Can botox filler migrate from one body part to another?

Although there are some rare reports of migration of neuromodulators like Botox, these treatments are generally safe and effective if done properly by trained providers.  As always, it is important to do your homework before choosing your medical provider for various treatments or procedures.  You want to make sure they are board certified in the relevant specialty.  For example, if you are looking to have a breast augmentation or tummy tuck, do you want your surgeon to be board certified in otolaryngology/ENT(ear, nose and throat)?  Or Plastic Surgery?
