Botulism toxins are produced by bacteria of the genus Clostridium, namely Clostridium botulinum, C. butyricum, C. baratii and C. argentinense, which are widely distributed, including in soil and dust. As well, the bacteria can be found inside homes on floors, carpet, and countertops even after cleaning. Some food products such as honey can contain amounts of the bacteria.
In the before and after picture of my mom's Botox treatment, my mom paid $350 and was charged per area. She chooses reputable physicians that may be slightly more expensive than average, but have good patient reviews and are well-trained and skilled. To her, it is more worth it to have a doctor who knows how to cater the right technique to her skin issues than to have a doctor who injects her with a certain quantity of Botox but with poor or ineffective technique. This doesn't mean that the more expensive a doctor is, the better he or she will be. It just means that similar to how you would hesitate if the treatment is really expensive, you should also hesitate if the Botox treatment is really inexpensive. Good Botox requires a skilled hand and this is especially important since Botox is a treatment that can definitely be botched.
The Botox used for migraines and the Botox used for cosmetic procedures is actually exactly the same. "Basically, young and middle-aged women were getting [Botox] for cosmetic purposes, and that’s the most common person that has migraines, and that’s how they figured out it was helpful," Ravitz tells me. Women were getting Botox for aesthetic reasons and happened to notice relief from their migraine symptoms, and doctors began looking into it as a direct treatment. In fact, women are disproportionately affected by migraines — about 85 percent of chronic-migraine sufferers are women, and the condition affects 28 million in just the U.S.
Botulinum toxin exerts its effect by cleaving key proteins required for nerve activation. First, the toxin binds specifically to nerves which use the neurotransmitter acetylcholine. Once bound to the nerve terminal, the neuron takes up the toxin into a vesicle. As the vesicle moves farther into the cell, it acidifies, activating a portion of the toxin which triggers it to push across the vesicle membrane and into the cell cytoplasm. Once inside the cytoplasm, the toxin cleaves SNARE proteins preventing the cell from releasing vesicles of neurotransmitter. This stops nerve signaling, leading to paralysis.
