When people are just starting to get Botox treatments one of their legitimate concerns that they express to me is, can the Botox travel to other parts of their body and cause something dangerous? Or act in a place that we don’t want it to act? And I’m happy to tell you the answer is, No. When Botox is injected into the skin or into the muscle, the two most common places where it is injected, it’s almost immediately absorbed onto the surface of nerves. There’s a great chemical attraction between the Botox molecule and the outside lining of the nerves. Once it’s attracted there and absorbed onto the outside of the nerve, thru chemical processes it then goes inside the nerve and that’s irreversible. It can’t then go out of the nerve and go somewhere else. That binding occurs within an hour, within an hour and a half of the time the medicine is injected and at that point the Botox just can’t do anything else. By the way, the way the Botox works is by being inside that nerve, it then stops the nerve that are releasing the chemicals that are the messengers that go to the muscle and tell the muscle to contract. So if the nerve can’t release those messengers then the muscle can’t contract and that’s how the Botox does for you what you want it to do. Well, then some people take that issue to an extreme and say, what happens, if in the course of the injection instead of the Botox going to the skin or into the muscle, it actually goes into a blood vessel? Certainly if it goes into a blood vessel then it can travel to other parts of the body, and that’s true. But please understand, most injections of Botox are no more than 4 or 5 units of Botox. Sure, in the course of a facial treatment you may get a total from 20 to 75 units, but no more than 4 or 5 units in an injection. In order for the Botox to do damage in your bloodstream where it’s distributed throughout your entire body, you’d have to have thousands and thousands of units of Botox, not 5 units. So let me give you every reassurance. Botox is not dangerous; it can’t spread to other parts of your body and if you have a Botox treatment enjoy what it does for you and enjoy how it makes you look better.
