The possibly significant occasions are sequelae as a result of systemic spread of toxin bringing about botulism-like characteristics or systemic anaphylactic reactions. The cosmetic usage of botulinum toxin almost never causes significant side effects. The frequency of serious side effects is 33 periods larger for therapeutic than for beauty scenarios. The median botulinum toxin dose is 4 periods larger in experiences for therapeutic cases than cosmetic conditions [22].
