to you. This is the result of in proper injection around the crow’s feet area. If Botox is not injected close to the orbital rim or spreads beyond this area, then other muscles besides the orbicularis oculi will be affected. What is making your chipmunk cheeks is that the zygomaticus muscles (help lift the cheeks) have been affected. This can easily be avoided with proper technique. I recommend finding a new injector.
