How does botox work and what things can it be used for?
Botox is short for botulinum toxin type A.
There are actually 7 types of toxins, defined from A to G.
Botulinum toxin A is one of the neurotoxins produced by the bacteria, clostridium botulinum.
It produces a poison that paralyzes nerve endings.
So, how does it work?
Botulinum neurotoxins block the signals that tell your muscles to contract.
In essence, your muscles are paralyzed.
This could be a real problem if your respiratory muscles are paralyzed, making it impossible to breathe.
This is often the case in the botulism, a type of food poisoning.
However, used cosmetically, it can prevent smaller and specific muscles from contracting, such as those muscles that cause wrinkles.
Other conditions that botox can be used for are for neurologic disorders or uncontrollable spasms.
Botox therapy was approved by the FDA in 2002.
