Botox is a neurotoxin derived from Clostridium botulinum, an organism found in the natural environment where it is largely inactive and non-toxic. Facial Botox is used to reduce fine lines and wrinkles by paralyzing the underlying muscles. Botox injections are noted primarily for the ability to reduce the appearance of facial wrinkles. They’re also used to treat conditions such as neck spasms (cervical dystonia), excessive sweating (hyperhidrosis), an overactive bladder and lazy eye. Botox injections may also help prevent chronic migraines. Botox injections use a toxin called onobotulinumtoxinA to temporarily prevent a muscle from moving. This toxin is produced by the microbe that causes botulism, a type of food poisoning.
