Cosmetic injections use a neurotoxin produced by a bacterium commonly found on plants, in soil, in water, and in animals’ intestinal tracts. You know it better as the “miracle poison.” Better yet, it may be most familiar under the brand name Botox. (While Botox is a well-known brand name, it is not the only brand under which cosmetic injections are marketed. Cosmetic injections are also marketed under the brand names Dysport, Xeomin, Neurobloc and Myobloc.)
The miracle poison, Botox, is used in multiple fields of medicine, including by dentists to achieve patients’ cosmetic goals. Precisely located cosmetic injections eliminate dynamic wrinkles — wrinkles caused by the movement of muscles in your face — by “inhibiting transmission of alpha motor neurons at the neuromuscular junction.” In easier-to-appreciate English, that means that the Botox paralyzes the muscle that produces the wrinkle by preventing the release of the neurotransmitter acetylcholine. Preventing the release of that neurotransmitter prevents the muscle that could produce the muscle from being activated by the nerve. The effect of the application of Botox, then, is to smoothen lines and creases that would otherwise have appeared.
